INMBSHIS016O000 – Hisense VRF to Modbus RTU/TCP Gateway for 16 indoor units

INMBSHIS016O000 – Hisense VRF to Modbus RTU/TCP Gateway for 16 indoor units. 

The newer version of this device is IN770AIR00SO000

The INMBSHIS016O000 gateway is specifically developed for bidirectional integration of Hisense VRF air conditioning systems with Modbus-based automation systems. This includes BMS platforms, SCADA systems, PLCs, or any other device acting as a Modbus RTU or Modbus TCP Master.

The device connects directly to the H-Link communication bus of the outdoor units and enables the control and supervision of up to 16 indoor units. Users gain access to core AC functions such as temperature setpoint, mode, fan speed, and ON/OFF status, as well as to several internal parameters of the outdoor units for advanced diagnostics.

Configuration is done using the powerful Intesis MAPS software, which provides flexible setup options, user-defined mapping, and a built-in scan function to automatically detect connected indoor units. This significantly reduces commissioning time and allows quick deployment. A robust diagnostic tool within Intesis MAPS simplifies troubleshooting during installation and maintenance.
