    1CONFIGURATION OF A VENTILATION SYSTEM BY COMPONENT SELECTIONTECHNICAL FIELDThe present invention relates to an air ventilation system for providing fresh air to abuilding, e.g. a Heating, Ventilation and Air-Conditioning (HVAC) system. Theinvention is in particular directed to the feature of configuring components in a controlsystem for the air ventilation system.
    BACKGROUNDln offices and other larger buildings, there is often a need to be able to control theindoor climate. ln order to provide an efficient control for a building is it today oftenprovided with a Heating, Ventilating and Air Conditioning system which generally isreferred to as a HVAC system. This system is desired to be able to control the indoorclimate according to specific requirements for different parts or individual rooms inthe building. For example, the ventilation and amount of fresh air could be set independence of the presence of individuals in a room and the heating or coolingdemand according to a set, desired temperature. The HVAC system generallycomprises a ducting system connected to an air handling unit having fans for takingin fresh air and admitting outlet air out of the building while heat exchanging the inlet-and outlet air streams. The ducting system is further provided with a multitude ofcomponents such as air flow controllers, induction units and their associated heatexchangers and air diffusers for admitting air into the respective locations and thereare also different kind of sensors and user interfaces for setting a desired roomconditions connected to the HVAC system. Components for influencing the flow rateand the quality of the air, e.g. temperature and humidity, as well as sensors forsensing properties of the air and user interfaces or displays are connected to acontrol system in order to control the HVAC system to reach a desired roomcondition if possible.ln many cases are there a large number of components as described aboveincorporated in the control systems and these components are located in manydifferent parts and rooms of the building. ln general is therefore each componentcontrolled individually, or possibly a group of components in a certain part of thebuilding controlled together sometimes, since there may be different actual anddesired conditions for many different parts where the indoor climate shall becontrolled. ln order to be able to perform this control accurately for the different partsof the HVAC system by a central control unit is there a need to identify the differentcomponents by the control unit. ln general is each component which is used for thecontrol of the HVAC system provided with a unique component ID. However, thiscomponent ID is not of much use for control of the HVAC system knows where in theHVAC system each component is located. The central control unit needs thus toproperly associate the unique component ID of each component with its physicallocation in order to control the components of the HVAC system adequately to reachthe desired set conditions for the different parts of the building. There is thus a needto assign a system location ID to each component in the HVAC system such that itslocation will be known by the central control unit. The system location ID may forexample be defined in a system description of the air ventilation system including aconfiguration list with system location IDs for components. In general, there is aspecific system location ID for each component to be connected to the central controlunit even though it could be possible to use the same system location ID for a groupof components which shall be controlled in the same way always. As previouslymentioned, HVAC systems as described above are in use today for large buildingsand one example of such a system is disclosed in US 2015/269503.
    The work with setting up the network configuration and assigning each component ata specific location with its system location ID has earlier predominantly been donemanually. One way of doing this is to mount a specific individual component, knowingits component ID, at a predefined location having a system location ID wherein thecontrol system is configured to assign this system location ID to the component ID ofthe specific component. Another way has been to place the component at its locationand manually reading component ID which thereafter is input in the control system tobe associated with the system location ID representing the actual position where thecomponent is mounted. Both these systems are vulnerable for mistakes by aprogrammer or operator. ln the first case may the component be mounted at thewrong location and in the second case may the unique identification be misread orassigned to another physical location in the HVAC system if its unique ID is enteredto a faulty position in the control system. There is thus a need for a system whichmay reduce the probability for mistakes made in the configuration of the controlsystem for a HVAC system.
    DISCLOSURE OF THE INVENTIONThe invention relates to a method for configuring components forming part of acontrol system for an air ventilation system and an air ventilation system adapted tobe configured according to the method.
    The systems described above could be improved by using a more automatizedprocess for configuring the control system and adapting these systems to assure thatthe components are configured properly in the control system. An automatizedprocedure is for example disclosed in US 2015/120063 which describes a way toconfigure a HVAC system having individually controlled components, each one with aunique ID. However, the process includes the need to bring each component in thesystem to be assigned with a unique ID in close proximity to a main system controllerto be done before mounting. This could be an obstacle if the components are heavyand/or bulky and they need to be carried to the main system controller. ln addition,the components could not be mounted if the main system controller is not available.Hence, the present invention describes a possibility for an automatized processallowing the components to be mounted at their location in the ventilation systembefore they will be configured in the control system.
    According to an embodiment of the invention are all the components which shall beindividually recognized in the control system provided with a component ID. This mayhave been provided already at the manufacturing process or at a later stage, it mayeven be done when the components are mounted. However, the important feature isthat the components to be used in the control system have been assigned a uniquecomponent ID before they may be configured in the control system. The uniquecomponent ID should be marked on the product such that it may be readautomatically and to be selectively read for each component by an identifier. Themarking may be any kind of code or text that may be read from a distance with anidentifier. ln general is this marking of the product some kind of visible label, e.g. abar code, QR-code or even text made readable for an identifier from a distance.Whatever marking system that is used is the system intended to function such that itis only the product to which the reader is directed which possibly may be read by thereader, i.e. there should not be a possibility that the selected component could bemistaken for any other component.ln general, the word “component” has in this disclosure been reserved for an elementforming part of the air ventilation system and is intended to be connected to thecontrol system via a transmitter and/or receiver. The communication may be by wireor wireless. ln most cases are the components adapted to both transmit and receivesignals and they may thus in general be provided with a transceiver for this purpose.The components may be elements which are used to control the ventilation and airflow, e.g. dampers in the air ventilation ducting systems, fans for providing an air flowin the air ventilation system, heat exchangers for controlling the temperature of theair flow or air diffusers in the rooms or spaces to be ventilated. Other kind ofcomponents which may form part of the control system are different kind of sensors,e.g. humidity sensors, temperature sensors, carbon dioxide sensors or occupancydetectors, or user interfaces where it is possible to require certain features, e.g. athermostat for setting a desired temperature or a control button for requesting anincreased ventilation for a specific time. Hence, the control system may include anycomponent which may provide relevant information concerning present and desiredconditions for the comfort and air quality in a room or space as well as adjustablecontrol devices which influence the quality and quantity of air to be ventilated in acertain room or part of a building.
    The components to be configured in the control system may have been provided withsome kind of signal system. The signal system could for example be used torecognize that the component is selected, e.g. identifying the component by itscomponent ID, or for indicating the status of a component. This signal system mayfor example be a light indicator, e.g. a LED-light, a sound indicator creating a “Blip”-sound or any kind of recognizing feature which responds when the component isselected. ln this case is the important thing with the indicator that it is physicallyconnected to a specific component and may be easily recognized and used toidentify when the selected component is located.ln order to identify a specific component or a group of components is an identifierused. The identifier is of course designed to function and interact with thecomponents and may thus be designed to function in different ways depending onhow the component ID is marked onto or comprised in the components. The identifiercould for example be an IR-reader for reading a bar code or QR-code. To be noted,an identifier need not to be a single unit but could comprise a set of units forming anidentifier, e.g. one unit for decoding or reading the identity and another unit fordisplaying the selected component or components. Hence, an identifier as describedherein always includes the feature of being able to identify one component. lngeneral, there is also a confirmation on a selected component itself revealing itsstatus as being selected by its signal system, e.g. a blinking light. However, thisfeature is not necessary when there is appositive identification of one singlecomponent, e.g. using a bar code- or QR-reader, even though it may be a usefulfeature to have a response from the component that it has been selected. ln anycase, there should preferably be some kind of recognition that the component hasbeen selected and its component ID read. The selected component could forexample be displayed in the identifier and/or there could be a sound indicating thatthe component has been selected. This recognition on the identifier could of coursebe performed together with an indication on the product itself.
    Above has it been explained the function of some of the devices used in the systemas well as defining some of the terms which will be used in the method explainedbelow for configuring components in an air treatment system such as a Heating andVentilating Air-Conditioning (HVAC) system. The components forms part of a controlsystem for the air ventilation system and the control system comprises one or severalcomponents selected from the groups of flow control components such as fans,dampers and air inlet diffusers, sensor components which for example sensetemperature, humidity, carbon dioxide content or input control components such asuser interfaces or other control buttons or levers for setting a desired condition. Alsodisplays for indicating conditions could be included as a component in the airventilation control system as well as heat exchangers. The components areconnected to a central control unit when the components are configured and the airtreatment system is in use such that the central control unit may control the airventilation system and the quantity and quality of the ventilated air. Depending ontheir functions are the components provided with a transmitter and/or receiver forsending an input signal to the central control system to be used for informationpurposes or computing a control output command by the control system and/orreceiving an output signal from the central control system in order to send informationor control the component associated with the respective transmitter and/or receiver.ln general, the components are provided with a transceiver allowing a component tosend and receive information signals. Each of the components is further providedwith an Electronic Control Unit (ECU). There could also be present, but notnecessarily, an indicator and which could be programmed by the ECU to activate theindicator at appropriate occasions, e.g. when there is an error in the unit, when thecomponent is active or the intensity of the components activity. The ECU could in thiscase also be programmed to indicate when the component has been selected by anidentifier sending an identification signal selecting the component which may forexample be used during configuration of the central control system.The configuration comprises the steps of:I. Preparation, in which the components and the identifier are prepared to beable to configure the setup of the system,II. Selection procedure, in which a component is identified by its identity andlocation in the system, andIII. Configuration, in which the component is configured in the control systemso as to be able to be identified concerning its location and identity by thecentral control unitThese steps are intended to be performed in the order described above, at least tosuch an extent that the first step should be finished before the second step is finishedand the second step will be finished before the third step is finished for at least onecomponent. Each of these steps will now be further explained in detail below.The first step, preparation (I), has been divided into two different preparatoryprocedures, step a and step b, which may be performed in any order. ln one of thesesteps, referred to as step a, is one or several of the components which have beendescribed above located at its intended physical location or position in the airventilation system. Preferably is the component mounted as it should be incorporatedin the system when the system is working but this is not necessary, it may just aswell be merely placed at its location or provisionally mounted in order to becompletely mounted in the system at a later stage. A component which is located atan intended position in the system has been assigned a unique component ID beforeit was located at its intended position or it may be assigned a unique component IDafter it has been located at its intended position. However, in many cases acomponent is assigned a unique component ID already when it is manufactured atthe factory. The unique component ID should be marked on the product such that itmay be read automatically and to be selectively read for each component by anidentifier. Whatever marking system that is used is the system intended to functionsuch that it is only the product to which the reader is directed which possibly may beread by the reader, i.e. there should not be a possibility that the selected componentcould be mistaken for any other component.ln another step, referred to as step b, is the identifier provided with a systemdescription of the air ventilation system. This system description is a representationof the air ventilation system which may be more or less detailed, e.g. a 3-D imagerevealing essentially the complete air ventilation system, a simpler plan view merelyindicating the more relevant features of the air ventilation system or configurationtree. However, the system description shall at least comprise information concerninghow the components forming part of the control system are referred to by the centralcontrol system and where in the air ventilation system they are located. Hence, thesystem description should include a configuration list with system location lDs forcomponents in the air treatment systems which will be connected to the centralcontrol system. By configuration list is herein intended to include any kind offormalized information providing information of system location lDs which may beused when assigned to a component to be readily recognized by the central controlsystem to identify the kind of component and where it is located in the air ventilationsystem. Hence, by performing step a and b will the air ventilation system be ready forthe next main step in the configuration method, the selection procedure (ll).
    The selection procedure (ll) has been divided into two partial steps, step c and d,which will be performed as described below.ln step c is the physical location of the desired component to be configured in the airventilation system identified. ln general, this means the person who is configuring thesystem will walk to be in the vicinity of the desired component to be configured. Theidentifier should be brought to this location and located to be in reach for wirelesscommunication with the desired component. Hence, the identifier may nowcommunicate with the desired component. The person who is at the location shouldalso be aware of which of the components in the system he is selecting as thedesired product. lt shall be noted that step c could be performed before step a and/orb. however it is therefore described that the preparation (I) not necessariy must becompleted before the selection procedure (ll) starts even if it is in genral not anefficient way of working.ln the next step, step d, is the identifier used for sending an identifying signal in orderto identify the desired component. The signal sent from the identifier may thus reacha desired component via wireless communication or signaling. The identifying signalis an automatic reading of the marking on the component comprising informationconcerning the component ID. This identification should be performed such that thesignal will positively recognize only the desired component. There is preferably anindication in the identifier, e.g. on a display, that the component has been identified tobe used and be paired in the next configuration step (lll).ln the configuration step (lll) is a pairing event performed, this step is also referred toas step e. ln the pairing event is the desired component, having its uniquecomponent ID, paired with the system location ID. The pairing event could beperformed automatically when the component ID is recognized but preferably is theresome control feature or action initiated by the operator, e.g. could the system locationID be displayed in the identifier. ln addition, if the feature is available, could thedesired component indicate it is in a selected state. By pairing these lDs, thecomponent ID and system location ID, is it meant that these lDs are connected to berecognized by each other. For example, the pairing event may include the feature ofassigning the location ID to the component such that the component may berecognized by the system location ID as well as by its original component ID. Anotherway to perform this could be to send information to the central control unit torecognize the component ID for the desired component which could be used whenthe central control unit is receiving or sending information to the component locatedat the place which is assigned to the selected system location ID used in this pairingevent. Or as still an alternative, the paired system location ID and component ID maybe stored in a separate memory and be used as a look up table or translator whensending information from the central control system to the desired component.Hence, there are many ways of performing the pairing event such that the desiredcomponent may be recognized by the system location ID by the central control unit.
    BRIEF DESCRIPTION OF THE DRAWINGSThe present invention will now be described more in detail with reference to theappended drawings, where:Figure 1 discloses an overview of a ventilation system for a room in a buildingFigure 2 discloses a component of the systemFigure 3 discloses a system description of the air ventilation system with systemlocation lDs (sl-lDs)Figure 4 discloses a system description of the air ventilation system with systemlocation lDs (sl-lDs) and component lDs (clDs) for components mountedin the system in un unpaired stateFigure 5 discloses a system description of the air ventilation system with systemlocation lDs (sl-lDs) and component lDs (clDs) for components mountedin the system in a paired stateFigure6 discloses a block diagram of a method for pairing and configuring acontrol system for an air ventilation systemDETAILED DESCRIPTIONln figure 1 is disclosed a ventilation system 100 in a room 101 in a building (notshown). The ventilation system 100 comprises a multitude of components (1a-1f)which are connected to a ducting system 102 and forms part of a ventilation controlsystem. Among the components (1a-1f) are there flow control components (1a-1d)such as four air diffusers (1a) for admitting air into the room 101, exhaust air intake(1b) for ventilating air out of the room 101, a main ventilation unit (1c) which providesfor heat exchange of fresh air intake and exhaust air and induce a flow in the ductingsystem 102 and 2 dampers (1d) for controlling the flow in the ducting system 102.The main ventilation unit 1c is connected to a fresh air intake 103 and an exhaust airoutlet 104 which are connected to the ducting system 102.There are also present anumber of sensor components (1e - 1g) in the room 101 such as a carbon dioxidesensor (1e) also referred to as C02 sensor, a humidity sensor or RH sensor (1f)wherein RH means Relative Humidity and a temperature sensor (1g). There is alsopresent a user interface (1 h) which may be a control input device for setting a desiredtemperature or for demanding increased ventilation for a predefined time limit. Theuser interface (1g) could also comprise a display for information concerning presentconditions in the room 101. These components (1a - 1h) only serve as a fewexamples of different components which may be present in the ventilation system. lngeneral, the word “component” has been reserved in this description for deviceswhich forms part of a control system for the ventilation system, i.e. devices whichcontrol the flow and/or the quality of the ventilation air as well as sensors forindicating relevant properties of the air or user inputs for setting a desired values forair properties.
    When the ventilation system 100 is functioning are the components (1a-1g) whichforms part of the control system connected to a central control unit (CCU) 105 whichhas been located close to the main ventilation unit 1c. ln general, the main ventilationunit 1c and is located in another room and is adapted to provide for ventilation inseveral rooms or even one or several buildings. However, the main ventilation unit 1chas been located in the room 101 in this example for serving the purpose ofillustrating and understand in a better way how the ventilation system 100 works. lnthis example has the central control unit (CCU) 105 been located close to the mainventilation unit. Such a CCU 105 may be designed to control one or more mainventilation units and components associated to the ventilation systems. Hence, thereis in general neither present a CCU 105 in every room and the CCU 105 is includedfor better illustrating the control system of the air ventilation system.ln figure 2 is disclosed a general description for features which are common for allthe components (1a - 1g) which are disclosed in figure 1 and are intended to formpart of a control system for such an air ventilation system 100 as exemplified in figure1. The component is exemplified by an air diffuser 1a but could have been any of theother components disclosed in figure 1 or any other component which is intended toform part of a control system for such a ventilation system 100 as disclosed in figure1.
    The air diffuser 1a comprises a transceiver 2 which may be used for communicatingwith the CCU 105 (se figure 1). The transceiver 2 is adapted to be able to transmitand receive signals and could be designed to be wireless or connected by wires tothe CCU 105. The transceiver is further connected to an Electronic Control Unit(ECU) 4 which is programmed to control the air diffuser 1a and to compute controlsignals and information to be transmitted and received by the transceiver 2. Thetransceiver 1a could be substituted for a transmitter or receiver if the component onlyneeds to transmit or receive a signal.
    The air diffuser 1a has further been provided with a unique component ID referred toas clD. ln general may this this unique clD be represented by a long row of numberand letters, e.g. 00:20.8C:00:08:17:54:6D. ln many cases is this unique clD inaddition to be component specific also giving information about product category andproduct kind. The products clD may be comprised visually, e.g. by marking theproduct with a readable plain text as above. The clD could also be programmed into11the ECU 4 or comprised in a RFID. In addition, the product identity could be markedon the product by code intended to be read by an identifier. ln this figure a label 5has been marked on the product which is intended to be able to read by the identifier.The label 5 could for example be a bar code or QR code. The information comprisedin this visible code should at least provide the clD for the component. The plain textas disclosed above could also be used but such text is in general less reliable to beread from a distance. The unique clD is generally provided at the factory but mayalso be assigned later on if desired.ln figure 2 has the component 1a been assigned a component ID (clD) which hasbeen shortened compared to what is normally used in order to better illustrate howsuch an ID may be built up to serve different purposes. The component 1a has beenassigned the clD “FC:AD:0001” which is written beside the component. This clD isintended to provide the information that the component belongs to main group flowcontrollers (first two digits FC), further to subgroup air diffusers (third and fourth digitsAD) and the last four digits (0001) will respond to a unique identity number. Hence,the clD as described herein serves both the purpose of identifying product categoryand kind as well as being a unique identification of the component. This informationis thus comprised in the label 5 which is marked on the product.
    As is obvious, the code marked on the label 5 will differ for each component 1a- 1g,this is of course valid for the four individual air diffusers 1a (se fig 1) also if thesystem described herein is used. Also the ECUs 4 will most probably differ for eachcomponent, e.g. by having the unique component ID stored in its memory.
    A list of the component IDs in figure 1 could be the following:First air diffuser (1a): FC:AD:0001Second air diffuser (1 a): FC:AD:0002Third air diffuser (1a): FC:AD:0003Fourth air diffuser (1a): FC:AD:0004Exhaust Air intake (1 b): FC:EA:0001Main unit (1c): FC:MU:0001First damper (1d): FC:DU:0001Second damper (1d): FC:DU:0002C02 sensor (1e): SU:CO:0001Humidity sensor (1f): SU:RH:0001Temp. sensor (1g): SU:TE:0001User interface (1h): Cl:Ul:000112ln this list are thus the first two digits of flow control components (FC), sensor units(SU) respectively control input devices (Cl) the same to identify the groups ofcomponents while the third and fourth digits are dividing the groups into subgroupsdepending on the product categories and the last four digits will give each componenta unique component ID (clD).ln order to get the air ventilation system in figure 1 to work properly the controlsystem must be configured. The components 1a-h needs be mounted to the airventilation system 100 at appropriate locations and connected to the central controlunit 105. The central control unit needs to know which components that have beenmonted at which location. ln some cases, e.g. when a group a components areintended to be controlled in exactly the same way, may it not be necessary to knowexactly which component that has been assigned an exact location. As an example,if all the four air diffusers 1a located in the room 101 in figure 1 shall be controlled inexactly the same way may it be enough to group these four units together and usethe same identity when sending control commands from the CCU 105 to the airdiffusers 1a. However, the CCU 105 must be able to recognize the four componentslocated at these places.
    Figure 2b only differs from figure 2a in that the component 1a has been provided withan indicator 3. The indicator could be a light source such as LED light or diode. Theindicator is intended to indicate a status of the component 1a and could be used inthe configuration of the control system by for example indicating a component isselected, a pairing event is occurring or that the component has been configured inthe air ventilation system. However, this feature is optional for the system and theconfiguration method described herein.ln order to be able to control the air ventilation system has the location of eachcomponent which is included in the air ventilation system been provided with asystem location ID according to a system description. This system description maydefine different groups or zones. For example, room 101 in figure 1 could be definedby being located in building 3 of a complex of buildings. The building may thereafterbe divided in sections, e.g. could different floors be different sections. The room 101could be located in section A corresponding to a floor. The section may thereafter bedivided into different rooms and the room 101 in figure 1 could be assigned to beroom 3. These definitions could for example be used such that all components in this13room will be assigned a system location ID (sl-ID) which starts with 3A4 indicatingbuilding, zone respectively room.ln figure 3, which is based on the very same figure as is presented in figure 1, isdisclosed a system description in which all the components are marked with asystem location ID (sl-ID). A system description is thus a representation of the airventilation system 1 disclosed in figure 1. At the top of the system description iswritten “room 3A4”. This means these three characters are intended to be the 3 firstdigits for each system location ID for the components represented in figure 3 and thelast digits are written at each represented component. As can be seen in figure 3 allrepresented components have been provided with a unique sl-ID. This is essentiallynecessary for all components with the exception for the air diffusers which couldhave been assigned the same sl-ID if they are intended to be controlled in the sameway.ln order to configure the air ventilation control system is there a need to connect thesl-ID for each represented component in figure 3 with the unique component ID.Hence, the central control unit (CCU) 104 needs to be able to recognize therespective ECUs 4 for each component 1a-g in order to know which component 1a-gwhich the CCU is communicating with via their transceiver 2.ln order to connect these lDs, clD and sl-ID, are the physical components located atits intended positions, preferably mounted to the air ventilation system 1 as theyshould be connected. ln figure 4 this is illustrated by also having appointed thecomponent ID besides each component. However, there has been provided aninequality sign between the different identities since there is no connection orrecognition between the identities at this moment.ln order to make the component mounted to the air ventilation system, having itscomponent ID, to be able to be recognized by the central control unit 105, must thesetwo identities identify each other. This could be made by a pairing event. Theoperator is selecting which component to be identified from the system description,i.e. selecting a defined system location ID and position himself where the componentis mounted, at a location where the component ID may be identified by using theidentifier, e.g. by optical reading of the label 5 of a component comprising informationconcerning the component ID. The correct system location ID is selected from a listof components in the identifier. Thereafter is the identifier used to identify thecomponent ID of the component and the component ID read from the label 5 may be14connected, i.e. paired, with the system location ID. The pairing may result in that thecomponent will be provided with the identification such that it recognizes a signalfrom the CCU 104 directed to the paired system location ID, the component ID couldbe stored in the CCU such that it will send signals addressed to the component IDand/or store the paired connection in a separate translator which is used whentransferring information between the CCU 104 and ECU 4 of the paired component.The specific way this pairing is stored is of less importance for the system describedherein. When all units have been paired is thus the control system for the airventilation system configured and there is possible for the components at eachlocation to be readily controlled by the CCU. Hence, in figure 5 is the systemdisclosed after the pairing action has been completed for all components and this isthus described by marking the connection between the identities with a sign ofequality.ln figure 6 is disclosed a diagram concerning the configuration procedure.
    The configuration is divided into three main procedures to be performed: Preparation(I), selection procedure (ll) and configuration (lll).ln the preparation (I) are there two steps which are performed, step a which isrepresented by the first block and comprises the feature of locating the components1a-h in the air ventilation system, and step b which is to prepare the identifier byloading a configuration list of the air ventilation system comprising system location IDfor the components 1a-h in the air ventilation system 101.ln step a are thus the components located in the system at its desired locations,preferably also mounted so as to function as desired when the air ventilation system1 is working. ln general is it desired to mount all components, or at least allcomponents in a zone or area, before the configuration of the control system isstarted but the configuration of a component could also be made if only one singlecomponent is located at its location in the system. The components are in generalalready provided with a unique component ID when manufactured. Otherwise thismay be performed at any time before the system shall be configured, e.g. whenmounting. lf all components are mounted to the air ventilation system, and thecomponents have been provided with a component ID, and no configuration of anycomponent has been made should the air ventilation system be in the state asdisclosed in figure 4, i.e. all components at their right location but no connection oridentity between the system specific system location ID and the component specificcomponent ID.ln step b is the identifier provided with a system description of the air ventilationsystem. This system description could for example be the plan view in figure 3wherein the location of each component is shown and has been provided with asystem location ID. This plan view, or at least a configuration list with system locationlDs for components of the plan view, may thus be loaded into the identifier. As isobvious, it may also be possible to only load a few of all components into theidentifier if that should be desired for some reason as long as it comprises the systemlocation ID of the component or components to be configured. Hence, thecomponents for which step a and step b has been made may now be selected in theselection procedure (ll) to be configured.ln the selection procedure (ll) are there two partial steps, step c and d, wherein adesired component is selected in step c and its component ID is identified in step d.ln step c is the identifier brought to be at a location wherefrom it may identify thedesired component. ln the case of identifying the component by an IR code readerreading a label with a code on the component should thus the code reader be at asuitable distance for being able to read the label. The identifier is thus ready to beused for identification of the clD of the desired component. The desired component isselected from the configuration list in the identifier, either directly from arepresentation of a system description comprised in the identifier or by selecting asystem location ID from a configuration list corresponding to the system location ID ina plan view.ln the next step, step d, is the identifier used for sending an identifying signal in orderto identify the desired component. The identifying signal is an automatic reading ofthe marking on the component comprising information concerning the component ID,e.g. an IR-signal for reading a coded label. ln this way the component ID may bepositively recognized from a distance. There is preferably an indication in theidentifier, e.g. on a display, that the component has been identified to be used and bepaired in the next configuration procedure (lll). ln addition may there be an indicationon the component itself if it has been provided with an indicator controlled to confirmidentification when being identified by the identifier.ln the configuration procedure, comprising step e, is the component configured in thecontrol system so as to be able to be identified concerning its location and identity by16the central control unit. This may be achieved by a pairing event in which the desiredcomponent, having its unique component ID, is paired with the system location ID.The pairing event could be performed automatically when the component ID isrecognized but preferably is there some control feature or action initiated by theoperator, e.g. could the system location ID be displayed in the identifier. ln addition, ifavailable the feature is available, could the desired component indicate it is in aselected state. By pairing these lDs, the component ID and system location ID, theselDs may be connected to be recognized by each other and the component may becontrolled by the central control unit.
    The pairing event may be indicated in the identifier and/or on the component, e.g. bya flashing light while the component is pairing and then allow a light on the product tolight or marking the location system ID in the identifier as being paired when thecomponent is paired.
    The identifier which is used for the identification and pairing of the components couldbe designed to either directly transfer the information to the central control unit orstoring a number of paired components to be transferred as batch. For example, itmay be desired to complete pairing of all components in a room before the pairing ofthe components actually is transmitted to the central control unit, or other memory,such that the central control unit may identify a component. The components could, ifthey are provided with a light indicator, be controlled to be off when unpaired, to beturned on with a fast blinking light when selected and during its pairing event whereafter they turn to blink with a lower frequency when they are paired but yet not havebeen accessible by the central control unit where after the light is turned onconstantly when the component is configured to be recognized in the air ventilationcontrol system by the central control unit.
    The status of the system in figure 5 thus corresponds to the state when all productshave been paired and configured in the system.
