Rated 4.3 out of 5 by 60 reviewers.
Rated 5.0 out of 5.0 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 5.0 out of 5.0 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 5.0 out of 5.0 by Basic Furnace Control I'm a believer in the "KISS" principle (Keep It Simple Stupid). With all the internet hacking going on these days the last thing I wanted was to come home some day with my furnace going full tilt. This thermostat is about as basic as they get. No internal clock to set, no programming to mess with, no internet connection. It will control heat or cooling with a minimal amount of internal wire connections and control setting... just what I wanted. Battery replacement is simple, just pull from the bottom and the front flips up for battery access. Two screws mount the back plate to the wall and the clips for the front panel hold it firmly in place. Included installation and operating instructions were clear. For a retired I.T. geek & database application project developer, this was perfect! November 4, 2015
Rated 4.0 out of 5.0 by Thermostat This Honeywell non- programmable product is easy to install. November 3, 2015
Rated 5.0 out of 5.0 by Easy to Install Thermostat This product was very easy to install. I was surprised at the ease of doing it myself! August 11, 2015
Rated 5.0 out of 5.0 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
Rated 5.0 out of 5.0 by Simple Installation The product instructions claimed this was a snap to install and it was!! It took 10 minutes tops. My husband was so proud. August 26, 2015
Rated 5.0 out of 5.0 A timely order We're redecorating our living room and I decided to replace everything, including the thermostat. The wife didn't want a programmable one and the one we currently have was a honeywell, so it was a no-brainer. I was going to replace it after painting but the old one died (thermostat, not wife) and I had to install the new one. Easy installation, works great. June 18, 2013
