Quick Guide

This document provides installation and operation instructions for the Condair DCC-NA 0-10V Digital Duct Humidistat Package. Key information includes:

Passwords: User/display parameters (0009), Control parameters (00241).
Wiring: Use 18-gauge wire, maximum distance
Mounting: Duct sensor requires uniform airflow; wall unit must be at least 1.5m above the floor.
Configuration: Parameters are accessed via the keypad using the specified passwords.

Mounting and Installation

Duct Sensor (1509857):

Install in an area with well-mixed, uniform airflow.
If used as a supply air sensor, mount downstream of steam distribution at 1.5 times the absorption distance (typically 10-12 ft / 3-3.7m).
If used as a return air sensor, mount close to the air inlet but downstream from any return fan.
Drill a 16 mm (5/8") hole and 4 holes for self-tapping screws.
Insert probe, fix housing with screws, and ensure the gasket is applied centrally.

Wall Humidistat (2520261):

Install in a protected, accessible location at least 1.5m above the floor.
Mount on a flush-mounting or surface-mounting box.
Remove the mounting plate, connect wires, fix the plate to the box, and snap the housing onto the plate.

Wiring

Refer to the wiring diagrams in the manual for specific connections based on your system configuration (e.g., RS, EL, GS, US, SE, DL, ME). Ensure the factory jumper is correctly positioned. The unit operates on 24V AC/DC.

Operation and Configuration

The LCD display shows actual humidity and setpoint. Use the keypad to adjust settings:

Switching On/Off: Long press the power button.
Adjusting Setpoint: Briefly press the up/down arrows.
Parameter Access: Press the up and down buttons simultaneously for 3 seconds. Enter the code (0009 for user, 00241 for control) using the up/down buttons and confirm.

Sensor Calibration

If calibration is required:

Press the % button for > 2 seconds until the UI value is displayed.
Press the % button to see the calibration value.
Use UP/DOWN buttons to calibrate.
Press the % button to save.

Practical help

Common problems

AL5 or AL7 error code

The external sensor value is below 5% RH. Check the cabling of the DCC and CDC units. Once fixed, acknowledge the alarm by pressing the button.

Err2, Err3, or Err4 error code

Indicates a hardware or memory problem. The device must be replaced.

Sensor reading inaccurate

Check if the sensor is installed in an area with uniform airflow. If necessary, perform sensor calibration via the keypad.

Before use

Verify that the power supply is 24V AC/DC.
Ensure 18-gauge wire is used for connections.
Confirm the wall unit is mounted at least 1.5m above the floor.
Check that the duct sensor is placed in an area with uniform airflow.
Ensure the factory jumper is correctly installed for your specific configuration.

Specs in practice

Operating Voltage: 24V AC/DC ± 10% is required for operation.
Max Cable Distance: Wiring distance should not exceed 100 ft (approx. 30m) from the unit.
Output Signal: DC 0-10V output for control systems.

Images and diagrams

The manual includes specific wiring diagrams for different system types (RS, EL, GS, US, SE, DL, ME).
Dimensional drawings are provided for both the duct sensor and the wall humidistat to assist with mounting.
