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Rated 5 out of 5 by to install & program I bought this recently to replace an outdated & un programmable model original to my home.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 1 out of 5 by Fine for about a year This thermostat was easy to install and worked fine for about a year, but recently had started turning on heat in the middle of the night. Woke up to warm house at 2AM, thermostat say "WAKE" and is at 70. Wake time is programmed for 5:45AM... Went through and double checked all programming, and then it happened again. I don't know how many nights have been like this. No wonder my gas bill has been so high... Replacing it with another brand today. February 20, 2014
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 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 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
