Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Long term savings This thermostat has been great. Programmable section is the best. Up to 7 setting for each day. Great for increasing the heat an hour or two before getting out of bed in the morning when it's cold. The Economy feature button is an excellent feature on those days when you don't feel you need the a/c on or the heat to come on and an auto adjust up or down 4 degrees without having to turn the unit off. It is connectable to a wireless module monitor your power consumption when away and adjust the temp on a cell phone or portable device. February 19, 2014
