The Fujitsu General Wireless LAN Adapter (models UTY-TFSXZ1, UTY-TFSXZ2, UTY-TFSXZ4) is an optional accessory designed to enable remote control of air conditioning units via a smart device. This adapter facilitates communication between an indoor air conditioning unit and a wireless router, allowing users to manage their air conditioner settings through the FGLair mobile application.
Function Description:
The primary function of the Wireless LAN adapter is to provide wireless connectivity for Fujitsu General air conditioning units. By installing the FGLair mobile application on a smartphone or tablet, users can control various functions of their air conditioner from outside their home or within their local network. The adapter acts as a bridge, translating commands from the mobile app into signals the air conditioner can understand and vice versa.
Key control functions available through the FGLair app include:
- Operation on/off: Powering the air conditioner on or off.
- Operation mode setting: Selecting different operating modes (e.g., cooling, heating, fan, dry).
- Set temperature setting: Adjusting the desired temperature.
- Fan speed setting: Controlling the fan speed.
- Airflow direction setting: Adjusting the louver position (vertical/horizontal) and enabling swing function (vertical/horizontal). Note that airflow direction settings may vary depending on the indoor unit function.
- Timer setting: Setting various timers, including a weekly timer. It's important to note that weekly timer settings from the mobile application and from a wireless/wired remote controller are independent and both will be active if set.
- ECONOMY operation setting: Activating energy-saving modes.
- Room temperature indication: Displaying the current room temperature. For VRF systems, a non-polar 2-wired remote controller connected to the indoor unit with an enabled room temperature sensor is required for this function.
- Air conditioner error e-mail notification: Receiving email alerts for air conditioner errors.
The adapter features two LEDs and a setting button. LED 1 (green) indicates the operation status, while LED 2 (orange) indicates the wireless LAN status. The setting button is used for connecting the adapter to a wireless router.

Maintenance Features:
- Installation Precautions: The manual emphasizes several precautions to ensure safe and proper installation, preventing personal injury, property damage, or product malfunction. These include:
- Disconnecting power before starting work.
- Using only specified accessories and connection cables.
- Avoiding modification of connection cables or use of extension cords.
- Not bundling WLAN adapter wiring with other power or connection cables.
- Discharging static electricity before handling components.
- Ensuring secure connector connections to prevent trouble, heating, or electric shock.
- Performing wiring to prevent water ingress.
- Avoiding direct contact with circuit board parts.
- Optimal Installation Location: The adapter should be installed near the wireless router for stable connection. Certain wall materials may block wireless communication. The manual also lists prohibited installation locations to prevent radio communication interference, such as places exposed to direct sunlight, extreme temperatures, high humidity, near moving parts, inside or on the side of the air conditioner, near microwave ovens, within 1 meter of a TV or radio, within reach of children, near automatic control devices, with oil/vapor/flammable gases, near medical equipment, or where it might get wet.
- Physical Installation Direction: The WLAN adapter must be installed in the correct direction (as shown in the manual) to prevent water from entering the adapter through the wire, which could cause failure. Prohibited installation methods include reverse direction, on the floor, or on a curved surface.
- Prohibited Wiring Configurations: The manual explicitly outlines prohibited wiring configurations, such as group connection of indoor units with wired remote controllers (both 3-wire and 2-wire types), group connection of indoor units without remote controllers, and extending the adapter cable. These restrictions are crucial for proper system operation and safety.
- Firmware Updates: While not explicitly detailed as a user-initiated maintenance feature, the reliance on a mobile app and internet connectivity suggests that firmware updates for the adapter or app may be provided to improve functionality and address issues.
- Support Resources: The manual directs users to the Fujitsu General global support website for the latest product catalogue, applicable indoor units, and WLAN control manuals, ensuring access to up-to-date information.
The Wireless LAN adapter is an integral part of Fujitsu General's smart home ecosystem, providing users with enhanced control and convenience for their air conditioning systems. Adherence to the installation and usage guidelines is essential for optimal performance and longevity of the device.
