AUTO MODE
MANUAL MODE
1. In Auto Mode, the Air Sensor evaluates the air quality in
the room and adjusts the fan speed accordingly. The word
“Auto” will be illuminated on the Control Panel.
The Air Quality Indicator will illuminate with a specific
color based on the air quality in the room:
• Blue = Excellent air quality = Low fan speed
• Purple = Moderate air quality = Medium fan speed
• Red = Poor air quality = High fan speed
1. In Manual Mode, the fan speed can be set to one of three
fan speeds (Low - Medium - High). At each level, an
increasing number of air wave icons will be illuminated:
• One air wave = Low fan speed
• Two air waves = Medium fan speed
• Three air waves = High fan speed
In this mode, the fan speed will not increase or decrease
depending on the quality of the air in the room.
The Air Quality Indicator will still change colors as the air
quality changes in Manual Mode.
2. The Air Sensor is set to “Standard” sensitivity at the
factory. This sensitivity can be changed to accommodate
periods of diering air quality.
Please see page 15 for more details on how to change the
Seasonal Allergy Setting.
NOTE: When the humidity level in the room is very high, it
is possible that condensation can develop on the
Air Sensor. This may cause the unit to believe the
air quality is poorer and cause the fan speed to
operate at a higher level. If the room has very high
humidity, it may be preferable to run the Halo in
Manual Mode rather than Auto Mode.
