Side by Side Comparison of: Honeywell

Works as advertised. Got it two bucks cheaper here than at Menard's. Realising we only paid $22 for this, that little black smudge in lower right of display which some complain about, and is only visible when the light is on, is very insignificant and of no consequence. Silly people. Since wife is home all day, I have wake, leave, and return all programmed with the same time and temperature of 72° @ 5:45 a.m. Sleep is set for 65° @ 11:00 p.m. everyday. Weekends have wake, leave and return set for 8:00 a. m. The backlight feature is really nice in our darker hallway. Lights up when pressing the run button to check time and temperature. Fairly easy to program. Recommended.

The product arrived on time as promised. Although I am pretty handy with electronics and am pretty literate having a Juris Doctorate, I had trouble following the printed included instructions when it came time to program the thermostat. Fortunately YouTube had several videos showing how to operate this particular thermostat. After watching one, programming seemed easy. I am satisfied and can report that it works well.

Our old thermostat wasn't controlling the temperature at all and we actually thought we had a problem with our AC. I decided to try this first, and didn't want something fancy. I installed this today, which took less than 30 minutes start to finish with clean up and finding my screwdriver. The AC came right on and my house finally cooled down!It isn't super fancy, but the programming is pretty nice and our old one didn't have that option. It's been at least a month and it is still doing well.

Excellent thermostat. Easy to use and to install.update: thirty days after installing I got up one morning the screen was blank. Nothing worked. Changed batteries, nothing. Hit it on the palm of my hand and it started up again. This makes two in a row I had the exact same thing happen.

Works great. Tip: Don't do what I do -- read the damn instructions first. Rule #1 - LABEL THE WIRES. I foolishly assumed yellow would go in the Y slot, but in my case it went in the W slot...and Blue went in the Y slot. Had to pay a Just Answer HVAC guy to help me straighten out the mess of my own making.

This thermostat does exactly what it says it is going to do. It was easy to hook up, easy to program, and if you are on a regular schedule like myself I don't see the point in spending a few hundred dollars on a smart thermostat when this can do the same thing for 25 bucks.To hook it up I just removed the old thermostat, took a picture of the wiring, then wired this up the exact same as the old one. You do need a very tiny screwdriver to make the connections, but I think that is probably true of any thermostat. You also have to put batteries in it.

Easy to install, and program. I set the get up time/temp, leave time/temp, arrive home time/temp and go to bed time/temp. I set it once and it works every day!

honeywell mis-advertised this product, it is not 1 week programmable, it is one day, 4 periods per day. the next, (more expensive) one up is one week. however i do not need or want 5/2 days program. this has significantly reduced heating costs on a williams gravity room gas furnace. the thermostat they include is junk.so if you do not need sat sun programing, get this at best price, a lot of returns due to honeywell mis-advertising. they should fire exec in charge of advertising.

The setting you input will remain in effect all 7 days of the week. This wasn't very clear to me, and apparently if you want a thermostat that will adjust on the weekends, it needs to be a "7-day" or a "5-2 day" thermostat. Install was easy, going from an old analog mercury thermostat to this one. The "green" wire was actually blue, and "red" was a very faded pink, but my old thermostat's circuit had the appropriate letters on it, making identification easier. I took pictures of the dismantle each step of the way to help me backtrack if needed. As a thermostat, it functions well. However, the description, and even the packaging, confused me into believing it was a 7-day device.Update: increased rating to 5 starts (from my original 3). The thermostat works well and overriding the program on weekends is as easy as adjusting the temp one time each day, so it's really not a hassle.

We had an old mercury theromostat in the house that was off by about 15 degrees and would trip every time you walked past it.Summer is on the way and I wanted to cool the house better and was thinking of buying a floor fan.Looking at pricing, it made more sense to go with a new thermostat.It took about 10 minutes total to remove the old thermostat and install the new one.I left in on the pre-programmed weekly cooling schedule and it has done wonders already.The true test will be when the next utility bill comes in!

This thermostat works great for my needs. Since there are people in and out of the house all day long, I just wanted something that would simply turn the heat down at night, and turn it back up again in the morning without anyone having to think about it. It doesn't have any major features or frills, but it works as it's supposed to. You can actually set it to come on in the morning and heat the house before you get out of bed, then you can set it for a different temp when you leave for work, and then have it kick back on again before you get home from work, and then finally low again for nighttime (if you like to save energy). It will repeat the programming you set for 7 days a week. It does not allow for separate settings on different days or weekends. You can manually change the temperature and it can retain it temporarily (it'll go back to the temp settings at the next time setting) or you can press the hold button and it'll hold that temperature until you change it or press the run button.Very easy install. If you're like me and have been lazy about upgrading (I know I'm way behind...) then just do it already.

I wanted a simple to install thermostat to replace the aging, mercury switched Honeywell items that control our heat and cooling. After researching I decided that a simple weekly timer is good enough, and certainly better that what we had originally. The RTH221B shows the current temperature and can be set to adjust the temperature when you wake, leave, return and night. It is simple to use with 15 minute increments.Installation says "15 minutes or under" and I found this to be true.To install: Turn off power to furnace and thermostat (although it is a low voltage feed, you MUST still do this) Unscrew the original thermostat from the wall but leave wires attached Check the color of the wires and which terminals they attach to on the original (look for small letters W,R,Y,Rc etc) Mark the wires (if needed) with the stickers provided in the package Unhook wires from the original Remove backing plate from new thermostat, thread wires through hole and place against wall Attach backing plate using screws and wall plugs provided Put 2 x AAA batteries(NOT supplied)in the faceplate Attach previously marked wired to the matching terminals at the back of the faceplate Snap faceplate onto backing plate Read instructions for setting time and programs Turn power to furnace back onPros: cheap, easy to install, good instructionsCons: would have been nice to include 2 x AAA batteriesOverall a good buy. I fitted one as a test and then bought 3 more.

I thought I was going to have to replace my furnace because it just was not heating up according to the setting I selected, and facing such an expense was overwhelming for me at this particular time. Necessity is the mother of invention, they say, and in my case, I become more creative. I decided to buy a new thermostat to see whether that would help and if not, then I'd go for a new furnace. A handyman installed the new thermostat and my house has been evenly heated according to the selected setting ever since. I particularly am relieved to actually be able to read the larger display panel and the instructions for programming are simple enough. The price was reasonable as I checked local sellers that were slightly above or the same as the cost online, and it didn't require me going shopping.

Just Installed, will watch for accuracy, replaced an older model Honeywell that seemed to become inaccurate for temperature reading after about 2 years. Easy to install, it does accommodate newer systems. My HVAC system is pretty old, so I only use the Hold Temperature Setting and I do not program as my system can't handle constant programming changes, this was learned after burning up a few circuit boards on my system. Initially installed this Thermostat seems pretty accurate within 1 to 2 degrees based on numerous other temperature reading devices that I keep near the thermostat. I will update with any new changes. I only purchase at full price with no offers or discounts.

I do not (auto) in the window where heat and cool are. Will the auto switch work this way? There is a note in the literature that says depending on the installation. auto may not be visible in that window. There is not any info stating whether the auto feature will work if not visible on screen.

I always wanted to switch to a Programmable thermostat. I Wanted it replaced for conservation reasons, just in case I forget to turn the air/heat up or down when leaving the house. i don't want the AC cranking all day while I'm not there, hopefully this will save on my electric bill. Florida days can get quite hot. the installation was surprisingly easy as i already had a Honeywell non-programmable thermostat so the switch over was simple, as it has the same wire set up. I also bought the cover plate that goes between the wall and the thermostat that covers up the hammered wall and makes it all look clean again.

I had a non-digital thermostat, and the temperature in this place fluctuated wildly! This sweet little thermostat took care of that. It maintains the programmed temp extremely well. I have the daytime temp set at 71, and it ranges between less than a couple of degrees. At night, it takes it down to 65 and keeps it there until 6 am. Love this thing.

After messing around with quite a few thermostats from Menards, I finally realized I needed to do some research. My research consisted of look at what we use at the church I work at.... Oh look! Honeywell still makes really functional easy to understand thermostats (not quite as easy as those old round beauties, but still pretty decent). Then I headed to Amazon to see how much they would set me back and I was pleasantly surprised they would not require a payment plan. Research Completed, Order Submitted. Thermostat arrived packaged well and installed with ease. It even came with a really extensive instruction book which I completely ignored because I just have a simple heating system and because I am a man and reading instructions is something I only do if I run stuck or break something trying to do it the wrong way : )

At first I was worried about replacing my thermostat as I have heard horror stories on issues they had. I took a leap and purchased this one and it was so easy to install. Everything was labeled and the instructions were very detailed. It took me about 10 mins to replace my existing thermostat and another 5 mins to figure out the programming. All in all it is a good thermostat for what I need it for.I did have the mark on the bottom right of the screen that everyone has complained about and it is strange to see but I don't plan on looking at my thermostat too often.

I research every product that I buy online. After reading several reviews, I concluded that this was the best choice for my needs. I have a gas furnace and electric central AC. My old thermostat was calibrated about 2 degrees too warm, and there was no way to fix it, so for $23, it was worth buying a replacement. I looked at Lowes, but I didn't see this exact model in the store.I had never replaced a thermostat before, but this was extremely easy. I had my toolbox ready, including a small precision screwdriver, & it took me 7 minutes to install it. There are countless YouTube videos explaining how it's done, but the manual instructions are sufficient.The thermostat works great! It is simple to use. Programming it also dead simple. I like the fact that it doesn't have a hinged door that you have to open. All the buttons are always visible and easily accessible.The only reason I withheld a star in my rating is that the green LED screen has a bit of a smudgy looking flaw in the right 1/3 corner. It's not noticeable unless the screen is lit, but it's still a flaw, so I can't give it 5 stars. However, it works, it's easy to install, & the price is right. I would buy it again.

Easy enough installation. Has worked well so far. Display is not that easy to read without the back-light and the main numbers are a little smaller than I hoped.I am not using the cooling side since I have no air conditioning. It presented no problems working with a millivolt furnace.

I replaced an ancient Honeywell round thermostat with this one. I was initially going to purchase a much more expensive model to hide the cabling better but I just put this on top of the old gold faceplate that came with the old honeywell thermostat. Looks fine. It took about 15 minutes to install. The tools you will need:-Ideally a power drill or impact drill with a phillips bit to remove screws, and install new screws- a watch battery screwdriver to connect the black and white cables.- The box does not come with one.After two months of using this unit, there were no cost savings. I just didn't have to adjust the thermostat each morning and evening. What did happen is that this caused my ancient boiler to run inefficiently (the boiler would come off and on consistently when cold) causing my gas bill to go up significantly. The aquastat had to be adjusted and the low setting and differential were decreased by a homeservice heating professional.

Pretty decent, especially for the price. Two complaints: the LCD is poor quality and there is what appears to be "dust" (little black speckles) inside the LCD on the lower right hand corner. Other complaint is there is no C terminal so that the unit can run without batteries. The unit I replaced with this Honeywell was a super cheapo GemTech, but could be powered off the C wire, with batteries as a backup power source.Lastly, while not a complaint because I knew what I was getting, I wish they let you pick the degree difference when to turn on. +/- 1 degree is too little for my location, so it's turning on quite often. I know there is a workaround by selecting max number of times it turns on per hour under the advanced settings, but I prefer to set it by degree difference.

7/14/14I just installed this thermostat two days ago and so far it seems to be working great! I have never in my life installed a thermostat and after watching a YouTube video, I was able to do it without calling anyone for help. It's very straightforward, especially if your wires are color coded. It comes with stickers to label the wires if you need to and it comes with the hardware needed to mount it to the wall.The only things I dislike - and the reason I deducted a star - is that it's really hard to pull the faceplate off. I'm a little worried next time I do it I might even pull the whole thing off the wall despite being screwed in. It also takes batteries only although from what I have been told they should only need replaced annually and even then it will tell you 60 days prior to it dying that it needs changed. Another downside is that every time you change batteries, you have to program your settings all over again. But that's just me nitpicking. For the price, it's well worth it and should save me a lot of money on my energy bill.

Very handy, simple to install and a perfect replacement for the old thermostat. So far, so good.

Very good alternative to the box stores. Has all the basic functions and comes with everything to make it a plug and play application.

It works. It didn't take me long to figure out, and I'm kind of a moron when it comes to stuff that require me to read instructions, because I don't like to read instructions. Simple and straightforward to install. Takes about 7 minutes. Why spend more?

My house was built in 1974, and the thermostat we had was original. It was hard to get an accurate temperature reading from it and I wanted something cheap and programmable, so I bought this Honeywell unit. I'm mostly satisfied with it - the install was a breeze, the instructions were clear, and the unit functions perfectly. The only gripes I have with it are that the screen is not backlit and there was no option to hardwire it, meaning you have to use batteries for it. However, at this price, I can live with those complaints.

I have been using Honeywell thermostats for some time, all with good results.I purchased this one to replace a non-programmable version and it is performing as expected.The only negative that I found with this model was the labeling of the terminals inside: the red wire label is shifted such that the unused terminal can be mistaken with the one intended for the red wire, especially since the correct one has a wire bridge to the adjacent terminal; two wires go into the red terminal: the red itself and the factory equipped bridge.Other than the above, it is a good product and simple to use.

Being retired, and having an old failed Honeywell 5/2 day thermostat, we replaced it with this 7-day model for heating only. It was simple enough to replace. The twin wiring was identical and so were the wall mounting hole centers. The directions for set-up were fairly clear. My one beef is that the new thermostat lacks back lighting which the old one had. The letters are small enough where one needs a flashlight during setup, requiring three hands at times, and is awkward for those of us with just two hands. Omitting the back light is inexcusable since the 5/2 twin RTH2300 DOES have back lighting. Another caution is that you need a tiny screwdriver to turn the wire set screws. I happen to have one but I would guess few people do.

I already had 3 other of this type but was installing a new zone with a new boiler. The original 3 made loud clicks as the heat kicked on and off, but this one is quieter. There still is a minor click you'll hear though. Additionally, it did not come with screws or drywall anchors as indicated in the manual (from what I recall). Still, minor complaints for a product that works great and is much, much cheaper here than at Lowes or HD.

The instructions aren't the best. We did a little extra research prior to installing because we are not electricians. It is fully battery powered which is something I was not prepared for, but 3mo later the batteries are still running strong. The programed settings work correctly and are easy to set. It is roughly 3 degrees off from the true temperature so it doesn't turn off and on constantly. I was glad to see that. It is pretty decent for the price. Gave it a 4/5 rating simply because it is 100% battery powered. I would have preferred electric but so far so good.

I bought 3 but had to return one because one of them showed the inside temperature 6 degrees below the actual room temperature. This caused the thermostat to overheat the room. Amazon shipped me another one in one day which worked correctly. I would check all that you buy against each other or against another thermometer to see if the inside temperature registers correctly. That is why I rated them 4 stars. I finally ended up with 3 that are 5 stars

This thermostat seems to be a great replacement for my old one that was no longer working. The back light makes it easy to see at night something that my old thermostat didn't have. The only reason I gave it 4 stars instead of 5 is the wiring is a bite tricky so it took me a fair amount of time to figure out. All in all I like it very much and would recommend this thermostat to anyone looking for a low price replacement.

Just installed this unit yesterday and it is working great. The only problem is that I had to call Honeywell 3x before it was working properly. All 3 customer service reps very nice but wish there would have been more comprehensive instructions to not have to call at all. Calling was not very painful though. Git through to a rep pretty quickly.

I got 2 of these to replace similar thermostats that could only handle one program for the entire week. I needed one that would match my routine of different timings for the weekend. This model does that and is way easier to setup and monitor what is going on than the old ones.Installation was very easy with clear instructions and almost impossible to get wrong. I have a fairly straight forward heating/cooling system but there are detailed steps and diagrams for more complicated systems like heat pumps etc if needed. Setup was also very easy with well documented steps for the initial system match [so it understands what it's controlling] and scheduling the time/temperatures was also easy thanks to the well laid out display.I have had these in for a Month now and am very pleased with the results, I would recommend them to anyone.

This is my 3rd one. I bought first two for each unit in my house 5 years ago. One of them started acting up with flickering screen and lock ups after 2 years then it died few days ago. I tried resetting it and cleaning the contacts but it was completely dead. I didn't want to buy different one so I just bought same one so I don't have to switch out the backplate.

had the same issue as many others have. It works, but the LCD screen definitely looks like someone touched it and discolored it during install. Bottom right quarter of the screen is all fuzzy.

I bought 3 of these at the same time. All 3 are in use but suffers the same material defect/poor quality control. All 3's LCD have dark patches at the same spot and pattern.

UpdatedMy original purchase started "eating" batteries. A new set of batteries would be dead in about two or, at most, three days. Only about two days out of Amazon's replacement period, I contacted them and they would do nothing but advised me to contact the manufacturer (Honeywell).Honeywell told me that they would replace the thermostat but that it would take about ten days to receive my new one. As were were having a cold spell, fortunately I had kept the old bi-metallic one that had been there and I had to put it back. NOT a happy camper!The new one arrived as they said it would and, once again, I switched thermostats. The replacement has been working properly for several months now and no sign of batteries wearing out. Honeywell told me that a set of batteries should last about two years so it will take a while to see if they make it or not. I bought good quality premium alkaline batteries made in US so there should be no excuse for premature failure.In my opinion, Honeywell stood behind their product though I think they could have used expedited shipping but...AMAZON? NOT SO MUCH! TWO days and they wouldn't assist me! I now think twice about where I purchase my items even if they do cost a little bit more. Just the principle of the thing!

Not super well made or fancy, but I don't think it's going to break tomorrow either. Mine came with a few spots on the screen that haven't gone away, though it doesn't affect the utility of the unit.

I bought this at a local Menards store with assistance of the staff. I replaced an old round Honeywell mercury-switch model. Have the typical 2-wire setup for a very ancient (40 years old?) natural gas forced hot air furnace. I decided to squeeze some savings on the gas bill by lowering the temperature during the workday when I'm never home for 9 hours, and also drop temperature overnight as I like it cooler while I sleep.Installation was a breeze. I work as an office equipment service tech, so I did not expect any trouble figuring it out, your mileage may vary in that regard though. I had the required small screwdrivers on hand. The mounting template perfectly matched the old round thermostat, so I just reused the old screws in the original holes in the wall. As I customarily do, I did read the installation and setup directions prior to installation.Programming was also fairly easy. What you have to understand here is that there are 4 adjustable times of the day where the temperature can be allowed to change. Exactly what the amount I needed for my purposes. If you wish for fewer adjustments, just set 2 or more of the consecutive time events to be the same temperature. This is how I handled the weekend program, as I only wanted to lower the temperature at bedtime and raise again in the morning. I left the "away" and "home" at the same temperature as the "wake" setting to accomplish that. Again, you can adjust the time of day for these events in 15 minute increments. I did not see anything confusing about this other than I would forget to push the set button and think I was adjusting the temperature, and instead was changing the time. The numbers being adjusted flash, so that was just me not being observant.The reason for me giving 3 stars is this: there is no adjustment for temperature on/off cycle. That old mercury-switch mechanical thermostat was designed to turn on the heat a couple of degrees below the set temperature, and turn off heat a couple of degrees above. That allowed the furnace to cycle on fewer times, and not waste fuel warming the heat exchanger each time. This cheap Honeywell digital thermostat turns on the furnace with only a dip of 1 degree F, off after warming to set temperature. My furnace in my 100+ year old home with little insulation started cycling on every 12 minutes for short bursts of heat. Turns out that the temperature cycle is factory set and cannot change. The only way to gain some control of this is to go into the advanced programming features and adjust the "cycles per hour". Default setting was 5 (maximum) cycles per hour, thus the furnace turning on every 12 minutes (5 times per hour). I dropped this setting to 3 (20 minutes wait between cycles) and may readjust to 2 in the future. Naturally, the manual does not explain the cycles-per-hour setting other than generic recommendations for different types of heating systems. I can see this becoming a potential problem with actually causing me to use more fuel than with the mechanical thermostat. I'll just have to monitor my fuel use and re-evaluate later in the winter. I may need to bite the bullet and spend 2-3 times more for a different brand thermostat that will allow me to adjust the heat cycle to something that approximates the old thermostat more closely. Wish I had researched this prior to purchase now. Cycling the furnace on-off more often can also lead to it failing, and I do not see how taking a 3-5 year loan to pay for a new furnace saves me money. Everybody I know that replaced furnaces with higher-efficient models during the 1990's are replacing their expensive furnaces again. Mine keeps chugging along.11-23-2013: I bought the Honeywell trim kit http://www.amazon.com/Honeywell-50002883001-50002883-001-Coverplate/dp/B00096JC72/ref=cm_cr-mr-titleAfter installing, I am noticing that the temperature is tracking more correctly compared to a mercury thermometer on a nearby wall. I suspect that the trim plate is isolating the theromstat from the wall surface temperature (which is cool to the touch usually). The temperature is not fluctuating so badly. Furnace is not turning on at regular intervals this weekend. It's also a lot warmer outside, so again time will tell on this.

Its a good stat. I wanted to use this in my RV as other Honeywell ones did but they said it wont work and it did not.

Simple to install and it worked great, but I ordered another one because I frequently wander downstairs in the dark and prefer not to turn on the lights.

Works fine but it's really annoying that the display doesn't light up. Didn't know that when I bought it and after having used it I can't recommend buying one without the light function.

Price was right. As previous reviews have pointed out, no back-light and only one week programming vs week days and week ends. This actually is fine for us since we're retired and every day is a weekend. Issues I had with the design included it was difficult to easily separate the back and front plate, without also separating the circuit board from the back plate. If no-one else had this issue, perhaps it was just this particular unit. We have moved a lot, so this is one of many Honeywell digital programmable thermostats that I have installed with this issue. The batteries also had the tendency to 'pop out'...had to clear tape them into complete installation. That said...price and base functionality was what I was looking for, and that's exactly what I got.Ps also like the much smaller 'footprint' this model takes up on the wall vs some other company equivalent versions.

I ordered 3 RTH221B units but was disappointed that all 3 units shipped were different models. They all work pretty well but instruction documents did not match the product. Had to guess how to wire up one of them. The programming procedure is different on each of them as well. One unit was clearly was not new.

I didn't know they still made thermostats without a backlit display! Very easy to install, but if you want to change the temp any time other than high noon, better have a flashlight.

The product really deserves a 5 star review. It works perfectly. BUT, only after I fixed it. With typically American quality control, the thermostat was shipped with a broken R-Rc jumper. Nothing worked - no fan, no cool, no heat, nothing. Obviously the thermostat was never tested. However the broken jumper wasn't obvious, so it took me hours to discover that. Once I replaced that jumper wire, everything worked as intended.

Doesn't switch automatically from AC to Heat as I expected. Had a little difficulty matching up the wiring and had to go to Honeywell site for further documentation

Honeywell is usually great, however the thermometer in the thermostat reads a few degrees cold. It works, but I just need to remember that the temp is not what it reads. I should have returned this for a replacement.

Not sure if package was opened prior to shipment. Here's what was missing: the jumper wire for a 4 wire set-up (had to make my own), no quick reference guide and no stickers to keep track of the wires (although that's not a real difficult chore). Most interesting and challenging was to figure out where to put the R wire when there was no jumper in the panel. Unless there's a significant difference between the 6350 and 6450 packaging, I am not sure what's happened here.

It's great, except for the "Smart Response" technology that's supposed to figure out when turn the heat on in order to bring the house up to temperature on time. I followed all the setup directions. After using it for weeks, it still brings the up to temperature 30 minutes before the time I set. That's like keeping the house too hot for 15 hours a month. I'm disabling this "smart" feature after I've wasted money heating the house more than I need to.

Works well and the backlight is great but there are two significant design flaws:1. There is no "lock" with which to prevent accidental modifications: e.g., touching the fan or cool buttons will alter the behavior of the thermostat.2. For systems without a cooler, this thermostat is overkill, and there is no way to really disable the cooling functions (e.g., to prevent mistakes). Not clear if Honeywell offers a thermostat without cooling functions.I wish I bought a simpler thermostat.

I have a heat pump and was unable to use since it was not compatible.

For some reason this thermostat is incompatible with our A/C however it works fine with controlling our Heating...we changed it out thinking perhaps it was a faulty unit but had the same issue.The switches used to control the thermostat Heat/Cool and Auto/Fan are very stiff.The display shows current temperature only instead of both current and programmed temperatures. Personally we prefer both displayed.

I was looking for a user-friendly programmable thermostat for my parents to replace their manual unit, so I decided on this one. Unfortunately, the one I received was defective. The motherboard was covered with a putty-like substance. Unsure if this would affect its functionality, I returned it. But, for what it's worth, this model looks nice.

The thermostat runs fine, it's great. The issue I have is with the display. Like many, many, other reviewers I received a unit with a black smudge in the bottom right hand corner that is only shown when the backlight is illuminated. I went to Walmart to get a new one, installed it, and saw it has the exact same issue. The complaints about this issue go back several years, and still they're being manufactured with this defect. Pretty dissatisfied over here.

first.. it was very easy to install. especially if you owned a similar one before and if you only have 2 wire heating system.. i installed it less then 10 minutes.. i think it took longer to find the screwdriver in the drawer..second. the product it self.. when i read the reviews everyone was complain that there was spotting on the lcd screen and i decided to get it anyway.. mine wasnt that bad but still there was spots on lcd.. kind of upsetting because the honeywell is a good company and for them to take out a product in this condition is unacceptable..finally.. would i recommend it.. it all depends if you need something cheap and works this is it..

The only reason im giving it 2 stars instead of one is because it was inexpensive. This thermostat does not keep the tempurature well regulated. I purchassed this to replace the only analog dial looking one that was on the wall, and so far wish i hadnt. It is fairly easy to get set up and to program, but the thing just turns on and off the heat whenever the heck it feels like it. For example: i may have it programmed to just stay at 70 degrees all the time, and it may be 60 degrees in the house and you cannot get it to turn on the heat, then other times when the heat is running it will keep the heat at 78 degrees for several hours and wont turn the heaters off!Im assuming unless all 3 i got (2 from Aamzon one from Walmart) of the same exact model are all lemons that it is just terrible, because all 3 zones that i have in my house are doing the same thing.

No backlight which make it useless if it's not in a brightly lit area.

Wouldn't here a schedule and wasn't backlit. Didn't realize how important that feature was. Returned and ordered a different unit.

Wish I could set separate schedules for weekday and weekend. The picture even shows a "Th" for Thursday on the display - this isn't even a function of this model. I misunderstood the description and thought I was purchasing the same model I had before. Doesn't really help at all unless you have the same schedule on weekdays and weekends.

Didn't work for mine outlet. Couldn't figure out which wires in the wall goes to where on the control.The slots in the thermostat are too small to fit my thick wires from the wall.

Don't know.. I am struggling with mine.. I have it set to lower the heat at night but seems that it doesn't. I verified settings several times and still am always manually adjusting..Not too happy but since already installed and mounted, will not return them.

It was very hard to program and when I set the sleep time and temperature at 11:00 PM and temperature at 10 degrees lower than day time heater came on at 11:45 I was already in bed and had to get up to shut it off. I figured you get what you pay for.

Kind of a pain to use. I have a two stage heat pump. The Thermostat kept losing program instructions. So when you would select ac you would get heat instead. You haft to select numbers according to what type of system you have. I would select what I needed, then recheck the settings and they would be different then inputted. Had to do that like five times till it accepted the program. Finally accepted the program and started working right. Meaning when I turn on the ac it blows cold air and not hot.Been two weeks now and thermostat is functioning properly. Has held programming, so far. Only one glitch at the beginning of the two weeks, I believe the third day after install. Lost program for some reason, reset numbers been good since.So my review is ''it works, very sketchy''. My suggestion is, pull off the old thermostat and match the numbers. Just trip the power off to the ac unit and they take apart old thermostat. Numbers are inside behind the old thermostat.

UPDATE: used for less than 6 months AND IT FAILED. Came home to a 93 degree house yesterday with furnace running non stop. As first step in troubleshooting, put the old non-programmable back up. Works fine. BOOOOOOOOOOOOOOOOOOOOOOOOOOO________________________________________________________________________________________This was super easy to program and install. We hope we're even happier when the next energy bill arrives!! I will say that the only down side I see to this is that it's hard to separate from the mounting plate. If you want to reprogram 'all' the time slots it's quite a lot to stand there while it's on the wall and do. I have had others in the past that 'just popped right off' with the right touch and I wish this one did too, it really requires a screwdriver to press in on either the top or bottom tabs to get it 'free' from it's wall mount.Other than that, the screen is easy to read and it is keeping the scheduled temp routine perfectly.

Pros:Easy to use, program, and install if you are a DIY'er.Cons:Product was not accurate. Temperature reading was off by three degrees. Markings on the plate and unit and missing wire label sheet suggest it was installed before and repackaged as "new".Recommendation:I returned this unit as defective because of the inaccuracy. I did NOT order a replacement from this seller because I believe they sold me a returned unit.

The thermostat was easy to install and easy to program, BUT it clicks. While operating, the thermostat has an audible double click before it turns the furnace or air conditioner on and again before it signals the unit to turn off. This goes on throughout the day and night. Our upstairs thermostat is in our master bedroom, and the double click is a nuisance.

Disappointed with the product. Instructions indicate two AA alkaline batteries required. The thermostat also indicates alkaline batteries are required. Product was shipped with two Carbon Batteries made by Kingever. Also the quick reference card that goes into a slot in the thermostat was missing.

Ordered this thermostat to replace a professionally installed thermostat that only lasted a couple of years. I have had good luck with Honeywell products in the past. I have a typical Heat/AC system which has a natural gas fired furnace. I have two separate systems; one for the master bedroom suite which primarily runs at night and one for the rest of the house which primarily runs during the day. This thermostat was for the bedroom suite system. Installation was very straightforward; just a matter of matching the proper color wires with the proper color terminals. Do be certain that you have the power to the system turned off so you will not damage the transformer. After reading other reviews I decided to inactivate the "Smart Response" function. I preferred to have direct control of the system since we primarily use the system only at night. The procedure to inactivate this is very simple and is on page 20 of the Quick Installation Guide. I have been very pleased with the operation of the thermostat. It is easy to setup and keeps the room at a uniform comfortable temperature. UPDATE-Display faded out and became unreadable in less than a year of use -Replaced with "tried and true" Honeywell model RTH2300/RTH221 Series which is all I really needed to start with.

Horrible instructions. No labels on the terminals you figure it out and put them on yourself. Really Honeywell? What a joke! Don't buy this!

I did not work for more than 3 days after installation. Our heating guy that installed the one we had to buy to replace this one said he sees this Honeywell programmable thermostat not work more often than not.

This lasted 3 months before it completely stopped working.

Display was blank. I discarded the old thermostat before realizing the new one was dead. Spent a few days without heat as a result. Wasted some time on the phone with tech support who instructed me how to install aaa batteries. Ordered a replacement hoping it would arrive sooner than another make/model, but it was a day late. Replacement is working now but can I trust it to turn the furnace off before the house sets fire?

I successfully installed this thermostat and it worked just fine. The problem is after all the work installing it, the thermostat will not stay snapped on the back. I'm returning it for a better product. Honeywell usually makes a better product than this. Not attractive when it just hangs on the wall. I tried to contact Honeywell and gave up because of the long wait.

I have a standard central heat/air pump and this does not work on a "multi-stage" system (not sure how I could have determined that prior to trying to install this). Take a peek at your wires before ordering - I had a white wire labeled W2 which made this thermostat incompatible. On a positive note, Honeywell customer service was quick, very helpful and gave me a list of compatible models.

The screen is incredibly small and no option to set/see day. This is not what I ordered but I also paid for installation so I have no choice but to keep it

No backlight - Honeywell customerless service lived down to minimum (a useless phone number

Purchased on 07/19/17,after 2 months the display is blank.Contacted Honeywell and they will send me a replacement. Just hope this one last me more than 2 months!!!

This thermostat has settings throughout the day to auto set the temperature, so you can coordinate usage of cheap time electricity vs exensive time, when you are not home. It seems to have a mind of its own, however. Does not work according to time settings. Didn't notice until too late to return.

This does not turn on automatically when it reaches the temperature I set. When our handyman put back the old one, it worked fine. I called the honeywell but they keep saying I need to have contractor look at the wiring.. do not buy this

Very poor. Works some of the time and not some of the time. Sometimes when it come on it forgets to turn off and your freezing. So you have to turn the thermostat up and next your hot. Not good

Unfortunately this thermostat does not work; even with the assistance of an A/C professional and contacting Honeywell to walk through the steps of installation. I wish to return it to the seller even if a refund will not be given as the item is defective.

This thermostat from "online plumbing" was not new and had been previously opened. It seemed okay anyway and we installed it. The thermostat read too low (when compared with an in-room thermometer) and, after living with it a couple of weeks, we removed it to see if anything was wrong. It was corroded, both on the motherboard and the battery contacts. Doubt it was a problem with the Honeywell product, because we have been very happy with every other Honeywell thermostat we've had.

The positive: Installation was clear, straightforward, and easy. Programming was a snap. Unfortunately, the thermostat is grossly inaccurate in operation. When set to cool, it indicates six-to-seven degrees BELOW what the temperature actually is. I tested this with FOUR different digital thermometers placed nearby, all of which registered this difference within one degree of each other. Obviously the unit is defective, so I'm returning it immediately.

It was easy for the install, and I can program it very easily. I love that I can take it off the wall, sit down to do the programming. I love that it should allow for multiple time changes. BUT After I programmed it, it would NOT adhere to the program. It will only go with time variations of the pre-programmed setup, apparently. I cannot make it work with my power company time of day hours and temperature changes to pre-cool and then stay at high temp. It keeps wanting to cool things down (recover it says) when I need it to stay on 81. . Maybe mine is flawed, I paid someone $100 to install this thing and it's not worth it to pay again to replace.I called customer service, got an "international" call center employee who helped me disable the "recovery feature. Now it works OK but stlil doesn't do exactly what I have programmed it to do, which is: 77 all night until 1 pm then 74 until 4 pm, then 81 until 7 pm then back to 77 again. It just won't do the 77 to 74 to 81 thing no matter what.

AC never worked. I thought my AC broken but repair came and confirmed it was thermostat--but by that time it was too late to return. Quality control anyone?

I purchased this thermostat for my home more than a month ago. The unit always reads 7-8 cooler than what the room temperature actually is. I contacted Honeywell Customer Service and the only responses they gave me were reasons I could get an inaccurate reading which included:"It is not unusual for the displayed temperature on a digital thermostat to read 2-4 degrees different than a standard thermometer. This is because thermostats measure ambient air temperature and radiant wall temperature whereas standard thermometers only measure ambient air temperature. Digital thermostats also round the temperature display in order to provide a more stable temperature display. These factors can account for the 2-4 degree temperature difference between the thermostat and a standard thermometer"All of the troubleshooting was pure speculation, none of which was a factor in the placement of our thermostat. Our old one "that just quit working" had no problems with giving an accurate reading.Terrible customer service for a terrible product. Returning to Amazon, by the way, because the company would not take it back. Their 1 year warranty is backed by the retailer. Not them.
