Wireless LAN control for compatible air conditioners
Account setup, air conditioner registration, app operation, timers and troubleshooting
FGLair allows a compatible Fujitsu air conditioner fitted with a WLAN adapter to be operated and monitored from a smartphone or tablet through an internet connection. Available functions vary by air conditioner model.
Important: Remote operation may start or stop the air conditioner when it cannot be seen directly. Confirm the room is safe and advise anyone nearby before operating the system remotely.
1. Requirements
| Item | Requirement |
|---|---|
| Air conditioner | FGLair-compatible air conditioner with a built-in or optional WLAN adapter. |
| Wireless router | IEEE 802.11 b/g/n wireless LAN support. Refer to the WLAN setting manual for the connection method and router requirements. |
| Internet | An active and stable internet connection is required for setup, remote operation and monitoring. |
| Mobile device | The original manual lists Android 4.1 or later and iOS 8.0 or later. Current app availability and operating-system requirements may differ. |
| Documents | FGLair operating manual, WLAN setting manual and the operating manual for the air conditioner. |
2. Safety and wireless LAN precautions
- Regularly confirm that the air conditioner power supply is secure and that the unit is operating normally.
- Do not remotely operate the unit where infants, children, elderly people, sick people or anyone unable to regulate the temperature may be affected.
- Do not use the WLAN function in aircraft, hospitals, near medical equipment or near equipment using high-precision control or weak signals.
- The WLAN system uses the 2.4 GHz frequency band and may be affected by concrete, metal, microwave ovens, radio interference and distance from the router.
- Only connect the product to networks you are authorised to use.
- Unregister and initialise the WLAN adapter before disposal or transfer to another person.
3. Account and air conditioner setup
Create an account
| 1 | Install and open the FGLair mobile application. |
| 2 | Select Create Account. |
| 3 | Enter the requested user information, email address and password, then accept the terms and conditions. |
| 4 | Open the confirmation email and follow the link to complete account registration. |
Account limitation: The manual states that one email address and password can be registered per WLAN adapter. Additional users must use the same registered account credentials.
Register the air conditioner
- Sign in to FGLair.
- From the Directory or Account screen, select the Plus (+) button or Add a Device.
- Follow the WLAN setting manual for your adapter to connect the air conditioner to the wireless router.
- Confirm that the air conditioner appears in the Directory and shows its current operating status.
4. Operating the air conditioner
| Control | Operation |
|---|---|
| On / Off | Open the individual air conditioner screen and select the On/Off switch. |
| Operating mode | Select Auto, Cool, Heat, Dry or Fan. Only functions supported by the connected model will be shown. |
| Temperature | Use the up/down controls or trace the outer temperature ring. Auto, Cool and Dry: 18-30°C. Heat: 16-30°C. |
| Fan and airflow | Select fan speed and supported vertical or horizontal airflow settings. |
| Other functions | Depending on the model, Economy, Minimum Heat (10°C Heat), Powerful and Outdoor Unit Low Noise may be available. |
Control priority: If settings differ between the mobile app and a wired or wireless remote controller, the most recent operation takes priority. Timer settings created in the app and remote controller may both remain active.
5. Weekly timers
FGLair provides two weekly timer groups: Weekly Timer 1 and Weekly Timer 2.
- Open the side menu and select Timers.
- Select Timer 1 or Timer 2 and turn it on.
- Select Add Schedule.
- Set the power command, start time, operating mode, temperature and required days.
- Select Save.
The weekly timer operates using the clock in the smartphone or tablet. Allow for any device time difference. Unregistering the air conditioner deletes its weekly timer settings.
6. Status messages and notifications
The individual air conditioner screen may display icons for the following conditions. Icons only appear when supported by the connected model.
| Error message | Timer active | Prohibited operation |
| Defrost | Oil recovery | Pump down / startup / maintenance |
| Mode mismatch | Demand control | Filter sign |
Email notifications for errors can be enabled under Side Menu > App Settings. The app interface may also display other notification options depending on the application version and region.
7. WLAN adapter LED indicators
| Indicator state | Likely cause | Action |
|---|---|---|
| All LEDs off | No power, LEDs disabled in the app, or supported adapter is in Sleep mode. | Confirm air conditioner power. Press the WLAN Setting button to wake the adapter. Check the LED setting in the app. |
| LED 2 off or flashing rapidly | Router is off or the adapter is not connected correctly to the router. | Confirm router power and internet access, then repeat WLAN setup if required. |
| LED 1 flashing rapidly | The WLAN adapter cannot communicate with the air conditioner. | The air conditioner may have an error. Contact authorised service personnel. |
| Both LEDs flashing rapidly | WLAN adapter fault. | Isolate and restore power to the air conditioner, then repeat WLAN setup. |
8. Troubleshooting
| Issue | Checks and corrective action |
|---|---|
| Cannot operate from the app | Confirm power to the indoor unit and router, confirm the mobile device has internet access and is not in flight mode, and check that the WLAN adapter is not in Sleep mode. |
| Device is offline | Confirm the router has internet access and check the WLAN adapter LED indicators. |
| Cannot register the device | Enable Wi-Fi, connect the mobile device to the same network used for registration, confirm the router has internet access and verify the air conditioner is ready for registration. |
| Air conditioner already registered | Unregister it using the existing registered account. If the account is unavailable, contact the dealer or authorised service personnel and provide the MAC address shown on the WLAN label. |
| Weekly timer not operating | Turn the weekly timer off and on again. If the unit was unregistered, recreate the schedules after registration. |
| Airflow position differs from app | The position may have been changed by another app or remote controller. Set the airflow direction again. |
| Cannot sign in or reach service | Confirm the mobile device has internet access and retry. |
9. Important operating notes
- The app cannot operate or monitor the air conditioner when mains power is disconnected.
- The room temperature displayed in the app is approximate and should be used as a reference only.
- Remote app operation may not produce the normal indoor-unit reception beep.
- Available functions, screens and menu names may differ by air conditioner model and app version.
- If wireless reception is poor, move the router closer, adjust its position or use a suitable wireless LAN repeater.
Before transferring ownership: Unregister the device from the FGLair app, initialise the WLAN adapter using its setting manual and delete the app account when it is no longer required. Uninstalling the app alone does not delete account information from the service.
Reference: FGLair Wireless LAN Control Operating Manual, Part No. 9382385002. For WLAN connection procedures, always use the setting manual supplied for the specific adapter.
