IRSC Zone DOCUMENT UPDATES Version Modifications Page(s) Changes in the application program: - New parameter added (“Zone update after reset”) to allow sending read requests for the states, modes and zone setpoints after bus failures. - Revision of texts and parameter names. -
Page 4: Introduction
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. In fact, IRSC... - Page 5 IRSC Zone 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. 1.- KNX Connector. 2.- Programming LED.

Page 8: Configuration
IRSC become particularised for the actual A/C unit to be controlled. The IRSC Zone application also allows selecting the number of the zones of the KNX installation that will be controlled by the same central A/C machine, which can be 1 – 8. -
Page 9: Ets Parametrization
To begin with the parameterization process of the IRSC controller it is necessary, once the data base of the product (IRSC Zone 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. - Page 10 If more zones are enabled (see section 3.2), the same seven objects will be available for the remaining zones, with a different value for “X” in each case. When entering the parameter edition of IRSC Zone for the first time, the following window will be shown: Figure 5.

Page 11: General
IRSC Zone As seen in Figure 5, the configuration screen is divided into the following main tabs: General: general configuration of the basic functionalities of the air conditioning system to be controlled. Mode: mode selection type permitted by the A/C machine. - Page 12 Zone update on start-up: permits activating or deactivating the sending of certain read requests to the bus after a download or a device reset order from ETS. These requests make it possible for IRSC Zone to assimilate the state of the environment (setpoints, temperatures, modes) at the moment of beginning to function.

Otherwise IRSC Zone may not be able to receive feedback from them. Consequently, instead of adopting the default values, IRSC-Zone will listen to...

A/C machine, which is made assuming that the A/C machine supports the selection of up to five working modes: Cool: intended for zone cooling. When IRSC Zone receives an order to commute to this mode, it sends the corresponding mode switch order to the... - Page 15 Zone will behave as under the “Cool” mode. Fan: destined to generate a simple air flow, typically at ambient temperature, from the air conditioning machine. When this mode begins, IRSC Zone keeps the air grilles of every enabled zone permanently open Dry: destined to generate a dry air flow, typically at ambient temperature, from the air conditioner machine, so that the humidity in the air is reduced.

Page 16: Fan
Note that, anyway, changing from one mode to another has two major consequences: first, the sending of the mode switch order to the machine; and second, switching IRSC Zone (when required) from one thermostat and grille control type to another. -

IRSC Zone Force medium fan under: sets the minimum number of grilles that must be open before it is permitted to commute from the medium fan speed to the maximum fan speed (object "A/C unit - Fan status" will reflect the current fan level;... - Page 18 IRSC Zone Figure 8. Temperature window Temperature range (only for Heat and Cool modes): it is possible to define limits for the setpoint temperature sent to the machine of each mode: Cool mode min. temperature: establishes the minimum general setpoint temperature, in ºC, allowed for the Cool mode.
- Page 19 Annex III. Practical example for a better comprehension. Note: it is necessary that the external KNX sensor periodically sends the measured temperature (the period should not be more than one hour). In case IRSC Zone does not receive any temperature through the Returned Temperature object within 60 minutes, it will stop taking into account this external temperature for the calculation process.

Related to device reboots, there is also the option to make IRSC Zone send read requests to the bus in order to get updated values of the objects that determine the initial state it should assume when it becomes functional.

Page 23: Annex I. Installation Scheme
With this input data, and according to the configuration parameterised in ETS, IRSC Zone will send orders, via IR commands, to the central A/C machine to acclimatise the installation zone by zone, as desired. -
Page 24: Annex Ii. Grille Control
While the zone is OFF, every mode change order and every setpoint change order will be ignored. Only once the zone is switched on again, IRSC Zone will resume the corresponding calculation and will send the order to open back the grille, if such order is considered to be required. -
Page 25: Thermostatic Control For Cooling
IRSC Zone THERMOSTATIC CONTROL FOR COOLING The thermostatic control for cooling, whose parameterization determines how IRSC Zone does its calculation when the zone is ON and the selected working mode is Auto, Cool, Fan or Dry, permits two algorithms for controlling the temperature (as the thermostatic control for heating also does): 2-Point Hysteresis control and PI (PWM modulation). -
Page 26: Thermostatic Control For Heating
IRSC Zone THERMOSTATIC CONTROL FOR HEATING In an exactly analogous manner, the thermostatic control for heating permits selecting between a 2-point with hysteresis control and a PI control with pulse width modulation. In this case, the flow diagram for the first one is as shown in Figure 14. -
Page 27: Annex Iii. Practical Example
Suppose a KNX installation as the one shown in the figure, where three zones (Z1, Z2 and Z3) are being acclimatised in the “Heat” mode by an IRSC Zone and an A/C unit. Also assume that zone Z3 has been switched off and that a maximum temperature of 24ºC has been parameterised for the Heat mode and that the “Temperature restriction”... - Page 28 28.5ºC. (value sent to the machine). From that moment, IRSC Zone will send the appropriate orders to the grilles in zones Z1 and Z2 (according to the parameterised algorithm for the thermostatic control for heating) so that the heat generated by the unit is conveniently directed to the zones, depending on their setpoint and reference temperatures..

IRSC Zone ANNEX IV. COMMUNICATION OBJECTS Column RESET shows the values of the communication objects after a reset, although this does not necessary imply that such values are sent to the bus. Cells marked as (*) in the 1 TIME and RESET columns show the possibility of sending such object to the bus (either as a write message or as a read request) when those events occur. - Page 30 IRSC Zone VALUES NUMBER SIZE FLAGS DATA TYPE (DPT) NAME FUNCTION RANGE 1ST TIME RESET 2 Bytes C T - W U [9.001] DPT_Value_Temp -273 - 670760 Zone 1 - Setpoint Setpoint Temperature 2 Bytes C T - W U [9.001] DPT_Value_Temp...
