Communication modules for Fujitsu air conditioners – KNX, Modbus, BACnet, WiFi

Communication modules for Fujitsu air conditioners

This category includes communication modules for Fujitsu air conditioners, enabling integration with master control systems and devices communicating via various industrial protocols. These modules allow for remote management of air conditioning systems, enabling quicker fault diagnostics, temperature and power control, as well as access to additional functions that save service time, energy, and reduce equipment wear.

What communication protocols are supported?

Communication modules for Fujitsu air conditioners support integration with various building and industrial systems using the following protocols:

• Fujitsu Modbus RTU module – for PLC and SCADA integration
• Fujitsu KNX TP-1 module – for building automation systems
• Fujitsu BACnet MSTP / BACnet IP module – compatible with BMS platforms
• Fujitsu WiFi module – for mobile and cloud-based applications

Each module enables remote control of key air conditioner parameters, including operating mode, setpoint temperature, fan speed, airflow direction, and night mode. Additionally, they allow for reading the current system status, alarms, and diagnostic data, helping reduce the time needed for service interventions.

All devices are certified according to the relevant protocol standards (e.g. BTL, KNX, CE), and can be configured either locally (e.g. via DIP-switches) or remotely using ETS (for KNX) or dedicated setup software. Depending on the model, the modules support both wall and DIN rail (TH35) mounting.

By utilizing digital communication, the modules not only allow for direct control but also enable automation of HVAC operations based on schedules, occupancy sensors, window sensors, or weather data. Fujitsu modules are more than just communication interfaces – they’re key components of intelligent HVAC and energy-saving ecosystems.
