    old 7 wire t-stat
    Hello,

    I went the whole winter without heat and I'm selling my house soon so I figure now would be a great time to replace the broken T-stat... all I know about my heat/air is it is all electric... this is the old setup

    white = W2
    brown = E
    Orange = O
    yellow = Y
    RE = R
    black = C
    green = G

    My goal is to replace the old digital one with a new inexpensive digital one

    I will gladly any questions... please tell me what to do... Home Depot is no help at all.

    You will need a thermostat intended for a 2-heat/1-cool heat pump system. The wiring should be pretty simple, as the terminal designations you listed are fairly standard. Be sure to follow up the wiring installation by checking the instructions for setup options.
