1 INTRODUCTION
1.1 KLIC-DD V3
KLIC-DD v3 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. KLIC-DD v3 adds component
improvements and electrical safety over the previous KLIC-DD3.
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-DD v3 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.
Two analogue-digital inputs, for the connection of temperature probes,
motion detectors or binary pushbuttons or switches.
10 customisable, multi-operation logic functions.
Heartbeat or periodic “still-alive” notification.

1.2 INSTALLATION
Figure 1. Element scheme.
KLIC-DD v3 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-DD v3 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-DD v3 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-DD v3 to the A/C unit.
Important: Control the A/C unit both through its incorporated wired remote control and
through KLIC-DD v3 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 considered that orders sent from the
wireless control will have a higher priority than those sent through KLIC-DD v3. In
addition, certain parameterisations made in the device can be ignored.
For detailed information about the technical features of KLIC-DD v3, 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/C unit 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.

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.
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 2.2.1 for further information.
“[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 2.2.1 for further information.
“[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 2.2.1.
Several error objects. See section 2.2.4.

2.2 AC GATEWAY
2.2.1 CONFIGURATION
KLIC-DD v3 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-DD v3 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-DD v3 allows configuring several advanced functions:
Temperature measured by the AC unit: allows enabling an object which
provides the value of the internal temperature probe. The automatic sending
can be configured based on: a period of time, a change in value or a
combination of both.
Setpoint limits, to restrict the range for the temperature setpoint.
External reference temperature: which allows enabling an object to use an
external reference temperature, provided by a temperature probe.
Humidity: allows enabling six objects for the humidity control function. The
availability of humidity control depends on A/C unit model.
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.

Initial configuration, which allows establishing the desired initial parameters
for the state of the A/C unit after programming or restarting the device.
Scenes, which allows defining specific climate control presets, to be sent to
the machine on the reception of scene orders from the KNX bus.
Operating time: provides the A/C unit operating time in hours and/or seconds.
These functionalities imply changes in the state of the A/C unit, which therefore notifies
KLIC-DD v3 periodically about the current state. When KLIC-DD v3 is notified about a
change, it updates the status objects and sends them to the KNX bus. In addition, KLIC-
DD v3 provides an error management function (see section 2.2.4), which allows
sending messages to the KNX bus in case the A/Cunit reports any errors.
ETS PARAMETRIZATION
The “Configuration” tab under AC Gateway provides the following parameters:

OPERATION MODES
KLIC-DD v3 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.
“[AC] Mode (Status)”: 1-Byte object which allows knowing the A/C unit
operating mode status.

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 [disabled/enabled]: in addition to the “[AC] Mode” and “[AC]
Mode (Status)” one-byte objects, available by default, it is possible to
commute and to verify the current operation mode through the following onebit objects, which get enabled after activating this parameter:
“[AC] Simplified Mode”, which allows switching to the Cooling mode by
sending it a “0” and to the Heating mode by sending it a “1”.
“[AC] 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
Horizontal Flaps [disabled/enabled]: 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.
Vertical Flaps [disabled/enabled]: 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 following parameter:
Swing Object Polarity [0 = Swing On; 1 = Swing Off / 0 = Swing Off; 1 =
Swing On]: defines which value activates each swing.
Figure 6. AC Gateway. Configuration. Flaps.
FAN
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-DD v3 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:
