Wiring the C2N-RTHS

Description

The Crestron

C2N-RTHS is a wall-mounted temperature and relative humidity sensor that

communicates directly with any Crestron control system via the Cresnet

control network.

One-piece mounting makes the C2N-RTHS simple to install. The 1-1/2 in (38.1 mm)

diameter face protrudes just 1/8 in (3.2 mm) from the wall surface and is easily painted or

wallpapered to blend into the wall surface.

Installation

NOTES: Ensure the installation location is not close to a heat or humidity source and is

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. Sensors are suitable for mounting in dry or damp locations as

dened by the National Electrical Code.

• Install and use this product in accordance with appropriate electrical codes and

regulations.

• A licensed electrician should install this product.

• Mount sensors on a vibration-free surface.

NOTE: Before using the C2N-RTHS, ensure the device is using the latest rmware.

Check for the latest rmware for the C2N-RTHS at www.crestron.com/rmware. Load

the rmware onto the device using Crestron Toolbox™ software.

Complete the following procedure to install the C2N-RTHS:

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

2. Make a small hole near the center of the designated mounting site to verify that the

location is suitable.

3. Drill or cut a 1 in (26 mm) diameter circular hole in the wall at the desired position.

4. Route the Cresnet wires to the sensor. Use the four wire nuts included to connect

the wires (red to red, white to white, blue to blue, and black to black).
