Delta Controls eZV-440 VAV Controller

The eZV-440 is a native BACnet controller designed for VAV applications. It features an integrated airflow sensor and damper actuator, and is available in both configurable and fully programmable versions.

Description

The eZV-440 controller integrates an airflow sensor and damper actuator for VAV applications. It is available in configurable and fully programmable models. The controller communicates via BACnet MS/TP on its RS-485 main LAN port and also includes an RS-485 subLAN port for connecting enteliZONE or BACstat smart network sensors.

It also indicates power connections (24 VAC Power) and compliance markings (CE, FCC Class B, EAC, C-UL Listed, UL 916 Listed, BTL Listed).

Application

The eZV-440 is suitable for a wide range of VAV configurations, including multi-stage reheat with analog, binary, or floating control, and series or parallel fan boxes. It includes built-in algorithms for easy configuration of typical VAV/VVT applications. The eZVP-440, a fully programmable model, allows for custom zone programs or modification of built-in algorithms.
