DESCRIPTION AND OPERATION
CH-250 Multi-Way Wall Switch Vacancy 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
control 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 CH-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 CH-250 automatically turns the load back ON.
The CH-250 can be wired with up to three additional CH-250s for multi-way
Manual ON/OFF of one or several loads (up to one load connected to each
CH-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 CH-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.
Time Delay
The CH-250 keeps the load ON until no motion is detected by any of the related
CH-250s for the time delay period. 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 section of
this installation manual.
Coverage Area
The CH-250 has a maximum coverage range of 180 degrees and a coverage area

Pull the old switch out from the wall box. 2. Identify the type of circuit. You may connect the CH-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. - Page 3 “Strip Gage,” in Fig. 3. (approx. 1/2 inch). 4. Wire the sensor. Twist the existing wires together with the wire leads on the CH-250 sensor(s) as indicated in either step 4a or 4b. Cap wires securely using wire nuts.

4. Repeat as necessary to ensure that the desired coverage areas are within detection range. You can do this test for each CH-250 in your multi-way configuration. So that you can determine the actual coverage area for each multi-way switch individually, only the CH-250 that is in TEST mode will control the load. -
Page 6: Troubleshooting
Load will not turn OFF automatically: • Press ON/OFF button. If the controlled load turns OFF, go to next step. • The time delay can be set from 15 seconds to 30 minutes. Check the time delay setting for each CH-250 in your multi-way configuration. Ensure that all CH-250s have the same time delay setting. • Ensure that there is no movement within the coverage area for all the sensors related to the load for the set time delay. Hot air currents and heat radiant devices can cause false detection.
