- Identify the terminal on the thermostat that requires an additional wire.
- Run a new wire from the HVAC system to the thermostat location.
- Connect the new wire to the appropriate terminal on both the HVAC system and the thermostat.
- Turn the power back on and test the thermostat to ensure it is functioning correctly.
