IN776MHI00SO000 – Interface for Mitsubishi Heavy Industries VRF (16 indoor, 12 outdoor units)

IN776MHI00SO000 – Interface for Mitsubishi Heavy Industries VRF (16 indoor, 12 outdoor units). 

The IN776MHI00SO000 interface is a professional gateway that enables full bidirectional integration of Mitsubishi Heavy Industries VRF systems with home and building automation environments via KNX, Modbus, BACnet, and IP-based systems. Designed specifically for applications requiring advanced control and monitoring, this model supports up to 16 indoor units and 12 outdoor units through a single, unified connection point.

Thanks to its direct access to the VRF communication bus, this interface provides real-time control of AC functionalities such as temperature setpoint, operation mode, fan speed, and status feedback. Moreover, it allows the automation system to access internal variables from both indoor and outdoor units, enabling advanced automation scenarios and intelligent energy management.

This gateway is ideal for smart homes, residential complexes, and commercial buildings where seamless HVAC integration is a priority. With support for multiple communication protocols and simultaneous TCP client connections (up to 6), it ensures compatibility with virtually any modern automation infrastructure.
