INBACMIT001I000 – Mitsubishi Electric Air Conditioning to BACnet/IP & MS/TP Gateway

Mitsubishi Electric Air Conditioning to BACnet/IP and BACnet MS/TP gateway – 1 indoor unit.

The INBACMIT001I000 gateway from Intesis (HMS Networks) is designed for bidirectional integration of Mitsubishi Electric air conditioning systems with building management systems based on BACnet/IP or BACnet MS/TP. The device enables seamless communication between HVAC equipment and BMS, SCADA or automation controllers, exposing AC unit data as standardized BACnet objects.

The gateway supports both BACnet/IP via Ethernet and BACnet MS/TP via RS-485 (EIA-485), allowing flexible adaptation to different network architectures and project requirements. Air conditioning unit parameters and functions are mapped to fixed BACnet Objects, ensuring predictable data structure and straightforward integration with BACnet-compliant systems.

The INBACMIT001I000 provides full control and monitoring of a single indoor unit, including operating states, alarms, and internal variables. A built-in running hours counter supports maintenance planning and service optimization, while error indication enables quick diagnostics at the BMS level.

To support energy-efficient operation, the gateway includes an occupancy function, allowing HVAC operation to be adapted based on room usage. This function helps reduce energy consumption and operating costs, particularly in office buildings, hotels, educational facilities and commercial spaces.

The air conditioning unit can be controlled simultaneously through BACnet/IP or BACnet MS/TP and the manufacturer’s own remote controller. This ensures system-level integration without limiting local user control or comfort.

Configuration of the gateway is performed via onboard DIP switches, while IP-related settings and device information are available through a built-in web interface. The device does not require an external power supply, as it is powered directly from the AC unit, simplifying installation and reducing wiring complexity. Mounting options include DIN rail or wall mounting, making the gateway suitable for control panels and technical enclosures.
