A programmable thermostat helps make it easy for you to save by offering four pre-programmed settings to regulate your home's temperature in both summer and winter - when you are home, asleep, or away.

The pre-programmed settings that come with programmable thermostats are intended to deliver savings without sacrificing comfort. Depending on your family's schedule, you can see significant savings by sticking with those settings or adjust them as appropriate for your family.

The key is to establish a program that automatically reduces heating and cooling in your home when you don't need as much. Use the programmable thermostat calculator to see what you can save with set-back temperatures that work for your family.
