When PM2.5 readings return to healthy levels, set Lennox iComfort fan

Connect

Once you home's PM levels return to healthy levels, this sets your Lennox iComfort central air fan back to Auto.

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

This Action will set my thermostat's fan to AUTO indefinitely. Note: does not work when the thermostat is in Away mode.
