Advantage Air Status Codes
Definitions and first-line troubleshooting for AA status codes
For Advantage Air wall-mounted touchscreens, mobile applications, sensors and control systems
Use this reference to identify the meaning of an Advantage Air status code and complete the recommended first-line checks before arranging service.
Important: If the displayed message begins with UNIT ERROR or uses a code that does not begin with AA, refer the issue to the original air-conditioning installer or service provider. The fault may relate to the air-conditioning equipment rather than the Advantage Air control system.
1. Complete a power reset first
Before investigating the displayed status code, complete the following reset procedure.
| 1 | Turn the air-conditioning system power OFF at the main switch or circuit breaker in the meter box. |
| 2 | Leave the power OFF for 15 minutes. |
| 3 | Restore power at the main switch or circuit breaker. |
| 4 | Wait a further 5 minutes after the touchscreen restarts, then test the system again. |
If the touchscreen does not restart: Contact the installer or support team and have the estimated installation date, builder or installer details, air-conditioner brand and control-system type available.
2. Communication and controller status codes
| Code | Meaning | Recommended action |
|---|---|---|
| AA1 | Communication error between Advantage Air components and the air-conditioning unit. | Complete the power reset. If the code remains, contact the air-conditioning installer and quote AA1. |
| AA2 | Multiple unit controllers detected. | Complete the power reset. If unresolved, contact the installer to inspect controller addressing and wiring. |
| AA3 | General communication error. | Complete the power reset. If the code remains, contact the installer and quote AA3. |
| AA44 | Communication error between the wall-mounted touchscreen and the control box. | Complete the power reset. If unresolved, the installer should check the touchscreen, USB connection, control-box power and communications. |
3. Internet, mobile application and remote-access codes
| Code | Meaning | Recommended action |
|---|---|---|
| AA22 | The wall-mounted touchscreen is not connected to the internet. | Open tablet settings, confirm Wi-Fi is ON and reconnect to the home network. Re-enter the password if required. If connected without internet, restart the router. Disable and re-enable remote access if the code remains. |
| AA26 | Remote access is working. | No fault is present and no action is required. |
| AA33 | Applications on the wall-mounted touchscreen are out of date. | Connect the touchscreen to the internet, open Google Play Store and update the applicable control app, AA Waca where used, and AA Service. Update existing apps only; do not install duplicate applications. Restart the touchscreen after updating. |
| AA42 | An Apple device cannot locate the Advantage Air touchscreen. | Update the touchscreen apps, confirm the touchscreen is connected to local Wi-Fi and connect the Apple device to the same Wi-Fi network before trying again. |
| AA43 | An Android device cannot locate the Advantage Air touchscreen. | Update the touchscreen apps, confirm the touchscreen is connected to local Wi-Fi and connect the Android device to the same Wi-Fi network before trying again. |
| AA45 / AA46 | Mobile or remote communication error. | Confirm mobile data permission is enabled for the Advantage Air app. Check the touchscreen Wi-Fi connection, then restart both the touchscreen and router before reconnecting. |
| AA48 / AA49 | The touchscreen has not been paired with the Apple or Android device. | Connect both devices to the same Wi-Fi network. Open the applicable control app and operate the system for at least 10 seconds. Disconnect the mobile device from Wi-Fi and test remote access. |
| AA50 | The Apple app has detected a new system. | For multiple systems, open iOS Settings, select the applicable MyAir app and change the setting from single-system to multiple-system operation. |
| AA71 / AA72 | The mobile device has no stored system and is not connected to Wi-Fi. | Reconnect the mobile device to the exact same Wi-Fi network as the touchscreen. Open the applicable app to pair with the system, then test remote access again. |
4. Temperature sensor status codes
| Code | Meaning | Checks |
|---|---|---|
| AA4 | No temperature sensors detected. | Confirm each sensor has the correct System ID in Setup > Advanced Info, only one zone DIP switch is assigned to each sensor and the battery connection is secure. |
| AA81 / AA82 / AA83 | A wall sensor is detected but has no zone allocated, or more than one zone is allocated. | Check System ID, confirm only one zone DIP switch is selected and inspect the sensor battery connection. |
| AA86 | Wireless wall sensor battery is low. | Replace or inspect the battery, then confirm System ID and zone DIP-switch allocation. |
| AA89 | Multiple sensors detected on the same zone. | Confirm each sensor has a unique and correct zone allocation. Check System ID, DIP switches and batteries. |
5. Commissioning and setup codes
| Code | Meaning | Action |
|---|---|---|
| AA10 / AA11 / AA60 / AA62–AA68 | Commissioning or setup error. | Contact the air-conditioning installer. These codes normally require configuration checks rather than user troubleshooting. |
| AA122T | RM2 DIP switches are set incorrectly. | Contact the air-conditioning installer to correct the RM2 DIP-switch configuration. |
6. Information to provide when requesting support
Provide the following details to reduce diagnosis time:
- The complete status code shown on the touchscreen or mobile app
- Estimated installation date
- Builder and installation-company details
- Air-conditioner brand and model where available
- Control system type, such as MyAir, e-zone or Zone10e
- Whether the 15-minute power reset changed the status
