About the eZNT-WiThe Delta Controls eZNx line includes the following products:

l eZNS network sensor (Delta LINKnet)l eZNT programmable thermostat with local I/O (BACnet MS/TP)l eZNT-Wi programmable thermostat with local I/O (BACnet/IP over Wi-Fi)l eZNTW programmable thermostat with EnOcean (BACnet MS/TP)l eZNTW-Wi programmable thermostat with EnOcean (BACnet/IP over Wi-Fi)

The eZNT-Wi is an advanced BACnet thermostat that expands the enteliZONEthermostat product line. It is fully programmable and equipped with local I/O andWi-Fi wireless network connectivity. The Wi-Fi supports WPA2-AES security(WPA2 is a common name for the IEEE 802.11i-2004 standard). The unit supportsIEEE 802.11b/g/n at 2.4 GHz. The Wi-Fi range is approximately 30 m (100 ft),assuming the walls and furniture are typical and there are no high voltage powerlines nearby.

The eZNT-Wi thermostat is a BACnet/IP wireless Wi-Fi product that is capable ofcontrolling basic unitary equipment. This product supports up to four LINKnetdevices with a limit of two Delta 4xx LINKnet devices.

While the eZNT-Wi has an onboard real-time clock for scheduling, it does not havea battery backup and relies on other system-level controllers for power up andperiodic time synchronization.

The unit includes a standard temperature sensor with optional humidity, CO2 andmotion sensors, and offers a choice of backlight colors that provide additionaluser feedback and aesthetic appeal. Wi-Fi network connectivity avoids the needfor wiring and increases flexibility of installation. In addition, the eZNT-Wi's built-in NFC chip enables installers to use NFC-enabled mobile devices to configure thethermostat.

The eZNT-Wi includes a new CO2 sensor that mounts in a horizontal orientation onthe circuit board. This removes the need to have a backplate with a protrusion intothe electrical box, making wiring the eZNT-Wi much simpler.

Typical eZNT-Wi ApplicationsThe eZNT enteliZONE controller is designed for a wide range of sensingapplications, from basic temperature monitoring to indoor air quality andoccupancy sensing. It can control basic zone hardware such as fan coils, heatpumps, small networked RTUs, unit ventilators, unit heaters, and other equipment

Overview: Wi-Fi ConceptsThe eZNT-Wi offers multiple ways to configure a unit and establishcommunications. This BACnet-capable thermostat can be quickly configuredusing an NFC-enabled mobile device. enteliWEB provides the main way toconfigure related objects and to define a custom configuration if required. EacheZNT-Wi includes its own embedded configuration webpage.

The eZNT-Wi connects to enteliWEB using a wireless BACnet/IP Wi-Fi connectionand has a single onboard 10 kΩ input. The eZNT-Wi includes a radio module thatis IEEE 802.11b/g/n compliant and meets Wi-Fi Alliance certificationrequirements. All modules are certified for US/Canada (FCC /IC), Europe (ETSI),and Japan (TELEC).

The eZNT-Wi's input/output capability is based on local wired connections to enddevices. In addition, the eZNT-Wi provides LINKnet support.

With firmware 3.40R3.1.3 or later, the router (rOU) menu item in the on-screenconfiguration menu displays the Wi-Fi signal strength by displaying 0 (very weak)to 5 (very strong) curved bars. A signal strength of better than -70 dB (2 bars) isrecommended. The signal strength indication can help you find a suitable locationto install the device. The RSSI Wi-Fi signal strength in dB shows on the display bydefault. When the thermostat is connected to a wireless network, the temperaturereading in degC shows on line2 and the RSSI shows on line3 of the display. Inaddition, when a stat is powered up without a database, the Wi-Fi signal strengthshows on line3 of the display.

Wi-Fi PasswordsWi-Fi configuration involves a number of device names/passwords and it is easy toget confused. Some passwords are fixed and you cannot change them, whileothers are directly editable. You need to track and record passwords and otherdevice and network information. You can return an eZNT-Wi to its default state byfirst saving the database and then using the Run/Clear jumper to return to thedefault database. Be sure to put the jumper back in the Run position. See theClear Database topic in the Database Operations section to put a controller backinto the default factory state procedure.

The following table shows the passwords that you typically need when configuringWi-Fi:

WirelessRouter(s)

You need to track andrecord the Router Name(SSID) and the passwordfor each router. TheNetBuilder app lets youenter the routerpassword. However,NetBuilder does not readthe password from NFC.

Wi-Fi ModesThere are two modes of Wi-Fi that allow configuration and connection:

l The eZNT-Wi acts as a Host Access Point (AP) where it has its own routerSSID. After configuration, the AP mode is inactive.

l The eZNT-Wi acts as a client where it connects to a Wi-Fi router. This iscalled Client Station (Stn) mode. Other devices can communicate with thethermostat through the Wi-Fi router via BACnet/IP.




When a new thermostat with Wi-Fi is powered up, it starts in dual mode, whichcombines the Host Access Point mode and Client Station mode. Host Access Pointmode allows a direct connection to a phone or laptop/PC that is enabled as a Wi-Ficlient. In the AP host mode (Access Point), a thermostat acts as a host for 30minutes after the last activity. At the same time, the wireless thermostat alsofunctions in the Client Station mode and continues to communicate after the HostAccess Point mode shuts off.

You can connect with enteliWEB in dual mode but the connection isextremely slow. When AP mode turns off and only station client mode isactive, the enteliWEB connection is much faster.

The intent of the temporary dual Host Access Point (AP) and Client Station modesis to provide a temporary configuration and communication interface. This mode isinitially used to notify the web client that the station was successful in joining anetwork. Dual mode is the default behavior on a new eZNT-Wi or after a reset tothe factory default database using the Run/Clear jumper. If a eZNT-Wi thermostatwas previously on the network, it remembers the previous connection unless youperform the Run/Clear procedure.

MAC Address DefaultsAn eZNT-Wi in AP mode might show an SSID such as eZNT-447F in the wirelessnetwork connections list. You can choose this SSID (e.g., eZNT-447F) from your PCor mobile device to make a connection in AP Host mode.

Each eZNT-Wi has two unique MAC addresses:


l AP Host mode Wi-Fi adapter (IPS2) (e.g., 00:40:AE:06:44:7F)l Regular Client Station mode with BACnet over UDP/IP adapter (IPS1) (e.g.,00:40:AE:06:44:7E) (AP Host Mode - 1)

AP Host Mode (IPS2)The last 4 digits of the AP mode adapter MAC address are the last 4 digits in thedevice SSID (e.g., eZNT). The last four digits of the AP mode hex MAC addressshows up in the LCD display when a wireless thermostat is powered up (e.g.,447F).

The IPS2 object shows the AP Host mode MAC address in its description field.

Client Station Mode (IPS1)The station mode adapter MAC address is the MAC address used if your IT groupwants to whitelist wireless devices based on their MAC addresses. The IPS1 objectshows the station mode MAC address in its description field. This address isalways one less than the MAC address of the AP mode adapter.

Default Device AddressThe default device address is formed by adding the last four hex digits of the APmode hex address minus 1 (AP Mode hex – 1) expressed as a decimal value to thebase BACnet address of the device (4,100,000). For example:

0x447E = (0x447F – 1)17534 (Decimal) == 0x447E (Hex)17534 + 4,100,000 = 4,117,534

Wi-Fi SecurityInitially, the eZNT-Wi powers up in dual mode with both Host Access Point (AP)and Client Station modes active. For security reasons, the AP mode turns offautomatically if no activity occurs for 30 minutes. The AP mode is intended forinitial configuration of a wireless thermostat.

The Wi-Fi security mode supports WPA2-AES security. The unit supports IEEE802.11b/g/n at 2.4 GHz.


Workflow: Wi-Fi Setup for eZNT-WiThe eZNT-Wi offers the following Wi-Fi configuration options:

For more details, see Working with the On-Screen Configuration Menu.

NetBuilder AppUsing the NetBuilder app, you can set Wi-Fi and device settings. The stat does notneed to be powered up or connected to the network to work with the app.NetBuilder handles DHCP only. If you want to set up a static IP address, you mustuse the configuration webpage or enteliWEB (make sure the DHCP checkbox iscleared in the app).

The eZNT-Wi requires the NetBuilder v3.20.005 or higher. Tap the menuicon in the top right area of the app screen and tap About to see versioninformation.

Each device has a unique SSID and a common default password. The NetBuilderapp uses the same password as the on-screen configuration menu. The passwordmay be the default value but it is also possible that someone changed thepassword for the on-screen configuration menu.

AV531 contains the NFC Password which is shared with the thermostat'son-screen configuration menu. To work with the configuration menu, thepassword must contain only 1s and/or 0s.

The app may be used on any Android phone or tablet equipped with NFCtechnology. Apple iOS is not currently supported. You can download theNetBuilder and Stat Configurator apps from George Support (a Delta ControlsPassport account is required).


Set Wi-Fi Configuration and Device Settings Using the NetBuilderAppThe NetBuilder app focuses on setting the network settings for Wi-Fi UDP/IP, andalso specifies the device address. The thermostat does not need power for the

NFC feature to work. You can configure a thermostat while it is still in its shippingbox.

A typical approach is to read the configuration data from an initialNFC thermostat, modify the network configuration once, set the device address,and then transfer the settings to another device. For the next unit, change thedevice address and then transfer the settings to that device, and so on.

To configure multiple eZNT-Wi thermostats using NetBuilder:

1. NFC Tap in and type the password. See NFC Tap and Read the ConfigurationData content in Details: Using Android NFC Apps with enteliZONEThermostats eZNx. Click More… to see the Wi-Fi configuration page.




2. Set the Wi-Fi fields as required. The default SSID is Leif_eZNTW-2.4.


3. If necessary, scroll down to see all the available Wi-Fi settings, includingnetwork number. Return to the main screen and confirm the device address.




4. On the main screen, tap TRANSFER and place over a target device to writethe settings.

5. Confirm that a Successful: Write complete message displays.


6. Increment the device address.

7. For the next stat, tap the TRANSFER button again, place your NFC deviceover the target thermostat, and repeat the process.


Configuration WebpageEach eZNT-Wi thermostat contains an internal web server, which provides awebpage for configuring Wi-Fi communication settings for that specific unit. USBmode must be enabled for the web server to work (it is enabled by default).




To access the configuration webpage via Client Station mode, you need toknow the exact IP address of the wireless thermostat connection(contained in IPS1) in the Wi-Fi network. To access via AP mode, use192.168.124.1 The default Username (ADMIN) and Password (ADMIN) arefrom SUA2.

The webpage interface allows a field tech to perform all the initial setup andconfiguration of eZNT-Wi connected devices without using enteliWEB orORCAview.

Connect Using AP Host Access (Initial Setup)1. Log in to an eZNT-Wi by selecting its SSID from the list shown for the Wi-Fi

router on a laptop. The default password is DeltaControls.

For example, select the router entry for this particular unit: e.g., eZNTW-447F. Ensure that there is no connection to the internet.

2. Connect your web browser to http://192.168.124.1.3. AP Host Mode provides a limited and temporary connection to the wireless

stat using its assigned IP address.4. The following figure shows the AP Host mode (IPS2) for the IP and


Description tab.

Connect Using Client Station Mode (Normal Connection After InitialSetup)Connect your web browser to the IP address of the eZNT-Wi (IPS1). This IP is onlyknown if the initial setup using AP Mode is already completed. In AP mode, theMAC address ends in 447F. Client Station mode (IPS1) is used for normaloperation and has a MAC address that ends with 447E which is one less than theMAC used for AP Host mode.




Configuration WebpageThe eZNT-Wi configuration webpage has the following sections:

l Device Name and Device Addressl Internal AP Settingsl Wi-Fi Settingsl BACnet Network Settingl Device Info

Click on a section heading to collapse or expand it.

When you make any changes to the fields on this webpage, you need to click Savein the upper right area of the page. Otherwise, your changes will be lost.

You need to connect with the embedded web page included in eachwireless thermostat. Make sure your computer does not have internetaccess through an unintended wired or wireless connection. If yourcomputer has connectivity to the internet, you will see an externalwebpage which is not what you need to configure a particular wirelessthermostat.

The following figure shows the embedded web server page for the device withaddress 4109097. The other sections of the page are collapsed. You can click on asection heading to expand or collapse it.


The top of the webpage displays the Device Name, Device Address and the SSID(router network name). The AP Mode (Host Access Point) must be active to getthis webpage.

The default AP Mode password is DeltaControls. The password can be changed bytyping the new password in the password field of IPS2. As you click Save, you mustselect “Commit Settings” from the Command choices on the Internet ProtocolSettings (IPS2) object to confirm the change. This action is only required if youmake the change through the enteliWEB object page. The change is applied thenext time that AP mode is re-enabled.

The following topic shows the relationship between SSID and the Device Addressshowing in the previous figure.




Calculate the Device AddressIf the AP MAC address of an eZNT-Wi is 00:40:AE:BB:23:8A, then the decimalvalue of the last four hex digits 23 8A is 9098. The unique device address is then:

Station MAC address = (AP MAC address -1)0x2380 = (0x238A-1)9097 decimal == 0x2380 hex4100000 + 9097 = 4109097

The device address in decimal is 4109097 as shown in the previous figure.

Each eZNT-Wi unit has two Ethernet MAC addresses:l MAC address for Station Mode (IPS1 shows in description field)l MAC address for Access Point Mode (IPS2 shows in description field)

The device address calculation is based on the Station Mode MAC. The MACaddress is displayed in the IPS object description field.

Enable/Disable AP Mode (Host Access Point)AP Mode can also be turned On/Off via the on-screen display Configuration Menuor enteliWEB.

1. Change the AP Mode field in the Internal AP Setting section of theConfiguration webpage.

2. Click the Save button in the upper right area of the page.

IP Address RecommendationsIt is expected that most sites will use DHCP addressing, with static addressingspecified in the router. In some cases, however, static addresses may be used.You should be able to obtain these from the site's IT admin.

With DHCP addressing, the eZNT-Wi requires the use of DHCPreservation, where a DHCP assigned address is permanently reserved foreach eZNT-Wi device.

Wi-Fi SettingsThe configuration webpage provides a means to define either a DHCP or static IPaddress Wi-Fi connection.


Select the router network name from the SSID field drop-down list. It helps tokeep a list of Wi-Fi routers and wireless devices on a site.

If the required Wi-Fi router is not currently visible, choose Other… to manuallyenter the missing SSID. Typically, this could happen when you are setting upwireless thermostats offsite without the site Wi-Fi router, or if the Wi-Fi router isset to not broadcast its SSID (hidden). Sometimes, a router is available but notshown in the list of displayed SSIDs as many active routers are in the space. Inthese situations, you need to choose Other and manually enter the SSID.

To add a new network SSID to the SSID field drop-down list:

1. Click Other… at the end of the SSID list. The Add Network dialog opens.2. Enter the SSID and click Connect.




To set up DHCP:

1. Select the router network name in the SSID field.2. Select DHCP in the Assignment field.3. Click Save button.

To set up static IP addressing:

1. Select the router network name in the SSID field.2. Select Static in the Assignment field.


3. Specify the static IP address, subnet mask, gateway, and DNS serversettings.

4. Click Save.

BACnet (LINKnet) Network SettingsThe settings in the BACnet Network Setting section of the configuration pageactually relate to LINKnet configuration, as eZNT-Wi models can support up tofour LINKnet devices with a maximum of two DFM-4xx devices. DFM-16xx devicesare not supported. See the eZNT-Wi Installation Guides for more information.

To set up LINKnet I/O communications on a Wi-Fi thermostat:

1. From an eZNT-Wi, connect the thermostat NET1 wiring to the NET1 port ofthe DFM 4xx/eZNS/DNS.

2. Confirm communication between each thermostat NET1 and the DFM-4xx/eZNS/DNS.

The available LINKnet address range is 1-4 with a maximum of four LINKnetdevices or two DFM-4xx devices. The related objects are LCDx001 and LNKx001where x is the network sensor device address and is a number between 1 and 4.

The following figure shows a wireless thermostat with four LINKnet devices andthe LCD and LNK object instances.

Device InfoThe Device Info section of the configuration page provides a way to disable orenable the Micro-USB port. The port provides service access but you may want todisable it when it is not in use.

The enable/disable function for the USB port also controls the internal webserver. The exception is that the internal web server is always enabled when theAccess Point (AP) interface is enabled.


The Keypad Password is a 4-digit PIN that controls access to the on-screenconfiguration menu. This password is stored in AV531. To be valid, the passwordmay only consist of 1s and 0s. The default value is 1011.

If you want to completely disable access to the on-screen configurationmenu, you could set a password that contains characters other than 0 or1.

enteliWEBUsing the enteliWEB Objects page, you can configure the IPS2 and IPS1 objects,which contain the following settings:

l IPS2 – Host AP mode initial settingsl IPS1 – Client Station mode router settings

IPS2 Configuration SettingsHost Access Point (AP) mode provides a temporary connection to do initial setupand troubleshooting. Host Access Point (AP) mode is off when the eZNT-Wi is innormal operation. Station mode is used for normal operation. AP modeautomatically turns off after 30 minutes with no AP activity.

With the configuration webpage, you can connect to an eZNT-Wi directlyvia AP mode. However, enteliWEB does not work in AP mode as thismode does not support BACnet over IP.




AP Mode can be enabled or disabled for a specific wireless eZNT-Wi thermostat. IfAP mode is left on with no activity for 30 minutes, it turns off automatically. Thisauto off is included for security reasons.

Enable/Disable AP Mode

A user can turn AP mode On/Off from the Display Configuration Menu.

When AP Host mode is turned on, BACnet over UDP/IP performance is extremelydegraded in Client Station mode. The communication speed in dual mode (AP Hostand Station mode together) might then be less than 10% of that in Station modeonly.

To enable or disable AP Mode in IPS2, in the AP settings section, select or clearthe Enable checkbox.

AP SSID (Network Router) Name and Password

The SSID field displays the eZNT-Wi AP SSID, which is factory set and cannot bechanged. The MAC address provides a unique identifier for each Wi-Fi thermostat.


The wave icon in the SSID field indicates signal strength for Wi-Ficommunications. An increasing number of dark blades indicates greater signalstrength.

The SSID is composed of 'eZNT' and the last four digits of the AP mode MACaddress. For example, the router network name (SSID) might be: eZNT-447E

The last 4 digits of the SSID (e.g. 447E or A3A9) briefly display on the thermostatduring power up. The full SSID is also displayed on the eZNT-Wi configurationwebpage and enteliWEB device object page.

The default password is DeltaControls.

To change the password for the SSID:

1. In the AP Settings section, in the Password field, type a new password.2. In the Command field, select Commit Settings.3. Click Save.

This password can also be changed in the eZNT-Wi configuration webpage.

IPS1 Configuration SettingsIn Client Station mode, both the configuration webpage and enteliWEB work. In APmode, only the configuration webpage works, since enteliWEB requires BACnetover IP, which AP mode does not support.

The IPS1 object configuration page shows the IP address of an eZNT-Wi device inthe network. You need to know the IP address of the eZNT-Wi device to access thispage. You can find this out from the connected device table of your router.

The following figure shows the IPS1 (Client Station mode) object page inenteliWEB.




The following settings are available:l SSID – Displays a list of available routers within range. The field also displaysthe Wi-Fi signal strength.

l Password – Specifies the password for the selected router.l Use DHCP – Enables DHCP. If you want to enter the IP settings manually,clear the checkbox.

To change the SSID:

1. In the SSID field, click the arrow to show the list of available router SSIDs.2. Select a router SSID.3. In the Command field, select Commit.4. Click Save. A green checkmark indicates a connection, while a red

exclamation mark indicates a failed connection attempt.

For a list of IPS properties available for GCL+ programming, see IPS Wi-FiProperties Available in GCL Using enteliWEB.

What is the SSID? When you power up aneZNT-Wi, it brieflydisplays the SSID,firmware version, andfirmware build number.


Troubleshooting Wi-Fi Issues



Signal Strength Verify signal strengthfrom router and theeZNT-Wi.

See the AV94 (WiFi_RSSI)entry in the ObjectInstances Numbers tablein the Database Objectssection. AV94 contains theWi-Fi signal strengthvalue from the IP1.RSSIproperty.

For the eZNT-Wi, the RSSIsignal strength in dBshows on the defaultdisplay to helptroubleshoot connectionsduring Wi-Fi setup. Whenthe thermostat isconnected to a wirelessnetwork, the temperaturereading in degC shows online2 and the RSSI valueshows on line3 of thedisplay. If the thermostatis not connected to awireless network, line3shows a signal strengthvalue of 0.

An RSSI value of -70dB orless indicates a weaksignal with higherchances of wirelesscommunication problemssuch as offline devices.Database save/load andfirmware flashingoperations also may fail.Communications are alsoaffected by the wirelessnoise in the environmentand the number of deviceson a channel and thechannel overlap.

The router (rOU) on-screen configurationmenu item indicates theWi-Fi signal strength(AV94) by displaying 0 (nosignal) to 5 (very strong)curved bars. It isrecommended to have asignal strength of at least-70 dB (2 bars).

In addition, when a statwith Wi-Fi is powered upwithout a database, theWi-Fi signal strengthshows on line3 of thedisplay.



Recover from incorrect configuration. Verify SSID and passwordfor router.

Sometimes a Run/Clearprocedure must be doneto return the database tothe factory default andalso to remove anyretained network settingsinformation.

See Appendix A: DatabaseOperations for the stepsrequired to put anthermostat back into thedefault factory state.

Unable to access service port Verify that the USB port isenabled in either the on-screen configurationmenu or the configurationwebpage.

Shut downenteliWEB/ORCAviewBACnet front end andrestart. If a reset occurs,it will not automaticallyreconnect.





How return to factory default settings

Run/Clear jumper must be put back to Run for thethermostat to function correctly.

Open the thermostat, putthe Run/Clear jumper inthe Clear position. Put thefrontplate back inposition, then applypower. Remove power,open the thermostat, andreturn the jumper to theRun position.

See Appendix A: DatabaseOperations for the stepsrequired to put anthermostat back into thedefault factory state.

Clear the database but keep the network settings Save the database andthen use the ClearDatabase command fromenteliWEB. The objects inthe database are put todefault. However thenetwork settings areretained and are NOTcleared.

Working with the On-Screen ConfigurationMenuThe enteliZONE network sensor and thermostat products offer means to navigatemenus and display values using the on-screen configuration menu. When youenter the password, you can navigate and modify configuration settings.

When a new eZNT-Wi or eZNTW/eZNTW-Wi is powered ON, it is in the defaultmanufactured state and briefly displays the firmware version, firmware buildnumber and the SSID on the screen. For example, on powerup the followingvalues might display: 340 (firmware version), 425 (firmware build number, first 3of 6 digits) and 238A. The SSID 238A consists of the last four hex digits of the APMode MAC address.

For an eZNT-Wi or eZNTW-Wi with 3.x firmware (Build 428051+), the display nowshow RSSI signal strength information to help troubleshoot Wi-Fi connectionsduring setup. When a device is connected to an wireless network, the defaultdisplay shows the current temperature reading in degC on line2 and theRSSI signal strength shows on the bottom line (line3). To display temperature indegF units, set the Object Sensor Type field in AI1. The line3 display area can showfour characters and does not include a dB unit after the RSSI value. If the device isnot connected to a Wi-Fi network, then a value of 0 is shown in the line3 area. If aGCL program is writing to the LCD0 line2 or line3 display property, the defaultscreen is cleared. For more information, see the AV94 (WiFi_RSSI) entry in theObject Instances Numbers table in the Database Objects section.

Many of the settings can also be modified through the on-screen menu availableon each unit. Often, the quickest method to configure an enteliZONE thermostat isto use the NFC NetBuilder and/or the Stat Configurator apps. The NetBuilder appfocuses on the settings to get a thermostat addressed and running on the networkwhile the StatConfigurator focuses on thermostat settings such as button layout,touch sensitivity and display backlight color. For more details, see the Workflow:Wi-Fi Setup section.

Configuration Menu AccessAccess to the configuration menu is protected by an access code or PIN. You mustenter the valid PIN before access is granted.

To access the configuration menu:


Working with the On-Screen Configuration Menu


1. Press and hold touch area 8.2. While holding touch area 8, press and hold touch area 4. Hold them both

down for at least 5 seconds until PIN displays on the screen

3. When the PIN number text displays, enter the valid PIN or access code. ThePIN is a preconfigured 4-digit code that you must enter to gain access to theconfiguration menu. Button 1 maps to value 0 and button 4 maps to value 1.Press the proper button sequence to match the password.

The default PIN is 1011.

4. When you enter the valid 4-digit code, the configuration menu then displayson the screen. CFg is displayed on the screen to indicate Configuration mode.

If the entered code is invalid, the process aborts and the unit returns tonormal display mode. If you do not press a button within a 2-minute period,the unit returns to normal display mode. In both these cases, the unit keepsthe same PIN used when the last connection was made to the controller.

The PIN access code is stored in AV531. The PIN stored in the AV objectcan be changed when the device is connected to the network, but notthrough the keypad. The keypad can only enter either 1 or 0 for the PINand this limits the range of available values for AV531. In some situations,you might deliberately set a PIN that cannot be entered from the touchscreen.

Button and Navigation FunctionsWhen the device is in configuration mode, the following button functions areavailable:


Use the Next (touch area 4) and Previous (touch area 1) buttons to navigatethrough the menu options. Navigate to the item that you wish to display or changeand then use the Down (touch area 5) and Up (touch area 8) buttons to make anynecessary changes. When you are finished, navigate to the End item, then selectYES to save the changes and exit the configuration menu.

AV94 AV94 contains the Wi-Fi signal strength value(dB) from the IPS1.RSSI property. Availableonly in eZNT-Wi and eZNTW-Wi devicesrunning firmware 3.1.3 and later.

AV94 exists in the default database andcannot be deleted. With upgraded databases,you can create AV94 to expose the Wi-Fisignal.

The RSSI Wi-Fi signal strength shows on thedisplay by default.

l When the thermostat is connected to awireless network, the temperaturereading in degC shows on line2 and theRSSI shows on line3 of the display.

l If the thermostat is not connected to awireless network, line3 shows a signalstrength value of 0. If any GCL programwrites to the LCD0 line2 or line3property, then the default screen iscleared.

An RSSI value of -70dB or less indicates aweak signal with higher chances of Wi-Ficommunication problems such as offlinedevices. Database save/load and firmwareflashing operations may also fail. In the on-screen menu, the rOU router menu itemdisplays the Wi-Fi signal strength bydisplaying 5 (very strong) to 0 (very weak)bars on the screen.

R/W

enteliZONE products use AV/BV/MVs up to 999 for configuration variablesand up to 9999 for enteliZONE controllers that support LINKnet. With theeZNT-Wi/eZNTW, it is recommended practice to start at 1000 for usercreated variables to avoid future firmware that may include additionalconfiguration variables in the 1-999 range. LINKnet variables are withinthe range of 1000 to 4000.

Non-Volatile VariablesMany of the AV objects in the previous variables table are stored locally in non-volatile NFC memory on the thermostat itself.

There are multiple ways that some of these properties can be changed, but thenon-volatile NFC location is the ‘master’ location. This allows changes to be madeeven when the thermostat is powered off; however this approach can have someunexpected consequences.

These local values can be modified in several ways:l Use an Android NFC App such as Stat Configurator for eZNx specific settingsor NetBuilder for network and address settings. The thermostat does notneed to be powered on and can even be inside its shipping box. It takes about10 seconds to configure each controller and so this approach can savesignificant time in many cases.

l Configure some properties through the on-screen enteliZONE ConfigurationMenu such as Motion Sensitivity or USB enable/disable.

l Change the AV objects in the thermostat controller database.

In normal powered operation, the database AV values match the local valuesstored on the enteliZONE thermostat.

l When changes are made from the database side, they are written to the localthermostat non-volatile memory.




l When changes are made from the NFC/Configuration Menu, they are writtendown to the controller database AVs. If NFC is used while the thermostat isnot powered up, the next time that it is powered up, the changed values arewritten to the database variables. If GCL is rewriting to that object, attemptedchanges made from the NFC/Config Menu may not actually occur.

When you load a database into a thermostat, the values in the database and thevalues in the non-volatile memory may differ. On power-up, the thermostatattempts to write back its existing local value to the AVs. If values such as On/Offbrightness or USB Port access need to be set in database, these configuration AVsshould be initiated and modified through GCL.

LCD Object and Display IconsThe LCD object is a Delta Controls proprietary object that configures the displayand keypad.

Using the LCD object properties, you can set up the LCD screen display icons.l To access the LCD object properties, open the active LCD object page and inthe lower left corner of the object page, click the Toggle Property List button.This button is only visible when you mouse over it.

l If you are using a configurable enteliZONE parent controller, you canconfigure the display on the LINKnet I/O tab on the enteliZONE configurationpage. See the application guide of the enteliZONE controller for more details.

Some icons on the display are not directly controlled. The 14 Arrow Icons functionautomatically based on touches to the appropriate corresponding button / buttonconfiguration setting. The arrows can be configured as either momentary or tostay on (sticky) until programmed off from the Configuration Menu Options.

Programming eZNx Buttons and ScreenThis section covers layout and configuration of buttons, and the GCL-programmedinteractions with buttons and the slider.

GCL is used to program the thermostat user experience. The display and buttoninteractions are configured primarily by reading button presses from theLCD0.Key_Press property and writing to various display properties of the LCDobject. Reading and writing to database objects can adjust additional displaycharacteristics such as color or brightness and also provides a way to simplifyslider interaction.

For example, you might want to control a fan speed by having a user press the fanicon. You would program the thermostat to recognize a fan button press, displaythe current fan speed and then allow the – or + slider icons below the display toadjust a value.

Button MappingThis topic covers button layout and configuration plus using GCL with buttons andthe slider.

Button LayoutThe standard eZNx device has up to four buttons above the LCD, up to four buttonsbelow the LCD, and a horizontal slider below that.

These buttons correlate with numbered touch areas shown in the followingillustration.

The touch areas on the device can be combined to form different buttonconfigurations. For example:


Programming eZNx Buttons and Screen


l You can create two buttons on the top row by combining touch areas 1 and 2and touch areas 3 and 4. Similarly, you can create two button on the bottomrow by combining touch areas 5 and 6 and touch areas 7 and 8.

l You can create three buttons on the top row by combining touch areas 2 and3 and three buttons on the bottom row by combining touch areas 6 and 7.

The following table summarizes the button options available for each row.

Buttons Per Row Top RowTouch Areas 1-4

Bottom RowTouch Areas 5-8

1 Button 1+2+3+4 5+6+7+8

2 Button 1+2 and 3+4 5+6 and 7+8

3 Button 1 and 2+3 and 4 5 and 6+7 and 8

4 Button 1, 2, 3, 4 5, 6, 7, 8

The button layout is factory set to match the overlay; however it can be modifiedusing the onscreen Configuration Menu if a different combination is needed fortesting.

Button and Slider ConfigurationThe button layout configuration is in the Configuration menu. Mappings are madefor each button to map the physical touch area to a logical button.

Each row of touch areas 1-4 and 5-8 can be configured internally as 1, 2, 3 or 4buttons. This allows for larger areas to be treated as a single button to match thebutton overlay used. See the Configuration Menu section for more details.

The slider is at the bottom of the display is used to increase and decrease valuesusing a sliding action or +/- operation.


(Firmware versions before R3.1.3) The slider active zone is always presentregardless of the button overlay.

l The slider is typically used to adjust light levels or temperature setpoints inconjunction with a sticky button. The idea is to push a button such asTemp/Fan/Light/Blind, which through a sticky button arrow indicates that aspecific mode is enabled. The slider is then used to set that mode’s setpoint.

(Firmware R3.1.3 or later) The slider includes a beep feedback sound for a pressaction. When you touch the slider, the beep provides confirmation of a sliderpress. The slider beep function is disabled for standard mylar overlays that do nothave a slider area.

The standard / stocked mylar overlays that do not use the slider include: 00, 22,28, 34, 46 and 47. For custom mylar overlays, we cannot predict if the overlay usesthe slider.

Button GCL ControlWhen programming the button behavior through GCL, the buttons are read withthe LCD0.Key_Press property. Each button is internally represented in increasingorder from Left to Right and Top to Bottom. For example with two buttons on thetop and four buttons on the bottom, the top two buttons are read as keypress 1and 2 and the Bottom row of buttons are read as keypress 3 through 6.

The available KeyPress values supports up to eight buttons (i.e. value from 1-8 forsingle button presses and from 102-807 for two button presses). For examplepressing button 3+4 would give a KeyPress value of 304. The order of pressing isimportant. Pressing 4+3 would give a KeyPress value of 403.

Slider GCL ControlThere are two methods of reading values for the slider:

Simple Control. The thermostat is sent the range and increment in advance whichsimplifies reading the setpoint and allows GCL to act on the value as it is changed.The slider changes the setpoint between the given ranges. The + and – on the endsof the slider increase or decrease the setpoint by the increment value and allowfor auto repeat when pressed and held.

Simple control is active when AV518 is set to value 1 (for the LCD lower displayline) or value 2 (for the LCD main display line).




Advanced Control. The thermostat can read the absolute start and stop position ofthe slider through the GCL KeyPress property. GCL then acts on the informationand performs some changes such as adjusting a setpoint. The limitation with thisapproach is that the value is not read until you finish sliding and remove yourfinger, and requires additional programming. The advantage is to allow furtherflexibility on how the slider is used.

Advanced control is active when AV518 is set to value 0.

Simple Control (AV518=1) – LCD Lower Display Line (Line 3)When simple control is active (AV518 = 1), the lower display line is set by thesevariables:

l AV519 – Minimum Valuel AV520 – Maximum Valuel AV521 – Slider incrementl AV522 – Current display value being changed by the sliderl AV523 – Units to display on the lower line

The logic on how one would use this is as follows:

1. Detect Button Press [e.g. light button pressed].2. Set Min=30, Max=100, increment=10, Lower Units= 4 (%).3. Set slider value (AV522) to the current lighting setpoint.

4. Set AV518=1 for simple control.

Now the user can adjust the lighting setpoint from 30-100 by sliding orpressing on either end of the slider for incremental 10% increase/decrease.

5. As the slider value is changed, use GCL to set the new lighting setpoint = newslider value.

6. After some timeout (KeyPress=0 for x seconds), disable simple control bysetting back to advanced control (by setting AV518=0).

The lower display line now will revert back to using the LCD0 objectproperties Line3Units and Line3 properties.

Notes:l When AV518 = 1, LCD0 object properties Line3Units and Line3 properties areignored. These display fields are controlled by the thermostat and objectsAV519-523.


l The slider can recognize 10 different regions, which means that if yourincrement*10 is less than your range, it will take multiple finger slides tomove a setpoint between minimum and maximum values.

l Pressing and holding the ends allows repeat increment/decrement.

Simple Control (AV518=2) – LCD Main Display Line (Line 2)Simple Control (AV518=2) functions similar to Simple Control (AV518=1) but theslider setpoint value and units are displayed on the main LCD line (Line2) ratherthan the lower LCD line (Line3).

While AV518=2, the LCD0 properties Line2 and Line2Units are ignored, and themain LCD display line is controlled from the slider using the values in objectsAV519-523.

Advanced Control (AV518=0)When in advanced control, the slider is read in a similar manner to the buttons butthrough the KeyPress property. The value provided to GCL gives an indication ofthe initial finger position and the final finger position. These values are not sent tothe application controller until the finger is released. Using advanced controlallows for further flexibility when it comes to interpreting how the slider works.

The slider changes are represented in a higher range of values in the KeyPressproperty, 10000-19999. The first digit represents the slider (1), the next two digitsrepresent the start position (00-99) and the last two digits represent the endposition (00-99). For example, pressing and dragging from 30% to 70% gives aKeyPress value of 13070. Pressing and dragging from 70% to 30% gives aKeyPress value of 17030.

GCL Code Example for Simple Slider Control of a SetpointThe following code segment shows how to adjust a setpoint using the slider foreZNT, eZNT-Wi and eZNTW products.

Backlight OperationThe backlighting feature allows the adjustment of the color and intensity of thebacklight. The backlight on the thermostat is controlled by:

l LCD0.Backlight – Turns on or off the backlightl AV527 – Backlight Off intensity (0-100%)l AV528 – Backlight On intensity (0-100%)l AV529 – Backlight color using 1-13 states, 0=custom


l AV526, AV525, AV524 – When AV529=0, the backlight color uses a customcolor that is determined by setting a RGB value. The RGB value is set usingthese objects: AV526 = R, AV525 = G, AV524 = B. Each object value range is 0-255.

Dynamic control of the backlight state (on/off), intensity, and color can be donethrough GCL programming.

An alternate method of controlling the backlight intensity is by using AV530, theAutomatic Backlight timer.

l When this timer value is > 0, a key press will turn on the display (AV528determines the Backlight On intensity level). When no buttons are pressedfor the timer value, the display will turn off (AV527 determines the BacklightOff intensity level).

l When this timer value = 0, the timer is disabled. Instead, LCD0.Backlight isused to set backlight according to AV528 On Brightness or AV527 OffBrightness.

IPS Wi-Fi Properties Available in GCL Using enteliWEBFor the eZNT-Wi, the IPS1 object is associated with the Client Station Modeinterface. IPS2 is associated with the AP Host Mode. The IPS properties in theinterface that are shown with a green color are available in GCL using enteliWEB.

Manage Database TasksThis section discusses the basic firmware and database management tasksperformed on the enteliZONE thermostat.

When ORCAview is mentioned, this guide recommends ORCAview 3.40 build 3946(3.40 Release 4) or later.

When enteliWEB is mentioned, this guide recommends enteliWEB 4.14 or later, orotherwise specified.

Upgrading FirmwareUse the ORCAview System Loader or Flash Loader utilities to load the version 3firmware. System Loader can upgrade multiple devices at a time.

Saving and Loading DatabasesThe eZNT databases can be saved and loaded using enteliWEB or ORCAviewSystem Loader or Flash Loader utilities.

If you use Flash Loader, you can log in over Ethernet but you must have a devicesuch as a system controller to route over UDP/IP to the eZNT-Wi.

System Loader can log into an enteliZONE thermostat directly over UDP/IP.

When you upgrade firmware using System Loader or Flash Loader, make surethat AP mode is off as BACnet data transfer is extremely slow if AP mode is on. Itis recommended to avoid any BACnet operations while AP mode is on.

Using enteliWEB to Manage DatabasesenteliWEB is a flexible tool that provides several options to manage devicedatabases. Select the best option for your needs.

l To create backups or load backups into devices, go to > Manage DeviceDatabases page. These backup tasks can also be scheduled in enteliWEB.

l To save, load or clear controller databases, select the device on the leftnavigation pane to open the object list page, and use the Device Actionsoptions to complete your database task.


Manage Database Tasks


Clearing DatabasesThis section explains how to clear the database in an enteliZONE thermostat andhow to return a thermostat to the default factory state.

Clear Database Using ORCAview/enteliWEB1. Ensure that the database is backed up as Clear deletes the current database

and replace it with the default database.2. If you use the Clear Database command from ORCAview or enteliWEB, the

objects in the database are put to default objects. However the networksettings are retained and are NOT cleared.

Return a Thermostat to Default Factory StateThe device has a Run/Clear jumper that provides a way to restore all objects tofactory default. Any network configuration information is also cleared. The DNAsetting is also reset back to default ON.

For the eZNT-Wi, dual mode is the default behavior on a new device or after areset to the factory default database using the Run/Clear jumper.

To clear the database using the Run/Clear jumper:

Ensure that the database is backed up before you begin this procedure.

1. Remove power from the device.

2. Remove the frontplate from the backplate.

3. Put the Run/Clear jumper into the Clear position.

4. Put the frontplate back on the backplate.

5. Apply power. You need to apply power to clear the database to factorydefault.

6. Wait for the display to show Clr and flash with a red color.

7. Remove power from the device when ‘done’ displays on the screen.

8. Remove the frontplate and put the Run/Clear jumper into the Run position.

9. Replace the frontplate.

10. Power the unit on. The device operates normally and shows the startupinformation for the thermostat when it is powered up.

If the Run/Clear jumper is left in the Clear position and power is applied, the unitwill NOT start up. The display indicates this condition by showing Clr and flashing

Appendix A: eZNx CO2 Sensor Calibration forenteliZONEThis section provides CO2 calibration procedures for hardware revision 3.3 andhigher eZNx products.

Calibration can correct drift over time as well as correct offsets that may haveoccurred from mechanical stress the sensor has endured, either accidentally orduring shipping.

This topic applies to the eZNT CO2 model with a hardware revision later than 3.3running firmware V5.0 or later.

Two methods of calibration are discussed in this topic:l Manual calibration (preferred method)l Auto calibration

The calibration is not a constant offset across the range; the CO2 AICalibration object property should NOT be used to calibrate the sensor.

Calibration Using AV ObjectsThe CO2 sensor uses the AV511 (Calibration mode) and AV512 (CO2 CalibrationValue) object instances for calibration.

About Calibration Mode

The AV511 object is used to set the current calibration mode.l "0" value enables auto calibration mode or background calibration by theeZNx device itself

l "1" value enables manual calibration mode if you are using gas flow orhandheld meter calibration

The AV511 object will also display status if the object is commanded to Auto (notout of service).

l "-1" value indicates a problem, such as a missing CO2 sensor, or a failure tocommunicate with the CO2 module

Attempting to set the AV511 object to values other than "0" or "1" will cause theobject to revert back to its previous value after 10 seconds.


Appendix A: eZNx CO2 Sensor Calibration for enteliZONE

About CO2 Calibration Value

The AV512 object is only used when AV511 object is set a value of "1" to indicatemanual calibration mode.

Manual Calibration (Preferred Method)Manual calibration uses a single point reference value to apply an internalcompensation formula across the entire CO2 module range. The reference value isa known gas concentration or a calibrated CO2 reference sensor reading. Thereference value is written as a raw value to the CO2 module. Note that manualcalibration does not use the AI object calibration property as an offset.

This single-point manual calibration method is available for buildings that haveirregular occupied periods or do not come down to approximately 400 ppmambient CO2 overnight. Manual calibration is the preferred calibration method inthese cases, as it does not depend on building operating conditions.

The following procedure describes using a CO2 gas reference. However, anaccurate calibrated reference could also be used to determine the calibratedvalue you should enter.

Before You Beginl Decide how you are going to apply the manual calibration. Choose one ofthese methods:

l Using the on-screen config menu on the enteliZONE devicel Using database objects in enteliWEB or ORCAview

l The eZNx device should be mounted and operating in normal stable operatingconditions and powered up for at least two minutes before applying manualcalibration.

l Decide how you are going to obtain a CO2 reference concentration level.l If a calibration gas is used, it should be within the 400-2000 ppm range.A calibration gas has a nominal value (e.g. 1000 ppm) but the actualcertified value (e.g. 940 ppm) used in the calibration procedure differs.

l If a calibrated reference sensor is used, it should be as close to theeZNx device as possible. Avoid breathing near the sensors whilemeasuring.




Introduce a Calibration CO2 Gas to the eZNx Device

The CO2 sensor backplate contains a port on the bottom that supports inserting atube which directs a low flow (0.3 – 0.5 l/min) of known CO2 concentration gasacross the CO2 module.

1. Introduce the known CO2 concentration gas into the eZNx device through theport.

a. Obtain CO2 in a known concentration (e.g., a nominal 1000 ppm) withregulator allowing you to vary the flow of CO2 gas.

Note that when a calibration gas is ordered at a nominal value(e.g., 1000 ppm) the actual 'certified value' will differ (e.g., 940ppm). This certified value is what is used in the calibrationprocedure and is typically listed on the CO2 bottle label orpaperwork that came with the CO2 purchase.

b. Obtain a 5 mm (3/16”) outside diameter plastic hose of at least 50 mm(2”) length that can be used in the calibration port.

c. Connect this plastic hose to the CO2 cylinder via additional hose andreducers as necessary to achieve a length that will reach between themounted eZNx device and the CO2 cylinder location.


d. Insert the 5 mm OD plastic end piece into the port on the left bottomside of the backplate. If necessary, tape can be wrapped around the 5mm hose to ensure a snug fit. The hose should be gently inserted untilresistance is felt.

e. When needed, use the gas regulator to send a low flow rate of around0.3 liters per second into the channel that connects to the plasticenclosure around the CO2 sensor. Excessive flow can introducetemperature instability, as cooling from expansion of the gas canadversely affect the reading.

2. While the gas is still flowing, apply the manual calibration using one of thesuggested methods described below.

Manual Single Point Calibration Using the On-Screen Menu1. On the device, log into the on-screen Config menu. To find out how to access

this menu, go to Configuration Using the On-Screen Menu section.2. From the On-Screen menu, touch the button 4 area to move through the

options until you reach CLb. Set the calibration mode to manual calibrationmode by selecting the Yes option. You leave this setting in the manualcalibration mode when the calibration is done.

3. Using button 4, move to the next CLb item. This menu item shows the currentreal-time value. Monitor this value, and, when stable (after about 2 minutes,use the Up (button 8) and Down (button 4) to set the value to the knowncertified concentration of the standard CO2 gas. For example, if using a CO2gas with certified calibration value of 940 ppm, you would set 940 here.

4. To save the changes, press button areas 6+7 together for a few seconds andthen release. The screen flashes three times to indicate that the new valuewas saved.




An entry is written to the AV512 C02CalibrationValue description field(AV512.description) and it includes the manual calibration value and atimestamp, overwriting any previous description.

5. When all changes are done, navigate to the End item in the menu and selectYes to save the changes. An internal algorithm in the CO2 sensor uses thesingle point manual calibration value to apply compensation across the entirerange in a non-linear manner.

Manual Single Point Calibration Using enteliWEB or ORCAviewConnect to the eZNx device using enteliWEB or ORCAview, and then to do amanual calibration.

1. Set up a 5-second polling trend log to monitor the AI4 (CO2 Sensor) whichinitially shows the current CO2 value output from the sensor.

2. On startup, the eZNTx reports the current status of the CO2 sensor in theAV511 object. A value of -1 indicates problems with the operation of the CO2sensor. Ensure the CO2 sensor is working normally before proceeding.

3. If necessary, enable Manual Calibration mode by setting the AV511(CO2ManualCalibration) value to 1.

l In enteliWEB, select the AV object on the object list, and from theCommand menu select Manual value. Enter the value and press Save.Put the object back into Auto.

4. Command the AV511 object to Auto (in-service) to allow reporting errorcondition (if there is an error, the AV511 object value is -1).


5. When a stable CO2 reading is reached, as viewed from the monitored trendlog (~2 minutes), manually set AV512 to the known certified concentrationvalue of the CO2 gas (via either known CO2 gas concentration or calibratedhandheld sensor). Acceptable values are 400-2000 ppm.

l If the AV512 value is out of range, an AV511 value of -1 is returned.l If the AV512 value is valid and the manual calibration mode is enabled(AV511 is equal to 1), then the calibration value entered in AV512 issaved and a 20 second countdown timer starts.

6. Within 20 seconds of setting the CO2 value in the previous step, manually setthe AV512 object value to 0.

7. Command the AV512 object to Auto (in-service) to report the status of thecalibration.

l If a failed calibration is reported, the AV512 object value is -1.

Possible reasons why a calibration is not applied:o AV511 object was not set to 1 (manual calibration mode)o the calibration range is outside of 400-2000ppmo the calibration value was received outside of the 20-second window

l If a calibration was successful, the AV512 object value is 0. This meansthe calibration was accepted and applied. An entry is written to theAV512 C02CalibrationValue description field (AV512.description) and itincludes the manual calibration value and a timestamp. The previousinformation in the description field is overwritten.

An internal algorithm in the CO2 sensor uses the single point manualcalibration value to apply compensation across the entire range in anon-linear manner.

The CO2 value for object AI54 will adjust to the calibrated value on thenext update.

Auto CalibrationAuto calibration looks for periodic minimum CO2 readings for buildings that comedown to the outdoor ambient level during nightly unoccupied periods and calibratethese minimum values as 400 ppm. This means that the building is unoccupied forsome period each day and that the site elevation allows the CO2 level to drop to400 ppm daily. The CO2 level decreases by about 3% for every 1000 feet (300 m)




increase in elevation above sea level. For example, the ambient CO2 would bearound 370 ppm at 2000 feet (610 m).

The manual calibration mode is the default and is generally the preferredmode as most buildings won't completely come down to the ambient leveldaily.

Before You BeginIn auto calibration mode, the sensor assumes the building comes down to 400ppm ambient CO2 daily. The internal sensor calibration algorithm requires at least7 days (periods at least 18 hours apart) of minimum values within 50 ppm of eachother before calibration is applied. This internal calibration is automatic andcontinual, using the last seven minimum values stored to calibrate the sensor.The eZNx device must be powered continuously during this period. If power is lost,all minimum values are lost. After a power loss, the unit operates with standardsignal compensation until another set of seven acceptable minimum values areacquired.

Auto calibration does not require a CO2 calibration gas of a known certifiedconcentration.

Auto Calibration Using the On-Screen Menu1. Log into the on-screen Config menu. To find out how to access this menu, go

to Configuration Using the On-Screen Menu section.2. From the On-Screen menu, touch the button 4 area (Next) to move through

the options until you reach CLb. Set the calibration mode to auto calibrationmode by selecting the AUTO option.

3. Move down to the next CLb item. This menu item shows the current real-timevalue and updates every 5 seconds. In AUTO mode, the SET buttons aredisabled and you cannot change the displayed value.

4. When all changes are done, navigate to the End item in the menu and selectYes to save the changes.

Auto Calibration Using enteliWEB or ORCAview1. On startup, the eZNT device reports the current status of the CO2 sensor in

the AV511 object. A value of -1 indicates problems with the operation of theCO2 sensor. Ensure the CO2 sensor is working normally before proceeding.


2. Manually set the value of the AV511 object to 0 to enable auto calibrationmode.

l In enteliWEB, select the AV object from the object list and then selectManual value from the Command menu. Enter the value "0" and thenpress Save. Put the object back into Auto.

3. Command the AV511 object to Auto (in-service) to allow reporting of anyerror condition (if there is an error, the AV511 object value is -1).


Appendix B: eZNx USB Service Port forenteliZONEYou can use your laptop or desktop to connect to the USB service port on theenteliZONE network sensor or thermostat. The service port allows you to view theobjects on the enteliZONE device, or connect to the building's BACnet networkwith a BACnet MS/TP connection in enteliWEB (version 4.8 or later) or ORCAview.

This topic describes how to establish a connection between the eZNx USB serviceport and your laptop or PC.

Before You BeginEnsure the USB service port is enabled. By default, the service port is enabled.Check the status of the service port using one of the following methods:

l Create object AV506, and make sure its value is set to 1.l Using the on-screen configuration menu (USb).l Using the web server configuration page.

You will need a Micro-USB-to-USB data cable.

The eZNT devices need to be powered.

Install the Virtual Serial Port DriverIf you have a working driver from a previous eZNS driver installation, then noaction is needed. The eZNx driver files have the exact same function as theprevious eZNS driver files.

The eZNx device uses the virtual COM port that is created when the device isconnected to a laptop/PC (via Micro-USB to USB) with the Delta USB driver fileinstalled. The eZNx devices do not need a CON-768BT adapter.


Appendix B: eZNx USB Service Port for enteliZONE

Some comments about the eZNx and the eZNS Delta driver folders:l It is not necessary to replace the eZNS driver on Windows 7 or 10 with theeZNx driver. With Windows 10, you can replace the default Microsoft driverwith the Delta eZNx but it is not necessary.

l If you previously installed the eZNS driver on Windows 10 or Windows 7, thisdriver still works fine and there is no need to change to this eZNx version.

l Windows 10 has a generic Microsoft driver that is installed when you let thesystem search automatically for a driver. This generic Microsoft driver worksfine. You can also use the Browse for Driver option and select the Delta eZNxdriver folder. You need to unzip the eZNx folder that you can get from theeZNx device product page on the George support site.

l Unlike Windows 10, Windows 7 does not have a generic driver and the eZNxdriver (or old eZNS) must be installed.

To install the Delta eZNx driver:

1. Download the USB virtual COM port driver from the enteliZONE deviceproduct page on the George Support website. The zipped folder (usb_inf.zip)contains the eznx_ser.cat and eZNx_ser.inf driver files.

Unzip the folder.

2. Plug the Micro-USB connector into the eZNx device and the USB connectorinto your PC or laptop. A dialog opens on your computer asking for a driverfile.

3. Choose the Browse my computer for driver software option to install fromthe location of the downloaded driver files.




If the driver does not install automatically, open the Device Manager inWindows and install the driver manually.

a. (Windows 10) In the Device Manager, under Ports (COM & LPT), find theenteliZONE device.

(Windows 7) In the Device Manager, under Other Devices, find theenteliZONE device.

If there are multiple generic ‘USB Serial Devices’ under COM Ports,have the Device Manager open BEFORE connecting the device. It willthen automatically refresh and you can see which device the enteliZONEdevice comes in as.

b. Right-click on the virtual COM port and choose Upgrade driver. SelectBrowse my computer for driver software and locate the directory wherethe unzipped driver files are located.


c. If a Windows Security dialog appears, click Install.

4. Once installed, a virtual serial port is created. A success message appearswhen the driver software installation is complete.

5. To get details about the driver, select the port in the Device Manager andclick Properties.




Configure the ConnectionWhile the enteliZONE device is connected to your laptop or computer, create aconnection between the device and enteliWEB or ORCAview.

When a connection is successfully established, you can view the objects on theenteliZONE device as well as other devices in the network.

Using enteliWEB to Create and Configure the Connection1. You should know the virtual COM port number before you create the

connection. The number should be displayed in the Device Manager when youinstalled the virtual COM port driver.

2. In enteliWEB, click > Sites.

3. On the same row as the site name on the far right side, click AddConnection. The Add Connection dialog opens.

4. From the Type list, select MS/TP.

5. For enteliWEB 4.14 or later, select the virtual COM port that you installed.For example, COM7 eZNx Virtual Com Port (COM7). If the eZNx COM Port isnot listed, refresh the page or log out and log back into enteliWEB. The eZNxCOM port should display in the drop-down list.

For enteliWEB 4.8 to 4.13, the virtual port does not show in the drop-downlist. You must manually type the virtual COM port number as COMx where x isthe port number.

6. Enter the MAC Address for the connection. The default value of 127 is usuallyokay. It is suggested to stay with the range of 100-127 to avoid conflicts withany existing networks that are in the 0-99 range.


7. Click Add.A check mark status indicator is displayed when enteliWEB is connected tothe network, otherwise is displayed to indicate that enteliWEB was unableto create the connection.

8. Refresh the enteliWEB page.

Using ORCAview to Create and Configure the ConnectionThe ORCAview OWS provides access to the objects in an eZNx device and also theother devices in the network using a connection to the micro-USB Service Port.

1. You should know the virtual COM port number before you create theconnection. The number should be displayed in the Device Manager when youinstalled the virtual COM port driver.

2. Create a connection between the enteliZONE device and and ORCAview usingthe virtual COM port.

a. On the ORCAview OWS Logon dialog, click Advanced, and then inConnect Using, select Serial: BACnet MS/TP.

b. In COM Port, select the virtual COM port.




Adding a Registry KeyIn some cases with ORCAview, you must add a registry entry to see the devices onthe BACnet network through the eZNx device service port connection:

l with a BACnet MS/TP connection to a network with DNA disabled on thedevice

l eZNT-Wi with a BACnet over UDP/IP connection

To add a registry key:

1. Open the Registry Editor, navigate to WOW6432Node > DeltaControls > 3.40 >Commander > ForceSubscribeNetwork.

2. Add a register key as a Reg_Dword.3. Set the value of the new registry key to 1.4. Restart ORCAview.

Appendix C: List of Tested Wi-Fi RoutersThe following routers were tested and verified to work with the eZNT-Wi:

Appendix D: Time SynchronizationThe thermostat (without Wi-Fi) communicates using MS/TP and behaves like anormal DAC controller connected to the NET2 port of a system controller thatprovides time syncs.

Since the eZNT-Wi thermostat does not connect to the NET2 port of a systemcontroller, you need to enter the network number of the thermostat into the TimeSynchronization Recipients list in the system controller’s DEV object. This allowsthe system controller to act as a time master and send time syncs over theBACnet/IP network at specified intervals, which update the thermostat's real-timeclock (RTC).

The RTC on the eZNT-Wi keeps it time during soft resets and watchdog timerresets. However, when a power cycle (ON-OFF-ON) occurs, the eZNT-Wi loses itstime and reverts to January 1, 2000 at 12 midnight. If the default time of 3600seconds is used in the time master, it may take up to an hour for the RTC to beupdated.

The eZNT-Wi does not support Coordinated Universal Time (UTC) and daylightsaving time.


Appendix E: Glossary of Wi-Fi Terms

Preferred Term Other Usages Explanation

Configurationwebpage

enteliWEBconfigurationpage (wizard)

The eZNT-Wi has a built-in web serverthat provides a configuration webpage.This page can be reached through bothAP Mode and Station Mode.

When configuring with the configurationpage via an AP Mode Wi-Fi connection,an external router is not needed.

Client Stationmode

Station mode Client Station mode is used for normaloperation.

An eZNT-Wi acts as a client where itconnects to a Wi-Fi router. Otherdevices can communicate with theseWi-Fi thermostats through the Wi-Firouter via BACnet/IP. This is calledClient Station (Stn) mode.

On-screenconfigurationmenu

After you enter a password, you cannavigate through a list of menu itemsand make changes. The defaultpassword is 1011.

When the screen is not in theconfiguration menu, you navigatethrough values and adjust setpoints andoperation modes as needed.


Appendix E: Glossary of Wi-Fi Terms


Preferred Term Other Usages Explanation

Device address The default device address is formed byadding the last four digits minus 1(SSID - 1) of the AP mode MAC addressexpressed as a decimal value to thebase BACnet address of the device(4,100,000). For example:

0x447E == (0x447F – 1)

17534 Decimal == 0x447E

(17534) + 4,100,000 = 4,117,534.

SSID Service SetIdentifier

SSID is a 4 digit hex address unique to adevice. When you initially power up aneZNT-Wi, this four digit ID is brieflydisplayed on the screen. This is the lastfour digits of the AP mode MAC addressfor IPS2. IPS1 has a Client Station modeMAC address that is one less than theAP mode MAC address.

Appendix F: eZNx Network Sensor andThermostat DisplayAll the enteliZONE network sensor and thermostat models use the same basicdesign for the case, display, and touch interface. We can alter the physical Mylarbutton layout and use software programming to configure the function of existingdisplay and touch buttons.

The content on the screen display is programmed through GCL.

These eZNx devices use a 7-segment LCD to display numbers and letters.However the limitation of 7 segments restricts how letters are displayed. Thefollowing table shows how lower and upper case letters and numbers arerepresented:
