Activation of Optional Sensors

UTY-CDPXZC Zone Controller Interface

Overview

The UTY-CDPXZC Zone Controller Interface supports optional temperature sensors for individual zone temperature monitoring and control.

Optional sensors are disabled by default and must be manually enabled through the AR-WDD1E wired wall controller.

Important: Confirm that all optional sensors are correctly installed and connected to the relevant zone module terminals before enabling the function through the controller.

1. Requirements

ComponentRequirement
Zone Controller InterfaceUTY-CDPXZC
Wired Wall ControllerAR-WDD1E
Optional Temperature SensorsInstalled and correctly connected to the applicable zone module terminals

2. Purpose

Enabling the optional sensors allows the system to:

  • Detect and use temperature inputs from sensors installed in individual zones.
  • Provide individual zone temperature feedback for improved comfort and control accuracy.
  • Control each configured zone using its local temperature reading.
  • Display zone sensor readings on the controller where supported by the system configuration.

3. Procedure

Complete the following steps using the AR-WDD1E wired wall controller.

1
Access the Menu

Press the Menu button twice.

2
Enter the Service Menu

Press and hold both top buttons simultaneously for approximately 5 seconds.

The Service (2/2) screen will appear.

3
Open Zone Settings

From the Service (2/2) screen, select Zone Initial Setting.

Press Enter to continue.

4
Enable the Optional Sensor

Scroll to Connection State of Op. Sensor.

Change the setting to Enable and confirm the selection.

5
Exit and Save

Press Back or Menu to return to the main operating screen.

The controller will automatically store the updated configuration.

Menu Path
Menu twice → Hold both top buttons for 5 seconds → Service (2/2) → Zone Initial Setting → Connection State of Op. Sensor → Enable

4. Confirming Sensor Operation

Once the optional sensor function has been enabled:

  • The zone controller will begin recognising temperature inputs from the connected sensors.
  • Each zone configured with an optional sensor can operate based on its individual temperature reading.
  • Zone temperatures may be displayed through the wall controller, depending on the system configuration.
If a sensor is not detected:
Check the sensor wiring, cable condition and terminal connections at the UTY-CDPXZC interface before changing any additional controller settings.

5. Troubleshooting

IssuePossible CauseRecommended Action
Optional sensor is not detectedSensor disconnected, wiring fault or poor terminal connectionInspect the sensor cable and confirm that each conductor is correctly seated in the zone module terminal.
Service Menu cannot be accessedThe button sequence was not completed correctlyPress Menu twice, then hold both top buttons simultaneously for the full 5 seconds.
Sensor is enabled but operation does not changeConfiguration has not been recognised or the sensor is not assigned correctlyConfirm the zone assignment and power-cycle the zone controller after completing the configuration.
Incorrect or unstable zone temperaturePoor sensor location, damaged cable or sensor faultCheck the sensor location, cable routing and sensor resistance in accordance with the applicable technical documentation.
