my understanding of the wiring diagram is the battery's you talk about
only run the thermostat memory. the house battery's run the the circuit. my diagram shows it is a 12v circuit, no transformer. you are right that a 12v thermostat should work . my last motorhome was a 110 transformer reduced to 12v circuit just like a house . that's why I always look twice at voltage ratting
