Off: The air cleaner will not call the fan for the purpose
of air cleaning . Note: If air cleaning is installed, air
cleaning will still occur during normal fan operation
during heating, cooling or other indoor air quality events .
Constant Clean: This option will provide the maximum
amount of air cleaning available . The air cleaner will be
active for 24 hours a day, seven days a week .
Automatic: The air cleaner will run a minimum of
30 minutes every hour . The air cleaner will monitor
the amount of time your heating and cooling system
runs; if 30 minutes is not reached the air cleaner will
automatically turn on . This will maximize the amount of
air cleaning while minimizing energy consumption .
Event Clean (3 hour cycle): When selected, the air
cleaner will run for 3 hours continuously and then return
to the most recent mode of Off, Automatic, or Constant

spike and outside air quality is at its worst, choose
this option . Your air cleaner will run continuously for
24 hours, then return to the most recent mode of Off,
Automatic, or Constant Clean .
Note: The thermostat will manage fan and air cleaning
selections when the selections overlap .
