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.
