Connect the existing wires to the wire leads on the RD‑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 RD‑250.
• Connect the NEUTRAL wire from the circuit and from the lamp (LOAD) to the
white wire on the RD‑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 RD‑250.
• Connect the lamp power (LOAD) to the red wire on the RD‑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 RD‑250.

5. Put the RD‑250s (and RH‑253s if applicable) into their respective wall boxes.
Position them with the lens positioned above the ON/OFF/DIM button (lens at
top, ON/OFF/DIM button at bottom). Secure to the wall box with the screws
provided.
6. Make any necessary adjustments.
See the SENSOR ADJUSTMENT &PROGRAMMING section for information.
7. Install cover plate.
Install industry standard decorator wall switch cover plate (not included).
8. Restore power to the circuit.
Turn on the breaker or replace the fuse.
INITIAL POWER-UP DELAY & CALIBRATION
There is an initial warm‑up and calibration period the first time power is applied
to the unit, after a power failure lasting more than 5 minutes and after the
dimming load is replaced. If the sensor is in Mode 2, (automatic‑ON) it may take
up to 1 minute before the lights turn ON. However, the lights can be turned ON/
OFF and dimmed manually by pressing the ON/OFF/DIM button at any time when
power is supplied to the unit.
Load Calibration: The RD‑250 calibrates its dimming range to the load’s wattage
rating by briefly dimming the load up and down from its minimum output (approx.
10%) to its maximum.
SENSOR ADJUSTMENT & PROGRAMMING
To adjust the RD‑250, you use controls located under the ON/OFF/DIM button.
The wall switch cover plate must be removed to gain access to the mode button
and adjustment dials under the ON/OFF/DIM button.
