Control the temperature
in your home automatically.

A programmable thermostat automatically changes the temperature in your home for sleeping and waking hours. It also can deliver different temperatures when you're away.

There are many options to choose from. Some control heat only, and some also control air-conditioning. Some can be completely programmed in one sitting; others require a week-long run-through.

When shopping for a new thermostat, bring along the brand name and model number of your old thermostat and the heating and air-conditioning units to make sure they'll be compatible. Here are guidelines for installation, but follow the manufacturer's instructions that come with the unit.

 

As you remove wires from the old thermostat, label them. Remove the old thermostat. Pull the wires through the new wall plate, and mount the plate securely to the wall. Check that it is level. Push any excess wire back into the wall and hook up the wires according to the manufacturer's instructions.

Attach the body to the cover plate. Set the clock and program the unit according to the manufacturer's instructions. Attach the cover.
