  • 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

Applications

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.
