1INTRODUCTION
1.1 PRESENTIA C v2
Presentia C v2 from Zennio is a device that aims at, among other functions, the
detection of presence, the measurement and control of the room luminosity and the
detection of occupancy within the room where it has been installed. It has been
designed for ceiling or false ceiling mounting by means of the bundled accessories.
The most outstanding features of Presentia C v2 are:
4 sensorswith configurable sensitivities.
4 LEDs to indicate motion.
Presence detection:
➢6 presence detection channels.
➢Luminosity-dependent presence detection (optional).
➢Periodic and delayed sendings (binary, scene, HVAC, percentage).
Occupancy detection:
➢1x occupancy detection channel.
➢Master / slave configuration.
➢Trigger upon door opening or closing.
➢Periodic and delayed sendings (binary, scene, HVAC, percentage).
Luminosity measurement:
➢Configurable correction factor and offset.
➢Periodic sending or upon value change.
2 constant light control channels with configurable setpoints.
10 customisable, multi-operation logic functions.
Heartbeat or periodic “still alive” notification.
Day / night configuration.

1.2 INSTALLATION
Presentia C v2 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. Presentia C v2. Elements
The main elements of the device are described next.
Programming button (5): a short press on this button sets the device into
the programming mode, making the associated LED (2) light in red.
Note: if this button is held while plugging the device into the KNX bus, the
device will enter the safe mode. In such case, the LED will blink in red every
0.5 seconds.
Detection notification LEDs (3): each of them emits a light flash whenever
the sensor associated to that zone observes motion.

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, the Test/Prog. LED will blink in blue colour for one
minute before the motion sensors are ready.
Depending on the configuration, some specific actions will also be performed during
the start-up. For example, the integrator can set whether the detection channels should
start up enabled or disabled. 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
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 window of the device.
ETS PARAMETERISATION
From General screen it is possible to activate/deactivate all the required functionality.

: enables the “Presence Detector” tab in the
tree on the left. For more information, see section 2.2.
Logic Functions [enabled/disabled] enables or disables the “Logic
Functions” tab in the tree on the left. For more information, see section 2.3.
Heartbeat (Periodic Alive Notification) [enabled/disabled]: 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).

2.2 PRESENCE DETECTOR
Presentia C v2 incorporates six independent presence detection channels, two more
for constant light control and one for occupancy detection.
Presence detection consists in sending objects to the bus whenever the
device observes a moving body (or no longer observes it) in the environment
of the room where it has been installed.
Constant light control consists in sending KNX orders to the dimmer device
that controls the in-room luminaries so the ambient light level remains
constant even if other light sources are present.
Occupancy detection is an algorithm that allows determining, through a
multiple sensor configuration, whether a particular space is under occupation
no matter if the occupant moves or not (i.e., no matter if the device is
detecting presence in the room or not).
Please refer to the specific manual “Presence Detector” available in Presentia C v2
product section at the Zennio website (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.
Presentia C v2 can implement up to 10 different and independent functions, each of
them entirely customisable and consisting of up to 4 consecutive operations.
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 “Logic Functions” user manual available under the Presentia C v2
product section at the Zennio homepage (www.zennio.com) for detailed information
about the functionality and the configuration of the related parameters.
