DESCRIPTION AND OPERATION
The RWDU500 Multi-way Dimming Wall Switch Vacancy Sensor is designed to
replace a standard single pole or multi-way (3-way, 4-way) switch or dimmer. It
is ideal for living and dining rooms, family rooms, bedrooms, bathrooms and any
other indoor area in a residential space where occupancy sensor-based manual
ON/OFF and Dimming control is desirable.
Like a standard switch, you press the ON/OFF/DIM button to turn the dimmable
lighting load ON and OFF. Unlike a standard switch, the RWDU500 automatically
turns OFF the controlled load after the coverage area has been vacant for a period
of time (Time Delay). If motion is detected within 30 seconds after it automatically
turns OFF, the RWDU500 automatically turns the load back ON. Like a standard
dimmer, once the lighting load is ON, you can dim it UP or DOWN by pushing and
holding the ON/OFF/DIM button. When you push the ON/OFF/DIM button to turn
the dimmable load ON, the RWDU500 recalls the last used dimming level.
While the sensor is factory preset as a Vacancy Sensor with manual ON operation,
it can be adjusted to work as an Occupancy Sensor that turns the controlled load
ON automatically upon detection of occupancy in the area.
The RWDU500 can be wired with up to 3 additional RWDU500s for multi-way
Manual/Auto –ON/OFF of one or several loads (up to one load connected to each
RWDU500). It can also be wired to up to 4 TM870STM single pole momentary wall
switches for multi-way Manual-ON/OFF Automatic-OFF control of one load.

Time Delay
The time delay can be selected by the user during set up. It can be adjusted to
any of these fixed values:15 seconds/5 minutes/15 minutes/30 minutes. It is
recommended to set all of the sensors related to the same load to the same time
delay to ease understanding of the multi-way control operation as well as trouble
shooting. For additional information on how to adjust it, please read the SENSOR
ADJUSTMENT & PROGRAMMING section of this installation manual.
Light Level
When the operating mode is set for occupancy sensor, Mode 2 (Auto-ON) this
feature prevents the sensor from automatically turning the lights ON if there is
already enough light in the area.
In a multi-way application with various RWDU500s, each sensor monitors the
light level at its location. If any sensor related to the load detects motion AND
the measured light level in that sensor’s area is lower than its Light Level
setting, the load turns ON. To adjust the light level, please read the SENSOR
ADJUSTMENT & PROGRAMMING section of this installation manual.
Coverage Area
The RWDU500 has a maximum range of 180 degrees
and a coverage area of 600 sq. feet (56 sq. meters).
The sensor must have a clear and unobstructed
view of the coverage area. Objects blocking the
sensor’s lens may prevent detection thereby
causing the light to turn OFF even though
someone is in the area.
Windows, glass doors, and other
transparent barriers will obstruct the
sensor’s view and prevent detection.
Lighted Switch
To help you locate the RWDU500 in a dark room, the green LED illuminates the
ON/OFF/DIM button while the controlled load is OFF. When the controlled load is
ON, the LED is OFF.
The lighted switch ON/OFF/DIM button can be used to manually turn ON and OFF
the lighting load and to dim it UP and DOWN.
To turn the load ON, tap firmly on the ON/OFF/DIM button once. The green LED
turns OFF and the load turns ON to the last used dimming level. The lighting load
may or may not appear to be ON depending on how low the lights were set the
last time they were dimmed.
Once the load has been turned ON, push and hold the ON/OFF/DIM button to dim
the lights UP or DOWN. To reverse the dimming direction momentarily release
the ON/OFF/DIM button, then push and hold it again. This feature will allow you to
reach the desired dimming level quicker.
OPERATINg MODES
For multi-way operation of two or more RWDU500s, it is recommended to set
the Operating Mode to be the same in all sensors related to the same load. This
recommendation will ease understanding of the multi-way control as well as
trouble shooting. There are two operating modes to select from:
MODE 1
Vacancy sensor (Manual-ON/OFF, Auto-OFF): The user must press
(tap) the ON/OFF/DIM button to turn the load ON. The RWDU500 keeps the load
ON until no motion is detected by any of the related RWDU500s for the time
delay period. There is also a 30 second reset delay after the automatic shut-
off. If motion is detected during this time, the sensor turns the load back on
automatically. After the 30 second reset delay has elapsed, the ON/OFF/DIM
button must be pressed to turn ON the load.
MODE 2
Occupancy sensor (Auto-ON/OFF with manual control and reset to auto
after 5 minutes of vacancy): The load turns ON and OFF automatically based on
occupancy detection. Once turned ON the RWDU500 keeps the load ON until no
motion is detected by any of the related RWDU500s for the time delay period. If
the load is turned OFF manually, automatic-ON is re-enabled when no motion is
detected for 5 minutes. This prevents the load from being turned on after it was
deliberately turned OFF.

INSTALLATION & WIRINg
These instructions describe single pole, 3-way and multi-way circuit applications.
If you are unable to clearly identify some or all of the wires identified in step 2 of
the instructions, you should consult with a qualified electrician.
Steps 4a, 4b, and 4c describe each circuit application.
For information about other applications, consult technical support or the
Pass & Seymour website.
1. Prepare the switch box.
After the power is turned OFF at the circuit
breaker box, remove the existing wall plate and
mounting screws. Pull the old switch out from
the wall box.
2. Identify the type of circuit.
You may connect the RWDU500 to a single pole
(see Fig. 2) or 3-way circuit (see Fig. 2a).
In a 3-way circuit, two traveler wires connect
to both switches. Another wire provides power
from the circuit box to one of the switches. A wire
connects from one switch to the load. A ground
wire may also be connected to a ground terminal
on the old switches. A neutral wire should also be
present in both wall boxes.
3. Prepare the Wires.
Tag the wires currently connected to the existing
switch so that they can be identified later.
Disconnect the wires. Make sure the insulation
is stripped off of the wires to expose their copper
cores to the length indicated by the “Strip Gage,”
in Fig. 3. (approx. 1/2 inch).
For your safety: Connecting a proper ground to the sensor
provides protection against electrical shock in the event of certain
fault conditions. If a proper ground is not available, consult with
a qualified electrician before continuing installation.

the green wire on the RWDU500.
• Connect the NEUTRAL wire from the circuit and from the lamp (LOAD) to the
white wire on the master RWDU500.
The term “master” designates the RWDU500 that connects to the load.
• Connect the NEUTRAL wire from the circuit in the other wiring box to the white
wire on the auxiliary RWDU500.
• Connect the power wire from the circuit box (HOT) to the black wire on the
auxiliary RWDU500 and to the TRAVELER 1 wire.
• Connect the TRAVELER 1 wire from the black wire of the auxiliary RWDU500 to
the black wire of the master RWDU500.
• Connect the lamp power (LOAD) to the red wire on the master RWDU500.
• Cap the red wire on the auxiliary RWDU500.
• Connect the TRAVELER 2 wire coming from the yellow wire of another
RWDU500 to the yellow wire of the RWDU500 that you are wiring.
