1INTRODUCTION
1.1 inBOX 24 vT / inBOX 20 vT
inBOX 24 vT and inBOX 20 vT from Zennio are two versatile KNX actuators featuring
two relay outputs (together with four analogue-digital inputs, in the case of inBOX 24
vT) and a variety of functions. Their particularly small size makes them suitable for
installation within mechanism boxes, junction boxes, roller shutter boxes or any other
location where the available space is limited.
The most outstanding features are:
2 relay outputs, configurable as:
➢1 shutter channel (with or without slats), or
➢Up to 2 individual ON/OFF outputs.
4 multi-purpose inputs (only in inBOX 24 vT), configurable as:
➢Temperature probe, either models provided by Zennio or other NTC
temperature probes from other suppliers, being in that case possible to
configure their parameters in ETS.
➢Binary inputs (i.e., pushbuttons, switches, sensors),
➢Motion detectors.
10 customisable, multi-operation logic functions.
1 Zennio thermostat (only in inBOX 24 vT).
Scene-triggered action control, with an optional delay in the execution.
Master light control (only in inBOX 24 vT) for an easy, out-of-the-box control
of a set of luminaires (or functionally equivalent devices) one of which acts as
a general lamp and the others as secondary lamps.
Manual operation / supervision of the 2 or 4 relay outputs through the on-
board pushbuttons and LEDs.
Heartbeat or periodical “still-alive”notification.

1.2 INSTALLATION
inBOX 24 / 20 vT connects to the KNX bus through the on-board KNX connector.
Once the device is powered from the KNX bus, both the individual address and the
associated application program may be downloaded.
This device does not need any additional external power since it is entirely powered
through the KNX bus.
Figure 1. inBOX 24 vT. Elements
Note: the above element diagram refers to inBOX 24 vT. It is entirely analogous for
inBOX 20 vT, although the inputs are not available.
The main elements of the device are described next.
Test/Prog. Pushbutton (3): a short press on this button sets the device into
the programming mode, making the associated LED (2) 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 (5): output ports for the insertion of the stripped cables of the
systems being controlled by the actuator (see section 2.3). Please secure the
1. Output status LED.

connection by means of the on-board screws.
Inputs (4): input ports for the insertion of the stripped cables of external
elements such as switches / motion detectors / temperature probes, etc. One
of the two cables of each element needs to be connected to one of the slots
labelled “1” to “4”, while the other cable should be connected to the slot
labelled as “C”. Note that all the external input devices share the “C” slot for
one of the two cables. 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 Test/Prog. 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 consult 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, the shutter channel 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).

2CONFIGURATION
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 screen it is possible to activate/deactivate all the required
functionality.
Figure 2. Default screen
Once activated, Inputs (only on inBOX 24 vT), Outputs, Logic Functions,
Thermostats (only on inBOX 24 vT), Master Light (only on inBOX 24 vT),
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
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): this parameter lets the integrator
incorporate 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 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.
Show Relay Switches Counter Objects [disabled/enabled]: (only on inBOX
20 vT) enables two communication objects to keep track of the number of
switches performed by each of the relays ("[Relay X] Number of Switches")
and the maximum number of switches carried out in a minute ("[Relay X]
Maximum Switches per Minute").

2.2 INPUTS (ONLY inBOX 24 vT)
inBOX 24 vT incorporates four analogue/digital inputs, each configurable as a:
Binary Input, for the connection of a pushbutton or a switch/sensor.
Temperature Probe, to connect a temperature sensor from Zennio or NTC
probes from third parties (the latter requires configuring their parameters in
ETS).
Motion Detector, for the connection of a motion detector from Zennio.
2.2.1 BINARY INPUT
Please refer to the specific user manual “Binary Inputs”, available in the inBOX 24 vT
¡product section, at the Zennio website (www.zennio.com).
2.2.2 TEMPERATURE PROBE

24 vT product section, at the Zennio website (www.zennio.com).
2.2.3 MOTION DETECTOR
It is possible to connect motion detectors from Zennio to the input ports of inBOX 24
vT.
Please refer to the specific user manual “Motion Detector”, available in the inBOX 24
vT product section, at the Zennio website (www.zennio.com), for detailed information
about the functionality and the configuration of the related parameters.

2.3 OUTPUTS
The inBOX 24 / 20 vT actuators incorporate 2 relay outputs, each configurable as a:
Individual binary outputs, which allows an independent control of loads.
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
inBOX 24 / 20 vT product section at the Zennio homepage (www.zennio.com):
Individual outputs.
Shutter channels.
2.3.1 MANUAL CONTROL
inBOX 24 / 20 vT 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
