Remove Your Old Thermostat

  1. Before installing the new thermostat it is a good idea to verify all heating and cooling stages for the existing HVAC equipment are working correctly.
  2. Disconnect power to the HVAC equipment before starting to avoid risk of electrical shock.
  3. Remove the old thermostat cover. Some will pop off, but others may have screws or snaps to hold it on.
  4. Take a picture of the old thermostat wiring before you change anything.
  5. Label each of the wires with the letter of the terminal they are connected to on the old thermostat.
    • Make a note if there are any jumpers on the thermostat connecting 2 wires together (for example Rh and Rc).
  6. Disconnect the wires and remove the old thermostat from the wall.
