Description

DESCRIPTION
TECHNICAL FIELD
[0001] The present invention relates to an air ventilation system for providing fresh air to a building, e.g. a Heating, Ventilation and Air-Conditioning (HVAC) system. The invention is in particular directed to the feature of configuring components in a control system for the air ventilation system.
BACKGROUND
[0002] In offices and other larger buildings, there is often a need to be able to control the indoor climate. In order to provide an efficient control for a building is it today often provided with a Heating, Ventilating and Air Conditioning system which is generally referred to as a HVAC system. This system is desired to be able to control the indoor climate according to specific requirements for different parts or individual rooms in the building. For example, the ventilation and amount of fresh air could be set in dependence of the presence of individuals in a room and the heating or cooling demand according to a set, desired temperature. The HVAC system generally comprises a ducting system connected to an air handling unit having fans for taking in 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 of components such as air flow controllers, induction units and their associated heat exchangers and air diffusers for admitting air into the respective locations and there are also different kind of sensors and user interfaces for setting a desired room conditions connected to the HVAC system. Components for influencing the flow rate and the quality of the air, e.g. temperature and humidity, as well as sensors for sensing properties of the air and user interfaces or displays are connected to a control system in order to control the HVAC system to reach a desired room condition if possible.
[0003] In many cases are there a large number of components as described above incorporated in the control systems and these components are located in many different parts and rooms of the building. In general is therefore each component controlled individually, or possibly a group of components in a certain part of the building controlled together sometimes, since there may be different actual and desired conditions for many different parts where the indoor climate shall be controlled. In order to be able to perform this control accurately for the different parts of the HVAC system by a central control unit is there a need to identify the different components by the control unit. In general is each component which is used for the control of the HVAC system provided with a unique component ID. However, this component ID is not of much use for control of the HVAC system unless it is known where in the HVAC system each component is located. The central control unit needs thus to properly associate the unique component ID of each component with its physical location in order to control the components of the HVAC system adequately to reach the desired set conditions for the different parts of the building. There is thus a need to assign a system location ID to each component in the HVAC system such that its location will be known by the central control unit. The system location ID may for example be defined in a system description of the air ventilation system including a configuration list with system location IDs for components. In general, there is a specific system location ID for each component to be connected to the central control unit even though it could be possible to use the same system location ID for a group of components which shall be controlled in the same way always. As previously mentioned, HVAC systems as described above are in use today for large buildings and one example of such a system is disclosed in US 2015/269503. In recent years, there has been an increased desire to remotely access such control systems, e.g. by using a smartphone, and the systems may have an interface for control by SMS as disclosed in for example US 2016 I 040 900 and US 2014 I 151 456, [0004] The work with setting up the network configuration and assigning each component at a specific location with its system location ID has earlier predominantly been done manually. One way of doing this is to mount a specific individual component, knowing its component ID, at a predefined location having a system location ID wherein the control system is configured to assign this system location ID to the component ID of the specific component. Another way has been to place the component at its location and manually reading component ID which thereafter is input in the control system to be associated with the system location ID representing the actual position where the component is mounted. Both these systems are vulnerable for mistakes by a programmer or operator. In the first case may the component be mounted at the wrong location and in the second case may the unique identification be misread or assigned to another physical location in the HVAC system if its unique ID is entered to a faulty position in the control system.
[0005] The systems described above could be improved by using a more automatized process for configuring the control system and adapting these systems to assure that the components are configured properly in the control system. A highly automatized systems for the set up and control of a HVAC system is disclosed in US 2015 I 327 010 which suggests the use GPS data and/or altitude measurements for verifying a location in a building. The building equipment itself could comprise the tools for deciding its position and report it to a central controller. The location of the building equipment may be used to associate the building equipment with other building equipment for generating control parameters and algorithms. Another automatized procedure is disclosed in US 2015/120063 which describes a way to configure a HVAC system having individually controlled components, each one with a unique ID. However, the process includes the need to bring each component in the system to be assigned with a unique ID in close proximity to a main system controller to be done before mounting. This could be an obstacle if the components are heavy and/or bulky and they need to be carried to the main system controller. In addition, the components could not be mounted if the main system controller is not available. Hence, these systems are based on the existence of a working advanced control system which may be accessed during installation which not always may be the case, e.g. when installing the HVAC-system in a building during construction phase or when upgrading an existing HVAC system having a less advanced system.
[0006] There is thus a need for a system which may reduce the probability for mistakes made in the configuration of the control system for a HVAC system which may be used also without access to and need to communicate with an advanced HVAC control system during configuration.
DISCLOSURE OF THE INVENTION
[0007] The invention relates to a method for configuring components forming part of a control system for an air ventilation system and an air ventilation system adapted to be configured according to the method. The present invention describes a possibility for an automatized process allowing the components to be mounted at their location in the ventilation system before they will be configured in the control system.
[0008] According to an embodiment of the invention are all the components which shall be individually recognized in the control system provided with a component ID. This may have been provided already at the manufacturing process or at a later stage, it may even be done when the components are mounted. However, the important feature is that the components to be used in the control system have been assigned a unique component ID before they may be configured in the control system. The unique component ID should be marked on the product such that it may be identified automatically and to be selectively identified for each component by an identifier. The marking may be any kind of code or text that may be identified from a distance with an identifier. In general is this marking of the product some kind of visible label, e.g. a bar 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 it is only the product to which the reader is directed which possibly may be read by the reader, i.e. there should not be a possibility that the selected component could be mistaken for any other component.
[0009] In general, the word "component" has in this disclosure been reserved for an element forming part of the air ventilation system and is intended to be connected to the control system via a transmitter and/or receiver. The communication may be by wire or wireless. In most cases are the components adapted to both transmit and receive signals 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 air flow, e.g. dampers in the air ventilation ducting systems, fans for providing an air flow in the air ventilation system, heat exchangers for controlling the temperature of the air flow or air diffusers in the rooms or spaces to be ventilated. Other kind of components which may form part of the control system are different kind of sensors, e.g. humidity sensors, temperature sensors, carbon dioxide sensors or occupancy detectors, or user interfaces where it is possible to require certain features, e.g. a thermostat for setting a desired temperature or a control button for requesting an increased ventilation for a specific time. Hence, the control system may include any component which may provide relevant information concerning present and desired conditions for the comfort and air quality in a room or space as well as adjustable control devices which influence the quality and quantity of air to be ventilated in a certain room or part of a building. In particular, the invention is intended to encompass components selected from the group of components related to control the flow in the ducting system for providing ventilated air to a room. Hence, in one embodiment is the expression "component" intended to refer to air flow control components located in a room at the outlets of the air ducting system, e.g. air diffusers or induction devices, which are intended to control the air flow into a room from the air ducting system. In another embodiment is "component" intended to refer to a broader range of air flow control components encompassing essentially all kind of air flow control devices which may be controlled to physically influence the air flow in the ducting system from a central air flow inducing unit such as a fan to the outlets of the air ducting system, e.g. dampers or valves in the ducting system as well as the air flow control devices located at the outlets.
[0010] The components to be configured in the control system are provided with some kind of signal system. The signal system is intended to be used to recognize that the component is selected, e.g. identifying the component by its component ID. It could also be used for other purposes, e.g. for indicating the status of a component. This signal system may for 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 is selected. In this case is the important thing with the indicator that it is physically connected to a specific component and may be easily recognized and used to identify when the selected component is located.
[0011] In order to identify a specific component or a group of components is an identifier used. The identifier is of course designed to function and interact with the components and may thus be designed to function in different ways depending on how the component ID is marked onto or comprised in the components. The identifier could 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 an identifier, e.g. one unit for decoding or reading the identity and another unit for displaying the selected component or components. Hence, an identifier as described herein always includes the feature of being able to identify one component. When a component has been selected, there is a confirmation on the selected component itself revealing its status as being selected by its signal system, e.g. a blinking light. In addition, there could be some kind of recognition signaled by the indicator that its component ID has been read by the identifier. The selected component could also be displayed in the identifier and/or there could be a sound from the identifier indicating that the component has been selected and/or its component ID has been read. However, this recognition on the identifier is an optional feature to complement the indication on the component itself.
[0012] Above it has been explained the function of some of the devices used in the system as well as defining some of the terms which will be used in the method explained below for configuring components in an air treatment system such as a Heating and Ventilating Air-Conditioning (HVAC) system. The components forms part of a control system for the air ventilation system and the control system comprises one or several components selected from the groups of flow control components such as fans, dampers and air outlet diffusers, sensor components which for example sense temperature, humidity, carbon dioxide content or input control components such as user interfaces or other control buttons or levers for setting a desired condition. Also displays for indicating conditions could be included as a component in the air ventilation control system as well as heat exchangers. The components are connected to a central control unit when the components are configured and the air treatment system is in use such that the central control unit may control the air ventilation system and the quantity and quality of the ventilated air. Depending on their functions are the components provided with a transmitter and/or receiver for sending an input signal to the central control system to be used for information purposes or computing a control output command by the control system and/or receiving an output signal from the central control system in order to send information or control the component associated with the respective transmitter and/or receiver. In general, the components are provided with a transceiver allowing a component to send and receive information signals. Each of the components is further provided with an Electronic Control Unit (ECU) and an indicator connected to the associated ECU. The ECU is programmed to activate the indicator so as to indicate when the component has been selected by an identifier sending an identification signal selecting the component which may for example be used during configuration of the central control system.
[0013] The configuration comprises the steps of: 1. I. Preparation, in which the components and the identifier are prepared to be able to configure the setup of the system, 2. II. Selection procedure, in which a component is identified by its identity and location in the system, and 3. III. Configuration, in which the component is configured in the control system so as to be able to be identified concerning its location and identity by the central control unit [0014] These steps are intended to be performed in the order described above, at least to such an extent that the first step should be finished before the second step is finished and the second step will be finished before the third step is finished for at least one component. Each of these steps will now be further explained in detail below.
[0015] The first step, preparation (I), has been divided into two different preparatory procedures, step a and step b, which may be performed in any order. In one of these steps, referred to as step a, is one or several of the components which have been described above located at its intended physical location or position in the air ventilation system. Preferably the component is mounted as it should be incorporated in the system when the system is working but this is not necessary, it may just as well be merely placed at its location or provisionally mounted in order to be completely mounted in the system at a later stage. A component which is located at an intended position in the system has been assigned a unique component ID before it was located at its intended position or it may be assigned a unique component ID after it has been located at its intended position. However, in many cases a component is assigned a unique component ID already when it is manufactured at the factory. The unique component ID should be marked on the product such that it may be read automatically and to be selectively read for each component by an identifier. Whatever marking system that is used is the system intended to function such that it is only the product to which the reader is directed which possibly may be read by the reader, i.e. there should not be a possibility that the selected component could be mistaken for any other component.
[0016] In another step, referred to as step b, is the identifier provided with a system description of the air ventilation system. This system description is a representation of the air ventilation system which may be more or less detailed, e.g. a 3-D image revealing essentially the complete air ventilation system, a simpler plan view merely indicating the more relevant features of the air ventilation system or configuration tree. However, the system description shall at least comprise information concerning how the components forming part of the control system are referred to by the central control system and where in the air ventilation system they are located. Hence, the system description should include a configuration list with system location IDs for components in the air treatment systems which will be connected to the central control system. By configuration list is herein intended to include any kind of formalized information providing information of system location IDs which may be used when assigned to a component to be readily recognized by the central control system to identify the kind of component and where it is located in the air ventilation system. Hence, by performing step a and b will the air ventilation system be ready for the next main step in the configuration method, the selection procedure (II).
[0017] The selection procedure (II) has been divided into two partial steps, step c and d, which will be performed as described below.
[0018] In step c is the physical location of the desired component to be configured in the air ventilation system identified. In general, this means the person who is configuring the system will walk to be in the vicinity of the desired component to be configured. The identifier should be brought to this location and located to be in reach for wireless communication with the desired component. Hence, the identifier may now communicate with the desired component. The person who is at the location should also be aware of which of the components in the system he is selecting as the desired product. It shall be noted that step c could be performed before step a and/or b. however it is therefore described that the preparation (I) not necessarily must be completed before the selection procedure (II) starts even if it is in general not an efficient way of working.
[0019] In the next step, step d, is the identifier used for sending an identifying signal in order to identify the desired component. The signal sent from the identifier may thus reach a desired component via wireless communication or signaling. The identifying signal is an automatic reading of the marking on the component comprising information concerning the component ID. This identification should be performed such that the signal will positively recognize only the desired component. The Electronic Control Unit associated to the selected component is programmed to activate the indicator provided on the component so as to indicate when the component has been selected by the identifier. There may also be an indication in the identifier, e.g. on a display, that the component has been identified to be used and be paired in the next configuration step (III).
[0020] In the configuration step (III) is a pairing event performed, this step is also referred to as step e. In the pairing event is the desired component, having its unique component ID, paired with the system location ID. The pairing event could be performed automatically when the component ID is recognized but preferably is there some control feature or action initiated by the operator, e.g. could the system location ID be displayed in the identifier. In addition, if the feature is available, could the desired component indicate it is in a selected state. By pairing these IDs, the component ID and system location ID, is it meant that these IDs are connected to be recognized by each other. For example, the pairing event may include the feature of assigning the location ID to the component such that the component may be recognized by the system location ID as well as by its original component ID. Another way to perform this could be to send information to the central control unit to recognize the component ID for the desired component which could be used when the central control unit is receiving or sending information to the component located at the place which is assigned to the selected system location ID used in this pairing event. Or as still an alternative, the paired system location ID and component ID may be stored in a separate memory and be used as a look up table or translator when sending information from the central control system to the desired component. Hence, there are many ways of performing the pairing event such that the desired component may be recognized by the system location ID by the central control unit. An advantage with the system and method described above is that there is possible to get a feedback for a technician performing configuration or commissioning of a component directly without being connected to the central control system. Since the indicating device is located on the component itself and its indicating signal is controlled by the local ECU it is possible to know that the component has been selected also when there is no contact with the central control system. The identification of the component may be stored in a local memory connected to the identifier or even be paired in the memory of the identifier. The component ID may later on be transferred to the central control system and such that the component ID is recognized by the system location ID.

DETAILED DESCRIPTION
[0022] In figure 1 is disclosed a ventilation system 100 in a room 101 in a building (not shown). The ventilation system 100 comprises a multitude of components (1 a-1f) which are connected to a ducting system 102 and forms part of a ventilation control system. Among the components (1 a-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 provides for heat exchange of fresh air intake and exhaust air and induce a flow in the ducting system 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 air outlet 104 which are connected to the ducting system 102.There are also present a number of sensor components (1e - 1g) in the room 101 such as a carbon dioxide sensor (1e) also referred to as CO2 sensor, a humidity sensor or RH sensor (1f) wherein RH means Relative Humidity and a temperature sensor (1g). There is also present a user interface (1h) which may be a control input device for setting a desired temperature or for demanding increased ventilation for a predefined time limit. The user interface (1g) could also comprise a display for information concerning present conditions in the room 101. These components (1a - 1h) only serve as a few examples of different components which may be present in the ventilation system. In general, the word "component" has been reserved in this description for devices which forms part of a control system for the ventilation system, i.e. devices which control the flow and/or the quality of the ventilation air as well as sensors for indicating relevant properties of the air or user inputs for setting desired values for air properties.
[0023] When the ventilation system 100 is functioning are the components (1a-1g) which forms part of the control system connected to a central control unit (CCU) 105 which has been located close to the main ventilation unit 1c. In general, the main ventilation unit 1c and is located in another room and is adapted to provide for ventilation in several rooms or even one or several buildings. However, the main ventilation unit 1c has been located in the room 101 in this example for serving the purpose of illustrating and to understand in a better way how the ventilation system 100 works. In this example has the central control unit (CCU) 105 been located close to the main ventilation unit. Such a CCU 105 may be designed to control one or more main ventilation units and components associated to the ventilation systems. Hence, there is in general neither present a CCU 105 in every room and the CCU 105 is included for better illustrating the control system of the air ventilation system.
[0024] In figure 2 is disclosed a general description for features which are common for all the components (1a - 1g) which are disclosed in figure 1 and are intended to form part of a control system for such an air ventilation system 100 as exemplified in figure 1. The component is exemplified by an air diffuser 1 a but could have been any of the other components disclosed in figure 1 or any other component which is intended to form part of a control system for such a ventilation system 100 as disclosed in figure 1.
[0025] The air diffuser 1a comprises a transceiver 2 which may be used for communicating with the CCU 105 (se figure 1). The transceiver 2 is adapted to be able to transmit and receive signals and could be designed to be wireless or connected by wires to the 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 control signals and information to be transmitted and received by the transceiver 2. The transceiver 1a could be substituted for a transmitter or receiver if the component only needs to transmit or receive a signal.
[0026] The air diffuser 1a has further been provided with a unique component ID referred to as clD. In general may this this unique clD be represented by a long row of number and letters, e.g. 00:20.8C:00:08:17:54:6D. In many cases is this unique clD in addition to be component specific also giving information about product category and product kind. The products clD may be comprised visually, e.g. by marking the product with a readable plain text as above. The clD could also be programmed into the ECU 4 or comprised in a RFID. In addition, the product identity could be marked on the product by code intended to be read by an identifier. In this figure a label 5 has 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 comprised in this visible code should at least provide the clD for the component. The plain text as disclosed above could also be used but such text is in general less reliable to be read from a distance. The unique clD is generally provided at the factory but may also be assigned later on if desired.
[0027] In figure 2 has the component 1a been assigned a component ID (clD) which has been shortened compared to what is normally used in order to better illustrate how such an ID may be built up to serve different purposes. The component 1a has been assigned the clD "FC:AD:0001" which is written beside the component. This clD is intended to provide the information that the component belongs to main group flow controllers (first two digits FC), further to subgroup air diffusers (third and fourth digits AD) 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 category and kind as well as being a unique identification of the component. This information is thus comprised in the label 5 which is marked on the product.
[0028] As is obvious, the code marked on the label 5 will differ for each component 1a- 1 g, this is of course valid for the four individual air diffusers 1a (se fig 1) also if the system described herein is used. Also the ECUs 4 will most probably differ for each component, e.g. by having the unique component ID stored in its memory. Ό029] A list of the component IDs in figure 1 could be the following:
[0030] In 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 of components while the third and fourth digits are dividing the groups into subgroups depending on the product categories and the last four digits will give each component a unique component ID (clD).
[0031] In order to get the air ventilation system in figure 1 to work properly the control system must be configured. The components 1a-h needs be mounted to the air ventilation system 100 at appropriate locations and connected to the central control unit 105. The central control unit needs to know which components that have been mounted at which location. In some cases, e.g. when a group a components are intended to be controlled in exactly the same way, may it not be necessary to know exactly 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 in exactly the same way may it be enough to group these four units together and use the same identity when sending control commands from the CCU 105 to the air diffusers 1a. However, the CCU 105 must be able to recognize the four components located at these places.
[0032] Figure 2b only differs from figure 2a in that the component 1a has been provided with an indicator 3. The indicator could be a light source such as LED light or diode. The indicator is intended to indicate a status of the component 1a and could be used in the configuration of the control system by for example indicating a component is selected, a pairing event is occurring or that the component has been configured in the air ventilation system. However, this feature is optional for the system and the configuration method described herein.
[0033] In order to be able to control the air ventilation system has the location of each component which is included in the air ventilation system been provided with a system location ID according to a system description. This system description may define different groups or zones. For example, room 101 in figure 1 could be defined by being located in building 3 of a complex of buildings. The building may thereafter be divided in sections, e.g. could different floors be different sections. The room 101 could be located in section A corresponding to a floor. The section may thereafter be divided into different rooms and the room 101 in figure 1 could be assigned to be room 3. These definitions could for example be used such that all components in this room will be assigned a system location ID (sl-ID) which starts with 3A4 indicating building, zone respectively room.
[0034] In figure 3, which is based on the very same figure as is presented in figure 1, is disclosed a system description in which all the components are marked with a system location ID (sl-ID). A system description is thus a representation of the air ventilation system 1 disclosed in figure 1. At the top of the system description is written "room 3A4". This means these three characters are intended to be the 3 first digits for each system location ID for the components represented in figure 3 and the last digits are written at each represented component. As can be seen in figure 3 all represented components have been provided with a unique sl-ID. This is essentially necessary for all components with the exception for the air diffusers which could have been assigned the same sl-ID if they are intended to be controlled in the same way.
[0035] In order to configure the air ventilation control system is there a need to connect the sl-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 the respective ECUs 4 for each component 1a-g in order to know which component 1a-g which the CCU is communicating with via their transceiver 2.
[0036] In order to connect these IDs, clD and sl-ID, are the physical components located at its intended positions, preferably mounted to the air ventilation system 1 as they should be connected. In figure 4 this is illustrated by also having appointed the component ID besides each component. However, there has been provided an inequality sign between the different identities since there is no connection or recognition between the identities at this moment.
[0037] In order to make the component mounted to the air ventilation system, having its component ID, to be able to be recognized by the central control unit 105, must these two identities identify each other. This could be made by a pairing event. The operator is selecting which component to be identified from the system description, i.e. selecting a defined system location ID and position himself where the component is mounted, at a location where the component ID may be identified by using the identifier, e.g. by optical reading of the label 5 of a component comprising information concerning the component ID. The correct system location ID is selected from a list of components in the identifier. Thereafter the identifier is used to identify the component ID of the component and the component ID read from the label 5 may be connected, i.e. paired, with the system location ID. The pairing may result in that the component will be provided with the identification such that it recognizes a signal from the CCU 104 directed to the paired system location ID, the component ID could be stored in the CCU such that it will send signals addressed to the component ID and/or store the paired connection in a separate translator which is used when transferring 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 described herein. When all units have been paired is thus the control system for the air ventilation system configured and there is possible for the components at each location to be readily controlled by the CCU. Hence, in figure 5 is the system disclosed after the pairing action has been completed for all components and this is thus described by marking the connection between the identities with a sign of equality.
[0038] In figure 6 is disclosed a diagram concerning the configuration procedure.
[0039] The configuration is divided into three main procedures to be performed: Preparation (I), selection procedure (II) and configuration (III).
[0040] In the preparation (I) are there two steps which are performed, step a which is represented by the first block and comprises the feature of locating the components 1a-h in the air ventilation system, and step b which is to prepare the identifier by loading a configuration list of the air ventilation system comprising system location ID for the components 1a-h in the air ventilation system 101.
[0041] In 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 system 1 is working. In general, it is desired to mount all components, or at least all components in a zone or area, before the configuration of the control system is started but the configuration of a component could also be made if only one single component is located at its location in the system. The components are in general already provided with a unique component ID when manufactured. Otherwise this may be performed at any time before the system shall be configured, e.g. when mounting. If all components are mounted to the air ventilation system, and the components have been provided with a component ID, and no configuration of any component has been made should the air ventilation system be in the state as disclosed in figure 4, i.e. all components at their right location but no connection or identity between the system specific system location ID and the component specific component ID.
[0042] In step b is the identifier provided with a system description of the air ventilation system. This system description could for example be the plan view in figure 3 wherein the location of each component is shown and has been provided with a system location ID. This plan view, or at least a configuration list with system location IDs for components of the plan view, may thus be loaded into the identifier. As is obvious, it may also be possible to only load a few of all components into the identifier if that should be desired for some reason as long as it comprises the system location ID of the component or components to be configured. Hence, the components for which step a and step b has been made now may be selected in the selection procedure (II) to be configured.
[0043] In the selection procedure (II) are there two partial steps, step c and d, wherein a desired component is selected in step c and its component ID is identified in step d.
[0044] In step c is the identifier brought to be at a location wherefrom it may identify the desired component. In the case of identifying the component by an IR code reader reading a label with a code on the component should thus the code reader be at a suitable distance for being able to read the label. The identifier is thus ready to be used for identification of the clD of the desired component. The desired component is selected from the configuration list in the identifier, either directly from a representation of a system description comprised in the identifier or by selecting a system location ID from a configuration list corresponding to the system location ID in a plan view.
[0045] In the next step, step d, is the identifier used for sending an identifying signal in order to identify the desired component. The identifying signal is an automatic reading of the marking on the component comprising information concerning the component ID, e.g. an IR-signal for reading a coded label. In this way the component ID may be positively recognized from a distance. There is preferably an indication in the identifier, e.g. on a display, that the component has been identified to be used and be paired in the next configuration procedure (III). In addition may there be an indication on the component itself if it has been provided with an indicator controlled to confirm identification when being identified by the identifier.
[0046] In the configuration procedure, comprising step e, is the component configured in the control system so as to be able to be identified concerning its location and identity by the central control unit. This may be achieved by a pairing event in which the desired component, having its unique component ID, is paired with the system location ID. The pairing event could be performed automatically when the component ID is recognized but preferably is there some control feature or action initiated by the operator, e.g. could the system location ID be displayed in the identifier. In addition, if available the feature is available, could the desired component indicate it is in a selected state. By pairing these IDs, the component ID and system location ID, these IDs may be connected to be recognized by each other and the component may be controlled by the central control unit.
[0047] The pairing event may be indicated in the identifier and/or on the component, e.g. by a flashing light while the component is pairing and then allow a light on the product to light or marking the location system ID in the identifier as being paired when the component is paired.
[0048] The identifier which is used for the identification and pairing of the components could be designed to either directly transfer the information to the central control unit or storing a number of paired components to be transferred as batch. For example, it may be desired to complete pairing of all components in a room before the pairing of the 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, if they are provided with a light indicator, be controlled to be off when unpaired, to be turned on with a fast blinking light when selected and during its pairing event where after they turn to blink with a lower frequency when they are paired but yet not have been accessible by the central control unit where after the light is turned on constantly when the component is configured to be recognized in the air ventilation control system by the central control unit.
[0049] The status of the system in figure 5 thus corresponds to the state when all products have been paired and configured in the system.
