Explanation of Filter Life LEDs (lights on the control panel)

Whenever the system is on, the color of the filter life LEDs (light emitting diodes) indicates the state of the individual filters in the system. The positions of the filter life LEDs on the control panel correspond to the actual positions of the filters within the system.

The filter life LEDs signal four possible stages in the life of the filter:

1. Green: The filter is still within 80% of its estimated life span.
2. Orange: The filter is approaching the last 20% of its estimated life span.
3. Red: The filter has reached the end of its estimated life span.
4. Red blinking: The filter has passed its estimated life span and should be replaced immediately.

   The IQAir system’s effectiveness is likely to have been reduced dramatically, either due to a reduction in airflow (particle filters are clogged) or a reduction in filter efficiency (gas phase filter is saturated).

The fan speed LEDs simulate the fan speed through the frequency of their rotation. The faster the rotation of the fan speed LEDs, the faster the actual fan speed of the system.
