    New Honeywell thermostat wiring help w/ Picture
    Old thermostat with the wire on. New thermostat with no wire. Which wires goes where on the new one?

    I have tried:
    C > Blue
    G > Green
    Y > Yellow
    W > White
    R > Red

    Only the heater works. But when on "cool" only the blower is blowing, No cold air.
    But I install the old thermostat all works fine. Does the blue need to go somewhere else?

    Thanks

    Blue wire goes on O/B, white wire goes on AUX and jumpered to E. Yellow goes on Y. Green goes on G. You will need to set up stat for Heat Pump.
