1 INTRODUCTION
1.1 KLIC-DA
KLIC-DA from Zennio is the ideal solution for the integration of Altherma climate
systems into a KNX domotic environment.
As a bidirectional KNX / Altherma interface, KLIC-DA provides full communication
between any KNX device (e.g., the InZennio Z41 touch screen from Zennio) and the
Altherma system, which can therefore be controlled analogously as from the specific
Altherma user interfaces. Moreover, any status updates and feedback received from
the Altherma system will also be forwarded by KLIC-DA towards other KNX devices.
Figure 1. KLIC-DA
Daikin Altherma is an integral solution for climate control. Although mainly based on the
heat pump technology, Altherma systems can optionally perform cooling as well,
therefore providing the user with heating, air-conditioning and domestic hot water.
Depending on the structure of the system (e.g.: location of the external unit, integration
or not of the hydrobox within the same unit, etc.) and on whether A/C is required or not,
different Altherma systems are available.

1.1.1 KLIC-DA LT
The KLIC-DA LT application program provided by Zennio focuses on controlling
Altherma LT (from Low Temperature) systems, in contrast to the Altherma HT (from
High Temperature) systems.
An Altherma LT system consists of a series of elements (an external unit, a hydrobox,
an internal unit, the user interfaces, etc.), and the specific “P1/P2” communication bus,
which allows the user interfaces (typically, one acting as the main control and the other
as an additional control) communicate to each other and to the Altherma LT system.
KLIC DA LT is compatible with models CA and CB of Altherma LT system hidrokit.
Note: only the main interface interacts with the Altherma LT system. Any order from or
to the additional interface will reach the main interface too.
KLIC-DA LT is meant to replace the aforementioned additional interface, and thus to
communicate only to the main interface and not to the Altherma LT system directly.
The main functions performed by the KLIC-DA LT application program are:
Management of the domestic hot-water (DHW) system.
Management of the room climate system (Leaving Water Method).
Error handling.
Simultaneous monitoring of multiple indicators (temperature setpoints,
actuator states, sensors…) reported by the Altherma LT system.
On the other hand, Altherma LT systems feature three climate control methods:
Control of the leaving water temperature (LWT),
Control through a user interface configured as a thermostat,
Control though an external thermostat (TH).
The KLIC-DA LT application program is only compatible with Altherma LT systems
configured for an LWT control, and with only one climate zone (Altherma LT systems
permit up to two climate zones with independent setpoint temperatures).

1.2 INSTALLATION
Figure 2. Element Diagram
KLIC-DA connects to the KNX bus via the corresponding built-in terminals (1). On the
other hand, this device needs to be connected to the P1/P2 bus of the Altherma system
(4) in substitution of the original additional user interface.
Once the device is being powered from the KNX bus, both the physical address and
the KLIC-DA LT application program can be downloaded.
This device does not need any additional external power as it is entirely powered
through the KNX bus.
The functionality of the remaining elements is as follows:
Programming Button (3): a short press on this button will set the device into
the programming mode, making the red component of the LED (2) indicator
light up. If the button is held while plugging the device into the KNX bus,
KLIC-DA will go into the safe mode, making the red colour of the LED blink
intermittently.
LED Indicator (2): this three-colour (red, blue and green) light indicator
reflects the current state of the device. Apart from showing whether the
device is under the programming or safe modes, this LED will also react to
any communication between KLIC-DA and the P1/P2 bus, which may be
useful during the installation process. The meaning of the different colour
components is explained next:
1.- KNX Connector
2.- Programming LED
3.- Programming Button
4.- Two-wire Communication Terminal

Red Component (still): KLIC-DA is under the programming mode.
Red Component (blinking): KLIC-DA is under the safe mode.
Green Component (still): KLIC-DA is not connected to the Altherma
system, or the latter is disconnected from the power supply.
Green Component (blinking): transmission or data from the P1/P2 bus
towards KLIC-DA.
Blue Component (blinking): transmission or data from KLIC-DA
towards the P1/P2 bus.
Note: each colour component works with independence of the others.
Therefore, if for instance KLIC-DA is under the programming mode being the
Altherma system disconnected, the effective colour will be orange (still), as
the red and green components will be lighting (still).
Input Terminal for the Two-Wire Communication Cable (4): slot for the
connection of the two-wire communication cable that will connect KLIC-DA to
the Altherma P1/P2 bus.
Figure 3. Connection to the P1/P2 bus
As stated in 1.1.1 and shown in Figure 3, KLIC-DA needs to be installed in
substitution of the original additional user control, while the main user control
needs to be configured as “At Unit” under “User Interface Location”.
For detailed information about the technical features of KLIC-DA, as well as on security
and installation procedures, please refer to the device Datasheet, bundled within the
original packaging of the device and also available at http://www.zennio.com.
