    Ok, gave up last night. Plowing hot air, when on cool and nothing when on hot. Nothing works when I shut the breaker off on panel for the heater.

    What is crossed that I can change?

    Are you saying you are getting hot air when you turn the ac on? Did you set up the installer setup to energize the reversing valve in cooling or heat?

    Installer setup
    #170 needs to 7
    # 190 is the heatpump changeover. If it is a newer heatpump needs to be set at 0 if old needs set at 1
