Mini-Split and VRF BACnet Interface Control Module Ductless System Integration INT-DMS-BAC-001

The Mini-Split and VRF BACnet Interface Control Module Ductless System Integration (INT-DMS-BAC-001) is a communication gateway designed to integrate compatible ductless mini-split and VRF indoor units into a BACnet-based building automation or management system. This control module translates system operating data and commands between the ductless control platform and the BACnet network, allowing centralized monitoring and limited control of functions such as system status, mode operation, and temperature setpoints based on the connected system architecture. It installs as a hard-wired interface module and connects through low-voltage communication wiring to both the HVAC system and the BAS network. For proper job fit, technicians must verify system compatibility with BACnet integration, confirm supported communication protocols, ensure correct wiring polarity and network addressing, and validate that the indoor units and controllers are approved for external BAS interface. Using a BACnet control module simplifies integration into commercial control environments, reduces the need for multiple standalone controllers, and helps streamline commissioning and ongoing system monitoring while minimizing callbacks related to communication or control conflicts.
