Programmable thermostats can mean big savings during summer
In the summer, save money by automatically turning up the air conditioner at night or when you’re away from home.
You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting. (If you have a heat pump, don’t do this without a programmable thermostat).
You can do this automatically by using a programmable thermostat and scheduling the times you turn on the heating or air conditioning.
As a result, the equipment doesn’t operate as much when you are asleep or not at home.
Programmable thermostats can store 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.
