1INTRODUCTION
1.1 HeatingBOX
HeatingBOX from Zennio is a heating-specific KNX actuator equipped, with four or eight
independent outputs for controlling 24V or 230V valves, depending on the device.
The most outstanding features are:
4 or 8 configurable outputs for controlling electromechanical valves.
A sole 230 VAC or 24 VAC/VDC power input for all outputs.
4 or 8 independent thermostats (one per output).
10 customisable, multi-operation logic functions.
Manual operation / supervision of the outputs through the on-board
pushbuttons and LEDs.
Heartbeat or periodical “still-alive” notification.

1.2 INSTALLATION
HeatingBOX 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.
Figure 1. HeatingBOX 230V 8X.
Note: the above element diagram is slightly different for HeatingBOX 230V / 24V 4X,
although entirely analogous.
The main elements of the device are described next.
Test/Prog. Pushbutton (5): 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.
Phase Inputs (1): slots for the connection of the voltage lines (phase). Both
inputs are internally shorted.

Outputs (2): output ports for the insertion of the stripped cables of the systems
being controlled by the actuator. Please secure the connection by means of the
on-board screws.
Manual control pushbuttons (3):pushbuttons for a direct control of the
outputs during the set-up process. See section 2.5.
To get detailed information about the technical features of this device, as well as on the
installation process and on security procedures, please refer to the corresponding
Datasheet, bundled with the original packaging of the device and also available at
www.zennio.com.
1.3 START-UP AND POWER LOSS
During the start-up of the device and depending on the configuration, some specific
actions may be performed. For example, the integrator can set whether the outputs
should change to a particular position 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.

2CONFIGURATION
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.
2.1 GENERAL
From the “General” screen it is possible to activate/deactivate all the required
functionality.
ETS PARAMETERISATION
Figure 2. General screen
Heartbeat (Periodic Alive Notification) [disabled/enabled]
1
: incorporates 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).

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.
Thermostats [disabled/enabled]: enables or disables the “Thermostats” tab in
the tree on the left. See section 2.2 for details.
Logic Function [disabled/enabled]: enables or disables the “Logic Functions”
tab, which contains specific parameters for the case the Logic Functions
module is required. See section 2.3 for details.
Heating Controls [enabled]: read-only parameter to make it evident that the
“Heating Controls” tab is always enabled in the tab tree on the left. See section
2.4 for details.
Manual Control [disabled/enabled]: enables or disables the “Manual Control”
tab in the tree on the left. See section 2.5 for details.

2.2 THERMOSTATS
HeatingBOX implements four or eight Zennio thermostats, depending on the device
outputs number, which can be enabled and configured independently.
Please refer to the specific “Zennio Thermostat” user manual (available in the
HeatingBOX product section at the Zennio homepage, www.zennio.com) for detailed
information about the functionality and the configuration of the related parameters.

2.3 LOGIC FUNCTIONS
This module makes it possible to perform numeric and binary operations to incoming
values received from the KNX bus, and to send the results through other communication
objects specifically enabled for this purpose.
HeatingBOX can implement up to 10 different and independent functions, each of
them entirely customisable and consisting in up to4 consecutive operations each one.
The execution of each function can depend on a configurable condition, which will be
evaluated every time the function is triggered through specific, parameterisable
communication objects. The result after executing the operations of the function can also
be evaluated according to certain conditions and afterwards sent (or not) to the KNX
bus, which can be done every time the function is executed, periodically or only when
the result differs from the last one.
Please refer to the specific “Logic Functions” user manual (available in the HeatingBOX
product section at the Zennio homepage, www.zennio.com) for detailed information
about the functionality and the configuration of the related parameters.
