Temperature & Humidity Sensors Crestron CHV-RTS & CHV-RTHS
6 • Temperature/Humidity Sensors: CHV-RTS/CHV-RTHS Installation Guide – DOC. 8189D
NOTE: Sensor wiring is non-polarized.
NOTE: Up to two CHV-RTS sensors or one CHV-RTHS sensor may be
connected to a single channel.
NOTE: Use a separate run of wire for each sensor.
NOTE: Sensor lines should not be run parallel to any other wiring. Lines
should cross other cables at right angles.
Complete the following procedure to connect the CHV-RTS or
CHV-RTHS to the system:
1. Turn off the circuit breaker.
CAUTION: Do not press on the LCD display of the thermostat
during this procedure, as this may cause the screen to crack.
2. Separate the front plate from the back plate of the thermostat (it
may be necessary to exert force when removing the faceplate).

3. To connect a sensor(s) to a single channel on the thermostat,
connect up to two CHV-RTS devices or one CHV-RTHS to the
RS1 and RSR terminals as shown in the following illustration.
