    wiring a trane with a hunter thermostat
    i have a general electric weathertron thermostat model number 3aat80b1a1 or 2a1 both numbers are listed. I am changing to a digital thermostat but the letters on the old one and my new one are not the same. My new one is a hunter touch screen model 44860 for a 2 stage heating and ac. Can you help me match the wires appropriately.

    the letters on the hunter thermostat are as follows:

    y1
    y2
    w2
    g
    rh
    rc/r
    l
    c
    o
    e
    w1
    b

    the letters and color of attached wires on the weathertron are:
    r = red
    t = brown
    o = orange
    g = green
    y = yellow
    x2 = black
    b = blue
    w = white

    appreciate anyone who can help with this. Kevin
