1 INTRODUCTION
1.1 THE IRSC CONTROLLER
The IRSC controller from Zennio is aimed at controlling air conditioning systems
featuring infrared receivers (such as splits, ducted units with an integrated infrared
interface, etc) through the emulation of their IR remote control systems. Therefore,
IRSC combines the following functions into the same device:
Control of the main functionalities of A/C units (On/Off, temperature, mode,
fan speed, etc).
Compatibility with most air conditioning manufacturers (please refer to the
correspondence table, available at: http://www.zennio.com.
Device management through infrared codes:
Split units (application program: IRSC Plus).
A/V systems (application program: IRSC Open).
Ducted cooling/heating machines, with multiple zones to be acclimated
(application program: IRSC Zone).

1.2 INSTALLATION
The IRSC controller is connected to the KNX bus via the bus connecting terminals.

1.- KNX Connector.
2.- Programming LED.
3.- Programming Button.
4.- Aerial Connector.
5.- IR Emitter.
6.- Socket for the Aerial Connector.
Once the controller is provided with power from the KNX bus, both the physical
address and the associated application program may be downloaded.
In Figure 2, the connection scheme of IRSC is shown.
Figure 2. Element Diagram
The functionality of the main elements is described next.
Programming Button (3): a short press on this button sets the device into
the programming mode, making the associated LED (2) light in red. If this
button is held while plugging the device into the KNX bus, IRSC goes into
safe mode.
IR emitter (5): infrared flashing diode to send commands to the air
conditioning system. It must be placed in front of the air conditioning IR
receiver (see Figure 1.3).
Air connector Base (6): slot for the insertion of the aerial connector, through
which the IR commands are outputted from IRSC.
Figure 3 shows how to locate the IR emitter (5) in front of the climate system.

Once IRSC is connected and properly parameterised, it will be possible to control the
A/C unit from within the installation (for instance, from the InZennio Z38i or InZennio
Z41 touch panels), thus achieving an easier and more intuitive control.
Note: only one air conditioning unit may be controlled by each IRSC.
To obtain detailed information about the technical features of IRSC, as well as on
security and installation procedures, please refer to the device Datasheet, provided
with the original packaging of the device and also available at http://www.zennio.com.
1.3 THE IRSC PLUS APPLICATION PROGRAM
The IRSC Plus application program has been developed to control common air
conditioning systems via IR commands.
This application allows sending control orders to the A/C system through infrared
commands, with IRSC acting as a KNX-IR interface, as explained in Section 1.1.
The IR commands required to control the different air conditioning systems have been
already preset in the application. It is only necessary to check the IRSC Plus
correspondance table, available at http://www.zennio.com, in order to identify the
remote control model associated to the system.
Important note: there are two available versions of IRSC Plus: 6.12 and 8.0. Please,
check if the remote control wanted to be emulated with IRSC Plus is available for the
version in use. This information is available in the Correspondence Table for IRSC Plus
at www.zennio.com. In case it were needed to change the current version, just
configure and download the right version (please note that a version change might last
for several minutes).

2 CONFIGURATION
The IRSC Plus application program permits controlling air conditioning systems from
different manufacturers as if they were being controlled through the infrared remote
control of the machine.
A correspondence table is available at the Zennio homepage (http://www.zennio.com)
with the codes (from 0 to 255) corresponding to the different remote controls that can
be emulated. This number is the first parameter to be set in ETS, so that the orders
sent by IRSC become particularised for the actual A/C unit to be controlled.
Moreover, the following functionalities of the A/C system can be configured:
ON/OFF control of the A/C system.
Status Objects, which also work as acknowledgement objects for the orders
sent to the system.
Working Mode: the desired working mode (Automatic, Heat, Cool, Fan, Dry)
may be chosen through independent binary objects (one per mode) or
through a sole object (only one object for the mode selection). Moreover,
apart from these conventional controls, it is possible to enable a simplified
control, which only permits commuting from Heat to Cold and vice versa.
Fan Speed: step-controlled or through a precise control.
Possibility of enabling and configuring:
Up to 4 different scenes.
Timed ON/OFF switching.
Energy saving functions, such as window sensor and presence
detection.
All these options are explained in detail in section 3.

3 ETS PARAMETERISATION
To begin with the parameterisation process of the IRSC controller it is necessary, once
the data base of the product (IRSC Plus application program) has been imported to
ETS, to add the device to the project where desired. After that, one right-click on the
device will permit selecting "Edit parameters", in order to start the configuration.
In the following sections a detailed explanation can be found about the different
functionalities of IRSC Plus in ETS.
3.1 DEFAULT CONFIGURATION
This section shows the default configuration the device parameterisation starts from for
the first time.
Figure 4. IRSC Plus. Default Topology
The following communication objects are available by default:
ON/OFF, aimed to receive orders from the bus to switch on or off the A/C
unit.
Temperature, which will receive setpoint temperatures (in ºC) to be sent to
the machine. Moreover, this object can work as a status object, as the “R”
(read) flag is active by default.
Fan [1 byte], aimed to receive orders from the bus to switch the A/C machine
from one fan speed to another (automatic, minimum, medium or maximum,
depending on the range the received value belongs to).
