Rated 4.4 out of 5 by 38 reviewers.
Rated 5 out of 5 by wonderful choice! After having a kitchen and bathroom remodel, I realized that I needed to replace my old thermostat in the house. The one I replaced was original to the house, so the system was approximately 40 years old. Concerned about the compatibility, I chose to go with the non-programmable unit from Honeywell. I had been told that their systems would work with most older systems. I have been extremely pleased with the result of my choice. It took only about 45 minutes for me to install this unit, and I am just a DIYer with minimal electrical experience. I love the fact that it does NOT have all the bells and whistles. It shows the current temperature of the house, but when you decide to raise or lower the temp, it immediately shows what the thermostat is set to and what you are setting it at. I have had no problems with it handling my old wiring. I'm very pleased with this unit. January 11, 2014
Rated 5 out of 5 by Very nice replacement thermostat Came with installation documents that were easy to follow. Small wire marking stickers are a nice touch. You just check to what your letters connector your old wires are connected (they are marked like R, W, RC , etc) and put sicker on the wires so you don't get mixed up. Note the orientation of the device. My old one was the same dimensions, but vertical, so I'll be putting a couple more holes in the wall, but that is fine. Simple product that works for me, I only need the heat setting, so can't attest to the cooling setting. April 24, 2013
Rated 5 out of 5 by Fantastic option for old HVAC unit I purchased this unit to replace an old analog thermostat on a 1986 Lennox HVAC. I was informed, when unit was checked by Home Depot at home services rep, that the back up heat had been by-passed so that anytime heat was called, the back-up strips were on. Understanding this much, I did determine I could upgrade to this digital thermostat which did not involve back-up heat. I did have to consult with Honeywell and the third individual I contacted was able to decipher the correct wiring. Unit is fully operational and I am 100% satisified with this purchase. Due to the conversion, the install was somewhat diffcult. December 2, 2014
Rated 1 out of 5 by Not Durable This unit had the limited functions I desired, and was reasonably priced. It was easy to install in place of the old manual thermostat. The trouble was that it functioned properly for only about 6 months. At that point it would no longer turned on the gas fireplace. I could bypass / jump the thermostat and the fireplace would turn on, and it would turn off when the room temp exceeded the set point. However, it would not turn on the gas again when the room temperature dropped. I replaced it with the same Honeywell thermostat and again, after about 6-8 months, the thermostat failed in the same manner. December 3, 2014
Rated 5 out of 5 by Easy Install It was very easy to install and configure this thermostat. I don't need programmming functions because we have radiant heat and keep the temperature a constant value. I bought this thermostat to to replace one that only allowed setting the temperature and nothing to display the current temperature. At the time, figured it was unnecessary. However, when your heating system fails, you need to know how close you're getting to freezing pipes! The profile is shallow .... it's not any thicker than the nearby door trim. That's a nicer feature than the thermostat it replaced too. January 18, 2014
