Keeps you comfortable by automatically calculating exactly when the furnace or air conditioning
should go on to have the house at the desired comfort temperature at the time you want.
Saves the maximum amount of energy and money by remembering to automatically set back the
heat or air conditioning when you leave home or sleep.
Provides the ultimate in comfort and convenience . It comes already programmed, so it's your
choice—use the pre-programmed schedule or set your own.
