condair CRC-NA 2-10V Wall Humidity Sensor

The CRC-NA 2-10V Wall Humidity Sensor is a device that measures the humidity of the environment it is installed in. It comes with a kit that includes the following components:

Product Installation Instructions

Before installing the CRC-NA 2-10V Wall Humidity Sensor, please refer to the installation overview in section 2 of the user manual.Follow the steps below for installation:

1. Open the screw of the housing and remove the mounting plate.
2. Fix the mounting plate (plastic screw facing downwards) with two screws at the location of installation.
3. Lead connecting label from the bottom into the housing and connect wires to the terminal according to the wiring diagram.
4. Snap housing onto the mounting plate and fix it with a screw (do not tighten screw too much).

Note: We recommend using 18-gauge wire, and a maximum 2 sec UI and its value is displayed.

Product Operation

The CRC-NA 2-10V Wall Humidity Sensor operates under the following conditions:

• Climatic Conditions: Temperature, Humidity

Mounting and Installation

Location:

Install the Condair CRC-NA in a protected and easy accessible place at least 1.5 m above the floor to the wall (mounting on flush-mounting or wall-mounting box). Observe the following placement notes:

• Do not place Condair CRC-NA in niches, behind, curtains, etc.
• Do not place the Condair CRC-NA near heat sources, within the area with direct air draft or direct sunlight.

Installation

Refer to installation overview in section 2.

1. Open the screw of the housing and remove the mounting plate.
2. At the place of location fix mounting plate (plastic screw facing downwards) with two screws.
3. Lead connecting label from the bottom into the housing and connect wires to the terminal according to the wiring diagram.
4. Snap housing onto the mounting plate and fix it with screw (do not tighten screw too much).

Note: We recommend using 18-gauge wire, and a maximum <100 ft distance from the unit.
