BACnet and Modbus HVAC Interface

This Mitsubishi interface connects a third-party building management system to compatible CITY MULTI, M-Series, or P-Series indoor units. It enables monitoring and control over RS-485 using BACnet MSTP or Modbus RTU protocols. One MelcoBEMS MINI unit is required per indoor unit for operation.

Installation Power and Connector Requirements

The device draws 12VDC power directly from the indoor unit CN105 connector. Verify that the target indoor unit provides this connector and matches the listed compatible model series. It is also compatible with the MAC-333IF connector CN505 IT for specific integration scenarios.

Retrofit for Legacy Protocol Integration

This interface replaces direct proprietary control links when a building management system requires standard BACnet or Modbus communication. The upgrade is worthwhile when centralised automation across multiple indoor units is needed and the existing units are on the supported compatibility list.
