QCA-V1322E Application Controller

COSYS Building Controls


Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.


  • Native BACnet firmware
  • Fully programmable in GCL+
  • BACnet IP/BACnet over Ethernet Main LAN communications
  • Supports a RS-485 subLAN of LINKnet smart network sensors and I/O expansion modulesl
  • Direct Mount housing integrates controller, damper actuator and airflow sensor into a single package for easy, cost effective installation
  • Firmware upgrade and database load/save over the network
  • Optional field upgrade to Modbus® RTU with hardware key
  • Service port
  • LED status indicators of outputs, communication ports and CPU Scan Status
  • Local Trending and Alarming


The QCA-V223E is designed for VAV applications and includes an on-board actuator and true differential pressure sensor in a direct mount integrated housing.
The fully programmable QCA-V223E allows GCL+ programs and BACnet objects to be tailored to any VAV application.
