- 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.
- Disconnect power to the HVAC equipment before starting to avoid risk of electrical shock.
- Remove the old thermostat cover. Some will pop off, but others may have screws or snaps to hold it on.
- Take a picture of the old thermostat wiring before you change anything.
- 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).
- Disconnect the wires and remove the old thermostat from the wall.
