About the eZV-440
The eZV-440 and eZVP-440 controllers are native BACnet controllers with an integrated airflow
sensor and damper actuator for VAV applications, including multi-stage reheat with analog,
binary or floating control, and series or parallel fan boxes. The controller is also designed to be
compatible with Delta Controls’ eZNS and DNS-24L network sensors.
The eZV-440 controller comes pre-loaded with an algorithm which you configure to your site’s
needs using a configuration graphic. There are 2 types of eZV-440 controllers: both the
configurable (eZV) and programmable (eZVP) models use the configuration graphic for set up
but only the programmable controller allows you to create more complex control sequences
with General Control Language (GCL) programming.
