    Thermostat wiring on RTH6350D Honeywell?
    Hello I like to install a thermostat to a natural gas furnace.
    Old Thermostat wiring:
    Honey Well;
    g-green
    c-blue
    r-red
    w-white
    y-yellow

    New Thermostat RTH6350D Honey Well;

    Take another look normally the instructions are right,, I hope you killed the power to furnace before starting project as its very easy to fry the transformer while changing tstats.
