KNX Communication Modules for Fujitsu Air Conditioners

KNX communication modules for Fujitsu air conditioners

This category features advanced KNX communication modules designed specifically for Fujitsu air conditioners, including the RAC and VRF series as well as models with built-in infrared (IR) receivers. These modules allow seamless integration with building management systems (BMS) and SCADA infrastructure via the standardized KNX TP-1 (EIB) protocol. By using these gateways, users gain the ability to remotely control and monitor air conditioning systems, which translates to increased energy efficiency, easier fault diagnostics, and extended device longevity.

Remote management enables building administrators to track performance parameters such as indoor temperature, fan speed, and operating mode in real time. This allows faster responses to malfunctions or deviations from optimal operation, without needing physical access to the AC units. By reducing energy waste and maintenance costs, KNX integration becomes a vital tool in sustainable building design.

The list of compatible indoor air conditioning units can be found in these documentation files: Fujitsu, General, Fuji Electric, Hiyasu.

Functions and features of Fujitsu KNX communication modules

Fujitsu KNX gateways are compact, easy to install, and designed for flexible configuration. They support various KNX datapoint types (DPT), enabling full bi-directional communication between the air conditioning unit and the KNX network. These modules can be configured to interpret control commands such as operating mode, temperature setpoint, fan speed, vane position, and remote lock status.

In addition to standard control functionality, modules dedicated to VRF and SKY Air systems support enhanced modes such as:

• Powerful mode for rapid cooling or heating
• Economy mode for energy-saving performance
• Additional Heating or Cooling
• Sleep mode when windows are detected open
• Occupancy detection and management

These functions are essential for automation systems aiming to optimize climate control based on presence, external weather conditions, or energy-saving strategies.

Each module allows up to five custom scenes to be stored and triggered directly via the KNX bus. These scenes can combine different parameters — such as cooling mode, temperature, fan speed, and vane angle — and be switched by toggles, motion sensors, or schedules. This helps implement personalized climate control strategies in offices, hotels, conference rooms, or smart homes.

Moreover, modules come equipped with four potential-free binary inputs that allow direct integration of external sensors and buttons. These inputs can be freely programmed via ETS software to control not only HVAC systems but also lighting, blinds, or alarm triggers, expanding the scope of the KNX infrastructure without additional controllers.

The configuration process is straightforward through the ETS database provided by the manufacturer. The gateway ensures maximum compatibility by supporting multiple KNX DPTs, as well as offering full KNX certification. This makes it compatible with any certified KNX system components available on the market — regardless of the brand or function.

Installation options include DIN rail (TH35) mounting or wall mounting, with power supplied directly from the air conditioning unit, removing the need for an external power source. Thanks to its plug-and-play design, integration into existing or new KNX systems is seamless, and the modular design allows future upgrades or changes with minimal effort.
