Side by Side Comparison of: Honeywell

I love this controller so much, thanks to honeywell！ Seriously, unless you are looking for the futuristic look, why spend $300 to buy a nest? My home has two AC system, and I have replaced both thermostat with this guy! Here is why I like it:1) Super friendly to people who travel. App is easy to use and interface is very intuitive. You never have to worry that your home gets too hard/cold, or your utility bill exploded in extreme weather2) For landlords, you can control home temperature without having your tenant fudging with the temperatures while you are away3) You can set temperature schedule to make home environment more comfortable.Note: You do need to muddle through the installation process. We ended up tweaking a bit on my AC's circuit board a bit.... But overall it's well worth the investment!

This is my 2nd purchase of this wi-fi thermostat and I'm very pleased with the results so far. The first one was purchased about 2 years ago and was the typical $99 but the one installed today only set me back $79 BUT I was surprised that for the first time in probably 15 years of using Amazon, I was charged sales tax. That ride was bound to come to a stop sooner or later. Oh well, still can't beat the great prices and free shipping on most items and I'll continue to use Amazon as much as possible.Anyway, the reason you're reading this is to gain some clue as to what/how to get that dreaded "C" wire that is required to operate this device in wi-fi mode. I realize all systems/set ups are different but in my case, I did have at least 1 or 2 spare wires on the existing thermostat wire and was ultimately able to connect that extra wire to a 24V continuous connection within the air handler or heating unit, if you prefer. I'll admit, the one I installed a couple years ago was a real test of my wits and my will. Conservatively, if I count the time researching the internet and climbing in and out a dozen times to where the gas furnace resides, it took me about 4-5 hours...I know, ouch, but I've found the convenience of adjusting the thermostat from anywhere in the world to be well worth it, hence the 2nd purchase for our downstairs unit that was installed today. Redemption was had when I met the mailman today and had my new unit mounted, wired and working in about 30-35 minutes, start to finish! What was my secret? The set up was very closely matched to the work I did a couple years ago and with just a little luck on my side, I connected the extra C wire to the correct wire nut right off the bat. This unit is an old school hydronic system (uses hot water to provide the heat for the house) matched to a conventional AC condensing outdoor unit so I wasn't so sure but again, all systems go in about 30 minutes.In a nutshell, you have to connect that C wire, assuming you have a spare wire already in your thermo wire, to 24v continuous electrical supply in order to power and run this thermostat. I'm sure electricians and AC guys may find this amusing and could do something like this blindfolded but for a commoner (there's that C reference again), this was a major score to get this one running quickly. Love it!

For $84 and free 2 day shipping, this is the best WiFi thermostat for the price. I looked at all the expensive options, but I eventually chose this based on simplicity and the fact that you can do pretty much everything from the thermostat itself. I had a honeywell thermostat that looked exactly the same, except this one has one extra button. That one only gave me the ability for weekend and weekday schedule. With this thermostat, I can have a different program for each day. Just that alone is a major upgrade.The WiFi capabilities are much more than what I could ask for. Only gripe I have about the WiFi is that it is not dual band and only works with 2.4ghz networks. The app is simple to use and offers a few more benefits than using the thermostat on the wall. With the app, you can group days you want to have the same schedule and set them all at once. You can also set a hold for a specified amount of time. If you change the temperature it will say hold until your next set point. Then you can change that time to whatever you want. Then at the end of the hold it will automatically return to the schedule. It also works with Alexa once you have enabled the Honeywell Skill.Here are things that I don't like, but are not enough to take a star away.-There is no battery backup and it requires a C Wire. But since it's on WiFi, it will automatically set itself if you disconnect or if there is a power outage.-There are no reminders to tell you that you need to change your filter.-If you manually change the temperature, it will show "hold until XX:XX" on the screen instead of the actual time. They could have programmed it to also show the current time at the top corner or something.All in all, it is a GREAT thermostat. The WiFi capabilities are nice, and if you forget about the WiFi or the WiFi stops working, it's still a GREAT thermostat. If you don't need all the fancy features of the nest or ecobee, then this is the thermostat for you. I just want to be able to change my temperature if my schedule randomly changes, and this allows me to do that. I am more than satisfied.

I have had my WiFi thermostat online now for about two weeks. I am amazed. The setup was simple. The app for my phone is very easy to access and use. I live in South Dakota where it gets very cold in the winter - it is 2 below actual as I write this - and very hot in the summer 112 last July. We travel a bit and it is such a relief to put the system on permanent hold while we are away and as we return home kick the system back on and have a comfortable house to come home to. I am traveling 230 miles to home in the morning, when I am about an hour out I will release the hold and by the time I get home, the house will be right at 70 degrees. It is currently holding at 48 degrees.Of course I have not had the system long and if it fails or begins acting goofy, I will update this review. As of now, I would give it 6 stars if I could.DakotaHoneywell RTH6580WF Wi-Fi 7-Day Programmable Thermostat

I absolutely love this brand and this model of Wi-Fi thermostat. I have purchased 5 of this exact model off of Amazon and absolutely cannot be more pleased with the product, the price and how it functions. Number one the price for a Wi-Fi thermostat is normally much higher. I purchased these for around $85 and yes that should be a concern when most Wi-Fi thermostats are twice that. I think the biggest difference is that this model does not have a fancy screen with all kinds of colors and digital eye pleasing features. However not knowing in advance I thought this would be a problem. It is not because with Wi-Fi thermostats you will never stand in front of that thermostat again. Once you install it you will use your iPhone or other wireless device almost 100% of the time to program and adjust the temperature. I have several businesses with these Wi-Fi thermostats and one in my home. It is one simple app on my iPhone that I open and can quickly monitor, adjust and if needed make program changes to the thermostats. The functionality is wonderful, the ability to program and making temperature changes is so easy. I will definitely buy this again when needed and I highly recommend the Honeywell because number one the price is some competitive and number to the functionality is amazing. I did purchase a different brand and the install and functionality was much more complicated and just not worth the fun of having a different brand. So when needed I went back to the Honeywell.

This may not do as much as a nest, but it does what matters. It is a programmable thermostat that you can control remotely.As everyone says this requires a c wire. Mine did not have the wire and the existing wire was old and wearing out. Great thing is that the wire for my furnace is a simple run and replacing it was quick and easy. I do have some hobbyist experience with low voltage wiring so I was able to hook the new furnace wire up easily. Of course all situations will probably be different. I understand there is a workaround if you do not have a c wire, there is a drawback but it was not a major one. I do not remember the drawback.After it was installed all I needed was a smart phone or tablet to connect the thermostat to my WiFi. There was an update where the thermostat had to reboot but that is to be expected and welcomed with things like these. During the reboot the furnace unit shut off but only for a minute.TL;DR great WiFi thermostat, just check that you have a c wire on your existing thermostat or feel comfortable with wiring for a fix or workaround.

Now that I've used this through all seasons, I feel I should pass on my opinions (updated further down). First, I'm happy with this. The backlight is good, as my unit mounts in a dim hallway. Controls are fairly straight-forward, and the digits are big enough to read without glasses. But I recently discovered a mild issue, which took some figuring out. When I installed this in the summer, I set the internal switch (on the back of the unit) to "gas/oil," since I have a gas furnace. But then my central a/c wouldn't come on. I came back here, read some questions and answers, and realized I needed to set that switch to "electric." Then my a/c ran fine. Come fall, I noticed that when the furnace came on, the fan started blowing right away, which would be COLD air for the first couple minutes. That's not how it worked before, or how any gas/oil furnace I ever used worked. It still WORKED, but I was bothered by the discrepancy. Recently, I remembered that "gas/oil-electric" switch, and set it to "gas/oil." NOW my furnace works normally, the burner heating the firebox before the fan starts up. Which means that I'll have to remember to change this switch about twice a year. That's why I'm only giving it 4 stars (updated to 5). If the couple minutes of cold air don't bother you (or you have an electric furnace, I suppose), this won't be a problem. But my previous digital thermostat didn't have this issue (or the switch), and I've ALWAYS had either gas or oil heat. I guess I just consider it clumsy, and don't see why this couldn't be done better. <UPDATE>: With advice from a comment, I found this has parameters that can be set to resolve my issue. The manual is available in PDF format from Honeywell. It's still acts a little different (my central A/C continues to run for a bit after the temperatures "makes") but that's not a problem, just something that makes me go, "Huh."

This was super easy to install...the only thing I didn't understand is the metal jumper piece that was in the RC and R slots. I had an RH connection in my old thermostat so figured the R would be the correct position in this thermostat. Well, it IS, except I had removed the metal jumper piece because my wire went to R. During my test, the heat turned on, but not the air conditioner. Turns out you have to keep the metal jumper in, along with your R wire in order to make the connection to the other unit. I figured I didn't need it because I didn't have a wire in the RC of the old thermostat. Worked like a charm once I got it back in. Love the simplicity. Feels solid too. I didn't like the slider bars under the unit I had---the buttons on the face of this one are much more substantial feeling when you slide them back and forth.

I had a programmable unit prior to this one and what a pain that was to use, only lasted me less than a year, it started with the A/C not turning on and then the heater, this one is simple on/off, set temp and done, installation was a piece of cake, 2 screws for the base that matched exactly where the other base was, 4 wires screw them on tight insert 2 included AA batteries and you are done, saved my self the hassle of having a stranger in my house and charging an Arm and Leg.The wires are color coded and the thermostat has letters corresponding to the color, can’t go wrong with this, if you are having problems with your HVAC system should give this a try.note : Picture of base if from my old unit, just posted to show wires, Red Wire is power, Green wire is Fan, Yellow is A/C and white is Heater.

it's simple and it works. has flexibility to cool and heat. i love tech as much as the next guy with items such as NEST but sometimes simplicity just works for me. our home is a single story 4br home and this keeps our house at a constant temperature during the winter.

A service call to the local heating and A/C guy resulted in nothing more than a $120 hole in my wallet and an admonition to get a new thermostat. Naturally, he had one that he would sell me for $150 plus installation. When I didn't take the offer, he warned me: "Don't be tempted by inexpensive thermostats. They're crap."So I bought this inexpensive thermostat. I'm a contrarian: if someone says "don't do it" without good reason, I do it.Installation took about 30 minutes (I did it myself and I was lucky: my wires were all correctly color-coded.) The thermostat maintains the temperature to within one degree, reliably. If I set it to 70, the furnace comes on at 69 and goes off at 71.The verdict: It was easy to install. It looks expensive but it's not. It works VERY well.

Very simple. It seems that unless a thermostat is internet-enabled, most people never use the programming features of modern thermostats. This one avoids the unnecessary complexity, allowing even old people to use it.It also independently remembers both the heater temp and the a/c temp, making it easy to switch between the two systems without resetting each value. This is a great replacement to an old dial/lever thermostat -- digital displays offer precision to 1 degree thus eliminating the fiddling required to get just the right temperature, as with old systems.The installation guide is straight-forward and took about 15 minutes.

Installed two in Les than an hour, work well.had to climb up to attic to turn off the power and connect the C wire. Setup takes a few steps, follow the instructions and be patient, you'll be fine.One of the unit had one loose wire socket, so one the wires is not secure but just sits there, may cause problems later on, too lazy too exhangeI've always had Honeywell in the past 20 years,they are basic features but reliable. That's what I like.Not getting those fancy smart device things, it is out of control, we will all be brain dead.

I ordered this to control a gas stove we put in our basement. I wanted a WIFI thermostat so I could remotely turn the heat up before we went downstairs for the evening and then automatically turn down at 10 PM when we go to bed. The thing I don't like about it is that you can't have the back light stay on all the time. I have a Honeywell touch panel one in the hall upstairs which controls the HVAC. That one you can have the light stay on.

As a control freak and someone who occasionally forgets to change the thermostat before leaving for the day, this was an affordable solution that works for my needs. Haveing a similar Honeywell unit previously installed - the wiring was nearly the same. The biggest headache came from the WFI setup and im a damn computer tech. The bottom line is there must be NO SPACES in you WIFI SSID. I didnt test underscore ( _ ) but my assumption is it will not work either. Also, do not use special characters in your SSID (!@#$ etc) as they really arent supported.Another thing I didnt see mentioned in other reviews that i saw is that there is no data logging - you cant see what the high/low was yesterday or anything logging/data anywhere. You are literally just getting a Wifi controlled thermostat and for MOST people this will be enough. Abrupt weather changes/changing while on vacation/ easier programming schedules -- great for those instances. This will be a temporary unit for us until we replace our heat pump and air handler. Then we will decide on new WFI thermostat since there are rebates available. Most likely will not be another Honeywell unless their higher end stuff provides more control/data (logging temperature, prevent emergency heat, estimated costs, etc). In the end, i got what I wanted - a wifi controlled thermostat to change when I forget too. Now that I have it - i now know I want more

Easy enough to connect (take pictures of the wires before removing old one) physically and then electronically to WiFi. Register the device with Honeywell and install the Honeywell app on your smart phone. Using the app (or even via the website interface) makes it much easier to modify the schedule. Plus, you can configure the device to send you an alert if the power goes out. It's hard to get excited about a thermostat, but this one worked where the Nest did not. We've got two of them and for much less than 1 Nest. The WiFi setup can be a bit daunting for those less computer savvy, but if you follow the manual it will work. One item of note, if you connect and then change your Wifi password or network settings - in the manual, it walks you through "forgetting" the WiFi settings so you can connect again. That is easier to do than setting it up, but you will need the manual to decode what the numbers mean.

I have only furnace at home (no A/C). There were three wires to my old thermostat : Rh, W and G. Rh was jumped to Rc, but probably not relevant since I do not have an A/C. I shifted G to C at furnace and used it for C at thermostat. WiFi setup was a breeze and I could remotely control the system now. 4 stars because of an issue with the website. I can't change the schedule online. It says "Schedule Loading It normally takes 10 minutes...." every time I visit. If it ever loads, I will update here. Let me know whether anyone else faces this issue.Update. The issue "schedule loading" persists. Customer support gave me two options 1) wait for a few more days or 2) a complex hacking/resetting method. I am not ready for the second method so I am still waiting. While waiting, I am giving three stars.Update (11/2015). Honeywell fixed the issue at server end. It works as expected on apps and websites. I recently had to change the wifi router password. Resetting wifi parameters is not straightforward - you have to press fan and up button and select item 39. I wish they explained this in the manual.

This is a great idea and, once installed, works like a charm. I was disappointed in that it cost me over $500 to have 2 of them installed. The website says its easy to install and I'm no stranger to electrical work, but for my situation (my house is 14 years old), I could not install it myself and it took 3 installers 4 hours to make them both work. That said, they do work great. I have been across the country and was able to adjust the temp settings in the house via my iphone. The programming was easy and quick and I think we are saving money on oil.

Works as expected. Hopefully this unit will outlast its predecessor, which was programmable. We purchased this because programming was not always executed as programmed. So we like the idea of manual operation. Biggest loss with this step-down is the lack of an automatic transition between heating and air conditioning, but I knew that going in.8/28/17 Update: Very pleased but took back a star in my rating because the loss of automatic switching between heating and air conditioning seems it will be a fairly negative thing and to my way of thinking that could have been designed in easily and cheaply.

I bought this thermostat to replace a programmable thermostat. The programmable thermostat was complicated and not reliable. This one is perfect. It is simple, easy to use, and easy to see. I like the fact that it is back-lit and digital. My only complaint is not about the thermostat but about the Honeywell "Technical Support". I called them just to confirm the right wiring connections. I could barely understand the rep. He spent the entire call getting my personal info (email address, phone #, etc.) then once he got all that he told me to call a contractor to install the thermostat. Really? A Honeywell Technical Support person in the thermostat department can't answer a simple wiring question about their most basic thermostat? Luckily I found a YouTube video showing the install of this thermostat. It was actually pretty easy. This Thermostat gets 5 stars. Honeywell Technical Support gets 0 stars.

No frills and performs exactly two functions (heat on and off)...just what I wanted. The build quality is okay. Feels like cheap plastic and depending on how often you need to replace the unit's batteries, I can easily see the casing cracking (or breaking) at the hinges. Don't expect more for what you are paying here - sub $30 thermostat. The display is easy to read with a backlight screen. The information displayed includes the actual temperature (the larger number displayed) and the desired temperature (smaller number displayed in the upper right hand corner).I'm not an electrician, but the unit was easy to install (thank you YouTube for the numerous tutorial videos).For as many people who want the newest and greatest technology and functionality, there are still those who want nothing more than a simple on/off thermostat. This is that simple option. This item is a definite go.

I have had this for four years and it has worked flawlessly until now. It's brain-dead simple - which is a good thing, as the programmable ones never seem obvious or functional. Only now, the temperature number looks weird - there's a number there, but it looks like it's preceded by a + or -, and I can't really tell what the setting is, so I don't know what temperature the house is supposed to be. I'll probably replace it with the same item. I did take out the batteries and put them back in - made no difference. Perhaps it's just planned obsolescence.

Works good, but the temperature is about 4 degrees off and I can't find any way to adjust it so it's correct.

This is a good simple thermostat. I like that the numbers are back lit as soon as you press the up or down button. It doesn't seem to cycle too often. I like the accuracy of a digital thermostat, but never had the need for one you can program. This fits the bill nicely. I had a question hooking it up, and their customer service was easy to reach and helpful. Update, It takes a battery to run the back light. The battery runs out pretty quick, and you're left with a flashing "replace battery" on the screen. Would have been much better if the light was powered by the 24v transformer.

This model works well and the app is fairly easy to use. I would have rated this a 4 or even five except for two things:1. The Honeywell documentation is weak, particularly from a troubleshooting perspective, and the phone support is even worse.2. This model has a software bug that does not allow the wake time to be set at 2:00 AM or earlier. The wake set-point will be ignored if set earlier than 2:15 AM. Email support claims this is a "calibration", but this "feature" isn't documented and I have used several other brands of programmable thermostats that don't have this handicap.

Pros:- Easy Installation- Easy Configuration/scheduling.Cons:- Loud clicking sound each time the thermostat starts/stops the AC (Very annoying).- Cannot control using local WIFI (LAN). You must control via internet using mytotalconnectcomfort.com website.

Product is okay, but could be better. Their controller app for Android is very, very basic and needs a LOT of work, but it functions for VERY basic stuff, if you don't mind it crashing and having to restart a lot..I do wish, though, I had waited 2 weeks, as the price dropped $10.00.Yes, I would very likely still buy it, as I live in the Desert southwest and need to reduce my power usage to as close to zero between 3:00 pm and 6:00 pm. But any programmable t-stat will do that.If their wifi app interface was better, it would be worth 4+ stars,,

As other reviewers have noted the set-up of the WiFi is no simple task. I do not knopw what the problem was the first two time I tried but finally had success on the third try. The biggest frustration was getting it into "Wifi set up" mode. The in structions said that if "when" the set-up fails you need to pull the unit off the wall for 10 seconds and it should start over. In my experience this did not work even when it was unplugged for over 5 minutes. There should be way to force the unit into wifi set-up without pulling it off the wall. On the programming front it was very tedious until I noticed the option to set multiple days to the same schedule. Too bad this was not explained from the start so that I could have avoided the frustration of setting up Monday, Tuesday and Wednesday on the same schedule.

This product worked as advertised eventually. Tech support from Honeywell is essentially non-existent. The thermostat apparently is not compatible with my Zyxel router from Centurylink. Called tech support and they could only read me the manual before hanging up on me and not calling back even though they asked for a call back number. When I called back, the new tech had never heard of a firewall. You will need to have someone who is internet tech savvy to make sure the WIFI hookup will work. In some cases, router ports may need to be opened. I had to disconnect and essentially reformat the thermostat about 8 times before it worked. Most was due to the router incompatibility.

UPDATE: After two years, it started behaving erratically (maybe got fried in the same storm that took out my computer?). In any case, for a replacement I opted for the Sensi UP500. After using the Sensi, I've lowered my rating of this product from 4 to 3 stars. See my review for that product.Basically, it does what it's supposed to. It's relatively painless to install (assuming you have the correct wiring setup and wireless network). And when combined with the app and online access, it's very easy to use.The mobile app is pretty good, but (annoyingly) requires you to login with an 8-digit password every single time you launch. And it's missing some really no-brainer features, like a "change filter" reminder, or the ability to automatically switch from heat to cool, based on a temp range. Or location awareness (my phone knows when I'm home, so why doesn't the app pass on that info to the thermostat, and adjust the temp accordingly?)The website is a little clumsy (it's not at all clear how to get from the landing page to the schedule). And I was really disappointed to see there's no data tracking (How long was my system running over X period? etc, etc).But for a fraction of the cost of competitors, it's hard to complain.USER TIP:I noticed shortly after I set the schedule, that the AC was turning itself on BEFORE the time I had it scheduled to go to a lower temp at bedtime (up to an hour early). I couldn't figure out why, so I contacted support. This is the email I received:[Adaptive Intelligent Recovery, also known as Smart Response, is a feature that allows the thermostat to turn on the system earlier than programmed, so the house is at the programmed temperature by the onset of the comfort period. // The Adaptive Intelligent Recovery feature calculates the recovery ramp based on the number of degrees away from the desired set point and previous equipment performance. The recovery ramp determines the optimum time to turn the heating or cooling system on. If the set point is reached too early or too late, the ramp is adjusted for the next day's recovery, until the set point is achieved at the desired time. // It is necessary to allow the thermostat at least 10 days to "learn" a new program. If the set point is adjusted or the thermostat is switched to off during the recovery period, the thermostat interprets this as a new program input, and the learning period restarts at day one. Please be patient while your thermostat is in this learning phase. // If you would like to disable this feature, press and hold the Fan button and the up arrow key for five seconds. The screen will then change, and you will see two numbers appearing. Press the Next button until the number on the left becomes 13. Use the arrow keys to change the number on the right to 0, then press done.]

It looks good, but doesn't tell me how to wire it ?

Pretty standard and easy to set up although the face plate did not snap on very securely, which is a bummer.

Just ok

Works great except clicking sound

Product is very good if all you want is a basic non-programmable thermostat. Perfect for that. But the installation instructions are hopeless.complicated, confusing, almost unusable. the online support was down for maintenance; the phone line was overloaded and hung up on me.I resorted to You Tube and got it working.

works but the screen and numbers are small

Very difficult to connect with Windows--actually I never did get it connected. The description does not say that you need a "C" wire--only when you open the installation manual does it mention that. The manual also doesn't say what a "C" wire is, or where to get one (you need a separate transformer), which means another wire in the wall. The customer service video was no help, nor was the call-in customer service. I ended up returning it and getting a more expensive, but more user-friendly brand.

Well it looked good, felt good but you know what? I wouldn't recommend it in an older home.Why?THAT DARN C WIRE!!!Yes, they have instructions on how to bypass the C wire and make it work, but you give up manual control of the fan, and you have to make concessions that you don't have to make with some other brands. There's a difference between a thermostat that works well, versus a thermostat that you have to make work. Being that I would have to "make it work" versus simply wiring it in and being done, I chose to return this product and buy another.

This is a tough item to rate. I loved the ease of installation. It was up and running within minutes. It connected to Alexa without issue. The interface is excellent. The Honeywell app is very usable. However, I had to return it. The temperature differential, otherwise known as the cycle rate, is +/- 0.5 degree. This thermostat was turning my compressor on and off within 5 minutes only to do so again within a minute or 2 when the temp went back up a half a degree. It probably cycled at least 10 or 12 times in an hour. That kind of constant on/off pulls a lot of power unnecessarily and causes additional wear and tear on the hvac system. Honeywell service center days that there is no way to change the differential and it is set that way to maintain as accurate a temp as possible. I returned this unit and purchased an Emerson SensiSmart. That unit allows the owner to set the cycle rate to slow, medium, or fast. I rated this one at 2 stars because in my opinion it is unusable, but I can see how other people might prefer this level of accuracy and, as I said at the beginning, I love everything else about it.

Minimally, the thermostat works. Several gripes will keep me from buy any more, however:1. I'm not sure the quality is there - In 3 years I've had 1 DOA, 1 quit working completely, and 1 quit working reliably.2. The Honeywell iOS app doesn't always work reliably.3. It's kind of dumb that a smart thermostat can't set its own time from the Internet.

Great thermostat, horrible service behind it. This is about the application service to remotely control the unit. When it works, it works great, but it has a frequent down time, and the folks at Honeywell don't seem to fix things that happen on their servers after hours. Just last night/this morning, it was down for about 12 hours. The application would throw an error that it can't connect to the servers. Tried on multiple devices, networks, all the same. The thermostat is on the network (i can ping it). Then suddenly after 8am this morning, it starts working again normally. I will also get notifications that the thermostat is offline, but I can see it on my network. I wish there was a way to override the remote access and go local network access only. Fortunately, the thermostat just continues as it should connected or not and you can control it locally.

The thermostat is fine as a wall thermostat, but the Wi-Fi remote connection is very unreliable. If the home Wi-fi drops even for a moment the thermostat needs to be reprogrammed and the remote connection will not work until it is set back up. The occasional convenience is not worth the aggravation of physically reprogramming the thermostat every week. Do yourself a favor and find something more reliable.

i thought i bought the expert instalation too, but lo right AFTER i received the thermostat, I RECEIVED A NOTICE THAT AMAZON COULDNOT PROVIDE ME AN EXPERT FOR THE AREA WHERE I LIVE, WHICH IS OKLAHOMA CITY......Watch out Folks!

I've read where buyers have had problems installing this unit (the instructions are indeed bad), but I, fortunately, didn't. It went up in a jiffy, and worked with my furnance and air in the 'default' mode – no tinkering needed.But I can only give it two stars because of a major problem... the Set To temperature keeps changing on its own. For example, one time I set the cool temperature to 77º, and a couple of hours later it read 80º. Same problem with the heat setting. It just will not stay to what I set it at. Very, very annoying.

Does my work with my electric furnace. It does my shut system off. I called for support and they told me to get a contractor I will return when our contractor replaces it

Quit working only after a couple of weeks

Don't expect to get any help from Honeywell tech support if you have an issue with it as I did !! Your call will be answered by a foreign call center (India) and informed that this is a pro model and they WILL NOT give you any help. You must call a licensed Heat/Ac guy for help. Add 50-75 $ for a service call.

This did not work out. My existing Trane thermostat has a W2 wire that isn't useable on this Honeywell. Tried to get installation info from Honeywell before and after purchase to no avail. Apparently they expect you to contract with a pro. I am returning it..,

I am very disappointed with this product. I wanted a thermostat that could be controlled from my iPad. After downloading the app from Honeywell I am unable to control when my heat goes down at night and up in the morning.I would return this product except It is already installed and I would be out the installation costs.DO NOT BY THIS PRODUCT!

Could not get thermostat to work with standard HVAC a/c-gas heat system. Used a transformer to power "c" wire and unit powered up, but would operate properly. Had to return to Amazon.

when i installed the thermostat it tried to set itself on fire. but the single star (should be no star) is for the dealer, not the thermostat.In late march of 2017 i bought the "good as new used" honeywell wifi, programmable thermostat (RTH6500WF), from EverythingDeals, The package it arrived in looked fine and the unit looked new.. I didn't remove the thermostat from its package because it needed the "C" wire attached and my furnace system didn't have one. I decided to wait running the C wire until this fall because there was little need for the thermostat as it was intended to replace a working older one.this month i got around to running a pair of wires to the thermostat location. (C and Rc). as per the instructions I attached the two furnace wires to R and W and the two new wires from a 24 volt transformer to C and Rc after removing the jumper between R and Rc. triple checked to be sure the four wires were in their proper placement in the wall plate. checked to be sure the voltages were correct.When i plugged in the thermostat to its wall plate the display did not light. in a moment i smelled hot electronics and immediately pulled the thermostat off the wall. part of the plastic housing was very hot and had started to bubble. And there was something rattling around inside that had not been rattling before. not sure what happened, but clearly this was not a good as new thermostat.in talking with honeywell's overseas support about getting it repaired i was very nicely told i had to deal with the seller (EverythingDeals) to get it repaired, replaced or returned. But of course EverythingDeals has a "we don't care what happens after thirty days" policy.the galling thing is i had previously installed a honeywell T5 wifi thermostat and had no trouble doing it, including running a pair of 24 volt C and Rc wires to it. the install was no more difficult for the rth6500wf than it had been for the t5. the wiring was the same. the places for the wires on both units were well labeled and labeled with the same letters.so - bought a second t5 from amazon. used the same wires in the identically labeled sockets (removing the jumper) installed it with no problems (no burning) and it works as advertised.perhaps i am wrong but it seems sensible to think the unit was never tested to see if it actually was good as new. buyer beware.

Product would not work. Wired according to instructions. Has the same configuration as my current unit. Defective.. Seems I'm a day late in returning it... Not a Happy Camper....

Just installed it, but am one day beyond the return date and it does not work. Won't turn the air conditioning on, and it is wired correctly.

They die and when they die, they can cause big problems. I had one randomly change the set up program and instead of cooling, ran the heat pump up to 95 degrees before I returned to the house and found it--the heating contractor figured out what happened (that happened 4/22/17). Another house on 4/27/17 (fifty miles away from the other failure) suddenly went to heat while the thermostat was set to cool. Even turning the thermostat to OFF didn't cure the problem so I had to turn the furnace off. I've owned five of these over the past four years and used them in three separate locations; four have failed.

the sensor doesn't work properly

Broke after a few months

Never worked right, we put it in our motor home and finally had to order a whole different one.

Just now got around to installing. Unfortunately, I could not get it to work and I missed the return window by 3 weeks. I have installed many thermostats, some much more complicated. I believe the one I got was defective as I could not get the A/C to function. Besides programming for electric v. gas v. heat pump, the only other option was to leave or remove a jumper between R and Rc, depending on whether one or two transformers were supplying voltage. Tried both ways- no dice- only hot air. Reinstalled the old Honeywell and the system worked fine.YMMV

This product worked for two weeks, then broke in the middle of the night outside temperature was 12 degrees. Not even thinking my new thermostat could be the problem I had to pay for a service call, when they came out they said Honeywell were junk and replaced it with a different brand.

Bought two of these and both internal thermometers run 5-8 degrees warmer than actual. There is no reset.
