    It has been a very long time but,

    I'll give it a try. Why not upgrade the stat to something in english and not Lennoxesse?

    I hope:
    R = R
    W = W
    Y = Y
    V = reversing valve
    M = Motor or blower motor

    Put a 3 amp ATO or ATC automotive type fuse in the hot or red side of the low voltage coming off the transformer and then run through the above to see if I am right. Do the same at the air handler and the outdoor unit.

    What I can not remmeber is if the Lennox guys ste the heat pump reversing valve to fail in heat or cool mode.

    Good luck

    Mark
