Rated 5.0 out of 5.0 by waltl57 WI-FI Smart Thermostat by Honeywell
Mounting and programming the thermostat was an easy task. I like the idea that you do not have to constantly change batteries. The system has a memory setting, if power goes out, but you MUST have a " C " wire, which, if you do not have, will not make it useful for older homes. Temperature setting takes 1 or 2 days to acquaint itself with the interior of the home, but once it does, it is dead on!

Rated 3.0 out of 5.0 by rp Great thermostat but..
This is an elegant thermostat that works very well. We have had it now for over a year and wish we'd bought three of these.
The "but" is because what you do not want to do is install this in a bedroom. The issue is that it reverses the colors at 2am - we asked Honeywell a year ago to let us change the time it does this but you cannot. If you are a light sleeper, at 2am your room becomes bathed in light. They tell us it does it to protect the screen but it is a major nuisance for us.

This thermostat is easy to use, very accurate and with the app setting it is effortless. When installing, make sure you have the 5 wire conductor in your wall. If you don't you will have to pull a new one. The instructions for using a 4 wire setup don't work, or at least didn't when I set it up. After pulling a 5 wire, it was easy.

Rated 5.0 out of 5.0 by inthedark "C" common wire is a must
bought to replace old temprite thermostat .MUST HAVE "C" WIRE IS A MUST. i choose this one compared to the NEST due to the recommendation of a very good friend who does HVAC repairs and install as a professional. the nest is nice but i didn't like how it just displays the temp unless you scroll to see other settings but this honeywell displays current temp, outside temp, humidity outside and inside, date and time among other things also you can change background color to match decor . it was pretty easy to install just took picture of my old setup of my thermostat and matched the wires , but my C wire wasn't connected so i did find an odd wire wrapped around the other wires which wasn't connected and called my friend who told me to connect it to the thermostat and to go to my furnace and connect the C wire at the motherboard from the furnace the whole insall took about 45 minutes.****BEST FEATURES*** once all set up with wifi i like being able to control temp setting with out being home and being able to control the thermostat with my phone. i can set individual temp setting for each day also has lock out feature which disables the thermostat with a password to keep your settings secure and noone but you can control the temp , has built in alerts in case temp falls or rises past your preferred settings .overall i am 100% satisfied with this thermostat

Rated 4.0 out of 5.0 by hodgy03038 I do love the WIFI Thermostat
It was fairly easy to install it with one exception. The cover on the back left corner didn't want to stay closed and when and if it opened it would disconnect. Nothing a little duct tape couldn't fix. No problems - it works fine and really convenient to set the temp via my phone and now I can actually SEE the thermostat. It was difficult to read the old LCD (black letters on greenish background) where I often times had to use a flashlight to read it. It's fairly expensive though.

Thermostat works well, and pretty happy with its features. However, 9 months after installation the aircon stopped working and after troubleshooting, found out the Y circuit for the aircon doesn't work. Now trying to claim warranty directly with Honeywell.

Rated 5.0 out of 5.0 by gambit77 Honeywell WiFi-Enabled Smart Thermostat
Easily installed in about 15 minutes, intuitive touch screen controls with adjustable color background, indoor and outdoor temperature and humidity, 4 daily setbacks and a great app that runs on your smartphone or computer. The app enables you to remotely turn your unit(s) off and on as well as adjust the temperature and setbacks. If you are replacing an existing thermostat, you will need to connect the "C" wire if it is not in use by your old unit. This involves opening your HVAC unit, going to the terminal strip where the thermostat wires are connected, and making sure that one of the unused wires is connected to the 24v terminal then connecting that same wire to the "C" wire position on the inside of the thermostat. We prefer this thermostat over other brands because of its high ratings from a major product rating magazine as well as the fact that it does not attempt to "learn" our behavior enabling us to have complete control at all times. This is really a great product!!

I have purchased many thermostats in the past with some degree of dissatisfaction. This thermostat holds up to all the hipe. Installation was very easy with no guess work. I was done in 10 minutes including reprogramming to my needs. Installing the the app on my cell phone and laptop was super easy. I would recommend this product to anyone.

Rated 1.0 out of 5.0 by DGinSacCA Worked for a year
I purchased this from HD a little over a year ago. I had the usual issues at first (wifi disconnect etc), but I finally got everything sorted out and it worked great. A few weeks ago the capacitor went out (high voltage circuit, not low voltage which the thermostat is on) on the compressor. I hired a professional to install a new one and after testing we found that the thermostat was out too. I called Honeywell customer service. They walked me through 45 minutes of testing to verify that the unit was the issue. At that point he said, yeah just take your original receipt and return it to HD. What a waste of time and effort. The unit of course it just out of warranty. 1yr

Rated 5.0 out of 5.0 by GeriC Great product!
We purchased this Honeywell thermostat for two reasons: to be able to monitor the temperature when on vacation and because of the fan recirculation feature. My husband would have had to add the "C" wire but with our house layout it was easier for him to run new wiring and relocate the thermostat. The installation went quickly and once installed he left it to me to do the set up. It only took a few minutes to do this thanks to the guided steps. We have been using the thermostat for about 10 days now and love it. We haven't had any issues with wifi connectivity and if you want to override the programmed settings, it's very easy. We are very happy with our purchase and highly recommend this thermostat.

Rated 5.0 out of 5.0 by Warpedscout Works if you research it
Only thing I had to call about was a power wire that support helped find and connect. Had this on my home since October 2013. Someone here said it did not have an automatic mode, it does. Set to automatic And fan preference, select heat and cool points and walk away. Phone app easy to use and works anywhere I have cell service. Read the manual and is easy to install and operate. Have had no problems with this product! Only problems I have seen is users do not research product to their system and either read installation instructions or have a professional (or kid that is technically competent) install it!

Rated 2.0 out of 5.0 by PaulM Good thermostat with issue, don't buy if you are using for home automation!
If Honeywell would just release and API for their products then I would easily give this 5 stars. The most unfortunate problem with this thermostat is Honeywells lack of wanting to work with other developers. They want you to use their web app and phone apps and that is it. Every time someone figures out how to link it, Honeywell breaks the link. If your plan is to use this with a Vera or other home controller, look elsewhere. The 3m50 and 3m80 are good units that work with home automation. I started with the 3m50 and swapped out to this one because of the ease of use. Unfortunately, when I found out that it would not work with my Vera I returned it.
As for the thermostat alone. The touchscreen is nice, It is very bright even at its' lowest setting. Still casts light into the bedrooms from the hallway. If you are placing this in an area with a lot of light, it will be easily seen.
My biggest complaint about the actual thermostat is that it only has a 1 degree swing. If you set it for 75 deg it will remain there until it hits 74 then turns off. At 76 it turns back on. I have found that this is using much more electricity then the 3m50 with its 3 deg swing as the AC is only off for about 5 min at a time. I spoke to Honeywell and they confirmed this is by design. BTW, don't test the actual temp on the thermostat against anything else as they won't match. This thermostat uses their proprietary temp algorithms that measure temp and humidity to give you a "real feel" temp.
In the end, if you are looking for an easy to use touchscreen thermostat that is less energy efficient than just about any other but will provide you with the best comfort levels, this is the one!
If you are looking for something you can control via home automation that is not as easy to control and is much more energy efficient then look at the Filtrate 3m50 instead.

Rated 3.0 out of 5.0 by JAM Requires too much personal information
It was easy enough to install and register, but there is no need for the detailed personal information required to get access to my thermostat over the internet. Otherwise I would have given it a better rating. There is no need for an exact street address (which Honeywell requires!) and many of the required "security" questions attempt to eke out more personal information.

Rated 5.0 out of 5.0 by 1MarcD Very Nice Product, March 13, 2015
Followed Quick Start Guide, and within 30 minutes thermostat was up and running. Followed all the prompts. Within no time of loading thermostat's Mac address and ID, it found my network. Typed in my p/w I was able to communicate with their app. No hitches for me. Scheduling was straight forward with the option to choose help if needed. Outside temp is a nice feature. Thermostat did an update with no hick ups. I was able to match my decor as well. Many options to use if needed, and easy to get to them. Honeywell did very well with this thermostat and instructions. Hopefully one day they will be able to control modulating furnaces.
Note 1: this thermostat was offered cheaper at a competitor. The staff at Home Depot were more than happy to match the price plus give an additional 10% off after verifying it. Saved me an hour and half driving. Great purchasing experience at my local Home Depot.
Note 2: if you purchase this thermostat and a few others carried at Home Depot, Hydro One will also give a rebate of $100 if purchased before March 27, 2015.

Rated 5.0 out of 5.0 by Cshoes Recirc function did the trick
I helped my Father-in-Law select a thermostat that has the Recirc feature into a summer condo. The condo construction is a bit odd in that there isn't any ductwork. The funrace/A/C blower sends air into the crawlspace and the air comes up the floor registers. After spending a ton of money on encapsulation of the crawlspace to honor the warranty terms air needed to be circulated. Since they only live there part of the year (didn't even go there last summer) the thermostat would be set for minimum utility use when they are not there thus less circulation. The recirc feature on this product has dine the trick. Upon inspection of the crawlspace and the overall air quality we are very satisfied. The only negative I see is there is some complexity that we didn't need and had to pay for. No one cares that you can change the color of the display in our case. Frankly we'd be even more happy if it was as simple as Fan on/auto/recirc on a manual switch. When shopping we could not find this simple an offering so settled for this one.

Rated 1.0 out of 5.0 by MellyMel Poor quality and customer service.
Installed on a 3 wire heat (gas furnace only) system. It was easy to install and setup and after some searching their website did recommend installed the "G" wire on the "C" terminal at both ends.
After 4 hours the thermostat shut off completely and had to be pulled off, pushed onto the mount to reboot (or reset the circuit breaker). It came up, ran for a few hours then died again, permanently. No way to revive it. Attempted to call customer service but after 30 minutes on hold gave up.
This was an online order from Home Depot and the local store was happy to refund the cost so I could buy a Nest thermostat.

Rated 1.0 out of 5.0 by Jay NOT SUCH A SMART BUY!!!
Customer service for Honeywell was horrible to begin. No answers to my questions but doing some research and reading reviews my superstition was verified. The thermostat tries to maintain the set temperature with very small difference in temperature possibly less than 1/2 a degree. This causes my A/C to cycle on and off way too frequently. Since installing this thermostat, the A/C will cycle on and off an average 10-12 times per hour during the day and 6-8 times during the night. Talk about wasting energy!
Ideally the temperature Span or Differential setting with the factory default setting being +-1 degree before cycling as most thermostats. Honeywell knowing this has yet to correct the issue. If this thermostat was made with the intent to save energy I think it has failed. I will try to return the thermostat asap but I bought about a year ago but just installed it because my house was under construction. What a mistake in purchasing!

Rated 1.0 out of 5.0 by Marcopolo Not sure if it is a Honeywell problem or a Home Depot problem
I bought this product. It was missing the back plate and had registration for two unit in the box. Exchanged the unit and the new one is deffective. It will not find any wifi network. Again I am not sure if it is a Honeywell problem or Home Depot problem........Contacted Honeywell and they blamed it on my Internet provider......It does not see any wifi from my hotspot or my neighbor wifi that all my other devices see.
Maybe I got two units that were returned to Home Depot and we're just restocked or maybe the problem is with Honeywell......Just don't know

Rated 5.0 out of 5.0 by Jobi Had the Honeywell RTH9580WF 2 Months
I had a new HVAC installed along with the Honeywell Wi-Wi Smart RTH9580WF Thermostat in early June by a HVAC contractor. I registered on the Honeywell site and added the App to mine and my wife's IPhones. Thus far, Absolutely Great! When we depart on trips, we turn up the temp and about an hour out from returning home, we return it to our normal cool temperature from the IPhone. Arrive in comfort... & SAVE MONEY. No more getting up to adjust temp. up or down at home, just pick up the IPhone and make the adjustment. Convenience all around. I was skeptical about losing my Wi-Fi connection & having to reset but so far no problems. Lost our electricity twice for short brief periods during some southern thunderstorms but as soon as the electricity came back on and the router was back up; so was the thermostat. We love it , hope it stays that way!

Rated 1.0 out of 5.0 by GoDarkBrightly Design issue regarding screen protective mode
Found the thermostat to be very competitive. I formerly used competitors thermostats in my CA home but selected the Honeywell as I found our household's non-traditional and variable schedule did not lend itself to a learned programming approach. The instillation of the product was textbook and when installed in a bedroom the selection of a coordinating and subdued color screen along with reduced backlight settings were just perfect for a tranquil sleeping environment. THEN 2AM, the screen automatically goes in to a screen preservation mode which overrides these settings and floods the room in stark bright light. A screen saver that goes bright not dark. Solution get up, touch screen to the Home button and wait for the screen to resume your program settings. Oh, manufacture says no design flaw intentionally programed that way with no cancel option or time variable on screen saver option. If you don't sleep between 2am and 3am should work for you.

Rated 5.0 out of 5.0 by CSelil Simple, Functional, & Attractive
Installation was SOMEWHAT easy. Apparently it is VERY easy to short out the connecting wires (assuming you're installing this yourself). Other than that, following the provided installation videos, everything was very straightforward. The device itself is very attractive. It's large enough to be easy to read and operate, but not so large that it's taking up a large amount of wall space. Set up was very easy. Operation is VERY easy. It's very nice that I can use the app to control the a/c as well. Ultimate laziness ensues when I'm downstairs reading on my iPad and want to turn the a/c down. Why walk up the stairs when I can just hit a couple buttons on my iPad. Overall I'm very pleased with this product. Only note: make sure you don't allow your "C" chord touch *anything* as you could short it out and have to replace a fuse.
