Installation Instructions

UNIT DESCRIPTION AND OPERATION

The WR-100 is a motion sensing wall switch that controls residential

lighting based on occupancy. The sensor uses passive infrared tech-

nology to sense human motion in a space. Passive infrared technology

relies on line-of-sight to maintain coverage and therefore the sensor

must have a clear view of activity in the space. Obstructions, such as

furniture blocking the sensor’s lens, may prevent occupancy detection.

Note: Windows, glass shower doors, etc. will obstruct the

WR sensor’s view and prevent detection.

Through the WR-100’s featured mode selection, a user can specify

“On” functions, light level, and time delay.

ON-Mode Functions (Automatic-ON & Manual-ON):

Automatic-ON

In the Automatic-ON mode, the WR-100 automatically turns lights on

when a designated space becomes occupied.

Manual-ON

When the WR-100 is set to Manual-ON, users must turn the lights on

by pushing the Auto-ON/OFF button. The lights will not turn on auto-

matically with occupancy in the Manual-ON mode.

Note: In both Manual-ON and Automatic-ON, the Auto-

ON/OFF button can be pressed to turn the lights off. The

switch must be pressed again to turn the lights back on.

Light level function:

The light level feature holds lights off when there is sufficient daylight

present. To override this feature and turn the lights on, press the Auto-

ON/OFF button.

Time Delay function:

The WR-100 automatically turns lights off after a

space becomes vacant and a pre-set time inter-

val, or time delay, elapses.

Coverage Patterns

The WR-100 has a coverage range of 180

degrees and a maximal coverage area of 300

sq. ft. To maintain its coverage capacity and

optimally detect motion, the WR-100 must have

a clear and unobstructed view.

INSTALLATION & WIRING

WARNING

Disconnect power to wall box by removing fuse or turning

circuit breaker OFF before

: installing the WR-100, replacing

lamps, or doing any electrical work

Remove existing wall plate and mounting screws. Pull switch

from wall.

Identify type of circuit.

Single Pole Circuit (See Fig. 1.1)

Two single wires connect to two screws. A

ground wire may also be present and con-

nected to a ground terminal on the switch.

Follow the directions for wiring a single pole

circuit. (See Step 4 and Figs. 2.2 & 2.3)

Three- Way Circuit (See Fig. 1.2)

Three single wires connect to three screws.

One screw is a different color or labeled

“common." Tag the wire connected to this

screw for identification. Depending on the

switch’s location, this wire is either hot or

load. A ground wire may also be present

and connected to a ground terminal on the

switch. Follow the directions for wiring a

three-way circuit. (See Step 4 and Figs. 2.4

& 2.5.)

Prepare Wires.

Strip the wires to the length (approximately 1/2 inch) indicated by the

“Strip Gage,” located on the back of the WR-100.

Single Pole Circuit (See Fig 2.2 & 2.3)

• Connect the green or non-insulated (copper) ground wire to the

green terminal of the WR-100.

• Connect a wire to the COMMON (or odd colored) terminal.

• Connect the remaining wire to the L1 terminal.

Note: The L2 terminal is not used in a single pole application.

Three-Way Circuit (See Fig 2.4 & 2.5 on the next page)

• Connect the green or non-insulated (copper) ground wire to

the green terminal of the WR-100.

• Connecting Wires (See Fig 2.1)

Use the following steps to connect wires.

• Loosen clamping screws. Insert stripped wire into back-wire hole.

Tighten clamping screw.

Call (800) 879-8585 For Technical Support

• Connect the tagged (common) wire to the COMMON (or odd col-

ored) terminal of the WR-100.

• Connect a single wire to L1 and L2 terminals respectively.

Notes about three way operation:

• If the switch backlight does not light after applying power, reverse

the placement of the L1 and L2 connected wires.

• Three way operation is only recommended for applications with

two WR-100s.

• When a WR-100 is used in a three-way application with another

WR-100, the duration of the time delay will be dependent upon the

last sensor triggered or the sensor with the longest time delay.

• If the WR-100 is used with a standard toggle switch, the toggle

switch must be turned on for the WR-100 to operate.

• If the WR-100 is not replacing another switch and is being newly

installed, the hot wire must be identified for connection to the com-

mon terminal.

Mounting and Alignment of WR-100

• Orient the WR-100 with its lens positioned above the Auto-ON/OFF

switch (lens up) and mount to wall box.

• Attach the wall plate.

Restore power.

Select the mode.

There are four selectable modes. Each mode determines the time

delay, On-mode, and light level settings. Chart 1 describes the

functionality of each mode.

To select a mode:

• Use the Auto ON/OFF button to first turn the lights on. Then press

and hold the Auto ON/OFF button until the lights turn off. If the

WR-100 is used in a three-way application, make certain the lights

are off by turning both WR-100s off and then select a mode for

each WR-100 indivdually.

• The red LED will blink to indicate the current operation mode. The

number of blinks corresponds to the mode number (i.e, three

blinks: mode three). Press the Auto-ON/OFF button to move

sequentially through the modes. The sequential series restarts at

mode one after advancing past mode four.

• Wait until the LED stops flashing (about 20 seconds). The lights will

turn on as an indication that the mode is set.

Note: Pressing the Auto-ON/OFF button before 20 seconds elapses

will change the mode.

Note: When the WR-100 is in the Auto-ON mode, press the

Auto-ON/OFF button to turn on the lights initially. After the time

delay elapses, the unit will function automatically. Anytime

power is lost to the sensor, this initialization procedure with the

Auto ON/OFF button must be repeated in order to turn on the

lights.

If you experience any difficulties, refer to the troubleshooting sec-

tion.

TROUBLESHOOTING

To test the sensor:

Set the sensor to mode four. Move within the coverage zone of the

sensor to trigger detection.The red LED should flash. Then move

out of the coverage zone. The lights should turn off within 15 sec-

onds. Repeat as necessary to ensure that the desired coverage

areas are within detection range.

Lights will not turn on (green back-light is visible):

• Press Auto-ON/OFF button. Lights should turn on. If not, check

sensor wire connections.

• Make sure the mode is set to an Auto-ON mode (modes one,

three, or four).

• See Step 4 on three-way installation for additional notes.

Lights will not turn on (back-light is NOT visible):

• Check sensor wire connections

• Make certain that the circuit breaker is on and functioning

• Check the light bulb

• Call 1-800-879-8585 for technical support

The WR-100 is ready for operation. The lights will now turn on

and off according to the mode set.

Putting a Stop to Energy Waste®

Lights will not turn off:

• Make sure no motion is occurring in the coverage area until the

time delay expires.

• Check the mode setting to verify selection of desired time delay.

Also, when mode two (Manual-ON) is being used, there is a 30

second reset delay after the lights turn off. If motion is detected

during this time, the sensor will turn the lights back on without

having to push the Auto-ON/OFF button.
