    Prog thermostat wiring
    I am installing a programmable thermostat (upgrading from a previous programmable that wasn't to our liking.

    When taking the old thermostat I labeled 5 wires HOWEVER, I'm not sure which to use for RC and RH or if this changes all connections
    My new thermostat requires:
    RC
    RH
    G
    Y
    W

    The wires from the wall are:
    G - green
    C - aqua
    R- red
    Y-yellow
    W-white


    So, I need to "map" the wires
    Can anyone help me? I am at a loss here. The house is about 4 years old. If I can't get an answer here (or how to TEST which wires are what),
