Rated 3.4 out of 5 by 27 reviewers.
Rated 5 out of 5 by to install & program I bought this recently to replace an outdated & un programmable model original to my home. The directions said I'd be able to install in less than 15 minutes and to be honest, it probably took less. It's very straightforward and simple to do my 9 yr. old daughter could easily manage this. Once installed it's very simple to program the temps you want to keep throughout the day. Great buy! September 17, 2013
Rated 3 out of 5 by second one works great i can only rate it at three stars since the first one i purchased was defective out of the box. returned it and the second one works just fine. it is rediculously easy to install (if you know how to use a phillips screwdriver you can install it) and outside of the return trip it only took about 5-10 minutes to install. if you read the manual it tells step by step how to program. it's a simple to use and install thermostat.

Rated 3 out of 5 by Ok. 7 day program is not separate for heating and cooling. has to be reprogrammed for each change of heating/cooling season. expected a little more from honeywell. February 3, 2014
Rated 5 out of 5 by Extremely Easy and simple I had an old thermostat that I replaced with this one. I thought it was going to be a mess to program because the wires from the old one didn't match up with the new one. I called the customer service number in the manual and they actually were able to tell me exactly how to hook it up, which I was suprised at. Once I figured the wiring out with their help, it only took about 5 minutes to hook up and program. February 17, 2012
Rated 4 out of 5 by Nice back lit display on a 7 day t-stat Installed this Honeywell 7 day programmable thermostat three days ago in place of a 5-2 programmable t-stat. Installation was simple with easy to understand instructions. The t-stat has been working as expected. Pros: Simple installation Back lit display turns on for 12 seconds when a button is pushed. Good for adjustments at night when the lights are off. 4 programming periods for seven separate days of the week. Keeps accurate time and temperature readings. Inexpensive Can turn off adaptive intelligent recovery function. Cons: Dead band control (amount of over and under shooting target temperature) is unintuitive. Setup uses number of heating cycles per hour? Runs on (2) AAA batteries. Won't last as long as my old t-stat that used (2) AA batteries. Overall, a very good 7 day programmable thermostat at a good price. January 25, 2010
