DESCRIPTION AND OPERATION
RH-250 Multi-way Wall Switch Convertible Occupancy Sensors are designed to replace standard single pole and multi-way (3-way, 4-way)
switches. They are ideal for any room with multiple entries and any other indoor space where vacancy sensor-based controls with manual ON/
OFF capability are desirable.
Like standard switches, you can press the ON/OFF button to turn the light or fan (controlled load) ON and OFF. Unlike standard switches, the
RH-250 automatically turns OFF the controlled load after the coverage area has been vacant for a period of time (Time Delay). If motion is
detected within 30 seconds after it automatically turns OFF, the RH-250 automatically turns the load back ON.
While the sensor is factory preset as a Vacancy Sensor with manual ON operation, it can be adjusted to work as an occupancy sensor that turns
the controlled load ON automatically upon detection of occupancy in the area.
The RH-250 can be wired with up to three additional RH-250s for multi-way Manual/Auto–ON/OFF of one or several loads (up to one load
connected to each RH-250). It can also be wired to up to four RH-253 single pole momentary wall switches for multi-way Manual-ON/OFF
Automatic-OFF control of one load.
Lighted Switch
To help you locate the RH-250 in a dark room, the amber LED illuminates the ON/OFF button while the controlled load is OFF. When the
controlled load is ON, the LED is OFF.
Operating Modes
For multi-way operation of two or more RH-250s, we recommend that the Operating Mode be the same in all sensors related to the same load.
This makes it easier to understand the multi-way control operation as well as trouble shooting. There are two operating modes to select from:
MODE 1 Vacancy sensor (Manual-ON/OFF, Auto-OFF): The user must press the ON/OFF button to turn the load ON. The RH-250 keeps the
load ON until no motion is detected by any of the related RH-250s for the time delay period. There is also a 30 second reset delay after the
automatic shut-off. If motion is detected during this time, the sensor turns the load back ON automatically. After the 30 second reset delay has
elapsed, the ON/OFF button must be pressed to turn ON the load.
MODE 2 Occupancy sensor (Auto-ON/OFF with manual control and reset to auto after 5 minutes of vacancy): The load turns ON and OFF
automatically based on occupancy detection. Once turned ON the RH-250 keeps the load ON until no motion is detected by any of the related
RH-250s for the time delay period. If the load is turned OFF manually, automatic-ON is re-enabled when no motion is detected for 5 minutes.
This prevents the load from being turned ON after it was deliberately turned OFF.
Time Delay
The time delay can be selected by the user during set up. It can be adjusted to any of these fixed values:15 seconds/5 minutes/15 minutes/30
minutes. We recommend that the time delay be the same in all sensors related to the same load. This makes it easier to understand the multi-
way control operation as well as trouble shooting. For additional information on how to adjust it, please read the SENSOR ADJUSTMENT &
PROGRAMMING section of this installation manual.
Light Level
When the operating mode is set for occupancy sensor, Mode 2 (Auto-ON) this feature prevents the sensor from automatically turning the lights
ON if there is already enough light in the area.
In a multi-way application, each sensor monitors the light level at it’s location. If any sensor related to the load detects motion AND the measured
light level in that sensors area is lower than it’s Light Level setting, the load turns ON.
To adjust the light level, please read the SENSOR ADJUSTMENT & PROGRAMMING section of this installation manual.

Coverage Area
The RH-250 has a maximum coverage range of 180 degrees and a coverage area of 600 square feet (56
square 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.
NOTE: Windows, glass doors, and other transparent barriers will obstruct the sensor’s view and prevent
detection.
INSTALLATION & WIRING
These instructions describe only the 3-way circuit applications.
For information about other applications,
consult technical support.
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 RH-250 to a single pole or multi-way
circuit. If you are unable to clearly identify some or all of the
wires mentioned in this manual, you should consult with a
qualified electrician.
In a 3-way circuit (see Fig. 2), 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.
CAUTION
For your safety: Connecting a proper ground to the sensor provides protection against electrical shock in the event of certain
fault conditions. If a proper ground is not available, consult with a qualied electrician before continuing installation.
3. Prepare the Wires
Tag the wires currently connected to the existing switch so that they can be identified later. Disconnect the wires.
Make sure the insulation is stripped off of the wires to expose their copper cores to the length indicated by the
“Strip Gauge,” in Fig. 3. (approx. 1/2 inch).
4. Wire the sensor
Twist the existing wires together with the wire leads on the RH-250 sensor(s) as indicated in either step 4a or 4b. Cap wires securely using
wire nuts.
a. Wiring two RH-250s in a 3-way configuration
Connect the green or non-insulated (copper) GROUND
wire from the circuit to the green terminal on each RH-
250.
Connect the NEUTRAL wire from the circuit and from
the lamp (LOAD) to the white wire on the RH-master
250.
The term “master” designates the RH-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 RH-250.
Connect the power wire from the circuit box (HOT)
to the black wire on the auxiliary RH-250 and to the
TRAVELER 1 wire.
Connect the TRAVELER 1 wire from the black wire of the auxiliary RH-250 to the black wire of the master RH-250.
Connect the lamp power (LOAD) to the red wire on the master RH-250.
Cap the red wire on the auxiliary RH-250.
Connect the TRAVELER 2 wire coming from the yellow wire of another RH-250 to the yellow wire of the RH-250 that you are wiring.
