1INTRODUCTION
FLAT DISPLAY V2
Flat Display v2 is a KNX multifunction capacitive touch switch with an analogue
display from Zennio with proximity sensor, humidity, luminosity sensor and backlighted
buttons and display.
It is offered at a reduced size and weight, with five capacitive touch buttons on the
bottom, with LED backlight to confirm the press of the buttons or showing states, and a
display on the top.
Flat Display v2 is a fully customisable solution for the room control where the user needs to
control climate systems, lighting, blinds, scenes, etc.
The versatility offered by the functionality of buttons is complemented by the built-in
analogue/digital inputs, the internal temperature sensor, the humidity sensor and the
thermostat function, as well as an elegant and fully customisable design of the front glass –
customers can choose their button icons, texts and colours and even personalise the background
with their pictures, logos, etc.
Moreover, the display offers the possibility of showing useful information to the user
about the control states and object values.
The most outstanding features of Flat Display v2 are:
2.4-inch (2.4’’)back-lit OLED display with a resolution of 128 x 64 pixels.
Fully customisable design of the front glass.
5 touch buttons which can operate as individual or pair controls.
Light indicator (LED) for every button.
Buzzer for an audible acknowledgement of user actions (with the possibility of
disabling it either by parameter or by object).

Possibility of locking / unlocking the touch panel through binary orders or
scenes, and of setting a timed/automatic locking of the device (cleaning
function).
Welcome greeting on the display and Welcome Back object (binary or
scene).
Screensaver function.
Up to 5 switchable languages for the displayed texts.
Two analogue/digital inputs (for motion detectors, temperature probes,
additional switches, etc.).
Thermostat function.
Built-in temperature sensor.
Humidity sensor.
Celsius and Fahrenheit temperature scales for the on-screen indicators,
being possible to select them in parameters or through communication object.
Ambient luminosity sensor for brightness automatic adjustment.
Proximity sensor for quick start.
Heartbeat or periodical “still-alive” notification.

INSTALLATION
Figure 1 shows the connection outilne of the device:
Figure 1. Schematic diagram.
Flat Display v2 is connected to the KNX bus through the built-in terminal (2). An external
DC power supply is not needed.
A short press on the Prog./Test button (4) will make the device enter the programming
mode. The Prog./Test LED (3) will light in red. On the contrary, if this button is held while
plugging the device into the KNX bus, the device will enter the Safe Mode. In such case,
the programming LED will then blink in red.
For detailed information about the technical features of Flat Display v2, as well as on
security and installation procedures, please refer to the Datasheet, bundled within the
device packaging of also available at www.zennio.com.

START-UP AND POWER LOSS
After download or device reset it is necessary to wait for about 2 minutes without
performing any action to make it possible a proper calibration of:
Proximity sensor.
Luminosity sensor.
Button presses.
For a correct calibration of the proximity and brightness sensors it is recommended not
to approach less than 50 cm from the device during this time and to avoid that the light
strikes directly.

2CONFIGURATION
After importing the corresponding database in ETS and adding the device into the
topology of the project, the configuration process begins by entering the Parameters tab
of the device.
GENERAL
To allow the device to perform the desired functions, several options must be
parameterized, either related to its general behaviour (screensaver, sounds, lock
procedure of the touch panel…) or to advanced features (cleaning function, welcome
back object, welcome greeting…).
2.1.1 CONFIGURATION
In the “Configuration" tab, the general settings are displayed.

ETS PARAMETERISATION
Figure 2. Configuration
This tab shows the following parameters:
Buttons [enabled]
1
: read-only parameter to make it evident that the “Buttons”
tab is always enabled in the tab tree on the left. See section 2.2 for details.
Display [enabled]: read-only parameter to make it evident that the “Display”
tab is always enabled in the tab tree on the left. See section 2.3 for details.
Inputs [disabled/enabled]: 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. See section 2.4 for details
Thermostat [disabled/enabled]: enables or disables the “Thermostat” tab in
the tree on the left. See section 2.5 for details.

The default values of each parameter will be highlighted in blue in this document, as follows:
[default/rest of options].

Humidity [disabled/enabled]: enables or disables the “Humidity” tab in the tree
on the left. For more information, see section 2.6
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.
Device Recovery Objects (Send 0 and 1) [disabled/enabled]: this parameter
lets the integrator activate two new communication objects (“[Heartbeat]
Device Recovery”), which will be sent to the KNX bus with values “0” and “1”
respectively whenever the device begins operation (for example, after a bus
power failure). It is possible to parameterise a certain delay [0…255] to this
sending.
Note: after download or bus failure, the sending takes place with a delay of up
to 6,35 seconds plus the parameterised delay, to prevent bus overload.
Time and Date Request Delay [disabled/enabled]: sets a sending delay
[1…65535] [s/min/h] for the date and time request when the device starts up.
Update Objects: enables the sending of read requests to update status objects
and indicators. 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 after the parameterised delay [1…10…65535] [s/min/h].

➢[After Reset]: read request are sent when a reset occurs (bus failure, the
Reset Device ETS option), after the parameterised delay [1…10…65535]
[s/min/h].
➢[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 2.1.1.4 for details.
Run Button Action on Screensaver Exit or Alarm Mute [disabled/enabled]:
sets whether, touching a button while the screensaver or an alarm is active
should cause the execution of the button action, apart from hiding the
screensaver or muting the alarm.
Time to Consider Inactivity [1…30…255] [s/min/h]: time that must elapse
since the last press and/or proximity detection to consider inactivity state. Then
the display and the button LEDs backlight will dim.
Touch Locking [disabled/enabled]: enables or disables the “Touch locking”
tab in the tree on the left. See section 2.1.1.5 for details.
Proximity Sensor [disabled/enabled]: enables the proximity sensor. This
functionality permits “waking up” the device display when detecting presence.
Please refer to the specific manual “Proximity and Luminosity Sensor”
(available in the Flat Display v2 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 2.1.1.6 for details.
Sounds [Default / Custom]: sets whether the sound functions (button beeps,
alarm and doorbell) should work according to the pre-defined configuration or
to a user-defined configuration (see section 2.1.1.7).
Advanced Configuration [disabled/enabled]: enables or disables the
“Advanced” tab in the tree on the left. See section 2.1.2 for details.
The project topology shows the following objects by default:
