  What If There Is No C-Wire?

If you do not have the C wire, you can try to do as follows, but please confirm with your HVAC manufacturer or the electric engineer firstly.
1. Furnace Part: Put Gwire connect to C terminal, use the black jumper wire connect G and Y or W (if you need heat, connect to W, otherwise connect to Y)
2. Thermostat Part: Connect G wire to C terminal on the wallplate. G terminal on the wallplate is blank.



Vine thermostats typically work without a common ("C") wire.
The Vine power connector is an easy C-wire replacement if needed.
