1INTRODUCTION
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.

2CONFIGURATION
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:

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

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,

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
12
KLIC-DD3 provides an error management function (see section 2.4.4), which allows
sending messages to the KNX bus in case the A/Cunit reports any errors.
ETS PARAMETRIZATION
The Configuration window under AC Gateway provides the following parameters:
Figure 6. AC Gateway. Configuration.
OPERATION MODES
KLIC-DD3 allows controlling the A/C unit operating mode through the following objects,
available by default:
“[AC] Mode”: 1-Byte object which allows selecting the A/C unit operation
mode. There will be only taken in account values that are appropriated with
some of available modes in Daikin units, which are represented in Table 1.

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com

Table 1. A/C unit operating modes.
Note: In case of having selected humidifying unit, other additional modes will be
available. See paragraph Humidity in this section.
Additionally a simplified mode can be configured to select Cooling and Heating mode.
Simplified Mode: in addition to the “Mode” and “Mode (Status)” one-byte
objects, available by default, it is possible to commute and to verify the
current operation mode through the following one-bit objects, which get
enabled after activating this parameter:
“Simplified Mode”, which allows switching to the Cooling mode by
sending it a “0” and to the Heating mode by sending it a “1”.
“Simplified Mode (Status)”, which will send a value of “0” when the
mode switches to Cooling or to Dry, or a value of “1” when it switches
to Heating. The Fan mode is not reflected in the value of this object. In
Auto mode the value will be actualized depending of the current mode
operating: Auto-Cooling (“0”) or Auto-Heating (“1”).
FLAPS
Flaps control consists on activating or deactivating the swing.
Horizontal Flaps:when enabled, “[AC] Horizontal Flaps: Swing” and
“[AC] Horizontal Flaps: Swing (Status)” 1-bit objects will be available in
order to commute or consult the operating state.

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
14
Vertical Flaps:when enabled, “[AC] Vertical Flaps: Swing” and “[AC]
Vertical Flaps: Swing (Status)” 1-bit objects will be available for commuting
or consulting the operating state.
In both cases the parameter Swing Object Polarity is available to define which value
activates each swing (“0 = Swing On; 1 = Swing Off” or “0 = Swing Off; 1 = Swing On”).
Figure 7. AC Gateway. Configuration. Flaps.
VENTILATION
The Fan function allows sending the A/C unit orders to switch the ventilation speed
along the available levels (5 levels and automatic mode). To that end, KLIC-DD3
provides a percentage control through the objects “[AC] Fan: percentage control” y
“[AC] Fan: percentage control (Status)”, available by default.
Table 2 reflects the percentage values that refer to several ventilation levels:

Table 2: Fan Speed.
In addition, automatic fan speed mode can be activated through the following
parameter:

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
15
Individual object for automatic mode: enables the “[AC] Fan: Automatic”
and “[AC] Fan: Automatic (Status)” one-bit objects, which will let
activating/deactivating the automatic mode or reading the current status,
respectively. Moreover, the polarity can be configured by parameter:
Automatic Mode Object Polarity: sets the polarity of the above objects:
“0 = Automatic On; 1 = Automatic Off”or “0 = Automatic Off; 1 = Automatic
On”.
Figure 8. AC Gateway. Configuration. Fan.
If individual object for automatic mode is enabled, the behaviour is as follows:
When activating automatic mode, fan percentage status will be 0%.
When deactivating automatic mode, fan level 1 is set.
Notes:
In automatic mode, effective fan speed it is not possible to know the effective
fan speed, so, when activated, fan speed status will stay with 0% value.
In dry mode, A/C unit sets fan speed in automatic mode. Due to this fact the
fan speed control orders will be ignored during this mode.
TEMPERATURE SETPOINT
The following objects to control and supervise setpoint temperature will be available by
default:
“[AC] Temperature Setpoint”: 2-Byte object that allow selecting decimal
temperature values that belong to the range [10º-32º].

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
16
“[AC] Temperature Setpoint (Status)”: 2-Byte object that provides the
Temperature setpoint status.
Note: A X.Y value will be rounded to X.0 if [Y < 5] or to X.5 if [Y ≥ 5].
Status object will be updated to the last setpoint temperature value received by the A/C
unit after a complete communication cycle and will be sent to KNX bus every time that
its value changes.
Setpoint limits can be configured by parameter:
Setpoint Limits: allows restricting the range of the temperature setpoint
(from below in the Cooling, Dry and Auto modes and from above in the
Heating and Auto modes), provided that the limits are still within the
predefined limits of the A/C unit. When KLIC-DD3 receives an order to send
the A/C unit a setpoint which is greater (or lower) than the configured limits, it
will actually send the limit value.
Minimum (Cooling / Auto / Dry Mode): sets the upper limit.
Maximum (Heating / Auto Mode): sets the lower limit.
Figure 9. AC Gateway. Configuration. Temperature setpoint.
Once these limits are enabled, several objects to modify them at run time will be
available. The values of this objects will be restrict to an interval which is defined by the
absolute limits established by the A/C unit (10ºC to 32ºC).
“[AC] Temperature Setpoint: Lower Limit”: 2-Byte object that allows
changing the lower limit at run time.
“[AC] Temperature Setpoint: Lower Limit (Status)”: 2-Byte object with the
lower limit current value.

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
17
“[AC] Temperature Setpoint: Upper Limit”: 2-Byte object that allows
changing the upper limit at run time.
“[AC] Temperature Setpoint: Upper Limit (Status)”: 2-Byte object with the
upper limit current value.
Notes:
If [Minimum] ≥ [Maximum], limits will not be taken in account in Auto mode
due to the incongruity. In this case, default values will be used.
These parameters only can be set as integer values in ETS. However, at run
time the associated objects allow decimal values.
The A/C unit set a fixed temperature setpoint in Fan and Dry mode, this is the
reason why KLIC-DD3 will not send the setpoint value to A/C unit, however
the value will be save to send when leaving these modes.
The setpoint limits set by the A/C unit on each operating mode are indicated
in Table 3:

HUMIDITY
The availability of humidity control depends on A/C unit model and can be activated by
the parameter:
Humidifying Unit: enables humidity control function.

Once the humidifying unit is enabled in AC Gateway Configuration section, the
following objects are available:
“[AC] Humidity Adjust: Operation Point (%)”: 1-Byte object to select the
desired humidity operation point. Table 4 represents the percentage values
that refer to each of the 5 humidity operation points.
“[AC] Humidity Adjust: Operation Point (%) (Status)”: 1-Byte object that
provides the humidity operation point.
Note: A humidity operation point can only be established when the current operating
mode allows humidity control (Cooling, Heating and Dry mode). In Automatic or Fan
mode the humidity cannot be controlled. So, if a humidity operation point is sent during
these modes, it will be ignored.

Table 4. Humidity operation levels.
Domestic range Daikin A/C units with humidity control, allow other operation modes
apart from traditional modes (Auto, Fan, Cooling, Heating and Dry):
Ururu humidification operation: this operation permits to raise the humidity.
This mode can only be activated while A/C unit is off (if an order of Ururu
activation is received while the unit is on, it will be ignored). To activate the
Ururu humidification operation or to supervise its status, the following objects
are available:
“[AC] Ururu”: 1-bit object to activate or deactivate Ururu humidification.
“[AC] Ururu (Status)”: 1-bit object that provides Ururu humidification
status.

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
19
Once Ururu humidification is activated, A/C unit turns on, activates Heating
mode and the humidify process starts. Fan speed level will remain and
temperature setpoint will not be accessible (in case of modifying temperature
setpoint while this mode is running, Ururu humidification mode will be
deactivated, and Humid heating operation, that will be explain later, will be
activated).
When deactivating Ururu humidification mode (by sending “0” through its
object) or when sending “0%” humidity adjust, the A/C unit will operate in
Heating mode.
Note: After bus failure and/or after a programming, Ururu humidification
mode, in case of being configured, will be deactivated.
Humid heating operation: this operation permits to raise the temperature
and humidity. The ways to active this operation are:
While in Heating mode, modifying the humidity adjust.
While in Ururu humidification mode, modifying the temperature setpoint.
Once Humid heating is operating, heating mode and a low humidity operation
point will be activated. Fan speed level is not modified, keeping its previous
value.
Sarara Drying Operation: this operation permits to lower humidity (actually,
is the same functionality than Dry mode).
To activate Sarara Drying operation, there are available the next objects:
“[AC] Sarara: 1-Bit object to activate or deactivate Sarara Drying
operation.
“[AC] Sarara (Status)”: 1-Bit object that provides Sarara Drying
operation status.
Once Sarara drying operation is activated, Dry mode and a low humidity
operation point will be established. Fan speed level will be set to Automatic
and temperature setpoint will not be accessible (in case of modifying
temperature setpoint while this mode is running, Sarara drying mode will be

KLIC-DD3
http://www.zennio.com Technical Support: http://support.zennio.com
20
deactivated, and Dry cooling mode, that will be explain after, will be
activated).
Note: Activating Sarara drying operation involves activating Dry mode and
vice versa.
When deactivating Sarara drying operation (by sending “0” through its object)
or when sending “0%” humidity adjust, the A/C unit will operate in Cooling
mode.
Dry cooling operation: this operation permits to lower temperature and
humidity. The ways to active this operation are:
While in Cooling mode, modifying humidity adjust.
While in Sarara Drying operation, modifying temperature setpoint.
Once Dry cooling operation is activated, Cooling mode and a low humidity
operation point will be established. Fan speed level will be set to Automatic.
AUTOMATIC OFF
Automatic Off:enables the “[AC] Automatic Off” binary object, which lets
performing a temporary switch-off of the A/C unit by sending it a value of “1”
and a later switch-on by sending it a value of “0”. This object will be typically
linked to a window sensor or a similar event trigger. Automatic off will be also
active if the unit is previously in off state, so, the unit will not be able of being
on until this situation finishes.
During the temporary switch-off state, KLIC-DD3 will still monitor any control
orders being received (setpoint, fan speed, etc.), so they can be applied once
it leaves such state.
Automatic Off Object Polarity: sets the polarity of the above object: “0 =
Activate; 1 = Deactivate” o “0 = Deactivate; 1 = Activate”.
Automatic Off Delay: sets the time, in seconds, KLIC-DD3 waits before
switching the A/C machine off. Any switch-off order received during the
delay will abort the time count.
