Overview
The UTY-FGAN1 Wi-Fi module connects Fujitsu air conditioning systems to the IntesisHome or AnywAIR mobile app.
During setup, the LED indicator provides clear visual feedback for each connection stage. Understanding these signals helps diagnose connection issues quickly.
1. LED Status Codes – Setup Sequence
| LED Colour / Pattern | Status Meaning | Description / Action |
|---|---|---|

| Green – Blinking | Checking | Module verifying internal configuration parameters. |
| Yellow – Blinking | Configuring | Device is writing configuration settings (can take up to 2 minutes). |
| Red – Blinking | Connecting | Attempting to connect to access point and server. Wait up to 2 minutes. |
| Off | Connected & Working | Wi-Fi configuration successful, system online. |
2. Extended LED Colours – IntesisHome-Specific
| LED Colour | Blinking Behaviour | Status / Description |
|---|---|---|
| Blue (Blinking) | Performing WPS connection (up to 2 minutes). | |
| Magenta (Blinking) | WPS connection error — incorrect or failed pairing attempt. | |
| White (Blinking) | Device identification in progress. | |

3. Alternate Blink Error Codes
| LED Combination | Pattern | Meaning / Corrective Action |

4. Key Notes for Technicians
During setup, ensure router signal strength > -70 dBm for stable connection.
The LED will turn off only when configuration is complete and communication is established.
If the LED remains red or magenta, reset the device (hold reset for 10 seconds) and reattempt setup.
Use the IntesisHome app or Fujitsu AnywAIR app to complete registration.
Avoid connecting to 5 GHz Wi-Fi networks — 2.4 GHz only is supported.
