How to Convert From a White Rodgers Thermostat to a Honeywell

Julie Boleware

The U.S. Department of Energy recommends a programmable thermostat for heating and cooling efficiency. Programmable thermostats allow the user to program different room temperatures for different times of the day. Features like this give the consumer more flexibility because he can set certain hours of the day or night to a specific temperature. The U.S. Department of Energy says dropping the temperature 10 to 15 degrees for 8 hours will save about 10 percent in yearly energy costs.

Installing a thermostat can be done in less than an hour.
  1. Turn off the air handler's power off at the breaker box.

  2. Take off the top of the White Rodgers thermostat. Remove and label each wire on the old subbase (bottom part screwed to wall) with the code on the terminal the wire comes out of.

  3. Unscrew and remove the subbase.

  4. Mount the new Honeywell thermostat subbase.

  5. Connect the wires according to the labels on the Honeywell subbase.

  6. Press the thermostat onto the subbase (it should snap on).
