CUSTOMER REVIEWS

Rated 3.9 out of 5 by 22 reviewers.
Rated 4.0 out of 5.0 by good thermostat, programming a challenge The thermostat works just fine. We have a lot of Honeywells throughout our facilities. This particular one was purchased because of the auto heat/cool. Initially the auto feature was not appearing for heat/cool. You need to go into the advanced setup menu to access feature 12, then set it to auto switchover. The manual does explain this in the advanced setup section. It is very easy to do, but the thermostat did not come with this feature already enabled. That was probably a poor, but necessary choice on Honeywell's part. I would purchase this product again and recommend it to others. Just be prepared to do some more programming than you may have been used to. May 16, 2014
Rated 5.0 out of 5.0 by As Advertised: Easy Install Simple install with our furnace/air system. The install instructions were simple, concise, and yet detailed enough to make install a breeze. It powered right up and functioned perfectly. One piece of advice. For securing the thermostat wires to the terminals on the unit you need a very tiny flat head screwdriver. I happened to have a set of precision screw drivers, but if I hadn't it would have meant another trip to the store. It also does NOT come with the 2-AA batteries required for operation, so make sure you have those on hand. I thought the batteries were only for memory in case the power goes out, but the furnace cable does not power this unit. July 23, 2011
Rated 5.0 out of 5.0 by HVAC Thermostat I bought this for my parents house, their old thermostat was blown by a lightning strike to the house. Simple to wire, just match the wire colors and connect. The new thermostat is easy for them to use. They love the comfort improvement over the old thermostat that was also electronic. This thermostat holds the house within 1 degree and so far they have had no need to bump it up or down. They say the house is more comfortable than it has ever been. July 12, 2012
Rated 4.0 out of 5.0 by Very Good Thermostat I purchased this item for a rental property and the tenant said that it is easy to program and works well. March 29, 2015
Rated 2.0 out of 5.0 by Good but has an installation issue Price was good. However after I installed it found the heat would not work. After removing the faceplate found one of the middle prongs in back was bent. Broke when I tried to carefully straighten it. Now I have to but a new one. Had installed for just two weeks. Why make something where this can happen? I was careful but could this could happen to anyone. Liked the performance of this thermostat but not so sure I will buy another because same thing can happen. Called Honeywell and told too bad. October 13, 2014
