Installation Instructions

DESCRIPTION AND OPERATION

The RW3U600 Multi-way Wall Switch Occupancy Sensors are designed to replace
standard multi-way (3-way, 4-way) switches. They are ideal for any room with
multiple entries such as living and dining rooms, family rooms, bedrooms,
bathrooms, hallways, and any other indoor space where occupancy sensor-based
controls are desirable.

The RW3U600 has 2 modes of operation - vacancy or occupancy sensor. 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.

In vacancy sensor mode, you can press the ON/OFF button to turn the light or fan
(controlled load) ON and OFF like a standard switch. In occupancy sensor mode, the
lights will turn on automatically when the space becomes occupied. The RW3U600
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 RW3U600 automatically turns the load back ON.

Lighted Switch

To help you locate the RW3U600 in a dark room, the green LED illuminates the
ON/OFF button while the controlled load is OFF. When the controlled load is ON,
the LED is OFF.

Operating Modes

For multi-way operation, the Operating Mode must be the same in all sensors
related to the same load. There are two operating modes to select from:

MODE 1 Vacancy sensor (Manual-ON/OFF, Auto-OFF): The user must press the
ON/OFF button to turn the load ON. The RW3U600 keeps the load ON until no
motion is detected by any of the related RW3U600s 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 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 RW3U600 keeps the load ON until no
motion is detected by any of the related RW3U600s 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.

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. All of
the sensors related to the same load must be set for the same time delay. 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, each sensor monitors the light level at it’s location.
If any sensor related to the load detects motion AND the measured light level in
that sensor’s area is lower than it’s 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 RW3U600 has a maximum coverage
range of 180 degrees and a coverage area
of 600 square feet (56 square 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.

INSTALLATION & WIRING

WARNING

Disconnect power to the wall switch box by turning OFF

the circuit breaker or removing the fuse for the circuit before installing

the RW3U600, replacing lamps, or doing any electrical work.

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 RW3U600 to a single pole or multi-way circuit. These

instructions describe only the 3-way circuit application. For information about
other applications, consult technical support. If you are unable to clearly
identify some or all of the wires mentioned in this manual, you should consult
with a qualified electrician.

In a 3-way circuit (see Fig. 2), 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.
