The MMCU is the core of our new digital solution, capable of connecting up to 99 ebm‑papst Modbus-enabled EC fans for streamlined control and monitoring.

Highlights include:

• Auto addressing and reordering: Simply the management of multiple fans.
• User-friendly configuration: Set-up via Wi-Fi hotspot or Ethernet using the built-in webserver interface.
• Real-time data monitoring: Access live data for informed decision making.
• BMS integration: Communicate seamlessly with external Modbus master devices through the BMS port.

The CN1133 can connect, auto address, and re-order up to 99 ebm-papst Modbus enabled EC fans, with software version 5.0 or later using a two-wire plus ground RS485 connection. Configuration can be done using a Wi-Fi hotspot or Ethernet connection with a built-in webserver interface. The BMS port can be used to communicate with an external Modbus master device. The webserver provides real-time monitoring and control data. LTE daughter board enables on-board cloud connection to InSights® dashboard via an external antenna.
