Humidity Sensor and Fan Control
The new Leviton Humidity Sensor and Fan Control
automatically detects excess humidity in a room
and activates the ventilation fan to lessen con-
densation which helps reduce mold and mildew.
The sensor uses a microprocessor combined with
state-of-the-art digital sensing technology to
continuously monitor and manage humidity levels
in areas of the home prone to condensation and
mildew. It features user-friendly controls to adjust
sensitivity, humidity level and time out settings.
The sensor can replace a single pole switch and
can be used with most bathroom or ventilation
fans or fan/light combinations. It is designed to fit
within a standard wallbox and requires a neutral
wire for operation.
Applications
Contemporary in design, the Humidity Sensor and
Fan Control is the ideal solution for controlling
ventilation in areas of high humidity, dampness or
rooms prone to condensation and mildew such as:
- Bathrooms
- Basements
- Laundry Rooms
- Home Spas
The sensor also helps reduce energy usage
by automatically operating the fan only when
needed to control excess humidity.
General Operation
Automatic Humidity Control Mode – The sensor will automatically turn the
fan ON upon detecting excess humidity. The sensor will continue to monitor
the ambient air and automatically turn the fan OFF when the humidity level
has dropped.
Manual Operation – For immediate ventilation needs, the user can manually
switch the fan ON or OFF by pressing the fan icon. The fan will run for 10
minutes and automatically turn OFF (time out period can be adjusted).
If humidity levels change, the sensor will shift into automatic mode and
time out accordingly.
Air Cycle Mode – The Air Cycle mode automatically turns ON a ventilation
fan for a set period of time and repeats the cycle hourly. (eg. 20 minutes
ON/40 minutes OFF each hour). This feature may be used in areas requiring
periodic ventilation on a continuous basis such as basements, spas or
public restrooms.
