The IQ411 and IQ412 are the first two models in a new generation of BEMS controller. Though small in size, the Trend IQ411 and IQ412 offer a combination of advanced capabilities not found on any other building services controller, even much larger ones. The versatile new units - which incorporate a range of features that simplify installation, engineering and commissioning - are ideal for energy efficient, highly distributed local control of services such as underfloor heating, natural ventilation, small air handlers and air conditioning terminal units.

The IQ411 and IQ412 have also been designed as perfect drop-in replacements for Trend IQ21x and IQ7x series controllers that may be nearing the end of their operational lives. Swapping one controller for another - including uploading/reloading the control strategy - takes five minutes or less.

Key features:

  • Ethernet 10/100 Mbps main network with TCP/IP protocol
  • Trend current loop LAN option
  • BACnet over IP option
  • Small footprint with DIN rail mounting
  • RS232 and USB local supervisor ports
  • Soft addressing with Barcode addressing
  • Features to directly replace IQ21x, and IQ7x series controllers
