    If you don't want to run the heat pump just switch the thermostat to emergency heat. It shuts off the heat pump and only runs the furnace.

    You can always switch it back as the ODA modulates up.

    Suggestion. Put in a Trane TUHM060. The furnace modulates to give you the heat you need when you need it. 60 may be slightly over but it will probably never run at max.
