    wiring a new thermostat
    I'm trying to wire a new thermostat to my ancient heatpump but I'm not sure where the wires go exactly since the old coding is so different than the new new coding.

    Old coding:
    Wire color - location - my guess to new location
    Green - G - G
    Red - R - Rh
    Brown - B - W/B
    Yellow - Y - Y/O
    Blue - X -??
    White - W2 and E -??

    please, someone help me!
