Rated 5 out of 5 by Edward37 This thermostas system simply replaced the same place where the previous thermastate was for easy access. We really do have nice cooling and temperature control just recently instatalled. August 18, 2014
Rated 1 out of 5 by Granny55 Does not do enough! Yes it controls zones. Yes you can control from your phone. No it does not give the simplest control for different times of day. July 31, 2014

Rated 1 out of 5 by KeithDVR VERY basic is the best I can say I will also point out it that it is very loud. This is what was included with my A/C Heat Pump installation. I would say not to waste your time and money on this product. Get a good one from the start. IMO Lennox should dump this model. April 19, 2013
Rated 1 out of 5 by soppen Loud and unrelialable I will second the other comment that when switching on the furnace it makes a very loud click. We have also had trouble with the thermostat intermittently not starting the furnace and then thinking it is running. This results in no heat until the controller is reduced below current temperature and then re-raised. I will be replacing this product as soon as possible. January 27, 2013
Rated 1 out of 5 by rainy This product should be sound proof. This product makes such a loud clicking noise before coming on and when going off. It was so bothersome I went back to my oldie goldie thermostat with the slide lever. Too bad as seeing the temperature numbers was a bonus but not enough to listen to that on and off clicking.
