    Hunter Thermostat model 66440 Wiring
    I replaced a Honeywell T874R1475 Thermostat with a Hunter 44660 Thermostat. I have the labels from the Honeywell and need to know how it traslates to the Hunter thermostat.

    Honeywell
    o c/o valve heat
    x common
    g fan
    r power
    e them heat
    w2 aux
    y compressor


    Hunter labels
    rh 24 v power
    rc 24v cool
    y/o compressor
    w/b heating
    g fan
    y1 ss heat pump compressor


    Please help me figure out how the honeywell labels translate to the hunter labels.

    What is the part number for the subbase of the honeywell. That is the part that the thermostat fits on.

    Here is your old thermostat and subbase wiring. It is the first wiring diagram and figure number 7 on page number 5.

    You can transpose your wiring from the supplied above Honeywell diagram to your new hunter thermostat. I have no information on the hunter thermostat you bought.

    At this time I would like to mention that Hunter thermostats are junk in my opinion and in the opinion of many others. I would think twice before I would install it. You will be much better served by replacing the Hunter you bought with a new Honeywell. Just my opinion.
