Remote Temperature/Humidity Sensors Crestron CHV-RTS/CHV-RTHS

Installation

1. Ensure that the location is not close to a heat or humidity source and

away from direct sunlight, skylights, and windows. When mounting

the sensor outdoors, do not place in direct sunlight, and do not place

where the sensor will be directly exposed to precipitation.

2. Locate an area on the wall that is free of miscellaneous wiring and

studs.

3. Make a small hole near the center of the designated mounting site to

verify that the location is suitable.

4. Drill or cut a 1 in (2.54 cm) diameter circular hole in the wall at the

desired position.

5. Route the wires from the thermostat to the sensor. For thermostat

connection details, refer to the latest version of Crestron CHV-TSTAT

& CHV-THSTAT Thermostats Operation and Installation Guide,

Doc. 8163.

NOTE: Maximum distance from sensor to thermostat is 500 feet

(152.4 m).

– Ordinary two-conductor thermostat wire (18 to 20 gauge) may be used

for runs up to 100 feet (30.48 meters).

– Longer runs should be low-capacitance twisted pair wire such as CAT3

(up to 250 ft, 76.2 m) or CAT5 (up to 500 ft, 152.4 m) network cable.

– Other cable types are satisfactory, provided the total capacitance is less

than 7000 pF.

6. Connect the wires from the thermostat to the 10 in (25.4 cm) sensor

pigtail (22 AWG x12" black/black twisted pair) using wire nuts. The

wires are non-polarized. (Refer to “Hardware Hookup” on page 5).

7. Press fit the sensor into the hole; the clips on either side of the sensor

hold it in place.
