  1. I have a communicating module (Vg and V+)
    Have AC/Furnace/Humidifier, connected to the communicating module.
    Trying to replace the non smart thermostat with a honeywell smart wifi TSTAT
    Can i connect C wire to V+ to power up the new smart thermostat?

    1. Hi Gopal! I am very sorry, that I am not familiar with the thermostat you have and I am not familiar with the Honeywell thermostat that you are installing. I can only suggest that you read the thermostat instructions or call Honeywell customer support to find out the answer. Steve
