About the eZV-440
The eZV-440 and eZVP-440 controllers are native BACnet controllers optimized for fan coil
applications. It features line voltage power input with a built-in 24 VAC inverter and line voltage
rated relays eliminating the need for a local control transformer or external relays to switch the fan.
The controller is also designed to be compatible with Delta Controls’ eZNS and DNS-24L network
sensors.
The eZV-440 comes preloaded with algorithms which you configure using a configuration graphic
to match your site’s needs. There are 2 types of eZV-440 controllers: both the configurable (eZV)
and programmable (eZVP) 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.
About This Guide
This application guide introduces the controller and describes the differences between the
configurable and programmable models. The guide also shows you how to use the configuration
graphic in ORCAview 3.40 R3 and higher to set up your eZV-440 controller. The product name
eZV-440 in this guide refers to both the configurable and programmable models unless stated
otherwise.
The ORCAview configuration graphic version referenced in this guide is B-169041.1.
For help with the eZV-440 configuration page in enteliWEB 4.3 and higher, go to the online help in
enteliWEB. enteliWEB users require the applicable object permissions to change the settings on
the configuration page.
The installation guide for the eZV-440 can be found on the eZV-440 product web page on
the Delta Controls Support web site.
Upgrading Firmware
See the release notes of the firmware version you are upgrading to for more information.

About the eZV-440
Object Restriction Settings (ORS)
The Object Restriction Settings (ORS) object allows the user to limit which database objects can be
viewed and edited. This is useful for hiding configuration settings which are not used in day-to-day
operation, to ensure a user cannot inadvertently change the configuration after initial system
commissioning. enteliZONE controllers support permission options of visible, read and write.
However, enteliZONE controllers do not support create or delete permissions as enteliZONE has a
fixed database structure where objects are editable but cannot be created or deleted. enteliZONE
controllers also do not support multiple ORS objects with temporary unlock permissions.
ORS security is turned on and off by locking and unlocking the controller. The ORS is unlocked in
the default database configuration. It must be unlocked in order to configure the controller. If the
controller is in a locked state, a message is displayed asking the user to unlock the controller.
To unlock the controller in ORCAview:
1. In the Navigator tree, right-click on the enteliZONE controller and point to Object Security
and then click Unlock.
2. Enter the unlock username and password. The default username is DELTA and the
password is login.
ORS Troubleshooting
If the controller time does not match the OWS time, the controller cannot be unlocked. To update
the controller time in ORCAview, on the Tools Menu, click Set Controller Time.
Without the correct username and password there is no way to unlock the controller. If the correct
username and password is unavailable, reload a copy of the default database into the controller,
this restores access to the controller, using the default username and password, however any
previous configuration changes will be lost.

About the enteliZONE ORCAview Configuration Graphic
The enteliZONE controller configuration graphic in ORCAview provides a user-friendly interface to
configure the controller’s algorithm and its corresponding objects and IO points. Each time a
change is made to a field or option,ORCAview updates the corresponding object references. The
topic enteliZONE Database Configuration Objects lists the fields and options, and their object
references.
In enteliWEB, the configuration page is available as a tab on the Object List page.
Downloading the ORCAview Configuration Graphic
You can download the configuration graphic from the enteliZONE controller product web page on
the Delta Controls Support web site and install it on your operator workstation.
Installing the ORCAview Configuration Graphic
To install the configuration graphic in ORCAview:
1. On your operator workstation, go to the graphic folder C:\Users\Public\Delta
Controls\3.40\Sites\<site name>\Graphics. The site name refers to the site where the
enteliZONE controller you are configuring resides.
2. Copy and paste the configuration graphic zip file into the Graphics folder.
3. Unzip the file.
There are 7 configuration (.gpc) files associated with the enteliZONE controller. Each file
corresponds to a tab on the configuration graphic. The balancing file is not enabled on the eZFC424R4-24 or eZ-440R4-230 controller.
Opening the ORCAview Configuration Graphic
There are 2 ways to open the configuration graphic in ORCAview. Make sure the configuration
graphic is installed on your operator workstation before attempting any of these steps.

About the enteliZONE ORCAview Configuration Graphic
Method 1 (Recommended)
1. In the left window of the ORCAview navigator, right-click on the enteliZONE controller you
want to configure and click Open.
If this is your first time using the configuration graphic, the DEV object dialog opens.
2. On the Configuration tab, click and browse to the graphics folder and select the Main.gpc file
for the enteliZONE controller. Click OK.
3. In the left window of the ORCAview navigator, right-click on the enteliZONE controller again.
Click Open. Because you have set it up in step 2, the configuration graphic window should
open and will open this way each time you select Open from the right-click menu.
Right-clicking does not work if you have changed the name of the configuration
graphic file or if the Controller Graphic field in the Device object (in the controller
database) has been edited.
Method 2
1. In the left window of the ORCAview navigator, open the Graphics folder and double-click on
one of the configuration files. A new graphic window opens. You can access all the
configuration files from this window.
2. In the numerical field at the top of the window, enter the BACnet address of the enteliZONE
controller you want to configure and click Connect.
Working with the ORCAview Configuration Graphic
This graphic is interactive and dynamic in real-time. When you select an option in a field, other fields
and options are displayed in response to the initial option selected. What this also means is that any
changes made to the fields are saved and applied instantly.
Selecting Between Multiple Controllers
If you have multiple enteliZONE controllers of the same kind on the same network, instead of
opening the configuration graphic individually for each controller in the ORCAview navigator, you
can switch between controllers within the configuration graphic.
When you switch between controllers, any changes made in a previous session will be
saved automatically before you switch to the next controller.
Page 12 of 84 eZV-440 Application Guide
Edition 2.6
To select between multiple controllers:
In the numerical field at the top of the window, enter the BACnet address of the enteliZONE
controller you want to configure and click Connect.
Save to Flash, Save to PC and Load from PC
These buttons are displayed at the top of the configuration graphic dialog. They minimize the need
to switch between the configuration graphic and the ORCAview Navigator when you are working
with multiple controllers.
The Save to Flash button is used to save the controller database to the controller’s flash memory.
The Save to PC button is used to save the controller database .pdb file to your computer.
The Load from PC button is used to load a controller database .pdb file from your computer onto
the enteliZONE controller.
Both Save to PC and Load from PC allow you to save your configuration graphic settings and copy
them onto multiple enteliZONE controllers using ORCAview.
Shortcuts
There is a quick way to open the ORCAview object dialogs by right-clicking on the configured input
and output numbers in the configuration graphic.
In the example below, when you right-click on the number 1 and select Open SpaceTemp_AI1,
the AI1 object dialog opens onscreen.

Differences Between Configurable and Programmable enteliZONE Controllers
This topic describes the main differences between these 2 types of controllers.
Using the ORCAview or enteliWEB configuration page, variables and setpoints are entered into
the algorithm and written to the appropriate preset objects (100 to 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 it is recommended that you use the configuration
page to set up your programmable controller, local programming can be used to overwrite the
algorithm by writing to the objects in the 800 to 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.
Object Type Configurable Programmable
LINKnet objects (LNK) 1 4
Event objects (EV)
Trend Logs (TL) 4 8
Programs (PG) 0 3
Gateway Translation objects (GWT)
(firmware 2.2 and higher)
For a complete list of enteliZONE supported object types and the number of instances allowed for
each object, go to the enteliZONE 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 enteliZONE controller and are numbered LCDx001
and LNKx001 respectively where x is the network sensor’s device address.
0 5
0 4
enteliZONE controllers only support eZNS and BACstat LINKnet network sensors. Other LINKnet
devices like Delta Field Modules (DFM) are not supported.
Page 14 of 84 eZV-440 Application Guide
Edition 2.6
Data Exchange
This section describes how the enteliZONE controllers accept and initiate data exchanges in the
network.
The enteliZONE controller accepts these data exchange requests:
l Poll. The default data exchange type set up in the Data Exchange Settings object (DES) is
Poll. The poll interval can be adjusted in the DES object, at a recommended minimum of 1
second per MS/TP device on a segment.
l Change of Value (Confirmed and Unconfirmed). The enteliZONE controller is limited to
a maximum of 12 subscriptions (Delta Exchange Local or DEL objects).
The controller does not support the Optimized Broadcast and Broadcast Data Exchange request
types. If a controller attempts to subscribe using any of these exchange types, the exchange types
will fail and revert to polling.
The programmable controllers can initiate up to 12 data exchange polling requests (Delta
Exchange Remote or DER objects). Other types of Data Exchange initiating request types are not
supported.
The DES object for the controller lists the number of DER and DEL requests that are in use.
The controller supports Bulk Data Exchange (BDE) but is limited to 2 BDE objects. Each BDE
object can hold up to 12 tag and object entries on the object’s Transmit Entries tab.
For more information about Data Exchange types, go to the George Support knowledge base
article KBA 1813.
Alarming
The programmable controller supports up to 5 EV objects as well as intrinsic alarming on up to 5
input and output points (see below for more information about intrinsic alarming). These EV objects
support these alarm types:
Alarm
Description

Edition 2.6
Page 15 of 84
Configurable and Programmable enteliZONE Controllers
Alarm
Description
Type
Out of
Used to alarm when an analog value varies outside of a set of fixed limits.
Range
The enteliZONE family of controllers does not support Change of Value or Change of Bitstring
alarm types.
Even though the configurable controller versions do not have EV objects, intrinsic alarming can be
enabled on input and output points, specifically analog input (AI), binary input (BI), analog output
(AO) and binary output (BO).
EV objects will send out auto generated messages to notify users about alarms. enteliZONE
controllers do not support alarm acknowledgments.
Custom alarm messages are supported by the following firmware versions:
l eZV-440 controller firmware version 2.1 and higher for EV objects only.
l eZFC-424R4-24 controller firmware version 2.2 and higher for EV objects only.
l eZ-440R4-230 controller firmware version 2.1 and higher for EV objects only.
For more information about how to set up an intrinsic alarm, see the webinar Intrinsic
Alarms in ORCA 3.40 on the Delta Controls support web site.
Trend Logs
A programmable enteliZONE controller supports up to 8 trend logs, 4 of which are user-defined.
The configurable controller version supports 4 trend log objects (TL1 to 4) which are pre configured
in the default database to monitor specific heating and cooling objects. However, all TLs can be
modified to monitor objects other than the default set object. You can also change the method of
data collection (Change of Value or polling) as well as the polling interval. However, fields that
display the maximum and total sample size are read-only.
It is not recommended to use Change of Value for objects that are expected to change at a rate
faster than every 5 seconds. TL objects have a 5-second record limit. Events that occur faster than
this record limit will result in “Log Enabled” or “Log Interrupted” entries that can be hard to interpret.
The default database TL objects are listed in the following table.
Trend Log Monitored Object
1 SpaceTemp (AV1)
2 CurrentHeatSetpoint (AV800)

Trend Log Monitored Object
3 CurrentCoolSetpoint (AV801)
4 HeatCoolLoad (AV802)
5 User-defined
6 User-defined
7 User-defined
8 User-defined
The enteliZONE trend logs also support Historian archiving. The enteliZONE controllers don’t
support buffer full notification events so make sure the Historian update interval is frequent enough
to avoid missing samples.
Programming
In the programmable controller, the 3 programs that exist alongside the configurable algorithm
allow you to either create your own custom algorithm or override portions of the configurable
algorithm to suit your needs. The maximum size of each program is 5 KB.
The programmable controller also allows you to create new I/O, AV, BV and MV objects in the 900999 range for use in your custom program.
Supported GCL+ Programming Functions, Statements and Operators
The Call Statement is not used in the programmable enteliZONE controllers. Unlike other
programmable Delta Controls controllers, the 3 programs in the programmable enteliZONE
controllers are automatically scanned. The scan rate is also designed to be a constant 10
scans/second.
A list of supported and unsupported GCL+ functions and statements for the enteliZONE
programmable controllers is recorded in KBA 2137 on the George Support web site. The
ORCAview and enteliWEB GCL editors are not aware of these limitations, so using an
unsupported function in an enteliZONE programmable controller will not register a syntax error in
these GCL editors.
Overwriting the Algorithm
You can overwrite the algorithm by programming specific objects numbered in the 800 range. For
example, if you want to change how the algorithm determines the occupancy state, you could write
your own GCL+ program to set the occupancy MV800 state.
Your program must write more frequently than every 5 seconds else the factory algorithm will
recapture control.

Displays the password that secures access to the controller’s NFC chip. The
value range is 0 to 65535. The password is stored on the AV96 object.
The Device Password field on the Delta Controls mobile applications must match
the NFC password before any data can be written to the NFC chip.
Turns on or off Derived Network Addressing (DNA) automatic addressing. DNA
is turned on when the box is checked; the BACnet address also becomes readonly. To manually enter a new address, clear the DNA box.
Delta Controls products have the option to use DNA or Derived Network
Addressing, a system of organizing and configuring controllers in a network.
When DNA is enabled, addresses are automatically assigned to a device based
on the BACnet network type and the Delta Controls product type, so that a
device can work out-of-the-box without much set up.

Select the main HVAC system application for this controller. This determines
the algorithm that will be used for the controller.
The options for the eZV-440 are VAV-single duct, VVT and None.
The configurable controller has no functional state until you select an
algorithm.
In a fully programmable controller, when you select an algorithm, you can
override portions of the internal algorithm to suit your needs. See the section
in this guide about overwriting the algorithm. Select None if you want to
program a fully custom sequence of operations. When you select None, the
internal algorithms are disabled and all preconfigured algorithm I/O points and
variables are removed from the default database. Other object types, like AIC,
that were part of the algorithm can be used as is or reconfigured.
If you change an application type for another, the settings of the
previous application type will be deleted. You can save your
controller database before switching application types.
Displays the temperature units used by the controller.
Units
Airflow Units
Child
Controller
(enteliWEB
only)
Displays the airflow units used by the eZV-440 controller. Select between
CFM, l/s or m3/h.
In the configuration graphic, when VVT is selected as the application type, the
units are set to percentages which represent the damper min/max positions.
When VAV is selected as the application type, the AV124 to AV127 objects
and the air flow setpoint will use the units set up in the Airflow Units field.
If this controller reports to a parent controller, select this box. The child
controller polls these variables from its parent controller:
l HeatCoolLoad (AV802)
l OccupancyMode (MV800)
l DemandCtrlVent (AV813)
