Programming (continued)

Thermostat current setpoint does not match the display temperature.

•The thermostat may be in recovery from a Critical Event period. Depending upon thermal load of the system, it may take time for the temperature to reach the desired setpoint.

•Under excessive temperature loads (high/low outdoor temperature) the heating/cooling equipment may not be capable of maintaining the desired indoor temperature setpoint. The Heating/Cooling system may need servicing or upgrade. You may want to schedule a service call with a heating and cooling dealer for inspection of proper refrigerant levels, airflow, etc.

•In some cases, when the thermostat is located on or around the indoor air handler closet and the heater closet and the return air box is not sealed, the air handler will draw outdoor or colder air down the wall cavity or through the thermostat. The wall cavity, heater closet and return air box must be sealed.

•The heating or cooling may be in a temporary or permanent Hold. Press RUN to reset the hold and go back to the programmed setpoint.
