Key features
Fujitsu Airstage WLAN Adaptor UTY-TFSXJ3 – Wi-Fi Control Accessory
Fujitsu Airstage WLAN Adaptor (UTY-TFSXJ3) enables convenient Wi-Fi connectivity for compatible Fujitsu air conditioning systems, allowing remote control and monitoring via smartphone or tablet for improved system management and comfort.
Central Control System Integration (Optional)
For enhanced building management, the system can link with a range of central control platforms. By integrating via optional MODBUS or KNX interfaces, users can centrally monitor and control not only air conditioning but also other facility equipment, providing a unified and efficient control solution.
Compact & Lightweight Design for Easy Installation
The indoor and outdoor units feature a reduced chassis size and lower overall weight, enabling easier handling and installation while remaining suitable for high static pressure ducted applications.
Low Noise Operation
Slanted top corners help reduce turbulent airflow, while the use of a plastic casing and plastic fan minimises vibration and airflow noise for quieter system operation. This creates a medium noise level of 40 dB(A) for the high static R410A model and 43 dB(A) for the R32 models.
