1.3 INSTALLATION
Figure 1 shows the connection outline of the device:
Figure 1. Schematic diagram.
Z35 isconnected to theKNX bus through the built-in terminal (6). An external DC power
supply is not needed.
A short press on the Prog./Test button (7) will make the device enter the programming
mode. The Prog./Test LED (8)will then light in red. On the contrary, if this button is held
while the device gets connected to the bus, Z35 will enter the safe mode. In such case,
the programming LEDwill blink in red colour.
For detailed information about the technical features of Z35, as well as on security and
installation procedures, please refer to the device Datasheet, bundled within the device
packaging and also available at www.zennio.com.

1.4 START-UP AND POWER LOSS
After download or device reset it is necessary to wait for about 2 minutes without
performing any action in order to make it possible a proper calibration of the proximity
sensor and luminosity sensor.
It is recommended not to approach less than 50 cm from the device during this time and
to avoid that the light strikes directly.

2UPDATE OBJECTS AFTER RESET
The aim of this functionality is allowing the integrator to make a read request to the
statuses of the device objects after a reset. There are two situations in which this
functionality may be useful:
In case of a Z35 reset, if there have been changes in the bus while the Z35 was
off, after the reset, the objects in Z35 keep the same value as before the reset,
but not their actual value in the installation.
In addition, after programming from ETS, all objects are initialized to their default
values, but not to their actual values in the installation.
When abus failure orETS programming occurs, read requests of all thefollowing objects
will be sent gradually (to prevent bus overload):
General objects: date and time, scene (reception), disabling pushbuttons,
cleaning function, external temperature, backlightmode, brightness, pulse sound
enable and temperature scale.
Indicator objects.
Timer enabling objects.
Alarm confirmation object.
Ventilation control: Auto mode dedicated object.
14-byte Text indicator.
RGB and RGBW objects.
Objects that will NOT be updated are:
Control objects.
Alarm trigger.
4-Bit Light Dimming.
4-Bit RGB/RGBW Dimming.
Shutter: Stop/Step.
The time and date objects of Z35 will be read from the bus always after a reset,
regardless of whether this functionality is active or not.

3CONFIGURATION
After importing the corresponding database in ETS and adding the device into the
topology of the desired project, the configuration process begins by entering the
Parameters tab of the device.
3.1 MAIN CONFIGURATION
This tab is divided into multiple screens, all of which contain a set of global parameters
regarding the general functionality of the device, and therefore not specifically related to
a particular page of the user interface.
3.1.1 GENERAL
The "General" tab contains general settings. Most are checkboxes for enabling/disabling
other functionalities.
ETS PARAMETERISATION
Figure 2. General.

Z35
http://www.zennio.com Tecnical Support: http://support.zennio.com
13
The following parameters are shown:
Inputs [disabled/enabled]
1
: enables or disables the “Inputs” tab in the tree on the
left, depending on whether the device will or will not be connected any external
accessories. For more information, see section 3.5.
Thermostats [disabled/enabled]: enables or disables the “Thermostat” tab in the
tree on the left. For more information, see section 3.6.
Heartbeat (Periodic Alive Notification) [disabled/enabled]: incorporates a one-
bit object to the project (“[Heartbeat] Object to Send ‘1’”) that will be sent
periodically with value “1” to notify that the device is still working (still alive).
Figure 3. Heartbeat.
Note: the first sending after download or bus failure takes place with a delay of
up to 255 seconds, to prevent bus overload. The following sendings march the
period set.
Home Button Enabled [disabled/enabled]: enables or disables the home button
to access to the menu page.
Show Time [disabled/enabled]: permits setting whether the current time
(according to the internal clock) is displayed in the upper-left corner of any page
or not.
Show Temperature [No / Internal Temperature Probe / External Value]: sets
whether the current temperature should show or not in the upper right corner of
every page, being necessary in such case to choose the source of the
temperature value: “Internal temperature probe” or “External value”. If the latter
is chosen, an object named “[General] External temperature”will be enabled,
so that it can be grouped with any other object that sends temperature values.

14
Button Box Style [No frame / Colored frame / Black frame]: permits selecting a
frame for the buttons of controls and pages, in order to distinguish them from the
indicators.
Figure 4. Button box (black, white color, no box).
Global Color Mask [White / Color select by dropdown]: permits selecting the
color that will be applied to all the elements of the screen in a general way.
Note: It is possible to set a different color in the desired boxes and buttons by
using a specific parameter in their configuration tab (see section 3.3.2).
First Weekday [Monday / Sunday]: sets the first day of week on calendar.
Weekdays initials [MTWTFSS]: permits customising the label that will represent
each of the weekdays on the screen. A seven-character string (including letters
or numbers), ordered according to the above First Weekday parameter, must be
entered –each of the characters will represent one weekday.
Hour Update Request Delay [disabled/enabled]: sets a sending delay
[1…65535] [s/min/h] for the date/time request when the device starts up.
Update Objects [Disabled/After Programming/After Reset/After Programming
and Reset]: enables the sending of read requests to update status objects and
indicators (see section 2 for further details). There are four options available,
some of them with a configurable delay:
“Disabled”: no read request, therefore objects are not updated.
“After Programming”: read requests are sent after a complete or partial
download (or when pressing the reset button in theconfiguration page, if set
as “Parameters Reset”, see section 3.4), after the parameterised delay
([0…10…65535] [s/min/h]).
“After Reset”: read request are sent when a reset occurs (bus failure, the
Reset Device ETS option or when pressing the reset button in the
configuration page, if set as “Z35 Reboot”, see section 3.4), after the
parameterised delay ([0…10…65535] [s/min/h]).

Z35
http://www.zennio.com Tecnical Support: http://support.zennio.com
15
“After Programming and Reset”: combination of the two above options.
Screensaver [disabled/enabled]: enables or disables the “Screensaver” tab in
the tree on the left. See section 3.1.6 for details.
Time to Consider Inactivity [1…65535] [s/min/h]: time that must elapse since
the last press and/or proximity detection to consider inactivity state. Then the
display backlight will dim. See section 3.1.3.
Proximity Sensor [disabled/enabled]: enables the proximity sensor. This
functionality permits “waking up” the device display when detecting presence
through the proximity sensor
Please refer to the user manual “Proximity and Luminosity Sensor” (available
in the Z35 product section at the Zennio homepage, www.zennio.com) for
detailed information about the functionality and the configuration of the related
parameters.
Ambient Luminosity Sensor [disabled/enabled]: enables or disables the
ambient luminosity sensor. When enabled, a new tab is added in the tree on the
left (see section 3.1.7).
Touch Locking [disabled/enabled]: enables or disables the possibility of locking
the touch by object.When enabled, a new tab is added in thetreeon theleft (see
section 3.1.8).
Sounds [Default/Custom]: sets whether the sound functions (button beeps,
alarm and doorbell) should work according to the pre-defined configuration
(“Default”) or to a user-defined configuration (“Custom”) (see section 3.1.9).
Advanced Configuration [enabled/disabled]: enables or disables the
“Advanced” tab in the tree on the left (see section 3.1.10).
The project topology shows the following objects by default:
[General] Time: 3-byte object for setting the internal time of the device, for
example, by linking it to a KNX clock. This object also allows 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.
Note: although the DPT of this object considers a field for setting the day of the
week, Z35 calculates it from the date and therefore ignores that field.

Z35
http://www.zennio.com Tecnical Support: http://support.zennio.com
16
Important: Z35 does not have an RTC clock or battery to keep track of the
time in the absence of power. Therefore, it is important to receive the time
periodically from a device that obtains it through NTP and/or has a battery to
prevent delays during bus failures.
[General] Date:3-byte object for setting the internal date of the device, for
example, by linking it to a KNX clock. This object also allows read requests, so
the current date of the device can be checked. It is also automatically sent after
date changes made by the user from the screen itself.
[General] Scene: Receive and [General] Scene: Send: objects for respectively
receiving and sending scene values from/to the KNX bus whenever it is
necessary (e.g., when theuser touches abutton that has been configured to send
scene commands; see section 3.3.2.2.4).
[General] Activity: 1-bit object to force activity/inactivity state on the device. For
further information, please refer to the user manual “Proximity and Luminosity
Sensor” and “Brightness” (available in the Z35 product section at the Zennio
homepage, www.zennio.com).
[General] Display - Brightness: 1-byte percentage object for changing the
display brightness level.
[General] Proximity Sensor, [General] External Proximity Detection and
[General] Proximity Detection: 1-bit object whose functionality is tied to the
proximity sensor. For further information, please refer to the user manual
“Proximity and Luminosity Sensor” (available in the Flat Display product
section at the Zennio homepage, www.zennio.com).
[General] Translations - Select Language: 1 and 2-byte objects for changing
the language showed in the screen when receiving a value through the bus (see
section 3.1.2).
[General] Translations - Main Language: 1-bit object that, after the reception
of the value “1” from the bus, will load the main language (see section 3.1.2).
[General] Temperature Scale: 1-bit object which permits changing in runtime
the scale of the temperatures that may show on the screen (see section 3.1.10).

Z35
http://www.zennio.com Tecnical Support: http://support.zennio.com
17
[Internal Temp. Probe] Current Temperature: 2-byte object through which the
value of the current measurement of the built-in sensor will be sent to the bus,
according to the parameterisation (see section 3.1.5).

3.1.2 TRANSLATIONS
Texts shown on the screen can be translated into up to five different languages.
Texts of page titles, box titles, indicators, etc. are entered by parameter in the
corresponding configuration tab. For each language enabled, an additional textbox is
displayed to enter the translation.
Note: depending on the space occupied by the charactere on the screen, the full text
entered may not be displayed.
Switching from language to another can be done through two types of communication
objects:
Up to five 1-bit objects, one for each language. If this is enabled, when a “1” is
received through any of this, the corresponding language is activated in the
device.
A 1-byte scene object. The expected values in this object are fixed, from 0 to 4,
to select the language. If the corresponding language to the received value is not
enabled, the texts will be displayed in the main. If an out-of-range value is
received, it does not change the active language.
A 2-byte ASCII object. The expected values for this object are two characters of
the ASCII code, corresponding to ISO 639-1. If the received character pair does
not correspond to any enabled language, thetexts will be represented in the main
language.
Note: please refer to http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes for a
table with the language codes.
On the other hand, Z35 allows the use of Latin, Greek and Cyrillic characters for the texts
displayed on the screen.

3.1.3 BACKLIGHT
Z35 allows managing the brightness of the display according to two operating modes:
normal mode and night mode.
Note: Contrast is not a configurable feature in the device.
Please refer to the specific manual “Brightness” (available in the Z35 product section at
theZenniowebsite, www.zennio.com) for detailed information about thefunctionality and
the configuration of the related parameters.
3.1.4 SECURITY
Any box or page will be given the possibility of restricted access by password. Setting
one or two different passwords is possible, so the integrator can afterwards configure
whether the access to a page or box will be protected by one password or another, or
remain unprotected –every page can be independently configured.
Buttons that lead to a protected page or box will show a little lock icon overlaid on their
lower left corner.
Figure 6 shows the “enter password” dialog shown to the user when trying to access a
protected page.
Figure 6. Security Pop up.
In case of setting up two levels, the first one is assumed to be enclosed by the second
one. This means that whenever the device asks the user to type password #1 (to enter
acertain page); password #2 will also be accepted. On thecontrary, password #1 cannot
beused instead of password #2. This behaviour permits, therefore, making password #2
available to users with further privileges while password #1 is assigned to users with
fewer privileges.
