INBACHIS016O000 – Gateway for Hisense VRF systems to BACnet IP/MSTP for 16 indoor units

INBACHIS016O000 – Gateway for Hisense VRF systems to BACnet IP/MSTP for 16 indoor units. 

The newer version of this device is IN770AIR00SO000.

The INBACHIS016O000 gateway by Intesis is a robust industrial-grade communication interface that enables seamless integration between Hisense VRF air conditioning systems and building automation platforms using the BACnet IP or BACnet MS/TP protocol. It is specially designed to serve as a transparent bridge, allowing bi-directional monitoring and control of up to 16 indoor units via BACnet-based BMS, SCADA or PLC systems.

By directly connecting to the H-Link communication bus of the outdoor units, the gateway provides real-time access to both primary HVAC functions (such as on/off control, setpoints, fan speeds) and deeper internal variables (e.g., coil temperatures, fault status, compressor frequency). This makes it an ideal solution for professional HVAC integrators seeking deeper visibility into the VRF operation for energy optimization and remote diagnostics.

Its setup is easily managed through the intuitive Intesis MAPS configuration software. The platform provides powerful tools including:

• Auto-discovery of indoor units
• Custom BACnet mapping with CSV export
• Real-time diagnostic monitoring
• Firmware updates and secure local configuration

With this tool, installers can achieve full configuration in minutes and access a range of diagnostic data that helps reduce downtime and improve commissioning quality.

Thanks to dual BACnet support (IP & MS/TP), the INBACHIS016O000 offers flexibility for modern networks or legacy RS-485 infrastructures. It also features full galvanic isolation (1500 VDC) between ports to enhance system protection.

This compact device is perfectly suited for DIN rail or wall-mounting, making it ideal for electrical cabinets or confined technical spaces. It's powered with a wide voltage range (9–36VDC or 24VAC) ensuring compatibility with existing power sources in most commercial installations.
