INMBSHIT064O000 – Hitachi VRF to Modbus RTU/TCP interface for 64 indoor units

INMBSHIT064O000 – Hitachi VRF to Modbus RTU/TCP interface for 64 indoor units. 

The newer version of this device is IN770AIR00MO000.

The INMBSHIT064O000 by Intesis is a professional gateway developed to ensure seamless integration of Hitachi VRF systems with Modbus RTU and Modbus TCP networks. Supporting up to 64 indoor units, this device is ideal for commercial or industrial installations requiring centralized control and remote monitoring.

This gateway is directly connected to the H-Link communication bus of the outdoor units and allows control and supervision of all indoor units in the system. Beyond basic control functions such as mode, setpoint temperature, fan speed, and on/off status, it also offers access to diagnostic data and internal variables of outdoor units, making it an advanced and robust integration tool.

Configuration and commissioning are done through the intuitive Intesis MAPS software, which provides tools like automatic device discovery, register mapping, and real-time diagnostics. Thanks to this platform, system setup is efficient and errors can be detected and resolved quickly using detailed communication logs and monitoring tools.
