Optional BMS Interfaces for Mitsubishi AE‑400

The AE‑400 (and AE‑400/EW‑C50 family) does not expose native BACnet or Modbus directly from the base unit. BMS integration is achieved using optional Mitsubishi Electric interface modules connected to M‑NET or via the AE controller layer (Yet to be released)

1. BACnet® Interface (M‑NET based)

BAC‑HD150

  • Protocol: BACnet/IP

  • Connection: Direct to M‑NET

  • Role: Exposes indoor unit objects (status, setpoints, alarms, modes) as BACnet objects

  • Use case: Large or enterprise BMS platforms (Trend, Tridium, Siemens, etc.)

  • Limitation: Focused on HVAC objects only (not full AE schedule logic)
