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 Modbus Display & Control (MDC) is a device with two RS485 Modbus ports, a keypad for setting parameters/navigating and a display to view the status of the connected fans. The RS485 Master port connects to up to 100 Modbus EC fans and the RS485 Slave port allows an interface to a higher-level Modbus Master device e.g. BMS or IoT dataloggers if required. The MDC has its own “fan auto-addressing” feature to ease installation and commissioning, and supports four different operating modes.

The demand ventilation controller (DVC) is designed specifically for industrial/commercial applications. The controller is mains powered, varies the speed of single/multiple fans and is suitable for all ebm‑papst EC 0-10V and most PWM open collector speed controllable fans.
