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.

The CH-250 has a maximum coverage range of 180 degrees and a coverage area
