How To Use
Automatic Dust Sensing Mode
This feature monitors the air quality of the room to detect the
presence of particles, then adjusts the fan speed to improve
air quality to optimum conditions. Press the Automatic Dust
Sensing Mode Button to engage this feature. The screen will
display the animated Automatic Dust Sensing icon (shown
above), to indicate when this feature is active. The Dust Sen-
sor will continuously monitor the amount of airborne particles
in the environment and adjust the fan speed between Low,
Medium and High as needed to maintain optimum air quality.
The Quick Clean speed is not utilized when Automatic Dust
Sensing Mode is enabled. Please note that Automatic Dust
Sensing Mode is overridden when Sleep Mode is engaged to
ensure the unit is providing a consistent, low noise level during
nighttime sleep.
When To Use:
This feature allows the unit to reduce energy usage when
fewer airborne contaminants are present in the room. Because
active people and pets tend to stir up airborne particles, the
unit will tend to increase speed during peak periods of activity
in the room until lower readings are obtained. This feature is
ideal for rooms where activity fluctuates greatly based on the
time of day.
Note: The Dust Sensor will need to be cleaned periodically.
Please refer to CLEANING AND MAINTENANCE on page 17.
Sleep Mode Setting
This feature senses no light or low light conditions, and auto-
matically adjusts the unit to low speed. Press the Sleep Mode
button to engage this feature. The Sleep Mode icon (shown
above) will display. Ideal for use in bedrooms. Higher and more
powerful speeds may be used throughout the day with lower
speeds and minimal noise being preferable at night.
Note: When in low light or no light, with sleep mode selected,
the unit will only operate at low speed. This will override Auto-
matic Dust Sensing Mode and high-speed settings. In regular
light, the unit will operate at the previous setting.
