    Connecting an old Honeywell to a Hunter 44660
    I want to replace my old Honeywell thermostat with a Hunter 44660 programmable thermostat but I am having problems connecting the wires. The codes on the old theromast do not match up with the codes on the new one.

    Old thermostate codes
    G=Green
    C=Black
    R=Pink
    Y=Yellow
    E=White
    WZ=Blue
    O=Orange

    The connectors on the new progamable thermostat are

    Y1
    RH
    RC1
    RC
    Y/O
    W/B
    G

    Which wires from the old thermostat go to the new connectors on the new thermostate
