1 INTRODUCTION

1.1 KLIC-DI V2

KLIC-DI v2 from Zennio is a gateway that enables full-duplex communication between the KNX home automation system and commercial and industrial range Daikin air- conditioning systems through the 2-wire connection provided by the latter.

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-DI v2 are:

Bidirectional control of Daikin A/C units of SKY commercial range or VRV

industrial range with variable refrigerant volume.

Control of the main functions of the commercial and industrial 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.

2 analogue-digital inputs, for the connection of temperature probes, motion

detectors or binary pushbuttons or switches.

10 customisable, multi-operation logic functions.

Up to five scenes.

Heartbeat or periodic “still-alive” notification.

1.2 INSTALLATION

KLIC-DI v2 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 KLICDI v2 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 (4): input ports for the stripped cables of external

elements such as switches, motion detectors, temperature probes, etc.

P1/P2 Communication (3): 2-wire communication cable that will connect

KLIC-DI v2 to the A/C unit. The other end of the cable, therefore, is intended to be connected to the P1/P2 connector in the PCB board of the internal unit.

Important: if intending to control the A/C unit both through its incorporated wired remote

control and through KLIC-DI v2, it must be taken into account the master-slave configuration assigned to both of them.

For detailed information about the technical features of KLIC-DI v2, as well as on security and installation procedures, please refer to the device Datasheet, bundled in the device packaging and also available at 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 restored, as well as the sending of certain objects to the KNX bus, 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 periodic “still-alive” notification.

Inputs.

Logic functions.

A/C gateway.

The latter entails all functions specific to KLIC-DI v2, 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

KLIC-DI v2

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

A/C Gateway [enabled]

: enables the “A/C Gateway” tab in the tree on the left.

For more information, see section 2.2.

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

the left, depending on whether the device will or will not be connected any external accessories. For more information, see section 2.3.

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

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

Heartbeat (Periodic Alive Notification): this parameter lets the integrator

incorporate a 1-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.

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 options.

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

[default/rest of 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 2.2.1 for further options.

“[AC] Fan: Percentage Control” and “[AC] Fan: Percentage Control

(Status)”: allow establishing desired fan speed or reading the current fan speed, respectively. See section 2.2.1.

Several error objects. See section 2.2.4.

2.2 A/C GATEWAY

2.2.1 CONFIGURATION

KLIC-DI v2 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-DI v2 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 16-32ºC range.

Fan speed: 2 or 3 levels, depending on the model of the A/C unit.

Control of flaps (or vanes) positioning: direct positioning or swing

movement of flaps, depending on the A/C unit.

Moreover, KLIC-DI v2 allows configuring several advanced functions:

Remote control configuration: which allows establishing the type of master-

slave control desired to KLIC-DI v2.

Indoor unit model: allows to select the indoor unit model between VRV and

Sky Air.

Operation mode management (only in VRV units): devices configured as a

master (note that this does not apply to devices configured as a slave) may also act as a master of mode or as a slave of mode in case multiple indoor units are connected to the same outdoor unit, which causes restrictions in the working modes of the indoor units depending on that selected in the outdoor unit. The configuration of such situation is detailed below.

Reference temperature: which allows supervising reference temperature that

it is taken into account by A/C unit for control temperature. This temperature can be the internal temperature of A/C unit or an external reference temperature, provided by a temperature probe.

KLIC-DI v2

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.

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 predefined climate control environments, to be

sent to the machine on the reception of scene orders from the KNX bus.

Operation time, provides in hours and/or seconds the A/C unit operating time.

These functionalities imply changes in the state of the A/C unit, which therefore notifies KLIC-DI v2 periodically about the current state. When KLIC-D v2 is notified about a change, it updates the status objects and sends them to the KNX bus. In addition, KLIC- DI v2 provides an error management function (see section 2.2.4), which allows sending messages to the KNX bus in case the A/C unit reports any errors.

ETS PARAMETRIZATION

The Configuration window under A/C Gateway provides the following parameters:

REMOTE CONTROL

Figure 5. A/C Gateway. Configuration.

Figure 6. A/C Gateway. Configuration. Remote control.

KLIC-DI v2

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

Remote control type [Master / Slave]: configures the control type of KLIC-DI

v2.

The master control type will correspond to the device which directly communicates with the machine. It will also be in charge of retransmitting the instructions to the slave control, if any. This configuration will still permit controlling the machine from the slave control.

This feature allows connecting to the same installation both the KLIC-DI v2 interface and the wired remote control of the A/C unit.

Important: in case of having KLIC-DI v2 and the wired remote control operating together, please, make sure that the control type of both devices is not the same (necessarily one of them must be master and the other slave).

Notes:

➢ Switching the wired control between the slave and master modes requires

interrupting its power supply in order to make the wired control re-initialise under the new mode.

➢ If the power supply of the wired control fails, it may be necessary to

disconnect and reconnect the bus voltage of the device after the power supply has been restored in order for the configuration between the wired control unit and the KLIC-DI v2 to be successful (especially if the KLIC-DI v2 has been configured as master and the wired control as slave).

INDOOR UNIT

Indoor unit model [VRV / Sky Air]: KLIC-DI v2 must be configured according

to the indoor unit model which will be controlled.
