Setting the Main Zone Sensor
anywAiR 1 ducted controller
Changing temperature control from the indoor-unit return-air sensor to a selected zone sensor
By default, the air conditioner regulates temperature using the return-air sensor in the indoor unit. Where zoning and compatible zone sensors are installed, a nominated main zone can instead become the temperature reference for heating and cooling demand.
Important: Isolate power before changing DIP-switch settings. Only approved anywAiR 1 hardware and compatible zone sensors should be used.
1. Prerequisites
| Check | Requirement |
|---|---|
| Controller communication | The anywAiR ducted controller must be installed and communicating correctly with the air conditioner. |
| Zone sensors | All required zone sensors must be paired, assigned and displaying valid temperatures. |
| Control box | Confirm the approved anywAiR 1 control box with the orange housing is fitted. |
| Firmware | Confirm the system firmware is current before changing the sensor configuration. |
2. Procedure - select a main zone sensor
| 1 | Isolate power. Turn off the air-conditioning system at the main isolator. |
| 2 | Locate the orange control box. Access the main anywAiR 1 controller and identify the bank of ten DIP switches. |
| 3 | Turn DIP switch No. 5 OFF. This disables return-air sensor control and enables selection of a zone sensor as the main temperature reference. |
| 4 | Restore power. Turn the air conditioner back on and allow approximately 2-3 minutes for the system to complete its start-up sequence. |
| 5 | Open the Zone screen. Navigate to the zone-control page on the anywAiR controller. |
| 6 | Select the main zone. Tap the grey thermometer icon beside the required zone name. The icon will darken to indicate that the zone sensor is now the active temperature reference. |
Control outcome: Once selected, the main zone sensor becomes the master temperature reference used to determine heating and cooling demand.
3. Verification
- Confirm that the selected zone's thermometer icon remains dark or highlighted.
- Confirm that the displayed control temperature reflects the selected zone sensor.
- Adjust the setpoint and verify that the system responds to the selected zone temperature.
- Check that no other zone is simultaneously shown as the main temperature reference.
4. Return to the default return-air sensor
| 1 | Isolate power at the main isolator. |
| 2 | Turn DIP switch No. 5 ON. |
| 3 | Restore power and allow the controller to restart. |
| 4 | Confirm temperature control has returned to the indoor-unit return-air sensor. |
5. Troubleshooting
| Issue | Checks |
|---|---|
| Thermometer icon will not select | Confirm DIP switch No. 5 is OFF, the controller has been restarted and the zone sensor is paired and online. |
| Temperature does not match the zone | Confirm the correct zone was selected and that the sensor is not affected by sunlight, drafts, heat sources or poor placement. |
| System still appears to use return air | Recheck DIP switch No. 5, fully power-cycle the system and confirm that the selected thermometer icon is highlighted. |
| FG81-FG83 sensor-related fault | Check sensor pairing, zone assignment, wiring and communication. Remove duplicate or invalid sensor assignments before restarting the system. |
Service note: Where the controller does not behave as described, confirm the exact control-box revision and firmware before replacing components. Hardware and menu behaviour may differ between anywAiR controller generations.
