My Hunter thermostat (Model 44110 ) sometimes does not lower the temperature reading when the actual ambient temperature is already lowered by the AC it controls. I put a Radio Shack digital thermometer above the Hunter thermostat. For instance, the thermometer already shows 82 F but the Hunter thermostat still shows 84, so the AC keeps running. What's strange is that if I set desired temperature to higher than the display temperature, to 85 for instance, the AC stops, and surprisingly, the Hunter thermostat starts to drop its reading, eventually to 82 (if the outside heat doesn't heat the house up that quickly). Why does the thermostat stop lowering its reading unless the AC is turned off (or the desired temperature is set higher)? It happens quite often. The battery is not low. Thanks for help.
