Connecting Optional LG Hydro Kit Accessories

Connecting the Remote Temperature Sensor
(LG Manufactured; Model No. ZRTBS01; Optional, Sold Separately)
The optional Remote Temperature Sensor is used in applications where it is desired to control the Hydro Kit
based on space temperature instead of leaving water temperature. It is a Type 3, NTC temperature sensor,
suspended in a round enclosure that measures less than an inch in diameter.
For placement considerations, see "Placing the Hydro Kit Controller" in the Installation Sec-
tion. Guidelines also apply to the Remote Temperature Sensor.
•
• Never operate Hydro Kit outside of the operational parameters as outlined in this manual and the product specifications. There is risk of
•
• Choose a location for the temperature sensor where an average temperature can be measured, where heating or cooling devices do not
inpact the sensor, or where the sensor is not impacted by a door opening.
• Do not install in direct sunlight.
• Use the LG-supplied 50 foot (15 m) communications cable with quick-connect plugs that is shipped with the Remote Temperature Sensor. A
communications error will occur if any other cables are used.
• After installation, the sensor is difficult to remove. Removing an installed sensor will damage the wall.
• Do not cover the sensor with wall paper. The sensor will not be able to detect temperature properly.
• If the communications cable between the sensor and the Hydro Kit is too long,
near the Hydro Kit.
• If the distance between the Remote Temperature Sensor and the Hydro Kit is more than 50 feet (15 m), use one or more 33 foot (10 m) LG
• Do not damage the quick connect plugs.
• Connect the male end of the communication cable at the Hydro Kit PCB terminal.
• Never operate Hydro Kit outside of the operational parameters as outlined in this manual and the product specifications. There is a risk
of malfunction.
• See the Pre-Commissioning section for function codes and instructions on accessing Installer mode that will be needed to set up Hydro Kit
accessories.
1. Ensure the wall interior is insulated behind the sensor. In-wall
drafts can affect the temperature reading.
Interior walls can contain high-voltage electrical wires. Ensure there are
no electrical wires in the wall at the selected drilling location. Drilling into
electrical wires can result in severe injury or death.
Interior walls can contain water pipes, metal structural elements and
other obstacles. Ensure there are no water pipes or other obstacles in
the wall at the selected drilling location. Drilling into water pipes or other
obstacles can result in wall damage.
