    Cool

    I replaced a 5Ton York Heat pump condensing unit with another brand. The control wiring for the York is diffrent from the norm. York has a 66 wire comming from the indoor unit. The wiring diagram is gone. Does anyone know of a site where i can find the York Heat pump diagrams ?

    Thanks
    Larry

    On York, if memory serves me, 60 is the first stage electric heat, and 66 is second stage electric heat. Most air handlers have only 1 stage, so connect 60 and leave 66 not connected.

    66 energizes the strip heater during defrost.

    How many times must one fix something before it is fixed?
