DVC-V304
HVAC VAV Controller
Overview
DVC-V304 is a programmable native BACnet advanced application controller communicating on an RS-485 LAN using the BACnet MS/TP protocol.
This controller is specially designed for VAV applications and supports Delta BACstat and LINKnet I/O. Damper actuator assemblies are available with or without position feedback. Additional inputs and outputs can be configured as required.
Feature
  • Supports 4 BACstat network sensors on LINKnet or 2 Delta Field Modules for I/O expansion
  • Integrated housing with damper assembly for easy and economical installation
  • Reliable industry-standard actuator with optional position feedback
  • True differential pressure sensor
  • Fully programmable in GCL+
  • Application database can be flash-loaded over the network
  • Controller firmware can be flash-loaded over the network
  • Supports Modbus capability via field flash loading
  • Supports flash-load Modbus upgrade via hardware key
  • Derived Network Addressing (DNA) for easy integration
  • Service port
