ADJUSTING THE SEASONAL ALLERGY SETTING
The Halo is shipped from the factory with the Air Sensor set to Standard sensitivity. The
sensitivity is adjustable in order to accomodate sustained periods of worse-than-normal or
better-than-normal air quality. Adjust the Seasonal Allergy Setting by following the steps below.
1. Ensure that the Halo is powered on.
2. Press and hold the Mode Selector button for two seconds
to put the unit into Seasonal Allergy Adjustment Mode.
The Fan Speed Indicator will blink according to the current
Air Sensor Sensitivity (see diagram below).

and nothing will be reset.
