Configurable and Programmable eZV Controllers
The eZV-440 controller is designed to work predictably for typical VAV and VVT applications with
minimal setup. Using the configuration graphic, objects and setpoints are entered into the
algorithm and written to the appropriate preset objects (100-199 range, 1000+ range for
LINKnet device configuration) in the factory controller database.
In the configurable type of controllers, there are no program (PG) objects. In the programmable
controllers, even though you could still use the configuration graphic to set up your
programmable controller, local programming can be used to overwrite the algorithm
by writing
to the objects in the 800-899 range.
There is a limit to the number of specific object types in these controllers. The number limits
are summarized in the table below. You cannot exceed this number by creating any new objects.
For a complete list of eZONE supported object types and number of instances allowed for each
object, go to the eZONE overview page
on the Delta Controls Support web site.
LINKnet Devices
Configurable controllers can only connect to 1 LINKnet device at a time. This LINKnet device
has to have a device address of “1” in order for it to work with the controller algorithm. Multiple
LINKnet devices (up to 4) are only supported by the programmable controllers.
LCD and LINKnet objects are located on the eZV-440 controller and are numbered LCDx001 and
LNKx001 respectively where x is the network sensor’s device address.
enteliZONE controllers only support eZNS and BACstat LINKnet network sensors. Other
LINKnet devices like Delta Field Modules (DFM) are not supported.
Data Exchange
This section describes how the eZV-440 controllers accept and initiate data exchanges in the
network.
The eZV-440 controller accepts these data exchange requests:
