Smart Fan Operation

This feature allows the fan to run continuously during Occupied 1, 2
or 3 and automatically de-energize during Unoccupied, except when
necessary to heat or cool. To use this feature, place the thermostat in
the Program On mode. Next, press the FAN button to display the
FanOn icon (see below).
Fan On indicates constant fan operation.
If Fan On is selected the fan will run
continuously at all times, except in Off,
and will only run if there is a heating or
cooling demand in Unoccupied periods.
Pressing the FAN button toggles this
feature on or off.
