Description

The eZV-440 is a native BACnet® controller with an integrated airflow sensor and damper actuator for VAV applications, available in both configurable and hybrid-programmable versions.

The eZV communicates using BACnet MS/TP on its RS-485 main LAN port. It also has a RS-485 subLAN port for the optional addition of a Delta LINKnet network sensor(s).

eZV-440

Application

The eZV-440 covers a wide range of VAV configurations including multi-stage reheat with analog, binary or floating control, and series or parallel fan boxes.

The eZV-440 comes pre-loaded with a simple-to-configure factory algorithm; the hybrid-programmable eZVP-440 option allows customization of the built-in algorithms.  

Features

Native BACnet firmware allows easy integration with any BACnet system

Local scheduling, trending, and alarming support

Built-in configurable VAV algorithms for quick setup and commissioning

Optional hybrid-programmable option allows customization for non-standard sequences or repurposing unused I/O

Universal outputs provide flexibility for any combination of analog, binary, or floating output stages

Firmware upgrade and database load / save over the network

RS-485 subLAN supports up to 4 DNS or eZNS LINKnet network sensors
