UNIT DESCRIPTION
The Watt Stopper
WN-100 is a motion sensing wall switch and nightlight that
controls lighting based on occupancy. The sensor uses passive infrared (PIR)
technology to sense human motion in a controlled space. It must have a clear
view of occupants in the space in order to detect occupancy. Obstructions such
as furniture blocking the sensor’s lens may prevent occupancy detection.
Note: Windows, glass shower doors, etc. will obstruct the WN-100’s view and
may prevent detection.
Through the WN-100’s mode selection, the user can specify ON functions and
time delay (see Sensor Adjustment & Programming section).
OPERATION
ON-Mode Functions (Manual-ON & Automatic-ON):
Manual-ON:
When the WN-100 is set to Manual-ON, users must turn lights on by pushing
the ON/OFF button. Lights will not turn on automatically with occupancy in
the Manual-ON mode. However, for a grace period of 30 seconds after
shut-off, the WN-100 will turn the load back on automatically when motion is
detected.
Automatic-ON:
In Automatic-ON mode, the WN-100 automatically turns lights on when a
designated space becomes occupied.
Note: In both Manual-ON and Automatic-ON, the ON/OFF button turns lights
off. The ON/OFF button must be pressed again to turn lights back on.
Time Delay:
The WN-100 automatically turns lights off after a space becomes vacant and
a preset time interval, or time delay, elapses. If lights are left on and no
motion is detected for the time delay selected (factory default = one hour), the
WN-100 automatically turns lights off.
Nightlight:
In the factory default mode, the nightlight remains on whenever the load is
off, regardless of occupancy.
The nightlight can be disabled from constant illumination (see “End User
Options” in the Sensor Adjustment & Programming section). However, when
motion is detected by the WN-100 while in Manual-ON mode, the nightlight
will automatically turn on and remain on until 90 seconds after the room
becomes vacant again. In this situation, nightlighting is provided only when
the room is in use.
If the nightlight remains disabled for 48 hours, it will automatically switch to
the default (enabled) mode.
