You can save as much as 10% a year on your heating and cooling bills

by simply turning your thermostat back 10% to 15% for 8 hours. You

can do this automatically without sacrificing comfort by installing an

automatic setback or programmable thermostat.

Using a programmable thermostat, you can adjust the times you turn

on the heating or air-conditioning according to a pre-set schedule. As a

result, the equipment doesn’t operate as much when you are asleep or

when the house or part of the house is not occupied.

Programmable thermostats can store and repeat multiple daily settings

(six or more temperature settings a day) that you can manually

override without affecting the rest of the daily or weekly program.
