INDOOR AIR QUALITY FUNCTIONS

EVENT-BASED™ AIR CLEANING (IF INSTALLED)

1. Select Air Cleaning from the Main Menu. Air Cleaning has two temporary events and three persistent modes that can be set. Air cleaning will activate the fan for the purpose of air cleaning.

2. Events (temporary) 3 Hrs: When selected, the air cleaner will run for 3 hours continuously and then return to the most recent mode of Auto, Continuous, or Off. This option only cleans the air when needed; an example would be after vacuuming. 24 Hrs: 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 Auto, Continuous, or Off.
   NOTE: The thermostat will manage fan and air cleaning selections when the selections overlap.

3. Modes (persistent)

   • Auto: 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.
   • Continuous: 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.
   • Off: The air cleaner will not run the fan for the sole 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.
