1 Configuration Page (optionally), which contains the controls for setting the
time/date, for calibrating the built-in temperature probe and for pairing the
device with a remote IP application. It also shows the alarm log, the software
version and the current IP address.
1.3 INSTALLATION
Figure 1 shows the connection outline of the InZennio Z41 screen:
Figure 1Element Diagram
The InZennio Z41 touch screen connects to the KNX bus through the built-in terminal
(1). To ensure that enough supply is provided as to power all the internal components
of the device, it is also necessary to connect an external DC power supply of 12, 24 or
29v which delivers at least 150 mA of current. The KNX power and the external power
must be electrically isolated and provided by separate supplies, in order to avoid
interference to the KNX bus.
This external power must be supplied to the device through the corresponding terminal
(4) provided within the original packaging, ensuring that each cable is properly
connected and respecting the electrical polarities –positive and negative– from the
supply to the device.
In addition to the external supply, Z41 makes use of a button battery (LR44), located
at the corresponding slot (7), to help maintain the time and date updated in case of a
failure of the external power supply.

Note: immediately after connecting the external supply, the device will perform an
automatic calibration, which may result deviated if it takes place while any type of
pressure is being made over the front panel. In case of an unexpected behaviour in
touch recognition, it will be necessary to disconnect and connect the device back,
avoiding making pressure over the panel, in order to perform a new calibration.
After the connection of the external power supply, the screen will blink for an instant.
Approximately 7 seconds later, a welcome message containing the Zennio logo and
the “Loading…” label will be shown. Once the load process ends, the Status page will
come up (see Figure 2).
Figure 2 Status Page
This screen is divided into 8 boxes:
The “KNX” box shows the individual address assigned to the screen (in case
of no assignment, this will show as “x.x.x”).
The “Software” box will show empty in absence of an application program. In
general, it will indicate if the download software is correct (“OK”) or if it is
found to be corrupt due to download issues (“ERROR”).
The “Sync” box shows, as a percentage, the progress of the internal
synchronisation of the device during the start-up. Once it reaches 100%, the
Status page will disappear and the Menu page will come up.
The “Ethernet” box shows the IP address assigned to Z41, provided that an
Ethernet cable has been attached (6) and the network is running a DHCP
server.

InZennio Z41
http://www.zennio.com Tecnical Support: http://zennioenglish.zendesk.com
11
Last, the “SW Version” box shows the version of the application program
currently loaded to the device.
The Status page will also show up during bus failures in case the external power (12-
24-29v) is not interrupted.
Note: although the device will not turn functional until it is powered with the external
supply, the KNX bus power should be enough to perform downloads from ETS
(application program, group addresses, etc.).
A brief press on the programming button (2) will make the device enter the
programming mode. The programming LED (3) will then light in red. On the contrary,
if this button is held while the device gets connected to the bus, Z41 will enter the safe
mode. In such case, the programming LED will blink in red colour.
Connectors (5) and (6) are provided for firmware updates (see section 1.3.1) and most
likely for enhanced functionality such as remote accesses to the device.
For detailed information about the technical features of Z41, as well as on security and
installation procedures, please refer to the device Datasheet, included within the
device packaging and also available at http://www.zennio.com.
1.3.1 FIRMWARE UPDATES
Z41 incorporates two separete microcontrollers. One of them is focused on
interfacing with the KNX bus and on running the application program itself, while the
second one is dedicated to running the firmware that implements the operating system
and the management of the peripherals.
Therefore, an eventual update of Z41 may consist in two phases:
Downloading the new application program (from ETS),
Downloading the new firmware.
Two alternative methods are provided for the latter: the connection of a flash memory
drive to the USB slot (see 6 in Figure 1) through the proper adapter, or the connection
of an Ethernet network cable (see 6 in Figure 1). For further details on the firmware
update process, please refer to the “Z41 – USB/Ethernet firmware update” specific
document, available at http://www.zennio.com.

2CONFIGURATION
2.1 MENU PAGE
The user interface of the InZennio Z41 touch screen is organised into pages (up to
eight different pages), each of which can be accessed from the Menu page, which
(unless parameterised the contrary) is automatically shown after the start-up of the
device.
Figure 3 Menu Page (example)
As Figure 3 shows, the access to the pages is provided by a set of icons, which may
show other (smaller) icons overlaid, such as an exclamation or a lock. Exclamations
reflect that there are active alarms (see epigraph f) in section 3.4.2.5) within the page,
while a lock reflects that the access to the page is password-protected (see section
3.2.2).
On the other hand, 6 out of the 8 pages are general-purpose pages at the entire
disposal of the integrator, who may include up to 8 controls/indicators (with different
functionalities) per page, being even possible to combine alarm, climate or any other
controls within the same page, in contrast to previous versions of the application
program. The remaining two pages (Profile and Configuration) are specific-purpose,
as they are provided for user customisation of the device in runtime.
The user interface permanently shows a top bar containing the name of the current
page as well as the current time and temperature. A button can be also found at the
bottom of every page to get back to the Menu page:

InZennio Z41

Figure 4 Menu button
2.2 GENERAL-PURPOSE PAGES
The integrator can make use of up to 6 general-purpose pages, each of which can hold
up to 8 different indicators or controls (with no restrictions for combining them) which
will show inside the pages, automatically distributed or not, according to page
parameterisation. For more details on the box distribution, refer to section 2.6.
The parameterisable controls for the general-purpose pages and their behaviour will be
described in detail in section 3.
2.3 PROFILE PAGE
The Profile page lets the final user perform certain adjustments on the visual and
audible side of the user interface:
Figure 5 Profile Page
The specific controls that can be made available for the Profile page are:
Contrast.
Brightness.

InZennio Z41
http://www.zennio.com Tecnical Support: http://zennioenglish.zendesk.com
14
Theme: desired colour combination, among eight different options:
Figure 6 Themes
Melody: desired tune (among three different options) for the beeps emitted
on button presses or as a feedback on action executions. One more
possibility is to make these beeps silent (however alarm beeps will still work).
Note that the labels of the controls in the Profile page, as well as the title of the page
itself, are customisable in ETS. Moreover, it is possible to make any of the described
controls remain hidden for the final user. These details are explained in section 3,
together with the entire parameterisation process.

InZennio Z41
http://www.zennio.com Tecnical Support: http://zennioenglish.zendesk.com
15
2.4 CONFIGURATION PAGE
The Configuration page lets the user know or adjust certain technical values about the
device.
Figure 7 Configuration Page
The specific controls that can be made available for the Configuration page are:
Date / Time: even though the device implements two communication objects
(see section 3.1) for setting the internal time and date from an external
device, they can also be adjusted (if such option has been enabled by
parameter) directly from the user interface. Therefore, by pressing this button,
a set of controls will pop up to let the user set the current hour (0-23),
minutes, day, month and year.
Figure 8 Time-Set Control
Z41 features an internal clock powered by a battery (see section 1.3),
because of which the time/date will not be lost after downloads or reboots.
Programming Button: control/indicator that shows the status of the
programming LED of the device. In particular, it permits entering/leaving the

InZennio Z41
http://www.zennio.com Tecnical Support: http://zennioenglish.zendesk.com
16
programming mode as by pressing the actual programming button of the
device (see section 1.3) in case the rear of Z41 cannot be accessed.
Reset: holding this button for a few seconds (i.e., a long press is required)
sets the device back to a certain state, which can be set in ETS:
ETS Reset Device: similar to a device reset from ETS, with the
subsequent reset of the object values, alarm controls, timers, etc.
Z41 Reboot: simple device reset, with no data loss (zeroing).
ETS Reset Device and Z41 Reboot: the above two, combined.
Note: alarm logs, consumption logs or any other historic logs are not reset to
zero in any case (such thing takes only place after a firmware download; see
section 1.3.1). Nevertheless, a device reset from ETS does reset any
adjustment performed by the final user from the Profile and Configuration
pages (excepting the time / date, which is controlled by an internal clock).
Alarm Log: log file where alarm events will be incorporated as soon as they
occur. This centralised file may be useful when the user needs to check the
status of a set of alarm controls distributed across several pages.
Figure 9 Alarm Log
Hence, the alarm log will contain a listing, in reverse chronological order,
where the name, time and date of every alarm event will be shown. In
addition, the log will show the current status of each of them, which may be:

InZennio Z41
http://www.zennio.com Tecnical Support: http://zennioenglish.zendesk.com
17
“ON”: the alarm is still active or has not been acknowledged by the
user.
“OK”: the user has acknowledged the alarm event, but the
corresponding object is still in the alarm state.
“OFF”: the user has acknowledged the alarm event and the
corresponding object has already left the alarm state.
For more information on alarms, see epigraph f) in section 3.4.2.5.
IP Address: in case the device has been connected to an IP network through
an Ethernet cable (see section 1.3), the IP address it has been assigned (if
any) will be shown here.
Version: indicator that shows both, the version of the device firmware (on the
left) and, next to it, the version of the application program that have been
downloaded to the device (see section 1.3.1).
Probe Calibration: control for setting a certain correction over the values
thrown by the internal temperature probe. This way, if the value of the
measurement is found to be slightly over (or below) the actual temperature
due to external factors, the final user will have the option to set an adjustment
of between -5.0ºC and +5.0ºC, in steps of 0.1ºC. In addition, it is possible to
set an initial value for such correction by parameter.
Note: any changes made on the calibration of the internal probe will be
applied beginning with the next measurement performed. Therefore, they
may not be perceived immediately.
Device Pairing: button for entering the device pairing function, which needs
to be run once on every Z41 that is intended to be controlled from a remote IP
application. See ANNEX I. Controlling Z41 Remotely via for more details
about controlling Z41 remotely.
The labels of the controls in the Configuration page, as well as the title of the page
itself, are customisable in ETS. Moreover, it is possible to make any of the described
controls stay hidden for the final user. These details are explained in section 3,
together with the entire parameterisation process.

InZennio Z41
http://www.zennio.com Tecnical Support: http://zennioenglish.zendesk.com
18
2.5 BACKLIGHT
In order to prevent unnecessary power consumptions while the device is idle, Z41
automatically fades partially out the backlight of the screen after two minutes without
any user interaction. Next, after three more minutes of inactivity (i.e., after five minutes
of inactivity), the backlight is completely turned off. W hile partially or totally faded out,
any press on the screen will bring back the normal light level.
The above timings do not apply while a pop-up window is open or if a particular
backlight configuration has been parameterised (see section 3.2.1).
2.6 PAGE SHAPING
Each of the pages of the user interface –including Menu, Profile and Configuration–
can be independently parameterised to display its control/indicator boxes statically
distributed or automatically ordered.
Static (grid) Distribution: all the 8 boxes of the page will be shown,
remaining empty those not having been assigned a function.
Figure 10 Static Distribution
Automatic Distribution: the active boxes will be dynamically ordered, so that
they make use of all the available space. The final layout of the page will
therefore depend on the number of boxes having been assigned a function.

3ETS PARAMETERISATION
To begin with the parameterisation of InZennio Z41, once the ETS program is running it
is necessary to import the product database (Z41 application program). Next, the
device is added to the project and, after right-clicking on the name of the device, the
option “Edit parameters” must be selected to start the configuration process.
The next sections explain in depth the ETS parameterisation of the device.
Note: the number of characters permitted for text parameters (labels, etc.) may vary
depending on whether special characters (symbols, accents…), coded with more than
one byte, are being used or not. ETS does not dynamically adjust the width of this
parameters, because of which a warning may be shown afterwards stating that the limit
has been exceeded, even if the textbox is still showing free spaces.
Important: whenever the device is updated to a new version of the application program
from ETS, it is also necessary to update the firmware of the secondary microcontroller
(responsible for the operating system; see section 1.3.1) in case an updated version
exists. Should the installed versions of the application program and the firmware not
match each other, the device may not work correctly (and may cause that the Software
box in the Status page shows the label “incompatible”).
3.1 DEFAULT CONFIGURATION
This section illustrates the default initial state of the device.
Figure 12 Default Topology
The general objects enabled by default are:
[General] Time: 3-byte object for externally (for example, by linking it to a
KNX clock) setting the internal time of the device. This object also permits
read requests, so the current time of the device can be checked. It is also
automatically sent after time changes made by the user from the screen itself.
