Did you know that properly using a programmable thermostat in your home is one of
the easiest ways you can save energy, money, and help fight global warming? An
ENERGY STAR qualified 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 asleep or away.

The average household spends more than $2,200 a year on energy bills — nearly half
of which goes to heating and cooling. Homeowners can save about $180 a year by
properly setting their programmable thermostats and maintaining those settings. The
pre-programmed settings that come with ENERGY STAR qualified 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 ENERGY STAR Programmable Thermostat Calculator to see what you can save
with set-back temperatures that work for your family. The pre-programmed settings for
an ENERGY STAR qualified programmable thermostat are:
