What If There Is No C-Wire? If you do not have the C-wire, you can attempt the following steps, but it is crucial to confirm with your HVAC manufacturer or an electrical engineer first.

1. Furnace Part: Connect the G-wire to the C terminal, then use a black jumper wire to connect the G and Y terminals (or the W terminal if you require heating; otherwise, connect to Y).

2. Thermostat Part: Connect the G-wire to the C terminal on the wall plate. The G terminal on the wall plate should be left blank.
