    RTH8580WF Can I substitute C wire with G wire?

    I have a 25 year old Carrier central AC with electrical baseboard heaters with no fans in the baseboards. Everything is electrical, there is no gas or propane, or heat pump. There is no other source of heat aside from the baseboards.

    The current thermostat is mechanical. The options on it are Fan : Automatic or On. Temperature: Heat, Cool or Off.




    I'm trying to install the RTH8580WF Honeywell WiFi Thermostat but I have no common wire. Can I use my G wire instead of the C wire?

    The thermostat controls the baseboard heaters?
