1 INTRODUCTION
1.1 FLAT v2
Flat v2 is a KNX multifunction capacitive touch switch from Zennio with proximity
sensor, luminosity sensor and backlighted buttons.
It is offered at a reduced size and weight, with one, two, four or six capacitive touch
buttons (according to the user’s needs) with LED backlight to confirm the press of the
buttons as well as showing states.
Flat v2 is a fully customisable solution for the control of rooms where user control of air
conditioning systems, lighting, blinds, scenes, etc. is required.
The versatility offered by the functionality of buttons is complemented by the two built-
in analogue/digital inputs, the internal temperature 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.
The most outstanding features of Flat v2 are:
Fully customisable design of the front glass.
1 / 2 / 4 / 6 touch buttons, which can operate as individual or pair controls:
Horizontally or vertically-oriented configuration (only available for the two-
button and six-button models).
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.
Welcome Back object (binary or scene) which is sent to the KNX bus when
a pulsation is detected after a certain period (configurable) of intactivity.
Built-in temperature sensor.

1.2 INSTALLATION
Figure 1 shows the connection outline of the device:
Figure 1 Schematic diagram.
Flat v2 is connected to the KNX bus through the built-in terminal (6). 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 then light in red. On the contrary, if this button is
held while the device gets connected to the bus, the device will enter the safe mode. In
such case, the programming LED will blink in red colour.
For detailed information about the technical features of Flat v2, 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.

1.3 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:
Proximity sensor.
Luminosity sensor.
Button presses.
For a correct calibration of the proximity and brightness sensors it is recommended not
to remain too close or place anything less than 50cm approximately and do not hit with
direct light to the device during this time.

2 CONFIGURATION
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.
2.1 GENERAL
In order to allow the device to perform the desired functions, a number of options must
be parameterized, either related to its general behaviour (horizontal/vertical
orientation, sounds, LED brightness levels…) or to advanced features (lock procedure
of the touch panel, cleaning function, welcome back object).
2.1.1 CONFIGURATION
In the "GENERAL" tab, the general settings are displayed. Most are checkboxes that
enable/disable other functionalities
ETS PARAMETERISATION
The following parameters are shown:
Device Orientation [Vertical (Normal)
1
/Horizontal (Rotated)]: allows
assigning a horizontal or vertical orientation to the device, making it easier
to identify the push-buttons during the configuration process (ETS will show a
figure with the final distribution of the push-buttons).
To prevent inconsistency in the configuration, please note the following
criterium:
Vertical (normal):
Temperature probe hole
on the right of the bottom
side and the sensors on
the middle of the top side.
Horizontal (rotated):
Temperature probe hole
on the top of the right
side and sensors on the
middle of the left side.
Figure 2 Orientation.

alarm and doorbell) should work according to the pre-defined configuration or
to a user-defined configuration. See section 2.1.4 for details.
Ambient luminosity sensor [disabled/enabled]: enables setting the ambient
luminosity sensor. When the sensor is enabled, a new tab for its configuration
is shown. See section 2.1.5 for details.
Proximity Sensor [disabled/enabled]: enables the proximity sensor. This
functionality permits “waking up” the device when detecting presence.
Please refer to the specific manual “Proximity and Luminosity Sensor”
(available in the Flat v2 product section at the Zennio homepage,
www.zennio.com) for detailed information about the functionality and the
configuration of the related parameters.
Time to Consider Inactivity [1…30…255][s/min/h]: allows setting a time
after which, if no pulsation or proximity detection has occurred, the LEDs turn
off (or acquire the brightness level configured, see section 2.1.3).

2.1.2 TEMPERATURE SENSOR
Flat v2 is equipped with one internal temperature probe which can monitor the
ambient temperature of the room, thus making the device capable of reporting it to the
KNX bus and of triggering certain actions when the temperature reaches specific
values.
Please refer to the specific manual “Temperature Probe” (available in the Flat v2
product section at the Zennio homepage, www.zennio.com) for detailed information
about the functionality and the configuration of the related parameters.
2.1.3 BACKLIGHT
Flat v2 allows managing the brightness of the LED according to two operating modes:
normal mode and night mode.
Please refer to the specific manual “Brightness” (available in the Flat v2 product
section at the Zennio website, www.zennio.com) for detailed information about the
functionality and the configuration of the related parameters.
2.1.4 SOUNDS
It is possible to configure Flat v2 so that a brief beep is emitted as an acoustic
feedback when a button is pressed.
Enabling the button sounds can be done either by parameters or through an object,
being also possible to define in parameters if the button sounds should be initially
enabled or not.
Moreover, Flat v2 can also emit the following sounds on request (through the
corresponding communication objects) if enabled:
Doorbell sounds: a single beep.
Alarm sounds: a sequence of brief beeps with a higher pitch. The sequence
will only stop when the alarm object gets deactivated or when the user
touches any of the buttons (this, moreover the deactivation alarm, will trigger
the button action).
The range of sounds emitted will be different depending on the sound type selected.
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
11
ETS PARAMETERISATION
In case the default button beep sound matches the requirements of the installation and
the doorbell and alarm functions are not necessary, the Sounds parameter in the
general “CONFIGURATION” tab (see section 2.1.1) can be set to “Default”. This will
also imply that the button beeps will be unconditional, as it will not be possible to
disable this function through an object.
On the other hand, if set to “Custom”, a specific tab named “Sounds” will show up in
the tab tree on the left. The initial configuration of this screen is equivalent to the
aforementioned default option. However, the following parameters will be configurable.
Figure 5. Sounds.
The default configuration of this tab is equivalent to the one mentioned above.
However, the following parameters can be customized:
Sound Type [Sound 1/Sound 2]: sets which sounds range incorporates the
device.
Disable button sound [disabled/enabled]: enables the buttons beeping. If
enabled, the following parameters will also be available:
➢ Enable / Disable button sounds through a 1-bit object
[disabled/enabled]: makes it possible to disable / resume the button
beeping function in runtime by writing to a specific object (“[General]
Sounds – Disabling button sound”). If enabled, it will be shown:
• Value [0 = Disabled; 1 = Enabled/1 = Disabled; 0 = Enabled]: allows
configuring the values (0 or 1) that will disable/resume the sounds.
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
12
➢ Status After ETS Download [enabled/disabled]: sets whether the button
beeping function should start up enabled or disabled after an ETS
download.
Object for Doorbell [disabled/enabled]: enables or disables the doorbell
function. If enabled, a specific object (“[General] Sounds - Doorbell”) will be
included into the project topology.
Object for Alarm Bell [disabled/enabled]: enables or disables the alarm
function. If enabled, a specific object (“[General] Sounds - Alarm”) will be
included into the project topology.
2.1.5 AMBIENT LUMINOSITY SENSOR
Flat v2 incorporates a luminosity sensor to receive and monitor ambient brightness
measurement.
Please refer to the specific manual “Luminosity and Proximity Sensor” (available in
the Flat v2 product section at the Zennio homepage, www.zennio.com) for detailed
information about the functionality and the configuration of the related parameters.
2.1.6 ADVANCED
Independent tab for the parameterisation of some advanced functions. These functions
are explained next.
ETS PARAMETERISATION
After enabling the Advanced configuration from “General” screen (see section 2.1.1),
a new tab will be incorporated into the tree on the left.
Figure 6. Advanced.
Touch locking: enables or disables the “Touch locking” tab in the tree on the
left. See section 2.1.6.1 for details.

13
Welcome back object: enables or disables the “Welcome back” tab in the
tree on the left. See section 2.1.6.2 for details.
2.1.6.1 TOUCH LOCKING
The touch panel of Flat v2 can be optionally locked and unlocked anytime by writing a
configurable one-bit value to a specific object provided for this purpose. It can also be
done through scene values.
While locked, pressing on the buttons will be ignored: no actions will be performed (and
no LEDs will change their states) when the user touches on any of the controls.
ETS PARAMETERISATION
After enabling Touch Locking in “ADVANCED” tab, a new tab will be incorporated into
the tree on the left.
Figure 7. Touch Locking.
Control of this function comprises two non-exclusive checkboxes to select how the
touch panel lock/unlock should be performed:
Figure 8. Touch Locking: Control.
Control Object: 1-Bit [disabled/enabled]: when marked, a specific drop-
down list will show up to select which value should trigger which action.
➢ Value [0 = Unlock; 1 = Lock/0 = Lock; 1 = Unlock]: these values are
received through the object “[General] Touch Locking”.
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
14
Scene Object [disabled/enabled]: when marked, two specific textboxes will
show up to enter the scene numbers (1 - 64) that should trigger each action.
These values are to be received through the general “[General] Scene:
Receive” object.
2.1.6.2 WELCOME BACK OBJECT
Flat v2 can send a specific object (the welcome back object) to the KNX bus when the
user presses a touch button after a significant amount of time since the last or
presence detection (when the proximity sensor is enabled). Sending it or not can also
depend on an additional, configurable condition consisting in the evaluation of up to
five binary objects.
Any actions that in normal operation may be executed will not be if the welcome back
object is sent to the bus. Thus, if the user presses a button and this causes that the
welcome back object is sent, the normal action of that button will not be triggered.
On the other hand, if the additional condition is not evaluated to true, the device will
react normally. Hence, the action corresponding to the button touch will be executed.
The welcome back object can consist in a one-bit value or a scene value (or both),
depending on the parameterisation.
ETS PARAMETERISATION
After enabling Welcome Back Object, a new tab will be incorporated into the tree on
the left.
Figure 9 Welcome Back Object.
This screen contains the following parameters:
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
15
Timeout to Activate the Welcome Object [1…255][s/min/h]: sets the
minimum time that should elapse after the last button touch touch (or
presence detection, when the proximity sensor is enabled) before the next
one triggers the execution of the welcome back function.
Sending Trigger [Push Button/Proximity Detection]: sets whether the
welcome back object is sending after a touch in the screen or when the
proximity sensor detects presence.
Additional Condition: sets if sending the welcome back object should also
depend on an external condition. The option by default is “[No Additional
Condition]. The following are available too:
➢ [Do not send unless all additional conditions are 0]: the welcome back
object will only be sent if all the condition objects are found to have the
value “0”.
➢ [Do not send unless all additional conditions are 1]: the welcome back
object will only be sent if all the condition objects are found to have the
value “1”.
➢ [Do not send unless at least one of the additional conditions is 0]: the
welcome back object will only be sent if at least one of the condition
objects is found to have the value “0”.
➢ [Do not send unless at least one of the additional conditions is 1]: the
welcome back object will only be sent if at least one of the condition
objects is found to have the value “1”.

2.2 BUTTONS
As indicated in previous sections, Flat v2 has one, two, four or six capacitive
buttons (depending on the model) at the user’s disposal for the execution of actions.
The distribution of the buttons will depend on the model, being possible to configure
them as single-button controls or in pairs by combining any two of them.
There are some differences in the button configuration depending on the model:
Flat 1 v2: due to the existence of only one push button, only one individual
control is possible (two-button controls are not available). Moreover, it can
only be configured under the normal (vertical) orientation.
Figure 11 Flat 1 v2
Flat 2 v2: up to two one-button controls can be configured, or either one two-
button control, under any of the two orientations.
Figure 12 Flat 2 v2. Normal orientation (left) and rotated (right).
Flat 4 v2 up to four one-button controls can be configured, or up to two two-
button controls (by combining any two buttons for each pair). The figure
shows which number identifies each button during the configuration process.
Figure 13 Flat 4 v2
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
18
Flat 6 v2: up to six one-button controls, or three two-button controls (by
combining any two push buttons for each pair) can be configured, under any
of the two orientations. The figure shows which number identifies each button
during the configuration process.
Figure 14 Flat 6 v2. Normal orientation (left) and rotated (right).
2.2.1 CONFIGURATION
The following is a list of the functions that can be assigned to each button.
Disabled (the button will not react to user presses).
Pair A, B or C (the number of available pairs depends on the selected
model), being the function of such pair one of the following:
➢ Switch (binary).
➢ Two objects (short press /
long press).
➢ Light dimmer.
➢ Shutter.
Individual (one-button control):
➢ Switch (Binary).
➢ Hold & release.
➢ Two objects (short press /
long press).
➢ Scene.
➢ Scaling constant.
➢ Counter constant.
➢ Float constant.
➢ Light dimmer.
➢ Shutter.
➢ LED indicator.
➢ Room State
Apart from the button function itself, the desired behaviour of the button LEDs can be
set. The different illumination modes have been detailed in ANNEX I. LED Illumination
Modes.
The next sections explain the configuration involved for each of the above functions.
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
19
ETS PARAMETERISATION
An independent tab for the parameterisation of the buttons is shown in ETS by default,
initially containing only a sub-tab named Configuration.
Figure 15 Buttons - Configuration
One drop-down list with the following options is shown per button:
[Disabled]. See section 2.2.2 for details.
[Individual]. Selecting this option brings a new tab (“Button Ix”, where “x”
depends on the button), which will make it possible to configure the
functionality of that particular touch button. See section 2.2.3 for details.
[Pair X]. Sets that this touch button will belong to a two-button control (where
X is A, B or C, depending on the model). Once one pair has been assigned to
Flat 1/2/4/6 v2
http://www.zennio.com Technical Support: http://support.zennio.com
20
two buttons (and not before), a new tab (“Pair X”) will show up in the tab tree,
in order to configure the desired functionality. See section 2.2.4 for details.
A drop-down list (LED Illumination Control (All buttons)) is provided at the bottom of
the window so a joint behaviour can be configured for the illumination of the LEDs. The
options are (please refer to ANNEX I. LED Illumination Modes for details):
➢ [Regular]
➢ [State-Dependent (where available)]
➢ [State-Dependent (where available) (both LEDs)]
➢ [Dedicated Object]
➢ [Configure every button (pair) separately]: in case of selecting the last
option, there will be a specific parameter for each control to specifically
select the desired behaviour of the LED (or LEDs).
Figure 16 Buttons - Configuration - Advanced options.
Finally, if at least one two-button control is being configured (either Pair A or Pair B), an
additional parameter (Action of the pair buttons (all pairs)) will be available to
determine an operation criterion. The options are:
➢ [Left = Off/Down/Decrement; Right = On/Up Increment]
➢ [Right = Off/Down/Decrement; Left = On/Up Increment]
➢ [Every button pair is configured separately]
2.2.2 DISABLED
While a button stays disabled, it will not be functional: touching on it will not cause the
execution of actions, nor will make the associated LED light.
