Unless someone modified the system, there is NO hidden switch or any other switch that is stopping the roof AC's from operating. There MUST be 120 power to the Roof AC's. Are you positive there is 120 power thru out the RV on APU? The wall tstat is 12 volt controlled and will function without 120 power. It TAKES 120 power to run the Fan and Compressor. Doug
