BACnet communication modules for Fujitsu air conditioners
This category includes BACnet communication modules designed for integration of Fujitsu VRF (Variable Refrigerant Flow) and RAC (Room Air Conditioner) indoor units with centralized automation systems, such as Building Management Systems (BMS) or SCADA platforms. These modules facilitate seamless communication using BACnet IP or BACnet MSTP protocol and provide extensive control capabilities that extend the functionality of Fujitsu HVAC installations.
The use of BACnet gateways significantly simplifies remote monitoring and control. Users gain access to temperature setpoints, operation modes, fan speed, and alarm status directly from the supervisory system. This allows facility managers to quickly diagnose malfunctions, optimize energy consumption, and ensure comfort across multiple zones from a central interface. As a result, maintenance costs are reduced, system uptime is improved, and energy efficiency is maximized.
These modules are essential for commercial buildings, hotels, schools, and hospitals where integration of HVAC with lighting, security, and fire detection is crucial for unified facility management. Fujitsu BACnet modules allow air conditioning units to become part of a comprehensive automation environment, enabling intelligent coordination of building resources.
The list of compatible indoor units is available in the official documentation – COMPATIBILITY LIST.
Features and functions of Fujitsu BACnet communication modules
Each module allows direct connection of one indoor unit from the RAC or VRF range. The gateway exposes up to 32 signals (BACnet objects) per unit, including power status, operating mode, ambient temperature, set temperature, fan speed, error codes, and more. The device supports both read and write commands and utilizes either polling or Change of Value (COV) for real-time updates.
BACnet MSTP modules can be daisy-chained over RS-485 lines, with support for up to 63 units on a single network segment. This reduces cabling complexity and makes system expansion easy. IP versions can be integrated via BACnet/IP, suitable for modern infrastructures with structured cabling and switches.
Configuration is simple and flexible. DIP-switches provide basic setup, while advanced configuration is possible via the network using standard BACnet tools. The modules can operate in parallel with the original Fujitsu remote control, maintaining local control for end-users even when the BMS has master access.
The devices are powered directly by the indoor unit, requiring no external power supply. They are protected by electrical isolation up to 4000 VDC, ensuring safe operation in electrically noisy environments. Mounting options include DIN rail (TH35) and wall mounting, offering flexibility for control panels and utility spaces.
All gateways in this category are BTL certified, meeting BACnet standard compliance and ensuring full interoperability with third-party BACnet devices. Whether integrating with Schneider Electric, Honeywell, or Siemens systems, these modules provide reliable and standardized communication.
Applications and benefits
BACnet communication modules are ideal for HVAC contractors, BMS integrators, and facility owners who want to monitor and control HVAC assets across large or distributed buildings. Whether it's an office tower or a data center, centralized HVAC supervision helps identify inefficiencies, track trends in power consumption, and respond to critical alarms.
By integrating Fujitsu air conditioners with a BMS platform, you enable automation based on occupancy sensors, scheduling logic, or energy demand profiles. This not only enhances comfort and usability but also contributes to certification under green building standards like LEED or BREEAM.
