    Wiring problem from White Rodgers to Honeywell
    The Old White Rodgers 1F59-11

    W - White
    R - Red
    C- Blue
    G - Green
    O - Brown
    Y - Yellow
    Orange wire not used

    The New Honeywell RTH7400 has

    -------Conventional--------
    ------------- Heat Pump---------------
    C C w2 Aux
    G G y2 E
    Y Y L
    O/B W
    R Jumpered
    RC Together


    The G, Y, R, C, all seem obvious, and I thought the W would go to the white wire but that leaves the brown wire that was hooked up to the old O. The white and brown wouldn't go together would they?

    Thanks
