Main Benefits

Dedicated to Air Handling Unit (AHU) machines, this architecture provides the best solution for AHU that require modularity, flexibility and integrated controls. This architecture implementation as a dedicated control panel combine circuit breakers, variable speed drives for fans, sensors and a controller with IO modules that bring modularity and flexibility. Native connectivity for the AHU is available through Modbus or connectivity to various BMS networks (BACnet MS/TP, BACnet IP, Modbus TCP....) through the optional communication module. Moreover, the Modicon M168 programmable logic controller provides dedicated functions to enhance energy efficient controls of your AHU.



Modularity and flexibility

  • High level of modularity with M168 IO base+ I/O expansion module allow to address a wide range of AHU configurations


Save 50 % in design time and installation time

  • Fully integrated control panel from circuit breakers, variable speed drives to sensors and actuators
  • Fully customizable application programs available for several AHU configurations
  • Predefined CAD diagrams and complete system user guide


Energy efficiency

  • Energy efficient solutions for discharge & room temperature control plus variable air flow management with Varable Speed Drive


Openness

  • Plug & Play connectivity to the more commonly used BMS protocols (Modbus, BACnet MS/TP, BACnet IP, LON)
