1INTRODUCTION
1.1 MINiBOX 0-10V X3/X2/X1
MINiBOX 0-10V from Zennio is a KNX actuator that aims at fulfilling the climate control
needs of KNX environments with integrated fan coil units consisting of two or four
pipes, where the valves in the pipes and the fan are controlled through analog 0-10
VDC signals.
This document describes the three versions of the device: MINiBOX 0-10V X3 (3
channels) / MINiBOX 0-10V X2 (2 channels) / MINiBOX 0-10V X1 (1 channel) and all
their characteristics will be mentioned respectively and following this order along the
entire document.
3 / 2 / 1 fan coil analog modules to control 2 and 4 pipes units with 0-10V fan
or valves.
3 / 2 / 1 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 / 2 / 1 independent analog inputs capable of measuring voltage (0…1V,
0…10V or 1…10V) and current (0…20mA or 4…20mA) signals.
3 / 2 / 1 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
The MINiBOX 0-10V devices connect 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
Note: the previous figure is analogous for MINiBOX 0-10V X2 and MINiBOX 0-10V X1
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.
Inputs/Outputs (1): inputs/output ports for the insertion of the stripped cables
of the systems being controlled by the actuator (see sections 2.2 and 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, the MINiBOX 0-10V devices
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. The following image
corresponds to the MINiBOX 0-10V X3. The reduced versions only show the number of
channels corresponding to each device.

Channel X [disabled/input/output]
1
: enables or disables the “Analog Inputs”
(see section 2.2) and/or “Analog Voltage Outputs” (see section 2.3) tabs on the
left menu.
Fan Coils [disabled/enabled]: enables or disables the “Fan Coil” tab on the left
menu. See section 2.4 for more details.

The default values of each parameter will be highlighted in this document, as follows:
[default/rest of options].

Thermostats [disabled/enabled]: enables or disables the “Thermostats” tab
on the left menu. See section 2.5 for more details.
Logic Functions [disabled/enabled]: enables or disables the “Logic Functions”
tab on the left menu. See section 2.6 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.
Device Recovery Objects (Send 0 and 1) [disabled/enabled]: this parameter
lets the integrator activate two new communication objects (“[Heartbeat]
Device Recovery”), which will be sent to the KNX bus with values “0” and “1”
whenever the device begins operation (for example, after a bus power failure).
It is possible to parameterise a certain delay [0…255][s] to this sending.
Figure 4. Device Recovery Objects.
Note: After download or bus failure, the sending takes place with a delay of up
to 6,35 seconds plus the parameterised delay, to prevent bus overload.
Manual Control [disabled/enabled]: enables o disables the “Manual Control”
tab on the left menu. See section 2.7 for more details.

2.2 ANALOG INPUT
The MINiBOX 0-10V X3/X2/X1 devices incorporate three/two/one analog inputs which
can be used to connect different sensors with different voltage (0-10V, 0-1V y 1-10V) or
current (0-20mA y 4-20mA) measurement ranges.
Please refer to the specific user manual “Analog Inputs”, available in the MINiBOX 0-
10V product sections, at the Zennio website (www.zennio.com) for detailed information
about the functionality and the configuration of the related parameters.

2.3 ANALOG VOLTAGE OUTPUT
The MINiBOX 0-10V X3/X2/X1 devices incorporate three/two/one 0-10V analog
outputs which can be used to control fans and valves of a fan coil unit or other
adjustable loads that operate between these voltage levels, by the configuration of
generic outputs.
Please refer to the specific user manual “Analog Voltage Output”, available in the
MINiBOX 0-10V product sections, at the Zennio website (www.zennio.com) for detailed
information about the functionality and the configuration of the related parameters.
2.3.1 OPERATING TIME COUNTER
When an analog output is enabled, it is possible to configure the operating time
counter, a function that offers the possibility to record the time the output is on or off.
It is possible to select the counting mode, as wells as reading and updating the counters
values by directly acting over the enabled objects (for example, the user can reset the
counters by writing the value 0 in any of the objects, which will update both objects at
the same time).
ETS PARAMETERISATION
When the Operating Time Counter option is enabled on an analog voltage output type
channel, a tab on the left menu appears, in which the following parameters are available:
