NOTE: When the thermostat is in Unoccupied mode, the fan
will run only during heating or cooling operation, even if the

feature.
When the fan is not set to FAN ON (no icon displayed on ther-
mostat screen), the fan will run during heating and cooling
operation only.

will only enter Cooling mode (if the room temperature is above
the cooling set point). If AUTO is selected, the thermostat will
enter Heating or Cooling mode based on the room tempera-
ture and the heating and cooling set points. If PROGRAM

mostat will follow the Occupied and Unoccupied schedules
stored in its memory.
Auto-Changeover
When the thermostat mode is set to AUTO, the thermostat
will provide automatic changeover from Heating to Cool-
ing mode and Cooling to Heating mode when required. The
thermostat will automatically switch to maintain the desired
temperature setting. The thermostat does not need to be manu-
ally changed from heating to cooling or cooling to heating
operation.
