Why does the display temperature begin to climb when the cooling system is running?
If the displayed temperature climbs when the cooling system is running and it is clear that the house is becoming cooler, this may be the result of high current, causing the inside of the thermostat to heat up. Have your system checked by a local contractor. • Why does my thermostat beep? This thermostat does not have the capability of making an audible noise such as a beeping. The noise you are hearing is likely from another electronic device which is near the thermostat. Check for a smoke detector or security system.
