1INTRODUCTION
1.1 MINiBOX 0-10V X3
MINiBOX 0-10V X3 from Zennio is a KNX actuator that aims at fulfilling the climate
control needs of KNX environments with integrated fan coil units where the valves in the
pipes are controlled through analogue 0-10 VDC signals.
The actuator provides three analogue outputs, which permits controlling one fan coil
drive consisting of two or four pipes (each with its own valve) and a fan system.
1 fan coil analog module to control 2 and 4 pipes units with 0-10V fan or
valves.
3 independent 0-10V analog voltage outputs configurable as fan or valve of
a fan coil unit or other adjustable load between these voltage levels.
3 independent thermostats.
10 customisable, multi-operation logic functions.
Manual operation / supervision of the outputs 0-10V through the on-board
pushbuttons and LEDs.
Heartbeat or periodical “still-alive”notification.

1.2 INSTALLATION
MINiBOX 0-10V X3 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 program may be downloaded.
This device does not need any additional external power since it is entirely powered
through the KNX bus.
Figure 1. MINiBOX 0-10V X3. Elements
The main elements of the device are described next.
Test/Prog. Button (4): 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 (1): output ports for the insertion of the stripped cables of the systems
being controlled by the actuator (see section 2.3). 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
Depending on the configuration, some specific actions will 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, MINIBOX 0-10V X3 will
interrupt any pending actions, and will save its state so it can be recovered once the
power supply is restored. Also, after failure recovery, the analog outputs and fan coil
module 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 project, the configuration process begins by entering the Parameters tab
of the device.
ETS PARAMETERISATION
The only parameterisable screen that is always available is “General”. From this screen
it is possible to activate/deactivate all the required functionality.
Figure 2. General.
Fan Coil [disabled/enabled]
1
: enables o disables the “Fan Coil” tab on the left
menu. See section 2.2 for more details.
Analog Voltage Outputs [disabled/enabled]: enables o disables the “Analog
Voltage Outputs” tab on the left menu. See section 2.3 for more details.
Thermostats [disabled/enabled]: enables o disables the “Thermostats” tab
on the left menu. See section 2.4 for more details.
Logic Functions [disabled/enabled]: enables o disables the “Logic Functions”
tab on the left menu. See section 2.5 for more details.

Heartbeat (Periodical Alive Notification) [disabled/enabled]: 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 3. 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.
Manual Control [disabled/enabled]: enables o disables the “Manual Control”
tab on the left menu. See section 2.6 for more details.

2.2 FAN COIL
MINiBOX 0-10V X3 incorporates a module to control the fan and valves of a 2 or 4
pipes fan coil unit via its 0-10V analog voltage outputs.
Please refer to the specific user manual “Fan Coil ‘Analog’”, available in the MINiBOX
0-10V X3 product section, at the Zennio website (www.zennio.com) for detailed
information about the functionality and the configuration of the related parameters.

2.3 ANALOG VOLTAGE OUTPUTS
The MINiBOX 0-10V X3 incorporates three 0-10V analog outputs which can be used
to control fans and valves of a fan coil unit or other adjustable loads or generic outputs
between these voltage levels.
Please refer to the specific user manual “Analog Voltage Output”, available in the
MINiBOX 0-10V X3 product section, at the Zennio website (www.zennio.com) for
detailed information about the functionality and the configuration of the related
parameters.
