IN776MHI00MO000– Mitsubishi Heavy Industries VRF Gateway (64 Indoor / 12 Outdoor Units)

IN776MHI00MO000 – Mitsubishi Heavy Industries VRF Gateway for KNX, Modbus & BACnet. 

The IN776MHI00MO000 interface is a professional gateway that brings Mitsubishi Heavy Industries VRF air-conditioning systems into the world of advanced building automation. By natively supporting KNX TP-1, Modbus RTU / TCP and BACnet MS/TP / IP, the device enables real-time, bi-directional control and monitoring of up to 64 indoor units and 12 outdoor units from a single DIN-rail enclosure.

Direct connection to the VRF outdoor bus guarantees low latency, while the integrated Auto-Scan routine discovers every indoor and outdoor unit in minutes and automatically generates datapoints inside Intesis MAPS. This slashes commissioning time and eliminates manual addressing errors.

Once online, integrators gain access to more than 70 control and status objects: operating mode, set-point temperature, fan stage, error codes, compressor frequency, energy consumption and service counters. The gateway also exposes advanced BACnet and KNX flags such as occupancy, window-open and energy-saving modes, enabling sophisticated energy-management strategies in hotels, offices and mixed-use buildings.
