I bought a wifi thermostat and tried to use G instead of C since that's what the manufacture suggested if no C. Was able to on the thermostat end but how do I add it on cooling/heating system end. Picture attached. Any help appreciated. I could not find the circuit.

We need photos of the wiring at the system end, and a good shot of the wiring diagram if you can get htat – ThreePhaseEel Oct 16 '16 at 22:09
It looks like you have a boiler, which means zone valves and/or zone controllers. We'll have to know about all the equipment involved (including zone valves, etc). – Tester101 Oct 16 '16 at 23:01
