Im not quite sure where the beeping could be coming from on that 6535-3442 tstat. The diff means the tstat was set to high .
Low frequency beeping sound... Coleman Mach 6535-3442 Thermostat? Coleman Mach 6536A3351 True Air Digital 2-Stage Heat Pump/Gas Furnace RV Wall Thermostat - Black RV Air Conditioners
