1.2 INSTALLATION
MINiBOX 20 connects to the KNX bus through the on-board KNX connector.
Once the device is provided with power from the KNX bus, both the individual address
and the associated application programme may be downloaded.
This device does not need any additional external power since it is entirely powered
through the KNX bus.
Figure 1. MINiBOX 20. Elements.
The main elements of the device are described next.
Prog./Test Pushbutton (5): a short press on this button sets the device into
the programming mode, making the associated LED (5) light in red.
Note: if this button is held while plugging the device into the KNX bus, the
device will enter into safe mode. In such case, the LED will blink in red every
0.5 seconds.
Outputs (6): output ports for the insertion of the stripped cables of the
systems being controlled by the actuator (see section 2.2). Please secure the
connection by means of the on-board screws.
To get detailed information about the technical features of this device, as well as on the
installation and security procedures, please refer to the corresponding Datasheet,
bundled with the original package of the device and also available at www.zennio.com.

1.3 START-UP AND POWER LOSS
During the start-up of the device, the Prog./Test LED will blink in blue colour for a few
seconds before the device is ready. External orders will not be executed during this
time, but afterwards.
Depending on the configuration, some specific actions will also be performed during
the start-up. For example, the integrator can set whether the output channels should
switch to a particular state and whether the device should send certain objects to the
bus after the power recovery. Please refer to the next sections of this document for
further details.
On the other hand, when a bus power failure takes place, the device will interrupt any
pending actions, and will save its state so it can be recovered once the power supply is
restored. For safety reasons, all shutter channels will be stopped (i.e., the relays will
open) if a power loss takes place, while the individual outputs will switch to the specific
state configured in ETS (if any).

2. CONFIGURATION
2.1 GENERAL
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.
ETS PARAMETERISATION
From the General parameter screen it is possible to activate/deactivate all the required
functionality.
Figure 2. General
Once activated, Outputs, Logic Functions, Scene Temporisation and
Manual control bring additional tabs to the menu on the left. These functions
and their parameters will be explained in later sections of this document.
The Manual Control function is enabled by default, and so is the
corresponding configuration tab.
Sending of Indication Objects (0 and 1) on Bus Voltage Recovery: this
parameter lets the integrator activate two new communication objects (“Reset
0” and “Reset 1”), which will be sent to the KNX bus with values “0” and “1”
respectively whenever the device begins operation (for example, after a bus

MINiBOX 20

8
power failure). It is possible to parameterise a certain delay to this sending (0
to 255 seconds).
Figure 3. Sending of Indication objects on bus voltage recovery
Heartbeat (Periodical Alive Notification): incorporates a one-bit object to
the project (“[Heartbeat] Object to Send ‘1’”) that will be sent periodically
with a value of “1” to notify that the device is still working (still alive)..
Figure 4. Heartbeat (Periodical Alive Notification).
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 match
the period set.

2.2 OUTPUTS
MINiBOX 20 incorporates 2 relay outputs, configurable as:
Individual binary outputs, which allows an independent control of loads.
One shutter channel, which allow controlling the motion of shutters or blinds.
For detailed information about the functionality and the configuration of the related
parameters, please refer to the following specific manuals, all of them available in the
MINiBOX 20 product section at the Zennio homepage (www.zennio.com):
Individual outputs.
Shutters.
2.2.1 MANUAL CONTROL
MINiBOX 20 allows manually switching the state of its output relays through the
respective pushbuttons on the top of the device. A specific pushbutton is therefore
available per output.
Manual operation can be done in two different ways, named as Test On Mode (for
testing purposes during the configuration of the device) and Test Off Mode (for a
normal use, anytime). Whether both, only one, or none of these modes can be
accessed needs to be parameterised in ETS. Moreover, it is possible to enable a
specific binary object for locking and unlocking the manual control in runtime.
Note:
The Test Off mode will be active (unless it has been disabled by parameter)
after a download or a reset with no need of a specific activation –the
pushbuttons will respond to user presses from the start.
On the contrary, switching to the Test On mode (unless disabled by
parameter) needs to be done by long-pressing the Prog./Test button (for at
least three seconds), until the LED is no longer red and turns yellow. From
that moment, once the button is released, the LED light will remain green to
confirm that the device has switched from the Test Off mode to the Test On

MINiBOX 20
http://www.zennio.com Technical Support: http://support.zennio.com
10
mode. After that, an additional press will turn the LED yellow and then off,
once the button is released. This way, the device leaves the Test On mode.
Note that it will also leave this mode if a bus power failure takes place.
Test Off Mode
Under the Test Off Mode, the outputs can be controlled through both their
communication objects and the actual pushbuttons located on the top of the device.
When one of these buttons is pressed, the output will behave as if an order had been
received through the corresponding communication object, depending on whether the
output is configured as an individual output or as a shutter channel.
Individual output: asimple press (short or long) will make the output switch
its on-off state, which will be reported to the KNX bus through the
corresponding status object, if enabled.
Shutter Channel: when the button is pressed, the device will act over the
output according to the length of the button press and to the current state.
A long press makes the shutter start moving (upwards or downwards,
depending on the button being pressed). The LED will light in green until
the end of the motion. If the button gets pressed being the shutter already
at the top or bottom positions, nothing will happen (the LED will not light).
A short press will make the shutter drive stop (if in motion), as it normally
does when a step/stop order is received from the KNX bus. In case of not
being the shutter in motion, pressing the button does not cause any action,
unless slats/lamellas have been parameterized –in such case, a step
movement (up/down, depending on the button pressed) will take place.
The status objects will be sent to the bus when corresponding.
Disabled output: outputs disabled by parameter will not react to button
presses under the Test Off mode.
Regarding the lock, timer, alarm and scene functions, the device will behave under the
Test Off mode as usual. Button presses during this mode are entirely analogous to the
reception of the corresponding orders from the KNX bus.

11
Test On Mode
After entering the Test On mode, it will only be possible to control the outputs through
the on-board pushbuttons. Orders received through communication objects will be
ignored, with independence of the channel or the output they are addressed to.
Depending on whether the output has been parameterised as an individual output or as
part of a shutter channel, the reactions to the button presses will differ.
Individual output: short or long pressing the button will commute the on-off
state of the relay.
Shutter channel: pressing the button will make the shutter drive move
upward or downward (depending on the button) until the button is released
again, thus ignoring the position of the shutter and the parameterised times.
Note:after leaving the Test On mode, the status objects will recover the
values they had prior to entering Test On. As the device is never aware of the
actual position of the shutter (as the shutter drive does not provide any
feedback), these values may not show the real position. This can be solved
by performing a complete move-up or move-down order, or by calibrating the
shutter position in the Test On mode until it matches the status objects.
Disabled output: short and long presses will switch the state of the
corresponding relay. In case this consists in closing the relay, then the
remaining relays will open, for safety reasons.
The lock, timer, alarm and scene functions will not work while the device is under the
Test On mode. Status objects will not be sent to the bus, either.
Important: the device is delivered from factory with all the output channels configured
as disabled outputs, and with both manual modes (Test Off and Test On) enabled.

ETS PARAMETERISATION
The Manual Control is configured from the Configuration tab itself under Manual
Control.
The only two parameters are:
Figure 5. Manual control screen
Manual Control: options are “Disabled”, “Only Test Mode Off”, “Only Test
Mode On” and “Test Mode Off + Test On Mode” (default). Depending on the
selection, the device will permit using the manual control under the Test Off,
the Test On, or both modes. Note that, as stated before, using the Test Off
mode does not require any special action, while switching to the Test On
mode does require long-pressing the Prog./Test button.
Lock Manual Control: unless the above parameter has been “Disabled”, the
Lock Manual Control parameter provides an optional procedure for locking
the manual control in runtime. When this checkbox is enabled, object
“Manual Control Lock” turns visible, as well as two more parameters:
Value: defines whether the manual control lock/unlock should take place
respectively upon the reception (through the aforementioned object) of
values “0” and “1”, or the opposite.
Initialisation: sets how the lock state of the manual control should remain
after the device start-up (after an ETS download or a bus power failure):
“Unlocked”, “Locked” or “Last Value” (default; on the very first start-up, this
will be Unlocked).

2.3 LOGIC FUNCTIONS
This module makes it possible to perform numeric and binary operations to incoming
values received from the KNX bus, and to send the results through other
communication objects specifically enabled for this purpose.
MINiBOX 20 can implement up to 10 different and independent functions, each of
them entirely customisable and consisting in up to 4 consecutive operations each.
The execution of each function can depend on a configurable condition, which will be
evaluated every time the function is triggered through specific, parameterisable
communication objects. The result after executing the operations of the function can
also be evaluated according to certain conditions and afterwards sent (or not) to the
KNX bus, which can be done every time the function is executed, periodically or only
when the result differs from the last one.
Please refer to the “Logic Functions” user manual, available within the MINiBOX 20
product section at the Zennio homepage, www.zennio.com, for detailed information
about the functionality and the configuration of the related parameters.

2.4 SCENE TEMPORISATION
The scene temporisation allows imposing delays over the scenes of the outputs.
These delays are defined in parameters, and can be applied to the execution of one or
more scenes that may have been configured.
Please bear in mind that, as multiple delayed scenes can be configured for each
individual output / shutter channel, in case of receiving an order to execute one of them
when a previous temporisation is still pending for that output / channel, such
temporisation will be interrupted and only the delay and the action of the new scene will
be executed.
ETS PARAMETERISATION
Prior to setting the scene temporisation, it is necessary to have one or more scenes
configured in some of the outputs. When entering the Configuration window under
Scene Temporization, all configured scenes will be listed, together with a few
checkboxes to select which of them need to be temporised, as shown in Figure 6.
Figure 6. Scene temporisation

MINiBOX 20
http://www.zennio.com Technical Support: http://support.zennio.com

Enabling a certain scene number n brings a new tab with such name to the menu on
the left, from which it is possible to configure the temporisation of that scene for each of
the outputs where it has been configured.
Figure 7. Configuration of the scene temporisation
Therefore, parameter “Scene m. Z Delay” defines the delay that will be applied to the
action defined in Z for the execution of scene m (where Z may be a specific individual
output or shutter channel). The range of this delay is 0 to 3600 seconds, 0 to 1440
minutes or 0 to 24 hours.
