    Replace Weathertron thermostat with Honeywell RTH3100C
    I am replacing my Weathertron BAY28x138A thermostat with a Honeywell RTH 3100C thermostat. It is on a Trane XL1200 Heat Pump with Aux. and Emerg. Heat. The terminals and colors of wire are as follows on the Weathertron:

    O-Orange
    R_Red
    T-Brown
    G-Green
    Y-Yellow
    X2-Black
    B-Blue
    U-Jumper to W
    W-White
    F-Blank

    The terminals on the Honeywell RTH3100C are as follows:
    E, Aux, Y, G, O, L, R, B, C.

    I could use help in determining which wire to hook to what and as near as I can tell the T-Brown is not used on the new thermostat.
