Application

The DVC-V304 is an application-specific controller for VAV and includes an actuator and true differential pressure sensor with integrated housing. The fully programmable DVC-V304 allows GCL+ programs and BACnet objects to be tailored to any VAV application.

Features

• Native BACnet firmware
• BACnet MS/TP communications
• Supports 4 BACstat network sensors on LINKnet for room sensing and control or 2 Delta Field Modules on LINKnet for I/O expansion
• Integrated housing with damper assembly for easy, cost effective installation
• Reliable industry standard actuator (with optional position feedback)
• True differential pressure sensor
• Completely 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 flash loading in the field
• Supports flash loading Modbus upgrades via hardware key
• Derived Network Addressing (DNA) for simple integration into a standard network architecture
• Service port
