Sounds like your house batteries are dyeing. The thermostat needs 12 VDC control power to control the A/C. Is your converter working correctly? Is your fridge doing the same thing?

The furnace supplies power to the thermostat. The furnace switch must be on. The furnace gets its power from the HOUSE DC distribution buss in the HOUSE breaker panel/DC fuse panel not from anything up front in the chassis,
