Filtering
When the air cleaner is cleaning the air, either at your
command or when the heating and cooling system is operating,
bars on the display will sequence on and off to let you know
that it is working

Filter Life Indicator
This area of the display indicates filter usage. Bars will build
indicating usage increments of 20%, based on how the Air
Cleaner Control was set up. When all bars are filled and begin
to flash, it is time to change the filter. See the Maintenance
section on pages 2-3 for more details.

Active Cleaning
Four selections are available to choose the Air Cleaner Control
option that is best for you, beyond the cleaning that occurs
whenever your equipment is heating or cooling.

An Air Cleaner Control hard wired to the HVAC system power will result in the display backlight being lit 100% of the time. If the
Air Cleaner Control is powered by batteries, the backlight will come on for ten seconds when a button is pushed.
