INDOOR AIR QUAlITy FUNCTIONS

Press [AIR ClEANING]

 on the Home screen to enter 

the Air Cleaning screen .

If installed, air cleaning can operate in five different 
modes . Air cleaning will activate the fan for the purpose 
of air cleaning .

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 
Clean . This option only cleans the air when needed; an 
example would be after vacuuming.

Allergies (24 hour cycle):

 When seasonal allergies 

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,
