4b.
Wiring one CH-250 and one RH-253 single pole momentary
switch for multi-way Manual-ON/OFF single load control.
IMPORTANT: The CH-250 must be installed in the
wiring wall box that connects to the load.
• Connect the green or non-insulated (copper) GROUND wire in each wiring box
to the green terminal on each CH-250 and RH-253.
• Connect the NEUTRAL wire from the circuit and from the lamp (LOAD) to the
white wire on the CH-250.
• Connect the power wire from the circuit box (HOT) to one terminal of the
RH-253 single pole momentary wall switch and to the TRAVELER 1 wire.
• Connect the TRAVELER 1 wire coming from the RH-253 wiring box to the black
wire of the CH-250.
• Connect the lamp power (LOAD) to the red wire on the CH-250.
• Connect the TRAVELER 2 wire to the other side of the RH-253 single pole
momentary wall switch and to the yellow wire of the CH-250.

5. Put all the new switches into their wall boxes.
Position the CH-250 switch(es) with the lens above the ON/OFF button (lens at
top, ON/OFF button at bottom). Use the captive screws on the mounting strap
to secure the switches to their wall boxes.
6. Restore power to the circuit.
Turn on the breaker or replace the fuse.
7. Make any necessary adjustments.
See the SENSOR ADJUSTMENT section for information.
8. Install cover plate.
Install industry standard decorator wall switch cover plate (not included).
