Wiring Nest Thermostat

Can someone tell me how to identify which wire is for heating?  I have a gas furnace and no heat pump.

Hi LindaTiller,

 

Thanks for posting a picture of your wiring, that always speeds up identification. With your system, your Rc wire is handling both the heat and the cooling power. We have a common wire identification chart that you can see here: https://goo.gle/3ct9L9n. You will see an explanation for all of your wires there. If you have any other questions, please let me know.

 

Thanks,

Jeff
