In particular, the method comprises a step of positioning, wherein the AHU 1 is positioned in the operative space OS. In particular, in the positioning step, each module 100 of the plurality of module is positioned in a correspondent operative zone Z (operative position in the predetermined layout).
[0207] In the step of positioning, a central control unit 200 of the AHU 1 is positioned within a correspondent location of the operative space OS.
[0208] The method includes a step of connecting. In the step of connecting, one or more of the following connections may be performed.
[0209] Each module 100 is connected with the central control unit 200. In particular, according to an embodiment, wherein each module has a corresponding peripheral controller 103, each peripheral controller 103 is connected with the central control unit 200. In the step of connecting, each peripheral controller 103 is connected with the central control unit 200 by means of a power cable PC, to be feed by the central control unit 200 with electric energy. In the step of connecting, each peripheral controller 103 is connected with the central control unit 200 by means of a signal cable SC, to exchange digital and/or analogue signals with the central control unit 200.
[0210] In the step of connecting, each peripheral controller 103 is connected with the respective one or more sensors 101 of the module 100. In particular, according to an embodiment, the connection between peripheral controller 103 and said one or more sensors 101 is an analogue connection. This connection allows the one or more sensors 101 to send control signals 101 to the respective peripheral controller 103.
[0211] In the step of connecting, each peripheral controller 103 is connected with the respective one or more actuators 102 of the module 100. In particular, according to an embodiment, the connection between peripheral controller 103 and said one or more actuators 102 include a power transmission and/or a signal transmission. This connection allows the one or more actuators 102 to receive command signals 102 to the respective peripheral controller 103.

[0214] The step of positioning is performed based on a predetermined layout that is provided to the operator. Each module 100 of the plurality of module must be controlled in a certain way depending on its position within the predetermined layout.
[0215] Hence, the method includes a step of programming.
[0216] In one embodiment, the step of programming may be on site, after the peripheral controllers have been positioned. In other embodiment, the step of programming may be on factory, before the AHU is sent to the client.
[0217] The step of programming allows to characterize each module 100. In fact, before the (on-site or on-factory) programming, each module 100 of the plurality is suitable to be positioned in any position of the predetermined layout in which is provided a module 100. With the (on-site or on-factory) programming step, each module is differentiated depending on the position in which it is really and physically disposed (or, depending on the sensors and the actuator to which it is connected). This feature avoids any error by the operator on disposing the wrong module in a certain position of the layout.
[0218] Hence, the step of (on-site or on-factory) programming includes a step of transferring control data 103, representative of a control logic to be installed in the respective module 100, from a programming device PD to the respective module 100. In other words, in the step of (on-site or on-factory) programming, each peripheral controller 103 is programmed according to the position in which the correspondent module 100 is located in the operative space.
[0219] In one embodiment, the step of transferring control data 103 is made through a near-field communication technology NFC.
[0220] When the programming step is performed on site, the programing step is preferably performed after the step of positioning.
[0221] More in particular, after the step of positioning, the operator holds the programming device PD, which could be simply a smartphone or a table or a personal computer and approaches each module 100 of said plurality in order to program it. The operator selects, preferably on the screen of the programming device PD, the module which is displayed on the virtual layout in a position that correspond to the real position of the module. The programming device PD, based on the positioned of the module selected on the screen, prepare the control data 103 corresponding to the control logic to be installed in the selected module 100. The programming device PD transmits the prepared control data 103 to the proximity receiver 408 of the respective module 100 to install on the peripherical controller 103 the designed control logic. This step of transmitting is done for each module 100 of the plurality of module.
[0222] In other words, the plurality of modules is selected among a database of modules in a selection software. In particular, the client may customize is AHU and, according to the client selection, the modules are picked from a database of modules. After all the modules are defined, whit all their components, the software is also able to draft an economical offer.
[0223] When the order is performed, the software sends all the information regarding the modules, in particular all the components and the position of the modules in the AHU layout, to an operator, which can install the AHU, trough the software, in the factory or even on site during the assembly of the AHU, according to the received specification.
[0224] More in particular, the present description provides also a method for programming control logics on a plurality of modules of an air handling unit, AHU, through a programming device including a processor.
[0225] The method includes a step of receiving F1 layout data 10, representative of a predetermined layout, according to which the modules of the plurality of modules are operationally interconnected.
[0226] The method includes a step of receiving F2 control data 103, representative of a plurality of control logics. Each control logic is associated with a corresponding module 100 of said plurality of modules.
[0227] Each control logic is associated with a corresponding module 100 of said plurality of modules, based on an arrangement of the module 100 in the predetermined layout.
[0228] The control data 103 and/or the layout data 10 may be received by the processor in one or more of the following ways: [0229] read on a remote server the layout data and/or the control data associated to a specific custom project, the layout data being generated by an operator in another terminal during a designing step; [0230] import, through an importing module of the programming device, the layout data and/or the control data; [0231] receive the layout data and/or the control data by email or by a wireless connection; [0232] receive the layout data through a mobile communication or a Narrow Band.
[0233] In one embodiment, each module may be classified within a set of categories, according to his function and/or his position. In one embodiment, the processor receives from an operator, which is designing the AHU, a category to which each module belongs to.
[0234] In one embodiment, the processor read on a remote server the control data of each module 100, based on the category to which the respective module 100 belongs to.
[0235] The method includes a step of receiving F3 an identification input 11, representative of a selection of a module 100 to be programmed by an operator.
[0236] For example, the identification input 11 may be a selection of a specific module 100 by touching it on a touch screen of the programming device PD, where is displayed a virtual predetermined layout.
[0237] In one embodiment, the method comprises a step of transferring F4 of selected control data 103, representative of a control logic associated with the selected module to be programmed. The selected control data 103 are transferred from the programming device PD to a corresponding peripheral controller 103 of the module 100 to be programmed.
[0238] Preferably, the step of transferring F4 the selected control data 103 is carried out by means of a near-field communication, NFC, technology.
[0239] In one embodiment, the processor is configured to group control data 103 based on the predetermined layout, to define a new group of control data 103 (define new control logic) which is not yet present in the database of control data (control logics). The processor is configured to save the new group of control data 103 (the new control logic) in the database, in order to be implement directly for future projects.
[0240] For example, if the user implements a number of sensors in a module which are greater than the maximum number of sensors manageable by each single group of control data 103 in the database (by the control logics present in the database), the processor may select two group of control data 103 (two existing control logic), which are, in combination, able to manage all the sensors. However, these solutions work with two peripheral controllers, each one programmed with the respective group of control data 103 (with the respective control logic). In other embodiments, the processor, if the peripheral controller is physically able to manage all the sensors, creates a new group of control data 103 (new control logic), which are programmed to control a peripheral controller which implements all the sensors together. Hence, just one peripheral controller may be used for the same number of sensors.
[0241] Moreover, the database of control data 103 is continuously updated with new group of control data 103 which may cover the different needs of the clients.
