Side by Side Comparison of: Lux vs Nest

Works well on my HVAC unit with emergency heat. Not all the features of my old thermostat (I wish it would switch from heating to cooling on it's own and would automatically switch to emergency heat if needed) but an affordable and quality item. The wiring for my old thermostat was not the same as any in the instructions. I just took a guess but before turning on I decided to call customer service. I don't think they had experience with the way my other thermostat was wired and they put me on hold for a bit. They confirmed that I had guessed correctly and I was set to go. I liked the fact that while it's physical size was smaller than my old thermostat, there was more room to accommodate the wires, so I could leave some extra wire in the case instead of having to push it all back into the wall.

I purchased this thermostat mainly for a specific feature that my old thermostat didn't have...the temperature swing setting. The old one was locked in at plus or minus 0.5 degrees. This was a problem because I discovered my air conditioner unit was oversized, so this plus the 0.5 degree swing setting was causing my AC unit to have short run times. This caused both inefficient compressor operation and humidity removal. After installing the the new Lux thermostat, I set the swing value to 5 (1.25 degrees), and my run times went from 5 minutes to a minimum of 10. I'm very happy with the results, and the cost was well worth it as I'm using less overall power for the same amount of cooling. Another thing I find very useful on the thermostat is the energy usage feature...It keeps track of the time the unit is on for the current day, previous day and total time since reset. This helps me keep track of my energy usage so I'm not surprised when I get my electric bill. I didn't have any issues installing or programing it. The instructions that came with it plus the ones I downloaded from the web were easy to understand.

I've owned Lux programmable thermostats for over 20 years and have 4 of them in my house currently. The back light stopped working on a 10 year old unit in my bedroom, so i decided to purchase this unit. Installation was extremely easy, uses the same mounting holes, but is considerable smaller than my old unit. This left me with an unpainted portion on my wall, which either needed to be painted or purchase the larger back plate. I choose to paint, which took all of 5 minutes. I read the instructions, downloaded the full user manual which was I read fully. The unit is extremely intuitive and, in the end, was a waste of my time to download and print the entire manual. The only setting that I changed was the recovery delay from 5 minutes to 2 minutes, which is done with a din switch on the back of the unit. Although we have only had this installed a few days now, we like it. The numbers a large enough to read without glasses, bright enough to see until it's dark and touching the unit anywhere lights it up for 10 seconds. Temporarily override and hold functions work the same as the older units, but are much easier to access. Finally, most utility companies are offering $25 back on the purchase of programmable thermostats and $100 back on WiFi enabled units. If this unit last as long as my others have, I'll be extremely pleased.

My thermostat konked out on me and I am a wanna be do it yourself-er widow. So I watched you tube video on how to install a new thermostat. Looked pretty straight forward. So I bought this one, best buy, good price, big numbers for my old eyes, simple to program. So I'm all nervous about installing it. Got the power turned off on the furnace/AC at the circuit breaker. Then got the cover off. OMG those wires and screws are tiny!!!
Got all the wires labeled. (Stickers Provided) Took off the old mounting bracket. Installed the new one. (Sheetrock anchors provided too.) Got the tiny tiny wires and the tiny tiny screws (apparently they are all that way) in the right slots. Put in the batteries, programmed it (simple) snapped it on the mounting bracket. Turned on the power and PRAISE THE LORD it works!!! Girls ROCK!!! I was so jazzed. It really was pretty easy to install, I just was so outside my comfort zone. So ladies this is the one for you!!

Forward:This is more than a review and experiences with the Lux Products TX9600TS. It includes what was important to me when looking for a new thermostat, the short list of the others I researched, and why I chose this model. The reason for replacing my previous thermostat, a Honeywell T87 style mercury type thermostat, was because it would run for a short period of time, stop, then restart again. The T87 worked fine with the forced air furnace we had several years ago, but ever since we upgraded to a 93% condensing furnace, it cycled so frequently that register air didn't have time to warm up adequately. We have a standing joke around here. "We have a furnace that heats with cold air."So why do people have rapid, short cycling problems like this after upgrading from say forced air to high-efficiency condensing furnaces in cold climates? My theory is it might stem from the differences in their their sequence of operation.A. Forced Air furnaces, i.e. 80% and less. 1 Thermostat calls for heat. 2. Burner starts. 3. Circulation fan starts after the air from the heat exchanger reaches 120-140 degrees. 4. Heats house. 5. Thermostat stops giving the call for heat. 6. Burner shuts off. 7. Circulation blower continues to circulate air until the air coming out of the heat exchange cools to 85 to 100 degrees so there is never any cold air exiting the register.B. High Efficiency Condensing Furnaces, i.e. 90% plus. 1. Call for heat. 2. Draft motor starts and pulls in cold air from outside. 3. As soon as furnace detects draft, it starts the hot surface igniter. 4. At the 30 second point, the gas valve opens. Flame detector must see flame within 2-3 seconds. 5. Circulation blower turns on, no matter what temperature the heat exchanger is. 6. Heats house. 7. Call for heat from thermostat ceases. 8. Gas valve is turned off. 9. The draft motor continues to pull in wicked cold air through the heat exchanger for the next 30 seconds, while the circulation blower blows air across the now wicked cold heat exchanger. 10. Thermostat senses the cold air, and starts a new cycle with a call for heat 25 seconds after the circulation fan stops from the previous cycle.Establishing my requirements:As our climate changes and we edge closer to the next ice age, winters have been getting colder, and things were getting a little out of hand this winter, so I decided it was time to get a thermostat with some control. There was no requirement for a programmable thermostat, but my requirements were:1. One I can control the temperature between the cut in and cut out time. That means I have to be able to understand HOW it decides to turn on and off so the I can determine if it meets that requirement.2. Doesn't require a degree in computer mysteries to use.3. Doesn't rely on batteries.4. Sensible price, which to me means less than $100. I had some fun looking at the NEST, Ecobee, and Prestige, but they were never contenders..The Short List:My first problem was to determine which products within the price range didn't require a battery for operation. That eliminated all of the digital, non-programmables. I came up with the following list:Honeywell RTH7500D Conventional 7-Day Programmable Thermostat $59.95Honeywell RTH7600D Touchscreen 7-Day Programmable Thermostat (Touch screen version) $79.95Lux Products TX500U Smart Temp Programmable Thermostat 5-2 Programming $37.97Lux Products TX1500U Smart Temp Programmable Thermostat 5-1-1 Programming $39.97Lux Products TX9600TS Touch Screen 7 Day Programmable 7-Day Programming Thermostat $63.67Researching and Reading the Documentation:I studied the manuals, and called and e-mailed both Honeywell and Lux Products. Both were very responsive, English was their first language, and they were knowledgeable.Contacting Lux:I sent LUX an E-Mail one night with several questions about the 3 different models I was looking at. The following morning I received a call. It was a very good conversation. During the conversation I mentioned how I like the ability to adjust the sensitivity on with what they term as swing. He was quick to point out that the TX500U and TX1500U current versions had removed swing. They have an a and b suffix.on them when you open the package, E.G.TX500Ua, TX1500Ua, and a different manual, even though the packaging and marketing still shows TX500U, TX1500U. He said they decided to retain swing on the TX9600TSa. The TX500Ua and TX1500Ua have something called Duration. If you enter 12 minutes, it will not turn on more than 5 times and hour. It heats up to the recommended temperature and stops, and won't start again until after the 12 minutes expires, and only then when heat is required. The temperature span between start and stop temperatures is fixed. Revision "a' was 1.8 degrees, and the "b" revision was further refined to 1.4 degrees. That would mean the true temperature variation could be more than that between cycles if the furnace was prevented from starting. On LUX models with swing, you put in a number between 1 an 9. Each number is 0.25 degrees F, for a maximum of 2.25 degrees, which I thought wasn't much of a range, until I learned swing doesn't work like I thought. Swing works on both sides of the set point so if you you enter a 2, it does turn on when the temperature dips below 0.5 degrees below the set point, but it also doesn't shut off until the temperature reaches .5 degrees above the set point. Thus to 2.25 maximum swing equates to a 4.5 degree spread between start and stop, which should be enough.Contacting Honeywell:Honeywell doesn't have swing except in the Prestige line which is only available through contractors. The DIY (Do-It-Yourself) models have only Cycles Per Hour, however they generally discourage it. I called Honeywell, and after they explained how it worked, I can understand why they discouraged it. For instance, for a high efficiency condensing furnace the recommend setting to 3 cycles per hour. What that setting does is divide an hour into 20 minute periods, and further divide those in half, with a 10 minute window where the system can be on, followed by a 10 minute window when the system cannot be on. Because of my disbelief, I made multiple calls to confirm this. That is actually quite different from the LUX. The LUX could run the entire hour if it had to, to get to the cut off temperature, and then not allowed to start again until the period expires. The Honeywell CPH sounds more like a unintelligent 50% duty cycle enforcer. I can understand now why so many reviews on the Honeywells mention frequent cycling as a problem, and why they encouraged me to go with the $300-$500 Prestige line to get swing. I also mentioned to Honeywell how they didn't have any temperature calibration ability. I was assured that they are set accurately at the factory, and there would be no problem with the temperature being off. However, the only thermometer that I know of that you can trust over time are the mercury and alcohol ones.Decisions, decisions:I leaned toward the Honeywell. I thought it looked nicer. The Honeywell also has daylight savings time built in, but not the LUX, in fact the Lux only uses day of week and time, not the date, which made me think, Micky Mouse. The other thing I liked was that the Honeywells have the option to auto switch between heating and cooling or manual. The feature doesn't matter to me, but it does indicate well thought out. I tried to rationalize that the Honeywell has been making thermostats for well over 100 years, as has Lux, so I shouldn't have to worry about them having a cycling problem like I had then. However, I had trouble coming to terms with that position when one of the major reoccurring complaints about the Honeywell on the web from people in cold climates, is rapid cycling, which is also why I was shopping for a thermostat in the first place. What I needed was something that stays on long enough to heat the house, which means the only cure was is a broader temperature span between on and off. There is only so much you can do to reconfigure the furnace, and I'd already proven furnace tweaking wasn't enough to fix the problem. The sad truth was the Honeywells didn't have a usable work-around for a frequent cycling problem. That left me with the 3 Lux Product's thermostats on my shortlist. There is only $2 difference between the TX500Ua and the TX1500Ua, so I dropped the TX500Ua from the list. The only difference that mattered to me between the TX1500Ua and TX9600TSa was the TX1500Ua uses Duration technology while the TX9600TSa uses Swing. They both have their advantages. With Duration, the temperature span would be 1.8 degrees for the "a" and 1.4 degrees for the "b". Thus, it is a fixed span, unless it has to wait out a Duration period, at which point the temperature range would drop until the appropriate amount of time has passed, and the thermostat would send a call for heat. However, as with the Honeywell, it would make the problem worse. Instead of doing very short cycles back to back, it would short cycle followed by a long wait. With the TX9600TSa, I set the Swing/Temperature Sensitivity, and it would cycle based on temperature, but there would never have to wait for a wait period to expire. Swing was the only method that can fix a problem like this. I didn't like paying an extra $30 for a touch screen that I didn't want, but the others didn't have the capabilities necessary to cure the problem. The Lux TX9600TS also advertises Battery Free Memory storage.Purchasing the thermostatI paid more money and bought locally because the furnace was cycling constantly and I wanted to fix it now. The TX9600TS packaging had no hint of whether it was a TX9600TS or a TX9600TSa. It did have a little -004 in small print after the model on the bottom of the packaging. Once it cut open the packaging, the instructions clearly stated TX9600TSa. The first thing I did was make sure the instructions said it had had Swing, like the Lux representative said, and they did. Then I was curious what the differences were between the TX9600TS and TX9600TSa. After going down their manuals side by side, the ONLY differences I could found were they made the TX9600TSa much easier for people to unsnap from its base, which is a complaint in the reviews. The only other changes a saw were slight differences in explaining the same features. The manual has the same number of pages, with the same items on each page.Initial setup of the thermostat:I read the instructions carefully. I didn't want to mess with the current thermostat during such cold weather, 10 degrees, until I had a plan. You need two AA batteries if you are going to do "arm chair" programming, so I got a couple of their recommended AA batteries. At first, I thought less of the Lux because of its use of dip switches instead of the soft setup the Honeywell uses. However, with the Honeywell setup, you need to deal with codes from the manual. E.G. You enter 0180 for the Heating Fan Control, and enter a 0 for gas or oil heat, or 1 for electric heat. Another nice feature of the Lux is that you can change a dip switch setting that can turn off all of the schedules, and use it like a regular thermostat, which I fully intended to do, but decided to leave it the default and change it later. The TX9600TS also advertises Battery Free Memory storage. Many give you so many seconds to change the battery, which indicates that you need batteries to maintain your settings during a power failure.Installation:The next thing was to check if I had the wiring necessary, and how things were currently wired. It was quicker to shut off the furnace, pull the cover, and check out the thermostat wiring from there than to disturb and have to re-level the current thermostat. I learned that the house had 4-conductor thermostat wire, which meant I was one wire short to be able to run the thermostat off furnace power, instead of the battery power. Fortunately, it didn't appear the wires were secured inside the wall, and unsecured is standard standard I hear. That meant I could use the old cable to pull a new one. I bought 22 feet of 8-conductor thermostat cable locally, and while there, picked up a 97 cent thermometer that read the same most of the others in the rack. I shut off the furnace switch as well as the furnace and air conditioning breakers. I took pictures of the furnace and thermostat wiring connections. It indeed turned out that pulling a new thermostat wire was far simpler than I had feared. Soon I had the new wire connected to the furnace and thermostat base and rechecked. I read where some people were upset because the touch thermostat would slide on the wall, so I put some thin 3M foam double-sided tape on the back of the base, away from the raised mounting areas, positioned the base with a level to make it look good, slid over to the right so the wiring came through on the left end of the thermostat base opening, and pressed the base against the wall. Having it to one side allowed me to mount a little nylon wire holder to the wall so the wire could never fall into the wall by accident, and the thin double-sided tape held the base in position while I drilled the new mounting holes in the wall. Then I pushed some insulation in around the where the wire where it comes through the hole in the wall, and put tape over the hole around the wire to prevent a draft from between floors from influencing the thermostat. Next I snapped the thermostat to the base, turned on both breakers, turned on the furnace, turned the thermostat to heat, and the furnace started. When you touch the display, it lights for 10 seconds, and you can faintly hear an oscillator while it is on. It surprised me that the display was not as bright as I thought it would be. That is probably good since most people probably just run off the batteries, and at night you wouldn't want it very bright. However, I was expecting the cool factor like I saw in the advertising, but what I received was what was practical.Final setup:I was initially confused during the setup only because I had difficulty accepting that it was that simple. I was thinking I must be missing something. Not so. You press the Menu button and press the on-screen scroll button to scroll though the settings. Then it's just the Next, OK, and Exit on-screen buttons. If you don't want to use the programs, but have them available, it's still easy. Simply press the on-screen Hold button. After that it behaves like a manual thermostat, but you still have all of the features such as Filter Monitoring, time, day-of-the-week, etc. that according to the manual you wouldn't have if you change the dip switch to have it act like a manual thermostat. It also does not lose the Hold setting when you change the temperature. If you want it to run the schedule, pressing Hold again releases it to run the schedule, and the display changes from Hold to Program Mode. When I touch the current temperature on screen, and nothing happens other than the screen lights up. If I touch the set temperature on screen, up and down arrows appear to adjust the temperature. The Fan On-Off fan switch is simple mechanical switch and the the Heat-Off-Cool switch are simple mechanical switches on the right side, just like a manual thermostat. This is what I like because in Spring and Fall, everything is turned off. In the summer after it gets hot, we simply switch it to cool and have the thermostat control the temperature, and turn it off when we don't want it to cycle anymore. Likewise in the late fall after things get quite cold, we turn it to heat for the season. However, for people that live in moderate climates where it might be cold at night, and hot during the day, they would prefer the Honeywell, which can be optionally enabled to automatically switch between Heat and Cool. The Honeywell doesn't not seem to have the problem of short cycling in moderate climates. When I spoke to the Lux representative, who is also from Michigan, I talked about how I planned to set the Swing to 8, so I would have 2 degrees up and 2 degrees down. He said he has the same thermostat, and said 4 turned out to be enough, so I set it to 4, and set the temperature at 62. This means it would kick in if it dipped below 61, and shut off as soon as the temperature exceeded 63.Experiences:1. It worked as expected right away.2. No more short cycling issues, but I was also in for some surprises. Even in 20 degree weather, it takes well over an hour to lose 1 degree of house temperature. That means with even the 2 degree span, the heat would be off for more than 2 1/2 hours. I didn't know how slowly the house lost heat until now. The way it was cycling before, it acted like the windows were open. It also makes sense to me now why Lux tightened the temperature hard-wired 1.8 degree temperature span on the TX500Ua and TX1500Ua to 1.4 degrees on the TX500Ub and TX1500Ub. However, it also makes me very glad that I picked the TX9600TS where I can adjust the span anything I need, down to .5 degrees. (A setting of 1 will cause a call for heat at .25 degrees below the set temperature, and cancel the call for heat .25 degrees above the set temperature.)3. My concern about others in the household being able to understand the thermostat if I left it configured for optional program mode turned out to be unfounded. It was a 1 minute class, and not even the least technical had a problem understand what to do.4. Nobody wanted to run a schedule because they wanted to do it manually. Two days later they were talking about a running schedule.5. On the Honeywells, people complain about the loud click when things happen. I found no complaints about the Lux in that regard, so I didn't know one way or the other. I can report that the sound of the click of the internal relays inside the Lux are very faint. You need to be close by to even hear them.6. Both Lux and Honeywell state they are temperature calibrated at the factory, and you should never have to change anything. However, at least the Lux does has a way to do it if necessary as things change over time, instead of replacing the thermostat. The old thermostat and the thermometer I picked up at the store agreed on the temperature. The Lux read between 4 and 5 degrees high. I simply set the calibration to -5.Summary:For me, I don't believe I could have done better than the TX9600TS. I discovered how useful Swing is. If I lived in a moderate climate, I would have no doubt gone with one of the Honeywells. Might one of the two Honeywells worked for me? I can't know that, but from the complaints around the web, reading the documentation, and talking with Honeywell, they don't have anything you can configure to cure the short cycling problem if you encounter it."Well that's my story and I'm sticking to it."

We were able to get $125 in credits so that helped cover a decent chunk of the price for the Nest. We live in an area where the temps don't vary much so I don't know how much money we will save long tern, winter will likely be the true test. So until then I don't know that we are getting the full benefit of a connected thermostat other than the credit from the electric and gas companies. The history shows no usage over the past 10 days so I'd say that's pretty energy efficient!I do really like the design and the notifications when there are energy rushes where we can choose whether or not to participate in reduced energy use for credits to our bill. The thermostat is also nice to look at, which is something I never thought I would say about thermostat. I don't use the app much but again it's pretty cool it can tell you the humidity reading in your house.So yeah, thumbs up on the smart thermostat. If it does anything cool I will have to come back and update this review.

This is a very fun thermostat for the energy conscious homeowner. This thermostat is very easy to install. I did not read the instruction manual but rather went to the nest.com website as it was most helpful. Be careful about where the wires go on the new unit based on the compatibility Diagram generated by nest.com. My emergency wire was incorrectly placed on their diagram. If you have any doubt call their help number for assistance. I found the technician very useful. The thermostat can be programmed from the unit on the wall, the Nest app, or your desktop computer. The nest app is best used, in my opinion, for making minor changes to your settings. If you really want to make serious changes, such as calender settings, it is best to use your desktop. I highly recommend this thermostat. Also, be sure to check with your utility company for any possible rebates.

Very easy to install. I had a 2nd generation Nest at my old house and bought this one for the new home. I ended up using the included wall plate because there was a large hole in the wall from the old thermostat. Eventually I'd like to patch it up because the Nest looks cleaner by itself.My 2nd generation had a little more resistance to turn the dial - this one turns smoother which I like.I wired in single stage heat, single cooling, and a common wire to avoid any battery charging issues. I'll add a whole home humidifier to the * input this winter which I had at my previous house. Nest controls the humidity flawlessly. One thing I would like to see is some type of frost control algorithm - at my old house, when the temp was -20 F in the winter, I'd start to see frost on the windows. Would be nice if the Nest could use the outside temperature to dynamically control the humidity. Or just allow programming the humidistat based on outdoor temp.I turned off the learning schedule feature - my schedule was too erratic for this to be useful, so I just program a 5+2 schedule. Big benefits I see with the Nest is Auto Away and the ability to remotely control the temperature/humidity. Being able to see the usage history is nice as well.Great product.

I admit, my old thermostat was about as low-tech as it gets - just a yellowing plastic box with a single metal bar that required manual sliding left or right to trigger heating or A/C - so it's hard not to like anything that replaced it, but I really do love the Nest thermostat! It does save me money in the long run because previously, I had to slide the old thermostat's little bar to a certain position, and then if I wasn't near the thermostat when I was sufficiently cool or warm, I would just let the heating or A/C continue to run needlessly because I didn't want to go all the way upstairs and slide the little metal bar again. Now, I just make a couple of taps in the app and voila, instant adjustment! There are also a host of other neat features that I don't personally use (auto-learning, home/away geofencing, schedules) but that I can imagine would be tremendously useful for others. Installation did hit a small snag when the A/C would only stay on for a few minutes and then turn off; the technician was baffled. But he made a quick call to Nest Support and the representative was super friendly and helpful, and was able to walk us through some troubleshooting that ultimate determined that I needed to have a common wire (C wire) installed, which took only another 20 minutes to install, and I was back in business and have had no problems since then. I'm very pleased!

I moved into an apartment a month ago and one of the first things I wanted to do was replace the thermostat - which was the typical old-timey circular one which has never been accurate anywhere I've lived. I don't pay for gas at my place, but the A/C is electric and I knew that cooling was going to cost me in the summer - I have about 20 feet of floor-to-ceiling windows facing the sun half of the day. After doing some reading and comparing to other smart themostats, I found this one to have the best app, features, and price for me.I won't know how much it'll actually save me since I haven't spent a summer here yet but I can imagine the Away feature alone makes it worth it. Yeah, I can just go and physically turn the cooling off or something whenever I leave the house, but being able to have it on a schedule or automatically turn off when it senses me out of the house is worth the cost of having it be done automatically.So with next to no electrical knowledge and a screwdriver, I managed to get it set up in less than an hour. It's so easy that I'm inclined to say that unless you have a physical disability preventing you from doing it yourself, it's a waste of money to pay someone to do it.There's already been a few updates since I first installed in (including a recent update to make better use of the "Away" feature), and I can't say I've had any issues or bugs yet. It deals well with the sunlight hitting it and doesn't over-heat the place from thinking it's warmer than it is. Best of all, ComEd had no problem giving me a nice rebate to cut down the cost of the device to nearly half - it was a no-brainer, basically.

I really struggled on which smart thermostat I would get - the ecobee, the Honeywell, or the Nest. Ultimately, the Nest won out due to aesthetics but the concerns I had from the negative reviewers here kind of haunted me.I was able to install this myself in MAYBE 5 minutes. My 5 wires were C, G, Y, W, and R so I wasn't sure exactly where to connect them to the Nest. I did a quick google search and came to Nest's support where you click on what wires you do have and it tells you exactly how to connect them to the Nest. That was a neat feature.I did have one issue with connectivity but it was trying to connect via wifi to my Apple Airport (from 2007), The nest said it was connected to my network, and it was, but it couldn't get past firewalls or something. Anyway, I just disconnected my Apple Airport and had the Nest connect straight to my wifi router and it worked like a charm. I've had similar issues with other things trying to connect to the Airport so I knew that it wasn't the Nest itself.Last thing - I was hoping that I could install the Nest just bare against the wall, but I couldn't. There were still holes outside the Nest. If I had to complain about anything it would be that the trim plate included isn't quite as nice as what I think they should include. For this price, I feel like even a rounded piece of sheet metal that would compliment the sleekness of the Nest should be included. I bought a metal back plate from Amazon for $25 but it's bigger than what I needed and kind of takes away from the aesthetics.The Nest has been up a week in my house and has functioned exactly as expected. Two days after me setting the thermostat to my wake up temperature and going to bed temperature and it did it automatically. So cool!OH! And I almost forgot to mention...they include a cute, higher quality screwdriver to disconnect everything from your old system and connect it to your new system. This was an absolute unexpected delight to find and I wanted to mention it

Been very pleased thus far. No issues with displayed temp not matching ambient temp - and I am using the 24v dc wire from the heat pump to power the unit, with batteries as backup. I've read several instances where people have had an issue with the 24v dc connector causing their thermostat to 'run warmer' than the room really is. What I can say is that we have noticed a huge difference in how our heat pump performs. It seems to run much more efficiently - it runs more frequently but much shorter cycles and the house is much more constant, temperature-wise. I would have given the thermostat 5 stars, except I had to drive quite a way to buy a 1-foot length of thermostat wire to put in a jumper to make the heat work correctly (after a call to tech support). If you do NOT jumper the W1 terminal from yellow with a heat pump with emergency and aux heat, you will only get heat if you run the thermostat up to the point where it calls for aux heat. The old thermostat did not have this jumper in place. Regardless, I think they should provide a jumper wire - not everyone has a piece of thermostat wire just laying around. Other than that, I am completely pleased with the performance, especially for the price of this unit.

I chose this digital thermostat because of it's larger digits. I don't need a programmable model but it's easy to set this to SETHOLD so it does not revert to automatic setback if you know how. The booklet is clear and they do have U.S. phone support. I have 2 and like the clean design. It's a 2 piece design so you can snap off the thermostat from the wall plate. The only disappointment for me is there is no provision I can find to set the backlight always on. It's located in a dark hallway and requires me to push the button to read the display. I do have power provided by the furnace controller but I think the battery inside may power the backlight. I suspect but am not sure that if the battery were to become exhausted the thermostat might just revert to it's preset values. This would definitely not be good for my needs and I must thus watch the battery indicator for this. Maybe I can confirm this one way or the other with their phone support. Then again maybe I should just remove the battery and see what happens.

Pretty easy to set up. Set one day, can copy/paste to others. Kind of a pain to cycle through all days/times/settings to adjust weekend days, but in reality shouldn't be doing this very often. Took one star away because the ambient temperature was about 2 degrees F off. Had to adjust it. One other small complaint. If you want to temporarily change the setting away from what's programmed, there are two buttons available after adjusting: "Next" and "Hold". If you (or someone in your household, lol) accidentally pushes "Hold", it holds that temperature setting indefinitely, ignoring all programming... Make sure to use "Next" if you want next programmed setting to kick in when it's time. For the price, I'm happy with my purchase.

So far this product works great. I installed it myself with little problems. If I have on peeve or two it's the instructions. There are 6 choices they give you depending on your unit. If you're like me, I just know it's a gas furnace.The help line only open Monday -Friday 9-5. So if you do it on the weekend like most of us, you are SOL.If you purchase it from Home Depot, don't ask tbem. All of them are clueless and nothing like their commercials.But besides that..nice unit.

I purchased this because the Honeywell that came with my new house was not programmable. Installation was very easy since the letter scheme on the old Honeywell matched the Lux. The new thermostat looks very cool and modern in my house since it is basically just a big touchscreen. For some reason I was expecting the cool blue backlight to be on all the time but it isn't and I guess that is probably good since it would drain the batteries pretty quick, it only lights up when you touch the panel. The touch screen is very nice and I had no problem using it to program the thermostat. My local Lowes carried this TX9600TS model as well but it was almost $20 more than on Amazon. I'm very happy so far and I would recommend it to others.

I recently installed this in my apartment, as what i had before was solely a temperature gauge.The thermostat it replaced was a heat pump system(the most wires)I was constantly adjusting the thermostat when I woke up, when i left for work, when i came home, and when I went to bed.I bough this has a permanent addition to the apartment, and being permanent i did not want to go with the app enabled devices that were more expensive.This thermostat met all my expectations. it has a 4 time 7 day programmable setting with an adjustable offset. The offset prevents the A/C from toggling repeatedly, which helps keeps the electric bill lower.It was easy to install and took me around 45 minutes in total.The only downside is that it is a bit time consuming to setup the different time and day temperatures, and the system is unforgiving if you make a mistake with the settings. This is a small downside, as I do not constantly change the settings, but still something to consider.

Easy to install by sending a picture of current wiring to the company and getting a picture of how to wire. Love that I can control with my phone while in another room or away from the house. The learning part of it can be a little annoying because it makes assumptions sometimes off of one day's history. For example, I woke up the other night freezing because it turned my thermostat down 3 degrees because it made it a schedule to do that every night even though I only had done it one night before. However, I would recommend and expect it to learn more as I use it more often. I have only had it for about 3 months.

I was initially impressed with my nest. The more time I spent exploring it, I found nice capabilities. Then problems started after two months. My home is in the colder climate of northern Michigan. While in Florida I checked my nest status. The nest was not calling for heat and temperature was dropping fast. I called the nest techs which were polite and helpful. They said my nest was wired for a heat pump which I do not have. Just impossible. The nest was actually calling my ac to cool down the house. Luckily I got a heating contractor to resolve it that was very familiar with nest. The nest was properly wired, but when wiring was check via the wi if it said it was erroneously wired for a heat pump. The nest was removed and reset. Now functions properly. The tech said they have never seen this malfunction before, but it's noted in their website. I asked for a replacement which they promptly sent. I'm now requesting reimbursement for my very expensive contractor services. This will be a good test if they stand behind their products. We will see.A month later Nest did reimburse me for the furnace tech visit. They have integrity. Nice to see today.

I bought the open box, the down side to this was no instructions or screws, easily solved for the most part. I did find the nest website was hard to navigate for help. the set up instructions are simple but because it was open box it recommended calling the 800 number for help resetting it. The tech support was fast and friendly, but if the website was easier I could have done it all myself. All they did was tell me to charge it and do a system reset which wasn't all that hard. The set up is simple as long as you charge it, I could not find any information on needing a charge or how long a charge lasts.The positive is it's easily programmable, and easy to use on your phone. Very simple to turn the heat up and down, and the unit feels very solid. Good buy, much better than an old digital thermostat. You can turn the heat up and down without connecting to the internet,

Nest third generation purchased from Amazon reseller. The box showed evidence of a label removed. Shrink wrap meticulously razor trimmed around removed label and damaged box area painted white. Not sure what to make of that but the product was not damaged and worked fine.Just what you would expect. Simular to an iPhone, everything just worked. The free app is simple and functional. Scheduling is fast drag and drop. Love the connection to my iPhone location. My old programmable was basically a set temperature and press hold device. Programming was too difficult to constantly change to my irregular schedule.Not sure if it will find me close to home and adjust temp automatically. We will find out. Price $218 + tax-free shipping. $100 ComEd rebate. Four stars because packing was fondled without disclosure.At the end of the day I hope to recoup $118 over the next year's heating cost. I use propane heat and pay about $2000/ year. If it saves 6% there is my justification. I will probably never audit the savings and just assume happened. I will settle for just coming home to a temperature adjusted house.As a traveling empty nesters we like that we have access to our home temperature from remote and that it will alert if something is wrong. My furnace went out twice last winter 2016 with my old controller (igniter then exhaust blower). I was home both times. No alerts, just a cold house. That feature alone is worth the price of admission.

I like nest's so much, I upgraded from the first generation to the third generation, mostly to get farsight, since my nest is mounted in a weird place, and being able to activate it from several feet away is useful. It's still a great thermostat, and works in concert with my nest protects.The only things keeping me from giving it five stars is a lack of an additional temperature sensor, and a lack of a graceful upgrade process. Basically, one has to reinput everything after a new install.

The Nest has been a lifesaver for us! I can program it to start heating up the apartment 30 minutes before I wake up so I'm not shivering the moment I step out of bed, turn off when I leave for work, turn back on when I'm on my way home...well, you get the drill now. The best part is that I can control all this on my iPhone app, which is so incredibly convenient even for when I'm just in a different room and feeling lazy :P.However, there are a couple of things I would change:1) Our old thermostat was hooked up to a high voltage system, so we actually had to use a relay between the Nest and the wiring to make the voltage conversion happen. I know that Nest sells European versions that natively work on high voltage systems. It would be very useful if this version of the product were made available for American consumers as well, since I know I'm not the only one who's had to do this to get the Nest to work in their home!2) Show me the current temperature, not the target temperature! Reading other reviews here has proven that I'm not the only one with this gripe.

The unit is very good and has been in service almost 1.5 years. We do not program, but could.Anyway, I am not thrilled about the switches on the side. Very hard to operate between positions. All controls could have been digital.

Not so easy to program as it sounds. Tip: put the battery in, program it, then plug it into the wall: sitting down under a good light helps

my wall didnt have a wire for power so i ad to use the battery, the unit buzzes when the blue back light comes on, its really loud and the back light never stays on, so you cant see the temperature in the room. although i think its a great unit/value for the price, it could be better in functionality and ease of use.

The Lux TX9600TS offers some advanced features at a reasonable price. It’s capable of performing well, but there’s one critical caveat.The thermostat can be powered by:- Batteries alone (2 AA alkaline batteries)- 24 volts AC alone- 24 volts AC with battery backupIf your thermostat cable has a 24 volt AC common wire, it can be connected to the thermostat's “C” terminal to provide the power. This can be used alone or in addition to installing batteries as a backup. According to the manufacturer, the thermostat has non-volatile memory for the program, but you will have to reenter the current time and day if the thermostat has no power source for more than one minute. For convenience, the thermostat can be programmed while removed from the wall if batteries are installed.I tested the Lux TX9600TS with my heat pump over a three week period in heating season and made the following observations.When powered by batteries alone the thermostat performed well –– accurately displaying and controlling room temperature. In Heat mode with the thermostat’s swing setting at +/-0.25°F the room temperature differential measured by a min/max thermometer 6” from the thermostat was no greater than 0.7°F.After connecting AC power to the “C” terminal, the temperature displayed by the thermostat suddenly decreased 2°F, then slowly increased 5°F (a net increase of 3°F) as if the temperature sensor was being heated by the power supply. Adjusting the thermostat’s calibration improved the accuracy of the displayed temperature, but the magnitude of the error fluctuated over time.In Heat mode with AC power, noticeable temperature swings and prolonged cycle durations occurred even though the thermostat’s temperature swing was set at its minimum of +/-0.25°F. The room temperature differential was high as 2.4°F measured by a min/max thermometer 6” from the thermostat.After disconnecting AC power from the “C” terminal, the temperature displayed by the thermostat suddenly increased 2°F, then slowly decreased 5°F (a net decrease of 3°F) as if the temperature sensor cooled until it reached ambient temperature. At this point the thermostat accurately displayed the ambient temperature at the default calibration of 0°F and provided good temperature control.The disadvantage of powering the thermostat by batteries alone is that you must remember to replace the batteries when they get weak, and make sure to have fresh batteries on hand.As a result of the poor performance of the Lux TX9600TS when powered by AC, I purchased a Honeywell RCT8200A (identical to the Honeywell RTH8500D), and began comparison testing.Although the Honeywell lacks some the features of the Lux, including adjustable swing, adjustable offset and energy usage monitor, it performed very well when powered by AC –– accurately displaying and controlling the ambient temperature. The room temperature differential measured by a min/max thermometer 6” from the thermostat was no greater than 0.7°F, matching the Lux’s battery-powered performance.Both the Lux TX9600TS and the Honeywell RCT8200A / RTH8500D have an optional recovery feature. With recovery enabled, the thermostat attempts to reach the desired temperature at the scheduled time by changing the temperature setting early.The recovery feature isn’t just for comfort. A thermostat with a good recovery algorithm can save energy with systems that have a second heating stage that’s more expensive to operate than the first stage (for example, a heat pump with electric resistance auxiliary heat). During recovery, the thermostat gradually increases the temperature, maximizing use of the more efficient first heating stage, and minimizing use of the second stage. If you have such a system, you can save money by using the recovery feature even if you don’t need it for comfort.The recovery performance of the Lux and Honeywell models I tested is somewhat limited because they are not capable of monitoring the outside temperature and adjusting the recovery accordingly. That capability isn’t expected at this price level. These thermostats estimate the recovery time based on previous performance.I don’t have the capability of measuring the energy use of my heating system while controlled by each thermostat under identical conditions, but I did observe the recovery durations. I allowed each thermostat to “learn” how long it took my system (a heat pump with electric resistance auxiliary heat) to reach the programmed temperature setting for several nights. The Lux TX9600TS began recovery no more than one hour early. The Honeywell RCT8200A / RTH8500D began recovery as long as three hours early in order to minimize use of expensive auxiliary heat.Comparing the displays of the two thermostat, the Lux has larger characters, but the Honeywell’s light green backlight appears brighter and provides better contrast than the Lux’s blue backlight. Both thermostats turn off their backlights seconds after touching the screen. This annoying behavior is understandable if the thermostat is operating on batteries, but I’d prefer the backlight stay on at least one minute when powered by 24 Volts AC.If you want a thermostat with adjustable swing temperature and adjustable temperature offset between the first and second heat stages, the Lux TX9600TS is worth considering, but only if you are willing to power it with batteries alone.I would rate the Lux TX9600TS as follows, contingent upon its power source:4 out of 5 stars if powered by batteries alone.1 out of 5 stars if powered by 24 Volts AC.

I like the thermostat. I have issues with it though. About 4 times a year the unit "freezes" up. The thermostat acknowledges that the actual temperature but it never turns the ac or heat actually off. When this happens I usually wake up in the middle of the night with my house at about 60 degrees and turn the thermostat to OFF. I let it sit like that for a while and turn it back on a couple hours later and it usually performs fine from there. I am not sure why mine does this and reading other people's comments it does not seem like anyone else has issues with this. I never had any issues with my old thermostat and it does not happen often but I worry about it when I go out of town. Good unit otherwise

The thermostat looks great, is easy to install, and has a lot of features. However when the back lite is on, it makes a high audible buzz noise. I knew going into it this may be an issue, and when I tried to show my roommate how to use it, first thing he said after the screen lit up "whats that buzzing sound?." You will hear it and it only buzzes when you touch the screen and the back lite goes on. For sixty something it is a value compared to what's out there, as long as you are okay with the buzzing it will make.Second thing I want to point out, the model I got from Amazon was the TX9600TSa.... The "a" is the newer model.

I give this 3 stars because the first one I received was defective. I paid my HVAC company $73 to come out for the install, and it wouldn't work. The wires were pulling the electrical amps required, but no luck. The customer service rep I called, after debating with me and my installer for 20 minutes, finally said they would send a replacement. Another $73 to my installer and the second one worked. I'm going to contact the company and try to get my 1st installation fee refunded, since the product was defective. This was quite frustrating. My installer hasn't had good luck with the Nest thermostat, so time will tell how long this lasts. There are other brands of thermostats with much better warranties. Think twice before you buy. If you have the skill set to change it out yourself, then you are ahead of the game.

Installation is not bad, setup involves a lot of steps, and it keeps wanting to dial back the temperature settings. I find that I have to keep checking to make sure it hasn't decided to only cool to 77 instead of the 74 I told it to. I suppose it will learn and adjust eventually, but it has been several weeks now and it keeps wanting to change settings while I'm asleep.It also only has one sensor (like most conventional units) so I have to guess what to set it to in order to make sure that my office (south facing, second floor) gets enough air conditioning. If I had this to do again, I might have been better off with something that uses multiple sensors.The software interface on my phone is easy enough to use, but not great.

I have had this thermostat installed for two days. The ambient temperature fluctuates in error from one to three degrees higher than the actual inside temperature. It is normally two degrees off with the error fluctuating from one to three degrees. I never had even a cheap thermostat do this. I am feeling sorry that I bought this brand. I thought I was getting the best qualitity but obviously not!

To be honest the novelty of it wears off quickly and it becomes just another thermostat but I like the remote control and the easy setup.I wish I could have purchased 2 but at this price point it's not worth it and the app makes it accessible on your smartphone so it's handy to change the temps as necessaryNot sure if I'm saving any money with it but I'm sure it's better than the 20 year old unit I had before.Good replacement for an older thermostat but not worth it if yours is less than 10 years old and you really want remote.control and are away from home frequently during the day at odd intervals

The manufacturer created the installation instructions for a complete novice which is great as long as this thermostat is replacing a thermostat with the exact same wiring (and labeled the same). I spent significant time on line figure out how to wire this to my system because the information provided with the thermostat was really minimal. I am happy now that I have it working; however, I nearly sent it back due to the installation frustration.

I put Nest thermostats in the upstairs and downstairs of my home in NC this past winter. I was very pleased with the level of customer service provided by Nest, as I was able to take a picture of my current wiring and the customer service team created a custom diagram that showed exactly how to install the new thermostat.I love the wireless capabilities and the cell phone app that allows immediate adjustment from any location.The jury is still out on utility savings. One month my home was ranked as one of the most efficient in its class and another month (using the same heating patterns) it was ranked less than the most efficient. I will give three stars until I see a better ROI and may update at that time.

Very complicated install and directions in comparison to store bought

I liked the product fine while it worked. Just over two years (25 months to be exact) after I installed it, the temperature wouldn't go above 61 degree with the thermostat set at 70. This went on for over a week. I thought something was wrong with the furnace, so I called the repair guys (not cheap for me because I live very far out in the country and the repair guys have to drive over 30 miles to get to me). Anyway, they looked it over and said the furnace was operating fine. On a whim I turned the thermostat to 80 and the temperature came up to 70. A thermostat of this quality should last much longer than two years.

Easy to install however the room temperature appeared to be at least 3 degrees higher that it actually was. I compared it 2 thermometers that I placed in the same area as the Lux unit. I know are very accurate. Don't waste your money. I decided to return it for refund. I later ordered an Emerson unit. Much more accurate and more user friendly and less money.

I gave this device several months of trial. However, it has proven to be almost impossible to program and certainly impossible to see in normal lighting conditions. Even the backlit surface which only lights when you touch the screen has very little contrast between the so-called numbers and letters and the background.In programming you have about 4 to 6 seconds to enter your data to program the machine. Then the light goes out and you can go longer see it. It proved it proved impossible for me to program properly and certainly to check my data out. I have not returned it, but I have purchased a replacement.

The thermostat looks nice but unfortunately has flaws. When powered from the AC when back light is on it emits annoying high frequency pitch. I would have accept that but the thermostat was failing to maintain temperature within the programmed range. The shift was up to 2 degrees. I had an older and cheaper RITE TEMP that was working better and which I put back in place.

The thermostat "works" in the sense that it reliably turns the furnace on when the temp is a few degrees below the set temperature, and turns it off again when the temperature is a few degrees above the set temperature.However, the temperature sensor is inaccurate and unreliable. The thermostat routinely displays the current temperature as 3 or 4 degrees warmer than the actual temperature (as verified by independent measurement). That forced me to redo my heating program and set higher values for all of the temperatures. This took about 5 minutes, which is not a huge deal, but it was something I've never had to deal with on any other thermostat.More importantly, the device emits a high-pitched whine whenever you activate the touch screen. The noise isn't terribly loud, and it goes away as soon as the screen shuts off again, otherwise I would have returned it already.Given the bugs, I fully expect this device to fail soon. When it does, I will not be replacing it with another from this manufacturer.

So here is a 5 star product with 1 star customer support system (hence the 2). Easy to install, amazing tech, GREAT design. When I went to install mine, though the install went perfectly (and really simple), and I looked up to make sure my wiring was compatible (it was, per Nest's site), the batteries immediately drained on both devices (I bought two). Spent an hour with Level 1 support (who was very nice and supportive) with no AC on a 103 deg day, then was referred to Level 2, who was a total *&$#. Got on the phone and said, "Sorry, it just doesn't work with some systems." No effort to determine what else might be wrong, could be tried, etc. I asked why they sent me to Level 2 if there would be no support provided there and his answer was essentially, "I don't know, I just work here." I was stunned - I'd never seen customer service that bad provided anywhere, let alone a company like Nest. Refusing to give up, I called a local HVAC support vendor the next day and was told, "Oh yeah, this is super common with those. You just need to have a common wire pulled or just hooked up." Guy came out and solved the problem instantly (in fact, the common wire was already there and just needed to be connected differently than standard). I had to spend $300 on a visit to check and reinstall the units, which now work perfectly.We all know that if, this is "super-common," somebody in Nest customer support (especially Level 2) should have been completely familiar with the conditions I was describing (as they instantly were at the HVAC vendor) and prepared to advise me to just contact a vendor and solve it with the common wire, but there was no such help provided - just "you're out of luck." How many Nests have been unnecessarily returned to them because of that customer support?So I'm a huge fan of the product -- just be aware that you might encounter less-than-stellar customer support if you have issues. Be prepared to investigate further if the answer doesn't get you where you need to go.

After using this product for almost a year I have found it to be a complete waste of money. It worked ok last winter on heat but when I changed over to AC this summer it has required constant attention and numerous resets and clearing memory. The worst thing is that it can be over set temp by as much as 5 degrees before it comes on. WiFi control and Alexa control work fine. The smart learning feature is just so-so. I still have a warranty on it but I won't bother trying to see if Nest support can do anything as I am not happy with it at all.

They're just ok. After 1 year I had to replace one. It caused my furnace to "sutter" when trying to click on. Everything seemed fine with the Nest, but I switched it with another and there were no furnace issues.While it's supposedly covered under warranty, how long do I have to wait for a new one? Probably too long, so I bought another. A $250 expense.If I hadn't bought 2 of them, I would've gone with another Smart Thermostat brand.The "auto learn" setting is annoying as heck. It never finds the proper temperature you really want automatically. Because of the dining room location of one of my thermostat, it'll put on "auto away" and temps with rise (not enough traffic in there to detect people).The wifi connection is the best part. There's really no other benefit to these.

I'm evaluated this product for a vacation rental I own and it fell short. I wanted to provide guests with an easy to use thermostat that had some temperature limits I could control. Unfortunately when you lock the thermostat in heat/cool mode, then the guest can't control the temperature at all. The thermostat just maintains the range I set. In just heat mode or just cool mode, then the guest can control the temperature within the limit, but I need heat/cool mode since nights are cold and days are hot.For a home (not vacation rental) the thermostat is decent. Nest is good looking and has gorgeous screen, but in the age of touch screens I would find it much easier to use if I could touch the screen rather than use the dial.

I've had this hooked up for roughly 10 weeks. The unit suddenly went offline and showed "low battery". I've had an open ticket with Nest for three days. They are investigating and confirming with engineering. The unit still works like a regular thermostat, once we disconnected it from the internet. Apparently there is an issue with the wifi card, causing the battery to drain and fail.I've been trying to get this resolved for 72 hours. Nest is now going to call me back tomorrow. I would like to give a better review and get this resolved. At this point I am unimpressed with this not being resolved since this is obviously an issue with the Nest unit.

The Nest thermostat was a miss for me.This thermostat displays the target temperature of the room in big bold text. This is quite obnoxious when the heat is off. I live in a region of the country where AC is not a must, so during the summer months my furnace is off and just my fan is running. During these months, my thermostat serves as a thermometer to tell me when to open a window, turn on a fan, or turn on the portable AC. With the Nest thermostat, it merely reads 'OFF' if the unit is off and the fan is running. No temperature, just 'OFF.'I didn't realize how important it was for me to have the actual temperature of the room displayed on the thermostat. I read all the previous reviews on here complaining about the same, but thought nothing of it. A few of these reviews even have responses from Nest saying that it's what THEY thought was the most important number. Does it really matter what THEY thought if a large portion of your customers think otherwise?Nevertheless, I have returned the thermostat and replaced it with a Ecobee3 HomeKit enabled multi sensor thermostat. It's pretty sweet. In my opinion, it looks better, it works better, doesn't feel as cheap, most importantly it displays the correct temperature even when the heat is off.Also, Nest added a feature where you can change the equivalent of the 'screensaver' to read out the actual temperature, but this still doesn't work for those of us who don't always have the unit on.

This Thermostat produces a very annoying low pitch noise any time the back display lights up. First I thought my unit was defective, so I ordered another one. Same thing. Brand new out of the box issues. So if you are sensitive to hearing I wouldn't recommend it.

I connected this thermostat exactly as the instructions said.I set the temperature to 71°F and set the set point to 80°F. I flipped it to HEAT and the fan came on right away but no heat came on.I reset the set point to 45°F and flipped it to HEAT again and the fan came on right away and didn't go off.I reconnected the old thermostat and it worked just the way it is supposed to.

didn't work after two months.......

Doesn't even look remotely as bright as you make it look here?........first one failed haven't even tried the replacement. The first one cost me $202 just to have my old one put back in.because of a defect in the first one!

So poorly made that one of the screws you need to loosen to insert the wires is too tight to loosen (even with two people and vice grips!). Even their own instructions tell you not to tighten it too much. Pathetic.

This thing is garbage. Easy enough to install and set up but will not hold temperature. I set unit to 69 and it will drop all the way to 65 and run secondary heater. Switches won't relay to turn fan on. I tried calling customer service/tech support at 4pm and left my phone plugged in was on hold for 2 hours until they eventually disconnected me at their closing time 6pm. This thing is junk.

works only intermittently e73 error codes . Expert Hvac installer an nest could not fix problems. Avoid!!!!!! 1 star because it deserves zero

one star because the item i received had a chip along the outer ring (white). Returning and will try ordering a new one.

What a disappointment. I finally realized the thermostat wasn't working for me because it was placed in my bedroom wing in the hall . . . second mistake (first was buying the hype). So, i learned how to program it manually. It still does not turn on at the set time unless I walk down the hall and stare at it so it realizes I am actually home at the time I programmed it to come on. When I retreat to my bedroom where it doesn't see me, it apparently reverts to its "she is not home" mode. I am sure from other reviews that this would perform well in a more active household, but for me it doesn't hold a candle to my two other thermostats which I have set to specific times and which go on and off as I have directed them. And, yes, it was set to manual programming before I did the manual setting.

Heartbreaking...spent hours just to install, troubleshoot, and find out we got a dud!

The item I received did not have all of the parts required to install. The mounting bracket with wiring was not included as indicated in the packing information. I had to return it and have not reordered.

My Nest is set to 73 deg, and the AC is not on. I had to buy another thermometer to get the actual temp of the house because there the nest doesn't give you the room temp. Mine says cool to 73, but it lies. Like I said, it is 85 inside and over 100 outside. I can drop the temp to 65 and the AC will turn on, but I really want the temp to be around 78. This thing is not learning a damn thing and it's pissing me off.
