1. INTRODUCTION The KLIC-DI is an interface that allows a bidirectional communication between a KNX domotic system and the commercial series air-conditioning units. Due to this bidirectional communication, the air conditioning unit can be controlled in the same way that using an IR remote controller and the real status of the airconditioning unit is checked and sent to the KNX bus for its monitoring. Figure 1.1 KLIC-DI In case of using a wired remote control in the same communication bus of the unit, the KLIC-DI will communicate with this remote control acting one device as master control while the other device will act as slave control. It is important to verify that the KLIC-DI and the wired remote control are configured with different type of control. This way, the control acting as slave will update its status when the master orders it and will communicate its status changes when they are modified from the own slave control. Device Features: Small enclosure: 90 x 60 x 35 mm (2 DIN rail units) Designed to be installed inside distribution boxes or electrical mounting boxes. The device shall be installed outside the AC indoor unit. KLIC-DI provides bidirectional communication with industrial and commercial air conditioning units. ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 3
Provides control over the basic features of the unit together with control and error management, both of the own A/C unit codes, as well as the ones that may occur during communication. LED indicators allow monitoring of the bidirectional traffic flow. Integrated KNX Bus Coupling Unit. CE Compliant ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 4
2. INSTALLATION 2.1. KLIC-DI INSTALLATION The KLIC-DI installation is performed the same way that any other KNX device. We just need to connect the device to KNX bus through the specific KNX connector. On the other hand, this device is connected to the internal PCB of the A/C unit (P1/P2 connectors), using a 2-wire cable. If the wired remote control from is also used, it is necessary to make sure that the wired remote control is in mode slave if the KLIC-DI is configured as master control. And vice versa, if the KLIC-DI is configured as slave control, the wired remote control must be in master position. Once the device is provided with power supply from the bus, both, the physical address and the KLIC application program can be downloaded. This device does not need any external supply, since it just works with the power supply of KNX bus.

ELEMENTS DESCRIPTION Prog: To set the device programming mode. When initially pushed, after Powering, secure mode is set. Led: Luminous signal which indicates the state of the device. Besides including the programming red LED (typical in any KNX device), the KLIC-DI incorporates two more LEDs, blue and green ones, in order to inform about the bidirectional communication between KNX and the A/C unit, resulting very useful in the installation process. We can know the meaning watching the color: Red: programming LED. If it is ON indicates Programming mode. LED blinkling every 0,5s, the device is set in Secure Mode.

3. CONFIGURATION 3.1. BASIC CONTROL With KLIC-DI, the air conditioning unit can be monitored and controlled the same way it is done with the wired remote control provided with the air conditioning unit. By means of bus KNX, the following basic functionalities of the air conditioning system can be controlled: ON/OFF of the air conditioning unit. Setpoint Temperature. Between 16 and 32 ºC. Operating Mode: Auto, Heat, Dry, Fan and Cool. Fan Speed: 2 or 3 speed levels configuration. (Check out the available levels in the units) These functionalities have associated a machine status, which is periodically sent to KLIC-DI. When KLIC-DI receives a status different from the previous one from the machine, it updates the status of the corresponding parameter in the bus KNX. 3.2. ADVANCED FUNCTIONALITIES Besides the basic control over the air conditioning system, KLIC-DI offers other advanced functionalities that give an added value with regard to the wired remote control: Scenes Configuration: allows establishing a specific parameters combination for the air conditioning machine. Auto Switch Off: allows temporarily switching off the machine if a status change in the communication object associated to it, takes place. An example of this functionality could be the use of a window sensor, associated to the auto switch off, that allows switching off the machine if the window is opened. Temperature Limitation: Commercial units are limited in temperature (usually to the range 16-32 ºC. Please verify the range for a particular model in the corresponding A/C unit manual). This KLIC functionality allows configuring custom temperature ranges for the modes Heat and Cool by means of the ETS in such a way that the setpoint temperature ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 8
will remain in the range. In case of receiving a temperature command from the bus KNX with a value out of the configured limits, the temperature value sent to the machine will be the corresponding limit value. Indoor temperature and Reference temperature: Commercial A/C units have several temperature sensors for measuring the temperature in different internal points. The Indoor temperature is the measured internal value and it is used together with the Reference temperature for controlling the modes Auto-Cool and Auto-Heat of the air-conditioning machine. The Reference temperature is the real temperature in the room to acclimatize. It is necessary to communicate this parameter to the machine by means of the corresponding communication object and it is hardly recommended to link this communication object with a temperature sensor (installed in the room) which periodically updates the temperature value. The modes Auto-Heat and Auto-Cool can be controlled in three different ways by the A/C unit: 1. The unit receives the Reference temperature and, according to a preconfigured hysteresis by the installer, it establishes the corresponding auto mode. 2. The machine uses the Indoor temperature and, according to a preconfigured hysteresis by the installer, it establishes the corresponding auto mode. 3. The machine establishes the auto mode according to the average value of the Reference temperature and the Indoor temperature. The temperature value used by the machine in order to switch beetween the Modes Auto-Cool and Auto-Cool depends on the configuration established in the A/C unit installation. This value, in any of the previous cases is compared to the setpoint temperature in such a way that if the setpoint temperature is higher the Auto-Heat mode is established and if the setpoint temperature is lower than this value, the Auto-Cool is established. Take into account: It is hardly recommended to link the Reference temperature to a temperature sensor that periodically monitors the real temperature in the room because the way of switching between the different Auto modes might not be known and this fact can lead to a wrong functioning of the Auto mode. The Reference temperature has a default value equal to 25ºC. ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 9
Errors Management: this functionality allows the sending of messages to the bus informing about errors. Errors management handles the A/C unit error codes as well as any communication errors that may arise Besides informing about the apparition of possible errors it can be also configured the sending of the error type. In case of internal errors, the numerical code associated to the error type is shown in the following table: Error Number Type of Internal Error 1 Problems with the data reception (speed, parity, etc.) 2 Communication waiting time exceeded (Time-out) 3 Incorrect checksum 4 Incorrect response from the machine Regarding the numerical code associated to the external errors type, look up the manual of the installed air-conditioning system or the Annex II Correspondence Error Codes of the A/C units Initial Configuration: All machine status must have an initial value after installing the system or a power failure. With this purpose, it has been included in the KLIC the possibility of defining the initial status for the ON/OFF, temperature, fan and speed of the machine. These initial values can be sent both to the bus KNX and the air conditioning unit. Type of Control: Master/Slave It is important to take into account the type of control, master or slave, with which the KLIC-DI is going to be configured. The remote control master in the installation is in charge of the communication with the machine and it will retransmit the instructions and status between the machine and the slave remote control in case of having one. In spite of the master/salve configuration, all the functionalities can be set from both remote controls. ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 0
This functionality allows including both the KLIC-DI and the wired remote control in the installation and choosing the desired master/slave configuration whenever the KLIC-DI and the wired control are not configured with the same type of control. In case of having both controls configured as masters, the display of the wired remote control will show the error 88 and the error U5 will be sent to the bus. Take into account: When switching the type of control of the wired control between master and slave, it is necessary to remove the power supply from the wired control and connecting it again for rebooting the wired control in the suitable mode Important: The wired control BRC1E51A7 can only operate as master control. In case of using this model of wired control in the installation, it is necessary to configurate the KLIC-DI as slave control. Logical Functions KLIC-DI for commercial units includes a logical functions module similar to the one of other Zennio actuators. Up to 5 logical functions can be implemented and each function can be made of 4 operations. The user can read the Logial Functions section of the manual of any Zennio actuator (MAX6, QUATRO or Classic-Hybrid) in order to get more detailed information about them.

4. PARAMETERIZATION For starting to parameterize the device it is necessary to import the data base of the product KLIC-DI 1.6.vd2, once the ETS has been opened. Then the KLIC is added to the project where it is desired to include the device. Click with the right mouse button on the device and select Edit Parameters for starting with the configuration. In the following sections there is a detailed explanation about each of the different functionalities of the device in ETS. 4.1. DEFAULT CONFIGURATION This section shows the default configuration from which the device configuration starts. If the window Edit Parameters is opened for the first time, the KLIC General configuration by default will be found. Next figure shows the General window with the default values: Figure 4.1 Default General Configuration ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 2
As we can see in the previous figure all the advanced functionalities: scenes, temperature limitation, auto switch off, errors management and initial configuration are disabled by default. If the Mode and Fan are selected, it will be seen that both the Individual Modes and the Simplified Modes (Cool/Heat) are disabled by default while the Fan is configured for 2 different fan speeds and the step control is also disabled. Figure 4.2 Default Mode Configuration Figure 4.3 Default Fan Configuration In the next figure, the available communication objects by default are shown: they allow sending the ON/OFF to the Split, setpoint temperature, mode and fan speed (two speeds), as well as receiving the status of these variables from the Split. Figure 4.4 Default Communication Objects ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 3
4.2. GENERAL From the parameterization window General the advanced functionalities can be enabled: Scenes Temperature Limitation Auto OFF Errors Management Type of Control Indoor Temperature Sending Time Initial Configuration Logical Functions As we select the functionalities in the pull down lists, the access to the functionality configuration window will appear in the Menu at the left and the corresponding communication objects are enabled. This window also allows configuring the type of control for the remote control: Master/Slave And the Sending Time for the Indoor Temperature. This temperature is sent by the machine when the indoor temperature changes. In order to avoid an excessive sending of telegrams with this temperature, it has been implemented this parameter. This way, the indoor temperature will be sent every certain period of time specified with this parameter and only if the temperature has changed. 4.3. MODE As it has been previously seen in the default configuration, the specific Mode window allows the user select: Individual Modes When selecting the Individual Modes, two 1-bit communication objects will be enabled, one for controlling the mode and another one for receiving the status from the split, for each mode (Auto, Cool, Only Fan, Heat and Dry) besides the 1-byte communication objects for controlling and indicating the Mode that exist by default. ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 4
If the option Individual Modes is activated, the operating mode of the machine will be sent by means of the 1-bit Sending object associated to the mode. Moreover the Mode will be also sent to the bus KNX by means of both the 1-byte Mode objects for controlling and indicating the status of the corresponding mode. Simplified Modes The selection of the Simplified Modes will enable a 1-bit communication object with the same name that will allow choosing between Mode Cool (value 0) and Mode Heat (value 1). For this communication object, the corresponding status communication object does not exist. Figure 4.5 Mode 4.4. FAN SPEED In this window it can be selected the number of fan levels that the air conditioning unit has: 2 or 3 levels. The fan speed has two associated 1-byte communication objects that respectively controls and indicates the fan speed. The control object records the fan speed in percentage. For this reason this value will be interpolated in such a way that corresponds to the selected number of levels. The status object will show the fan speed according to the interpolated percentages. Two Levels of Fan Figure 2 Fan Speed If the fan speed configuration has 2 levels, the fan speed percentages will be interpolated in the following way: Initial Speed Interpolated Speed Level ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 5
Percentage Percentage 0-49% 25 % Minimum 50-100 % 100 % Maximum Three Levels of Fan On the other hand, with a fan speed configuration of 3 levels, the fan speed percentages will be interpolated according to the next table: Initial Speed Percentage Interpolated Speed Percentage Level 0-32% 25 % Minimum 33-65 % 50 % Medium 66-100% 100 % Maximum Besides configuring the number of levels the Fan window allows selecting the Step Control. Step Control The selection of Step Control enables a 1-bit object for increasing or decreasing the fan speed level: Value 1 : Increase Value 0 : Decrease The Step Control is not cyclical which means that if the fan speed is Minimum (0%), when the speed level is decreased, the speed will remain at this mode until the level is increased again. The same way, when the speed level is at 100%, the level will remain at this maximum until the speed is decreased. 4.5. SCENES A scene involves the synchronized sending of several commands to the air conditioning unit with the objective of generating a determined climate environment in the room. KLIC offers the possibility of configuring up to 4 scenes. ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 6
Figure 4.7 Scenes Once the Scenes are enabled in General, the option Scenes appears in the Menu. For each of the 4 scenes, the variables that can be configured are: Scene1-4: Figure 4.8 Scenes Configuration Example Scene Number: Scene number within the installation. ON/OFF: No change, switching ON or OFF the Split. Temperature: No change or temperature value between 16 C and 32 C. Mode: No change, auto, heat, dry, fan or cool. Fan: No change, minimum, medium o maximum. 4.6. TEMPERATURE LIMITATION ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 7
The air conditioning unit has defined upper and lower temperature limits that cannot be exceeded (the limits are usually 32ºC and 16ºC respectively). Nevertheless, KLIC offers the possibility of establishing new temperature limits if they are specified within the limits of the indoor unit The temperature limits can be personalized for the two modes with associated temperature: Cool and Heat. Figure 4.9 Temperature Limitation Once the limitation is enabled, when a value out of the range is sent from the bus KNX, the value that will be sent to the A/C unit will be the corresponding temperature limit and this new temperature value will be notified to the bus KNX. As a new functionality, it has been included a 1-bit communication object that will allow the user enabling (object to 1 ) or disabling (object to 0 ) these personalized temperatures restoring the unit default range. Take into account: When configuring in ETS the temperature limitation, this functionality is automatically enabled by default and the personalized ranges will control the unit performance when it switches on. 4.7. AUTOMATIC SWITCH OFF ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 8
When this option is enabled, the air conditioning unit will be temporarily switched off if a status change in the associated binary communication object is produced. This functionality has one configurable parameter: Delay for Auto-OFF: Number of seconds that KLIC-DI delays the air conditioning unit switching off. Figure 4.10 Auto-OFF 4.8. S MANAGEMENT The Errors Management window allows enabling the sending of messages to the bus indicating any error that may arise: internal errors of the communication between the KLIC-DI and the A/C unit or external errors, errors in the own A/C unit. It can be enabled the internal errors, the external errors or both: Internal Errors: Yes or no. External Errors: Yes or no. Every error type has associated two communication objects: the binary one indicates if an error has occurred and the 1-byte object that indicates the code identifying the error. Figure 3 Errors Management 4.9. INITIAL CONFIGURATION The initial configuration window allows configuring the initial machine status after the installation or a power failure. ZENNiO AVANCE Y TECNOLOGÍA www.zennio.com 1 9
The variables that can be initialized are the following: ON/OFF: Last, ON or OFF. Temperature: Last or custom. Mode: Last, auto, heat, dry, fan or cool. Fan: Last, auto, minimum, minimum-medium, medium, maximummedium or maximum. Moreover, it can be configured the Sending of status to the Bus or Split and when it must be carried out: Send Initial Configuration to?: Yes or no.
