Rated 4.5 out of 5 by 36 reviewers.
Rated 5 out of 5 by Easy installation, tips The directions were easy to follow and the unit easy to install. Three tips: 1 the directions don��t explain how to separate the thermostat from the wall plate. It pulls apart, just grab each and pull. 2 The screws that hold the wires down are very small. Before you start be sure you have a screw driver that will fit. 3 It uses two AA batteries as backup power but they are not included. I would recommend and buy this thermostat again.

Rated 4 out of 5 by Okay for the most except The thermostat is pretty decent, works well so far, only there is one thing I would change about it. Anytime you want to set multiple schedules for select days, you have to push "Save" after each set schedule, and then start over again to set the next schedule. Thus, what I would change is, after saving a schedule, the unit should remain in Edit mode, so you can select other days for the next schedule. And then once you are completely finished setting and saving all your schedules, there should be a "Done" or "Finished" button that will take you out of "Edit/Schedule" mode. December 13, 2011
Rated 5 out of 5 by Nice Product....Easy Update THE UPS…. Very nice thermostat Easy to install Looks nice on the wall Backlighting is easy to see and easy on the eyes at night It’s a Honeywell THE DOWNS The users manual is a little tricky when configuring thermostat My recommendations Make sure that you know as much about your heating and cooling systems as possible BEFORE switching out your thermostats, read through programming section once you DO know and circle your codes so you can breeze through set-up and make sure that you use the provided labels to tag the wires BEFORE unhooking them. I took a picture with my camera and printed it out and taped it to the wall as a reference. It comes preset with energy star ratings to save you money I left my alone and I guess I will check the gas and power bill next month to see the savings. I installed this model a few years back in my mom’s house and she has had 5 years of trouble free use with it. It is compatible with most all types of heating and cooling systems but if you need help call the 1-800 number and the staff at Honeywell will be ready to help you out. April 5, 2010
Rated 5 out of 5 by Easy to Install, Tricky to Program I have a heat pump/furnace combination. They take you step by step marking the wires coming out of the old thermostat, so installation is easy...a very small screw driver (for the heads of the wire terminals), regular screw driver for two mounting screws, hammer (for plastic screw holders),wire cutters (if you need to clean up the old wire), and drill with 3/16 or 3/32 inch bit depending on wall type. For simple installations, the programming is super easy. For more complicated AC/Furnace combinations there are 'functions' that need to be programmed into the thermostat. I ended up calling the 800 number and they led we through have to press a button twice (where the instructions indicate once) and hold of of them down longer than the five seconds the instructions indicated to get the function screen to come up. From there on, it was pretty easy. The Honeywell call center was, knew the answer quickly, etc. Operation of the unit is very good. July 14, 2010
Rated 5 out of 5 by Does exactly what it is supposed to Our old thermostat was attached with duck tape. Having rambunctious cats around, I was in constant fear of them breaking it and getting mercury poisoning, so I was very determined to replace our thermostat. If you want to do it yourself, please follow instructions carefully and make sure to carefully mark all your wires. We made that mistake and ended up having to bring in a professional to install it. But that's our fault, not the fault of the thermostat. Once we got it installed, it works fantastic. It's nice to be able to set the house to the exact temp. we want, not to have that "fiddle room" you get with the old fashioned thermostats. It looks nice on the wall too, rather than some clumsy dial or box. The timers work perfectly, and it's nice not having to remember to set the heat up or down at certain times. We have it set to go low at night and then to go up about an hour before we wake up, so no more, "I don't wanna get up, it's too cold out there!" We couldn't be more pleased with the unit.
