A simple thermostat with smart features

Why make things more complicated than they need be? Our 5-2 Day Programmable Thermostat excels at simplicity, convenience and comfort. It starts with the backlit display that’s easy to read in dimly lit areas. It continues with the way you program it — one program for the week, one for the weekend. That kind of programming saves on energy costs — as much as 30%. Then there are other nice features, such as the filter reminder and Early Start, that ensure the scheduled temperature is reached at the programmed time.
