4b. 3-way wiring using two CD-250s:
Twist the existing wires together with the wire leads on the CD-250 sensors as
indicated below. Cap them securely using wire nuts provided. (See Fig. 4b)
• Connect the green or non-insulated (copper) GROUND wire from the circuit to
the green wire on the CD-250.
• Connect the NEUTRAL wire from the circuit and from the lamp (LOAD) to the
white wire on the master CD-250.
The term “master” designates the CD-250 that connects to the load.
• Connect the NEUTRAL wire from the circuit in the other wiring box to the white
wire on the auxiliary CD-250.
• Connect the power wire from the circuit box (HOT) to the black wire on the
auxiliary CD-250 and to the TRAVELER 1 wire.
• Connect the TRAVELER 1 wire from the black wire of the auxiliary CD-250 to
the black wire of the master CD-250.
• Connect the lamp power (LOAD) to the red wire on the master CD-250.
• Cap the red wire on the auxiliary CD-250.
• Connect the TRAVELER 2 wire coming from the yellow wire of another CD-250
to the yellow wire of the CD-250 that you are wiring.

4c. Multi-way wiring using one CD-250 and up to four RH-253s:
One CD-250 can be connected with up to 4 RH-253 single pole momentary wall
switches for multi-way Manual-ON/OFF control of one single load.
The CD-250
must be installed in the wiring wall box that connects to the load.
Connect the existing wires to the wire leads on the CD-250 sensor as indicated
below (See Fig. 4c). Cap them securely using wire nuts provided.
• Connect the green or non-insulated (copper) GROUND wire from the circuit to
the green wire on the CD-250.
• Connect the NEUTRAL wire from the circuit and from the lamp (LOAD) to the
white wire on the CD-250.
• Connect the power wire from the circuit box (HOT) to one terminal on each
RH-253 single pole momentary wall switch and to the TRAVELER 1 wire.
• Connect the TRAVELER 1 wire coming from each RH-253 wiring box to the
black wire of the CD-250.
• Connect the lamp power (LOAD) to the red wire on the CD-250.
• Connect the TRAVELER 2 wire to the other side of each RH-253 single pole
momentary wall switch and to the yellow wire of the CD-250.
