    Thermosat Wiring
    I currently have a Honeywell manual thermosat controlling a oil burner and electric AC unit. I want to replace the thermosat with a digital Hunter thermosat, and want to make sure about how to properly wire it before I disconnect the old one.

    The Honeywell thermosat is wired as follows:

    There is a five wire bundle with red, white, yellow, blue and green wires. They are attached to the appropriate terminals, red - R, white- W, yellow - Y, blue - B, and green - G. In addition there is a separate yellow wire attached to the O terminal.

    The new Hunter thermosat has the five terminals: RC, RH, G, W, Y.

    Can someone instruct me on the proper way to wire the new thermosat based on what I have.
