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 identifi ed in step 2 of
the instructions, you should consult with a qualifi ed electrician.
Steps 4a, 4b, and 4c describe each circuit application.
For information about other applications, consult technical support or the
WattStopper 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 CD-250 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.
Time Delay
The time delay can be selected by the user during set up. It can be adjusted to
any of these fi xed 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 section of this installation manual.
Coverage Area
The CD-250 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.

CAUTION — WARNING
To reduce the risk of overheating and possible damage
to other equipment, do not install to control a receptacle,
a motor-operated appliance, a fl uorescent lighting
fi xture, or a transformer-supplied appliance.
Disconnect power to the wall switch box by turning OFF
the circuit breaker or removing the fuse for the circuit before
installing the CD-250, replacing lamps, or doing any electrical work.
