more info needed does it trip a circut breaker or just not operate when you shut down the 12v power if the later I would suspect 12v is necessary to run the unit ( why do You shut the 12v)

RJay is right, the thermostat runs on 12V.

If you shut off your 12V's you are also shutting off all control boards fridge, water heater, AC's and thermostat.
