1 INTRODUCTION
1.1 MAXinBOX 24
MAXinBOX 24 from Zennio is a versatile KNX actuator featuring a wide variety of
functions:
24 relay outputs, configurable as:
➢ Up to 12 independent shutter channels (with or without slats),
➢ Up to 24 individual ON/OFF outputs,
➢ Up to 6 two-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).

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
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").
