Controling device


  • The control electronics are integrated in the FFU housing and contained in the FFU position. An on-site assembly of the electronics is therefore not necessary.
  • The FFU-s can be controlled via a 0-10V input signal as well as via various bus systems (ebm-bus, LON, Modbus). Corresponding control systems from simple speed regulators to PLC controls are available from AFPRO Filters.
