The HVAC Fan will turn on once for the preset duration when the Haven Monitor detected PM Level to be higher than the preset unhealthy threshold.

This Trigger fires whenever the measured Particulate Matter of 2.5 microns in size (PM2.5) is above or below the threshold.

This action turns on the HVAC fan for one run cycle, with a configurable fan run duration.
