INBACACA004I0000 – Bosch VRF to BACnet IP/MSTP Gateway for 4 Indoor Units

INBACACA004I0000 – Bosch VRF to BACnet IP/MSTP Gateway for 4 Indoor Units. 

The INBACACA004I0000 gateway provides seamless bidirectional integration between Bosch Commercial and VRF HVAC systems and any BACnet-compatible controller, including BMS, SCADA, and PLC platforms. This industrial-grade device enables precise control and monitoring of up to 4 indoor units and 1 outdoor unit, making it an optimal solution for commercial buildings where BACnet protocol is the foundation for interoperability.

Thanks to its native support for BACnet/IP and BACnet MSTP, the gateway ensures maximum flexibility in integration with a wide range of automation networks. Real-time communication is achieved through direct access to the VRF system’s internal bus, ensuring accurate and up-to-date status feedback. Configuration is done via the Intesis MAPS platform – a powerful tool that simplifies project setup, diagnostics, and firmware updates.
