24 relay outputs, configurable as:
➢Up to 12 independent shutter channels (with or without slats),

➢Up to 6two-pipe fan coil modules where both the fan speed control and
the valve control are performed through relays,
➢A combination of the above.
30 customisable, multi-operation logic functions.
Scene-triggered action control, with an optional delay in the execution.
Manual operation / supervision of the 24 relay outputs through the on-
board pushbuttons and LEDs.
Relay Switches Counter.
Heartbeat or periodical “still-alive” notification.

1.2 INSTALLATION
MAXinBOX 24 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. Element Diagram for MAXinBOX 24.
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 (6) 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 (1 and 2): 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 device packaging 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 consult the next sections of this document for
further details.
On the other hand, when a bus power failure takes place, MAXinBOX 24 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 and fan coil contacts 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
The first parameterisable screen available by default is General. From this screen it is
possible to activate/deactivate all the required functionality.
Figure 2. General screen.
The Manual Control function is enabled by default. Once activated, Inputs, Outputs,
Logic Functions and Manual Control bring additional tabs to the menu on the left. On
the other hand, the user can also activate the functionalities of Sending of Indication
Objects on Bus Voltage Recovery, Heartbeat and Show Relay Switches Counter
Objects. These functions and their parameters will be explained in later sections of this
document.
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): 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.
Show Relay Switches Counter Objects: 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 OUTPUTS
The MAXinBOX 24 actuator incorporates 24 relay outputs, which can be configured
as:
Individual binary outputs, which allows an independent control of loads.
Shutter channels, which allow controlling the motion of shutters or blinds.
Fan Coil modules, which allow the control of the fan and the valve of two-
pipe fan coil units.
In particular:
MAXinBOX 24: the 24 outputs are grouped into two-output channels, which
themselves are grouped into two-channel (or four-output) blocks. Therefore, it
is possible to configure up to 6 fan coil modules, or up to 12 shutter channels,
or up to 24 individual outputs.
For detailed information about the functionality and the configuration of the related
parameters, please refer to the following specific manuals, all of them available within
the MAXinBOX 24 product section at the Zennio website (www.zennio.com):
Individual outputs.
Shutter channels.
‘Relays’ Fan Coil. Note that MAXinBOX 24 is only compatible with two-pipe
fan coils. Therefore, any references to four-pipe fan coils do not apply to this
device.

2.3 MANUAL CONTROL
MAXinBOX 24 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 should be
accessible 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.
Notes:
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
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 either an individual output, as a shutter channel or as a fan coil.
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
