Daikin to BACnet MS/TP Gateway – Model IN485DAI001I000 for HVAC Integration

IN485DAI001I000 Gateway – Full Integration of Daikin AC Units with BACnet MS/TP Systems. 

The IN485DAI001I000 BACnet gateway enables seamless, bi-directional communication between Daikin domestic air conditioners and BACnet MS/TP automation networks. Designed for fast and efficient integration, the device allows full control and monitoring of Daikin indoor units without the need for external power or configuration software.

This compact gateway connects directly to the AC unit and maps core HVAC functions (mode, fan speed, setpoint temperature), along with advanced diagnostics like error codes and internal variables, into fixed BACnet objects. With onboard DIP switches, installation is simplified to “plug-and-set”, minimizing deployment time.

Key Features of the IN485DAI001I000 BACnet Gateway:

• Certified with BTL mark for full BACnet interoperability
• Supports BACnet MS/TP protocol only
• Configuration via onboard DIP switches – no software required
• Direct connection to Daikin AC unit (RC bus interface)
• Full monitoring and control of AC functions and internal data
• Occupancy logic for energy-efficient operation
• Simultaneous operation via BACnet and Daikin remote controller
• Compact size: 93 × 53 × 58 mm – ideal for DIN rail or wall mounting
• Installation possible inside AC unit for selected Daikin models
• Abstraction of functions into standardized BACnet objects
