DVC 322E VAV Controller for Building Automation

The DVC-V322 is a fully programmable, Native BACnet™ Advanced Application Controller that communicates on an RS-485 LAN using the BACnet MS/TP protocol. This controller is specifically designed for VAV applications and supports the Delta BACstat and LINKnet I/O. The damper actuator assembly is available with or without position feedback. Additional inputs and outputs can be configured as required.


The DVC-V322 is an application-specific controller for VAV and includes an actuator and true differential pressure sensor with integrated housing. The fully programmable DVC-V322 allows GCL+ programs and BACnet objects to be tailored to any VAV application.
