1 INTRODUCTION
1.1 KLIC-DD3
KLIC-DD3 from Zennio is a gateway that provides full-duplex communication between
the KNX home automation system and domestic range Daikin air-conditioning
systems through the S21 port of interior units.
Because of this bidirectional communication, the air conditioning system can be
controlled from the home automation system in the same manner as it is through its
own controls. Moreover, the actual status of the unit can be monitored and periodically
sent to the KNX bus to inform other devices.
The most outstanding features of KLIC-DD3 are:
Bidirectional control of domestic range Daikin A/C units through the S21 port
of interior units.
Control of the main functions of the domestic range Daikin A/C unit: On/Off,
temperature, mode of operation, fan speed, swing of the flaps, etc.
Error management to handle specific error codes from the A/C unit itself as
well as any communication issues that may arise.
Up to five scenes.
Three analogue-digital inputs, for the connection of temperature probes,
motion detectors or binary pushbuttons or switches.
10 customisable, multi-operation logic functions.
Heartbeat or periodical “still-alive” notification.

1.2 INSTALLATION
Figure 1. Element scheme.
KLIC-DD3 connects to the KNX bus via the corresponding built-in terminal (5). Once
the device is provided with power from the KNX bus, both the physical address and the
KLIC-DD3 application program can be downloaded.
This device does not need any external power as it is entirely powered through the
KNX bus.
The remaining elements are described next.
Prog./Test button (2): a short press on this button will set the device into the
programming mode, making the associated LED (1) light in red.
Note: if this button is held while plugging the device into the KNX bus, the
device will enter into safe mode. The LED will blink in red every 0.5 seconds
Analogue-Digital Inputs (3): input ports for the stripped cables of external
elements such as switches, motion detectors, temperature probes, etc.
Communication cable (4): 5-wire cable with S21 connector that will connect
KLIC-DD3 and the A/C unit. The other end of the cable, therefore, is intended
to be connected to the S21 connector in the PCB board of the internal unit.

Figure 2. Connecting KLIC-DD3 to the A/Cunit.
Important: Control the A/C unit both through its incorporated wired remote control and
through KLIC-DD3 is not possible, due to both of them use the S21 port. By the other
hand, if the wireless control is employed, it must be taken into account that orders sent
from the wireless control will have a higher priority than those sent through KLIC-DD3.
In addition, certain parameterisations made in the device can be ignored.
For detailed information about the technical features of KLIC-DD3, as well as on
security and installation procedures, please refer to the device Datasheet, bundled in
the device packaging and also available at http://www.zennio.com.
1.3 START-UP AND POWER LOSS
Depending on the configuration, some specific actions will be performed during the
device start-up. The integrator may set up an initial status to be sent to the A/Cunit
after the bus power recovery, and whether certain objects should be sent to the bus
after the power recovery, as described in later sections.
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.

2 CONFIGURATION
2.1 GENERAL
The general configuration of the device consists in enabling the specific functionalities
that will be required during normal operation:
Heartbeat or periodical “still-alive” notification.
Inputs: see section 2.2.
Logic functions: see section 2.3.
AC gateway: see section 2.4.
The latter entails all functions specific to KLIC-DD3, i.e., all the functions related to
interfacing with the A/C unit and to the management of the climate control system.
ETS PARAMETERISATION
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.
The General screen is shown in the first place, containing the following parameters:
Figure 3. General.
Enabling Inputs, Logic Functions and AC Gateway brings additional tabs
into the menu on the left. These functions and their parameters will be

explained in later sections of this document. Please note that AC Gateway is
permanently enabled.
Heartbeat (Periodical Alive Notification): 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).
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.
Figure 4. Heartbeat.
Regardless of the above parameters, the following objects are available by default:
“[AC] On/Off” and “[AC] On/Off (Status)”: allow switching on (value “1”) and
off (value “0”) the A/C unit or reading the current status, respectively.
“[AC] Temperature Setpoint” and “[AC] Temperature Setpoint (Status)”:
allow setting the desired temperature setpoint or reading the current value,
respectively. See section 2.4.1 for further options.
“[AC] Mode” and “[AC] Mode (Status)”: allow setting the desired operation
mode (either Automatic, Heating, Cooling, Fan or Dry) or reading the current
mode, respectively. See section 2.4.1 for further options.
“[AC] Fan: Percentage Control” and “[AC] Fan: Percentage Control
(Status)”: allow setting one of the 5 fan levels or auto mode (automatic, fan 1,
fan 2, fan3, fan 4 or fan 5) or reading the current fan level, respectively. See
section 2.4.1.
Several error objects. See section 2.4.4.

2.2 INPUTS
KLIC-DD3 incorporates three analogue/digital inputs, each configurable as a:
Binary Input, for the connection of a pushbutton or a switch/sensor.
Temperature Probe, for the connection of a temperature sensor from
Zennio.
Motion Detector, for the connection of a motion detector (models ZN1IO-
DETEC-P and ZN1IO-DETEC-X from Zennio).
Important: older models of the Zennio motion detector (e.g., ZN1IO-DETEC
and ZN1IO-DETEC-N) will not work properly with KLIC-DD3.
ETS PARAMETERISATION
When Inputs has been activated in the General parameters screen, the following dropdown lists will be available for the selection of the specific functions required.
Figure 5. Inputs. Configuration.

2.2.2 TEMPERATURE PROBE
Please refer to the “Temperature Probe” user manual, available in the KLIC-DD3
product section, at the Zennio website (www.zennio.com).
2.2.3 MOTION DETECTOR
It is possible to connect motion detectors (models ZN1IO-DETEC-P and ZN1IO-
DETEC-X from Zennio) to the input ports of KLIC-DD3.
Please refer to the “Motion Detector” user manual, available in the KLIC-DD3 product
section, at the Zennio website (www.zennio.com).
Notes:
The ZN1IO-DETEC-P motion detector is compatible with a variety of Zennio
devices. However, depending on the device it is actually being connected to,
the functionality may differ slightly. Therefore, please refer specifically to the
corresponding product section to obtain the aforementioned document.
Motion detectors with references ZN1IO-DETEC and ZN1IO-DETEC-N are
not compatible with KLIC-DD3 (may report inaccurate measurements if
connected to this device).
When connected to KLIC-DD3, the rear micro-switch of model ZN1IO-
DETEC-P should be set to position “Type B”.

2.3 LOGIC FUNCTIONS
This module makes it possible to perform numeric and binary operations with incoming
values received from the KNX bus, and to send the results through other
communication objects specifically enabled for this purpose.
KLIC-DD3 can implement up to 10 different and independent functions, each of
them entirely customisable and consisting in up to 4 consecutive operations each.
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 in the KLIC-DD3 product
section at the Zennio homepage, www.zennio.com) for detailed information about the
functionality and the configuration of the related parameters.

2.4 AC GATEWAY
2.4.1 CONFIGURATION
KLIC-DD3 allows controlling and monitoring an air-conditioning unit in the same way it
would be through the wired remote control it is provided with.
Through the KNX bus, KLIC-DD3 can be sent orders to control the following basic
functions of the air conditioning unit:
On/Off switch of the air-conditioning unit.
Operation mode: automatic, heating, cooling, fan and dry.
Temperature setpoint, which can be modified within a specific range of
values, depending on the capabilities of the specific A/C unit being controlled.
Fan speed: 5 levels and automatic mode.
Flaps swing: vertical flaps, horizontal flaps or both types depending on A/C
unit.
Moreover, KLIC-DD3 allows configuring several advanced functions:
Initial configuration, which allows establishing the desired initial parameters
for the state of the A/C unit after programming or restarting the device.
Setpoint limits, to restrict the range for the temperature setpoint.
Automatic off, which allows an automatic and temporary switch-off of the
unit (after a pre-established delay, if desired) when the communication object
associated to this function is triggered due to a certain event.
Scenes, which allows defining specific climate control presets, to be sent to
the machine on the reception of scene orders from the KNX bus.
These functionalities imply changes in the state of the A/C unit, which therefore notifies
KLIC-DD3 periodically about the current state. When KLIC-DD3 is notified about a
change, it updates the status objects and sends them to the KNX bus. In addition,
