SUNIT DESCRIPTION AND OPERATION
The Watt Stopper’s WI-200 is a passive infrared wall switch that turns lighting
systems on and off based on occupancy and ambient light levels in the controlled
area. Pushing the AUTO/OFF button will turn the lights on. If no motion occurs
for a user-adjustable time delay of 15 seconds to 30 minutes, the lights will be
turned off.
Automatic On Mode
When the sensor is set to Automatic On mode, the WI-200 will turn the lights on
based on occupancy. It will hold the lights on until no motion is detected for a
user-definable time period of 15 seconds-30 minutes at which point it will turn
the lights off until motion is again detected. If the ambient light level is below the
light level setting when motion is detected, the sensor will turn the lights on
automatically. If the ambient light is higher than the user-defined light level, the
sensor will keep the lights off even if someone enters the controlled area. To
manually turn the lights on, cover the sensor’s lens. This keeps the ambient light
from reaching the sensor and the sensor will hold the lights on until it no longer
senses movement in the controlled area.
Manual On Mode
When the sensor is set to Manual On mode, the WI-200 will not turn the lights on
until the occupant pushes the AUTO/OFF switch. It will hold the lights on until
no motion is detected for a user-definable time period of 15 seconds-30 minutes
at which point it will turn the lights off. Once the lights have been turned-off,
the sensor has a 30 second reset delay during which it acts as if it were set to
Automatic On mode, and will turn the lights on if motion is detected without
having to press the AUTO/OFF switch. If no motion is detected during the 30
second reset delay, the AUTO/OFF switch will have to be pushed to turn the
lights on.
NOTE: In both Manual On and Automatic On mode, if the AUTO/OFF
switch is pressed while the lights are on, the lights will turn off and
not come back on until the AUTO/OFF switch is pressed again.
NOTE: When unit is set to Manual On mode, the light level should be
set to override. Otherwise, the lights will come on only when the
AUTO/OFF switch is pressed AND the ambient light is below the
configured level.
SCOVERAGE PATTERNS
The WI-200 will cover up to 1000 sq. ft. and over 40’ from the sensor. The Fresnel
lens in the sensor has multiple-cell viewing lenses in four tiers with a field of view
of 180°.

1. Make sure that the power has been turned off at the circuit breaker.
2. Connect leads to sensor with UL listed wire connectors (RED to load, BLACK
to the line, and GREEN for 120VAC or GREEN/YELLOW for 277VAC to the
ground). Cap the unused ground wire or unit could be damaged!
3. Attach the sensor to the wall by sliding the bottom screw through the keyhole
in the back of the unit and sliding the sensor down.
4. Insert the top screw into position and tighten.
5. Turn circuit breaker on. After 10-30 seconds, push the AUTO/OFF switch and
the lights will turn on. The delay is due to initial power-up of the sensor and
only occurs during installation.

SSENSOR ADJUSTMENT
See DIP SWITCH SETTINGS for DIP switch configurations.
1) Adjustments should be made after a
2 minute warm-up.
2) To test unit operation, press switch
to turn lights on. Set time delay to
minimum, leave the room and the
lights should go off after 15 seconds.
3) To test sensitivity (unit comes with
sensitivity set to high), make no
motion for 10 seconds. This 10 sec-
ond time period must be observed
in order for the LED to charge.
Move sideways in front of the sen-
sor at least 12" (LED will come on
when movement is detected). Typically, the sensitivity should be set at maximum.
4) The light level setting must be set when the lights would be off because of
sufficient ambient light.
5) Adjust the light level to minimum position and let the sensor time-out so lights
are off. Enter the space and lights should remain off. Adjust the light level until
the lights turn on. At this setting the lights will not turn on if light levels are
above the current level.
6) Re-adjust time delay to the desired setting. The time adjustment can be set
from 15 seconds to 30 minutes.
7) The unit comes with a tamper-proof plate which can be installed to prevent
the settings from being changed once they’ve been set..
PLEASE NOTE:
When the Manual On mode is being used, there is a 30 second reset delay after the
lights turn off. If motion is detected during the reset delay, the sensor acts as if it
were in Automatic On mode, and will turn the lights on when motion is detected
without having to push the AUTO/OFF switch. After the reset delay has elapsed
and no motion has been detected, the AUTO/OFF button must be pressed to
turn the lights on.
DIP Switch
Opaque adhesive tape is supplied
with the WI-200 so that sections of
the coverage area can be masked.
Since masking removes bands of
coverage, remember to take this
into account when troubleshooting
coverage.
±Warning±
The ground MUST be tightly
secured or the sensor will not work!
≠CAUTION≠
TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE
INSTALLING THE SENSOR.
