Daikin BACnet Modules – Integrate Daikin AC with BMS & SCADA

BACnet communication modules for Daikin air conditioners

In this category, you will find advanced BACnet communication modules designed for Daikin air conditioning systems from the Home, VRV and Skyline series. These modules allow you to seamlessly integrate your air conditioners into building automation systems (BMS) and industrial management systems (SCADA) using either BACnet IP or BACnet MSTP protocol. The BACnet standard is widely used in building automation for its open communication structure and ability to manage HVAC, lighting, and security subsystems in a centralized way.

Using these modules, you can remotely monitor and control various parameters of your air conditioning units, such as temperature, fan speed, power status, and operating mode. In addition, BACnet modules offer enhanced diagnostics capabilities, enabling faster error detection, alarm management, and access to internal variables like filter runtime. All of this helps to improve energy efficiency, reduce operating costs, and extend the lifespan of HVAC equipment.

Compatibility and supported units

The Daikin BACnet modules offered in our store are compatible with a wide range of indoor air conditioning units from the Daikin Home, VRV and Skyline lines. Specific compatibility details can be found in official documentation provided by the manufacturer:

Main features and configuration capabilities

Each BACnet module enables communication with one indoor air conditioner unit and provides access to up to 32 different BACnet objects. These include basic parameters such as setpoint temperature, ambient temperature, fan speed, operating mode, on/off status, and advanced service variables. Communication is done using either BACnet IP (Ethernet) or BACnet MSTP (RS-485), depending on the model and system architecture.

The BACnet modules support both polling (query) and subscription-based (COV – Change of Value) communication, which ensures high performance and scalability in large systems. For installations involving multiple air conditioning units, up to 63 BACnet MSTP modules can be connected to a single BACnet network bus, forming a fully addressable system.

Modules are configured using either DIP-switches (basic settings) or BACnet tools, including the downloadable product database compatible with ETS or vendor-specific software. Thanks to BTL certification (BACnet Testing Laboratories), full interoperability with third-party BACnet controllers and management systems is guaranteed.

Mechanical and electrical properties

Daikin BACnet modules are designed for industrial-grade durability. They support power supply directly from the air conditioner or system bus, eliminating the need for external power. Modules offer 4000VDC isolation between networks, which ensures communication stability even in electromagnetically noisy environments. They can be mounted on a DIN rail (TH35) or directly on the wall using integrated brackets, providing flexibility in cabinet or field installation.

Energy savings and automation

By using BACnet modules, building managers and integrators can implement advanced logic in SCADA and BMS systems, such as automatic switching based on presence sensors, time schedules, or demand-response systems. Control logic can also be synchronized with lighting and shading systems, enhancing occupant comfort while significantly reducing energy usage. Integration of Daikin air conditioners with BACnet allows full visibility into system performance and supports predictive maintenance strategies.

Additionally, remote control via web interfaces or mobile applications is possible when BACnet systems are connected to cloud solutions. This is especially useful for facility managers overseeing multi-site installations or technical service teams requiring access to error logs and unit performance metrics.
