About the eZFC-424R4-24
The eZFC-424R4-24 and eZFCP-424R4-24 controllers are native BACnet controllers optimized
for fan coil applications. It has multiple input and output configuration options covering a wide range
of fan coil configurations including single or multi-speed fans, 2-pipe or 4-pipe systems, with or
without change-over. The controller is also designed to be compatible with Delta Controls’ eZNS
and DNS-24L network sensors.
The eZFC-424R4-24 comes preloaded with algorithms which you configure using a configuration
graphic to match your site’s needs. There are 2 types of eZFC-424R4-24 controllers: both the
configurable (eZFC) and programmable (eZFCP) models use the configuration graphic for setup
but only the programmable controller allows you to overwrite the default sequences with General
Control Language (GCL) programming.
You can use ORCAview 3.40R3 and higher or enteliWEB 4.1 and higher to access the
configuration graphic.
