We had our new Dutchman DENALI in Pennsylvania in late September on her maiden voyage. We ran into the double heater/AC operation. On the first evening, I resorted to going to the AC circuit breaker and shutting it off. We spent a nice warm evening. Next morning, I called the dealership and was informed about the "Auto" setting. Next night, we spent a warm night with only the heat running.
He had mentioned that the system was designed with the double operation when it was set to heat. He said it was to more quickly move the warm air throughout the unit when you first enter a cold unit. Something that was forgotten in the introduction.
So, if I understand you correctly, while the "double operation" can be used to move the heat quickly through a cold unit, If I select "auto", that shouldn't happen and only the heat part should operate?
