Hi everyone! I recently bought a new home. It has four zones for heat and one zone (entire house) for air conditioning. The air conditioning is on its own wiring. The wires for air are Rc, Y, and G. Coming from the wall, Rc is a red wire, Y is a white wire, and G is a green wire. For my Ecobee 3 Lite, can I just substitute the G for C and lose the fan functionality? Will that mess up my system or cause any electrical problems? Thanks!
