Rated 4.2 out of 5 by 107 reviewers.
Rated 5 out of 5 by Easy to Install and Lower bills already As a new homeowner, I was anxious to reduce my cooling bill and decided to install a programmable thermostat. Having never done home maintenance before, I was somewhat worried that this would be difficult and I would need to hire a professional. This product, exactly as promised, installed in a minimum amount of time with the effort of a novice. The instructions are easy to read and follow. I have already seen a slight difference in my power usage also. **Hint: Make sure you have a very small screwdriver as the screws are tiny. I had to use an Exacto knife. September 2, 2014
Rated 5 out of 5 by I enjoy this thermostat When I went away for few days I always set my thermostat around 45F just to keep water in baseboards moving. The problem was when I returned home, it took few hours to warm up my room to feel nice and toasty. This thermostat was the solution. I checked on internet several videos to learn how to install it and just got confused with all wiring involved. When I finally started working on this project, after removing top of old thermostat I learned, that I will deal with two wires only. What a relief! My home is heated by hot water baseboards and oil furnace. No fans, no heat pump, no AC - simple. But this thermostat can handle much more complicated system. Installation actually was not as difficult as I expected it to be.Temperatures can be set in Celsius and Fahrenheit degrees. Now when I go away I program my new thermostat to higher temperature for several hours before my return and I am enjoying my coming back home much more. This thermostat comes with labeling stickers for indicating any single wire, "Quick Installation Guide" booklet and "Operating Manual" booklet. December 30, 2013
Rated 5 out of 5 by Headache Saver! This thermostat intrigued me, because of its simplicity. I got tired of being the only one in the house that ‘knew’ how to set the 7-day programmable thermostat we had. This new Honeywell uses only 2 types of settings. This thermostat has one setting for the ‘5 weekdays’, and one setting for the ‘2 weekend' days. Those are the only options most of us need, and this unit is interactive. Anyone can set the time to wake the heat or cool cycles and when they need to be off for work or school. Then it will turn the heat or A/C on again, before returning home. Finally it will hold your desired sleep temperature, for the night. Everyone can follow the screens and have the adjustments needed. Compatible with multiple systems with settings for Gas or Oil and Electric heat/AC or heat pump systems. April 24, 2013
Rated 5 out of 5 by This product is very simple to instll and has eveything you need. I have had this product for only a couple pf weeks and I am more than satisfied. It has all the features that I need and it was very simple to install. It has features for wveryday of the week and for four different times during each day. In addition, it lets you know when to change the a/c filter and has a light for when you want to change a setting at night. February 11, 2014
Rated 5 out of 5 by Easy to install, use, and very accurate temperature control This thermostat is perfect size and so easy to install. It also has two different temperature settings that we currently use for a day setting and night setting when we go to sleep. All of the rooms in our home have all been the exact same temperature since we installed it, which was not the case with our old thermostat. It's also very easy to program and understand so changing temperature settings is super easy. April 28, 2013
