Coleman Mach 6536A3351 Digital 2-Stage Heat Pump/Gas Furnace RV Wall Thermostat - White
My current thermostat defaults to 72 degrees several times while using the furnace. Do you know if this has been fixed. I have seen several others with the same problem.

The thermostat uses 72 as a reset set point when the thermostat drops voltage, most likely due to a weak ground.
