1INTRODUCTION

1.1 KLIC-DD V3

KLIC-DD v3 fromZennio 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.

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 tab of the device.

ETS PARAMETERISATION

The “General” screen is shown in the first place, containing the following parameters:

Figure 3. General.

AC Gateway [enabled]

: entails all functions specific to KLIC-DD v3, relating

to communication with the A/C unit and management of the climate control

system. For more information, see section 2.2.

Inputs [disabled/enabled]: enables or disables the “Inputs” tab in the tree on

the left. For more information, see section 2.3.

Logic Functions [disabled/enabled]: enables or disables the “Logic Function”

tab in the tree on the left. For more information, see section 2.4.

Heartbeat (Periodic Alive Notification) [disabled/enabled]: 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).

The default values of each parameter will be highlighted in blue in this document, as follows: [default/rest

of options].

Figure 4. Heartbeat.

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.

KLIC-DD v3

http://www.zennio.com Technical Support: http://support.zennio.com

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 updatesthe 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:
