Passive Infrared Wall Switch
Occupancy Sensor

UNIT DESCRIPTION AND OPERATION
The PW Passive Infrared Wall Switch sensors use advanced passive infrared
(PIR) technology.
The PW sensor can turn a load on, and hold it on as long as the sensor
detects occupancy. After no movement is detected for the selected time delay,
the lights switch off. A “walk-through” mode can turn lights off after only 3
minutes, if no activity is detected after 30 seconds following an occupancy
detection.
The PW-100 has one relay and one ON/OFF button. The PW-200 contains
two relays and two ON/OFF buttons to allow control of one or two loads
independently. Pressing a button toggles the state of the corresponding relay.
PW sensors contain a light level sensor. If adequate daylight is present, the
sensor holds the load OFF until light levels drop, even if the area is occupied. In
the PW-200, light level only affects the load on Relay 2. Users can overrule the
hold OFF function by pressing the ON/OFF button. See Light Level Adjustment.
Turning Load(s) ON (ON Mode)
The relays are programmed independently for either Auto ON or Manual ON. In
either mode, the load can be turned ON or OFF using the ON/OFF button.
Manual ON
DIP 8 ON
for Relay 1
DIP 9** ON
for Relay 2
With an ON Mode DIP switch in the ON position, the occupant
must press the ON/OFF button to turn ON the load. The sensor
keeps the load ON until no motion is detected for the selected
time delay. There is a 30 second re-retrigger delay. If occupancy
is detected during the delay, the sensor turns the load back ON.
After the re-trigger delay elapses the ON/OFF button must be
pressed to turn ON the load.
** PW-100: Switch 9 is not used. PW-200: Switch 9 default is ON to comply
with CA Energy Commission Title 24 bi-level switching requirements.
Auto ON
DIP 8 OFF for
Relay 1
DIP 9** OFF
for Relay 2
With an ON Mode DIP switch in the OFF position, the load turns
ON and OFF automatically based on occupancy. If the load is
turned OFF manually, Presentation Mode operation applies. This
prevents the load from turning ON automatically after it was
deliberately turned OFF. Pressing the button to turn lights ON
returns the sensor to Auto ON mode.
Shading indicates default operation and switch setting.

PW-100 1 Manual ON 8 ON
PW-100-347 1 Manual ON 8 ON
PW-200 1 Auto ON 8 OFF
2 Manual ON 9 ON
PW-200-347 1 Auto ON 8 OFF
2 Manual ON 9 ON

Test/20 min
(DIP 1, 2, 3, OFF)
Presentation Mode is a feature of the Auto ON mode.When both relays are
manually turned OFF the PW holds the lights OFF until no motion has been
detected for the duration of the Time Delay. With subsequent occupancy, the PW
turns the load ON. If both relays are ON and one relay is manually turned OFF
this relay remains OFF until both the Time Delay and retrigger delay expires for
the relay that is ON, after that time the ON Mode control settings again apply.
Time Delays
The PW sensor holds the load ON until no motion is detected for the selected
time delay. Select the time delay using DIP switch settings. In the PW-200, both
relays use the same delay.
A Test Mode with a short time delay of 5 seconds is
set when DIP switches 1, 2, & 3 are OFF. It cancels
automatically after ten minutes, or when you set a
fixed time delay. When the Test Mode times out, the
sensor assumes a 20 minute time delay. To restart
Test Mode, change the time delay setting to any fixed
amount and then return it to the Test setting.
Walk-Through
Mode
(DIP #4 ON)
The PW sensor turns the load OFF three minutes after
the area is initially occupied, if no motion is detected
after the first 30 seconds. If motion continues beyond
the first 30 seconds, the set time delay applies.
High (DIP #5 OFF)Default setting. Suitable for most applications.
PIR Sensitivity Adjustment
The PW sensor constantly monitors the controlled environment and
automatically adjusts the PIR to avoid common ambient conditions that can
cause false detections, while providing maximum coverage.
Fixed Time Delay
(DIP 1 ON, 2 & 3 OFF)
Time delays are 5, 10, 15, 20 (default), 25, or 30
minutes.
Reduces sensitivity by approximately 50%. Useful in
cases where the PIR is detecting movement outside of
the desired area (also consider masking the lens) and
where heat sources cause unnecessary activation.
Low, 50%
(DIP #5 ON)
Visit our website for FAQs: www.wattstopper.com
Walk-Through
The Walk-Through mode shortens the time delay to reduce the amount of time
the load is ON after a brief moment of occupancy, such as returning to an office
to pick up a forgotten item then immediately exiting.
No Walk-Through
(DIP #4 OFF)
Walk-Through mode disabled.

COVERAGE PATTERNS
Coverage testing has been
performed according to the
NEMA WD 7 guideline. For best
performance, use in spaces not
larger than 15’ x 12’.
PIR Sensor
The sensor has a two-tiered,
multi-cell viewing Fresnel lens with
180 degree field of view. The red
LED on the sensor flashes when the
PIR detects motion.
Masking the lens
Opaque adhesive tape is supplied
so that sections of the PIR sensor’s
view can be masked. This allows
you to eliminate coverage in
unwanted areas. Since masking
removes bands of coverage,
remember to take this into
account when troubleshooting
coverage problems.

Alerts
The PW can provide audible and/or visible alerts as a warning before the load
turns OFF.
Unit will beep at one minute*, at 30 seconds and at 10
seconds before turning OFF load. When Walk-Through
is active, the unit beeps three times at 10 seconds
before the load goes OFF.
*If Visible Alert is also ON, the one-minute time-out
warning beep is replaced by the visible alert.
Audible Alerts
(DIP #7 ON)
No audible warnings provided.
When only one minute is left in the time delay, the
load connected to the relay turns OFF for one second.
This provides a one minute warning before the load(s)
are turned OFF by the sensor.

1. Make sure that the power has been turned OFF at the circuit breaker.
2. Connect wires to the PW flying leads as shown in the
wiring diagram that is appropriate to the PW model and
electrical supply. The 2 ground wires (green and green/
yellow) must be fastened to ground for the sensor to
work properly.
3. Attach the sensor to the wall box by inserting screws into
the two wide holes on the top and bottom of the attached
metal bracket. Match them up with the
holes in the wall box and tighten.
4. Turn the circuit breaker ON. Wait one
minute, then push the Auto ON/OFF switch
for each load and the lights will turn ON.
There is a delay due to initial power-up
of the sensor that only occurs during
installation.
5. Test and adjust the sensor if necessary.
6. Install industry standard decorator wall
switch cover plate (not included).

TROUBLESHOOTING
Lights do not turn ON with motion (LED does flash)
1. Press and release each button to make sure that the correct lights come
ON for each relay. If the lights do NOT turn ON, check wire connections,
especially the Load connection. If the lights turn ON, verify that the
correct On Mode is selected in DIP switches 8 and 9.
2. Check to see if light level control is enabled: cover the sensor lens with
your hand. If the lights come ON, adjust the light level setting.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
Lights do not turn ON with motion (LED does not flash)
1. Press and release each button to make sure that the correct lights come
ON for each relay. If the lights turn ON, verify that Sensitivity is on High.
2. Check the wire connections, in particular, the Line connection. Verify that
connections are tightly secured.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
ADJUSTMENTS
Sensor Adjustment
Remove the wall plate. Remove the button cap by firmly squeezing together the
top sides of the button assembly. Gently pull it away from the unit.
When the adjustments are completed, replace the button cap by inserting its
hinges into the tabs on the main unit and then squeeze the top of the button while
pressing it into the unit. Reinstall the cover plate.
Light Level Adjustment
The light level can be set with loads ON or OFF. To enable light level control and
set the threshold: 1) Make sure the room is lit appropriately. 2) Put the sensor
into TEST mode (see Time Delay switches). You have 5 minutes to complete the
procedure. 3) Press and hold the ON/OFF button (Relay 1button on the PW-200)
for 3 seconds, until you hear a beep. 4) Step away from the sensor. After 25
seconds a beep sounds, indicating that the threshold level is set. This threshold
is retained, even if power is lost, until it is re-set or disabled. In the PW-200, light
level control only affects Relay 2.
To disable light level control, press and hold the Relay 1button for 7 seconds,
until a double beep tone sounds.
Reset to Default
Use the DIP Switch Settings tables on the previous page to return features
to factory settings. To reset the PW press and hold the Relay 1button for 10
seconds, until a triple beep sounds. This resets the sensor and disables light
level control (the brightest ambient light will not hold the light OFF).

detected. To verify proper operation, set DIP switch 1 to ON, then reset
switches 1, 2, and 3 to OFF to start Test Mode. Move out of view of the
sensor. The lights should turn OFF in approximately 5 seconds.
2. Verify that the sensor is mounted at least six feet (2 meters) away from
any heating/ventilating/air conditioning device that may cause false
detection. Verify that there is no significant heat source (e.g., high
wattage light bulb) mounted near the sensor.
3. If the lights still do not turn OFF, call 800.879.8585 for technical support.
Sensing motion outside desired areas
1. Select PIR Sensitivity – Low (DIP switch 5 = ON) if necessary.
2. Mask the PIR sensor’s lens to eliminate unwanted coverage area.
Red LED is lit all the time and the sensor features don’t work.
1. Check DIP switches 1,2,3. If they are all ON the unit is in Service Mode.
Set the DIP switches to a valid Time Delay setting.
2. If re-setting the Time Delay switches does not clear the LED call
technical support.
