Frequently Asked Questions - CHV-RTS Crestron

How far can the CHV-RTS be mounted from the thermostat?

Using CAT5 cable, the sensor can be mounted up to 500 feet (152 meters) from the thermostat. For CAT3 cable, the maximum is 250 feet (76 meters).

Is the CHV-RTS wiring polarized?

No, the connection is non-polarized. You can connect the two wires from the sensor to the thermostat terminals in either orientation.

Can I paint the CHV-RTS sensor to match my wall?

Yes, the sensor's metal cap is primed and can be painted or wallpapered. Ensure the small gap around the outer edge remains unobstructed.

How many CHV-RTS sensors can I connect to one thermostat?

Up to four CHV-RTS sensors can be connected to a single compatible thermostat (depending on firmware version). For older firmware (1.xx), only two are supported.

What type of wire should I use for installation?

Crestron recommends low-capacitance twisted pair wire such as CAT3 or CAT5. Ordinary thermostat wire (18-20 gauge) can be used for runs up to 100 feet (30 meters).

What should I do if the thermostat is not receiving a signal from the sensor?

Check the wiring connection between the sensor and thermostat. Ensure there are no loose connections or open circuits. Refer to the Hardware Hookup section in the manual.

Can the CHV-RTS be used outdoors?

Yes, it is suitable for outdoor use in dry or damp locations, but avoid direct sunlight and exposure to precipitation. Ensure it is not placed where rain or snow can directly hit it.

What is the measurement accuracy of the CHV-RTS?

The temperature tolerance is ±1°F (±0.5°C) over the full range, and within ±1°F (typically +0.1°F/-0.4°F) at room temperature.

Does the CHV-RTS require its own power supply?

No, the sensor is powered by the thermostat through the connection wires. No external power supply is needed.

Can I connect both a CHV-RTS and a CHV-RTHS to the same thermostat?

Yes, but each channel supports up to two CHV-RTS sensors or one CHV-RTHS. You can mix them across different channels as long as the total number per thermostat does not exceed the maximum (typically 4).

Remote Temperature & Humidity Sensors: CHV-RTS & CHV-RTHS

Introduction

The CHV-RTS and CHV-RTHS are wall-mounted remote temperature and relative humidity sensors* designed for use with select Crestron® thermostats. Using CAT5 or similar low-capacitance wire, the remote sensor may be mounted up to 500 feet (152 meters) from the thermostat. One-piece mounting and a single non-polarized twisted-pair connection make the CHV-RTS and CHV-RTHS simple to install. The 1 1/2 inch (39 mm) diameter face of each protrudes just 1/8 inch (3 mm) from the wall surface and is easily painted or wallpapered to blend into the wall surface.

Up to four CHV-RTS sensors may be connected to a single CHV-THSTAT, CHV-TSTAT, CHV-TSTATEX, or CHV-TSTATEX-FCU thermostat (all sold separately). Up to two CHV-RTHS sensors may be connected to a single CHV-THSTAT or CHV-TSTAT thermostat (all sold separately).

NOTE: When connecting a CHV-RTS or CHV-RTHS sensor to a CHV-THSTAT or a CHV-TSTAT (models without infiNET EX ^® ), note that thermostat firmware version 1.xx supports two optional remote sensors, while thermostat firmware version 2.xx and later supports four optional remote sensor inputs, in any combination, for each thermostat.

NOTE: If the maximum number of sensors is exceeded, some of the sensors will be ignored by the system.

Setup

Installation

NOTE: 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 is directly exposed to precipitation. Sensors are suitable for mounting in dry or damp locations as defined by the National Electrical Code.

Complete the following procedure to install the CHV-RTS or CHV-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 desired area to verify the location is suitable.
3. Drill or cut a 1 inch (25 mm) diameter circular hole in the wall at the desired position.
4. Route the wires from the thermostat to the sensor. For thermostat connection details, refer to the Crestron CHV-TSTAT and CHV-THSTAT Thermostats Operations and Installation Guide (Doc. 8163), the CHV-TSTATEX Thermostat Operations and Installation Guide (Doc. 6989), or the CHV-TSTATEX-FCU Thermostat Operations and Installation Guide (Doc. 7206) at www.crestron.com/manuals.

NOTE: Crestron strongly recommends low-capacitance twisted pair wire such as CAT3 (up to 250 feet (76 meters)) or CAT5 (up to 500 feet (152 meters)) network cable when using remote sensors. Other cable types are satisfactory, provided the total capacitance is less than 7000 pF. Maximum distance from sensor to thermostat is 500 feet (152 meters).

NOTE: In situations where ordinary two-conductor thermostat wire (18 to 20 gauge) has been installed, it may be used for runs up to 100 feet (30 meters). This is not a preferred method of installation.

NOTE: If multi-conductor cables are used, the unused conductors must NOT be used for other purposes and must be left unconnected at both ends.

1. Connect the wires from the thermostat to the 10 inch (254 mm) sensor pigtail (22 AWG x 12" black/black twisted pair) using wire nuts. The wires are non-polarized. (Refer to "Hardware Hookup," below.)

Wiring the CHV-RTS and CHV-RTHS

1. Press fit the sensor into the hole; the clips on either side of the sensor hold it in place.

NOTE: The face of the sensor may be painted or wallpapered to match the wall. However, keep the small gap around the outer edge clear of any obstructions.

Hardware Hookup

CHV-RTS and CHV-RTHS sensors connect to the terminal blocks on the back plate of the CHV-TSTAT, CHV-THSTAT, CHV-TSTATEX, and CHV-TSTATEX-FCU thermostats (all sold separately).

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.

1. Separate the front plate from the back plate of the thermostat (it may be necessary to exert force when removing the faceplate).

Front Plate Removal

1. 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.

CHV-RTS (Single Channel) Hookup (Two Sensors Shown)

1. To connect sensors using two channels on the thermostat, wire up to two CHV-RTS sensors to the RS1 and RSR terminals and up to two additional CHV-RTS sensors (or one CHV-RTHS sensor) to the RS2 and RSR terminals as shown in the illustration on the following page.

Dual CHV-RTS and Single CHV-RTHS Hookup (Three Sensors Shown)

1. Note the orientation of the front plate connection pins and reattach the front plate (making sure the front plate snaps in place and no wires are pinched).

For additional information about the thermostat connections, refer to the CHV-TSTAT and CHV-THSTAT Thermostats Operations and Installation Guide (Doc. 8163), the CHV-TSTATEX Thermostat Operations and Installation Guide (Doc. 6989), or the CHV-TSTATEX-FCU Thermostat Operations and Installation Guide (Doc. 7206).
