     Embodiment 1 
     Background Art of Embodiment 1 
       FIG. 1  is a diagram showing an example of group setting information of an air conditioner managing console  2  in background art that is a premise of the present invention. As shown in  FIG. 1 , a setting information table  11  is composed of, for example, group name data, group number data, and registered unit data. A group name  60  (described later) includes, for example, a group [A], a group [B], a group [C], and a group [D]. The group number data includes, for example, a group [01], a group [02], a group [03], and a group [04]. The group name data may not be included in a component of data. 
     The registered unit data includes, for example, an indoor unit address [001] and an indoor unit address [002] corresponding to the group [01]. The registered unit data includes, for example, an indoor unit address [003] and an indoor unit address [004] corresponding to the group [02]. The registered unit data includes, for example, an indoor unit address [005] and an indoor unit address [006] corresponding to the group [03]. The registered unit data includes, for example, an indoor unit address [007] and an indoor unit address [008] corresponding to the group [04]. Here, each indoor unit address only needs to be intended to specify any of a plurality of indoor units  4  (described later), and any value is assumed to be set as the indoor unit address. 
     Next, a floor layout is assumed to be divided into a plurality of small spaces. With this assumption as a premise, the group name  60  (described later) is associated with each of the plurality of small spaces. For example, the group name  60  (described later) is set as A, B, C, and D. In addition, a group number is associated with each group. For example, a group number “01” is associated with the group A, a group number “02” is associated with the group B, a group number “03” is associated with the group C, and a group number “04” is associated with the group D. 
     The address of an air conditioner, for example, an indoor unit  4  (described later), is associated with each group. For example, an indoor unit address “001” and an indoor unit address “002” are associated with the group of the group number “01”. An indoor unit address “003” and an indoor unit address “004” are associated with the group of the group number “02”. An indoor unit address “005” and an indoor unit address “006” are associated with the group of the group number “03”. An indoor unit address “007” and an indoor unit address “008” are associated with the group of the group number “04”. 
     That is, the setting information table  11  is configured such that the air conditioners, for example, the indoor units  4  (described later) are managed on a group basis in accordance with the floor layout. Thus, the setting information table  11  is configured such that each group and the air conditioners, for example, the indoor units  4  (described later) are allocated. Specifically, the setting information table  11  is configured such that the addresses of the air conditioners, for example, the indoor units  4  (described later) are allocated to each group on a group basis of group numbers  70  (described later). 
     The setting information table  11  as described above is configured, for example, on a screen of the air conditioner managing console  2  described later. For example, when the air conditioner managing console  2  described later shifts to an initial setting mode, the air conditioner managing console  2  may display the setting information table  11  on an initial setting screen. The addresses of the indoor units  4  (described later) to be allocated corresponding to groups required in management are set through such an initial setting screen. Here, the air conditioner managing console  2  described later is assumed to be able to manage a plurality of groups. 
     Meanwhile, in a building occupied by offices, various tenants, and the like, a floor layout may be changed due to change of a user or the like, and division and integration of groups or the like may occur. Thus, each time the floor layout is changed, group setting, for example, change of group formation may be performed. 
       FIG. 2  is a diagram showing an example of a monitoring screen  31  of the air conditioner managing console  2  in the background art that is the premise of the present invention. The monitoring screen  31  has display contents configured on the basis of the setting information table  11  described above, and operation states of groups to be managed by the air conditioner managing console  2  described later are reflected in the display contents. 
     The monitoring screen  31  includes, for example, a grid screen button  41 , a list screen button  42 , a group screen button  43 , and a main menu screen button  44  at the upper side thereof, and a current time  51  is displayed thereon. The monitoring screen  31  includes, for example, a group name  61  to a group name  65 , a group number  71  to a group number  75 , and a group icon button  81  to a group icon button  85  at the center thereof. The monitoring screen  31  includes, for example, a selection operation panel access button  101 , a zoom-out/zoom-in button  102 , a left triangle button  103 , a current page number  104 , a right triangle button  105 , a select-all button  106 , and an operation button  107  at the lower side thereof. 
     For example, a heating mode display sign  91  is displayed in the group icon button  81 . For example, a heating mode display sign  91  and a check mark  93  are displayed in the group icon button  83 . For example, a filter replacement sign  92  is displayed in the group icon button  84 . For example, a filter replacement sign  92  is displayed in the group icon button  85 . 
     When the group name  61  to the group name  65  are not particularly distinguished from each other, the group name  61  to the group name  65  are referred to as the group name  60  or group names  60 . When the group number  71  to the group number  75  are not particularly distinguished from each other, the group number  71  to the group number  75  are referred to as the group number  70  or group numbers  70 . When the group icon button  81  to the group icon button  85  are not particularly distinguished from each other, the group icon button  81  to the group icon button  85  are referred to as the group icon button  80  or group icon buttons  80 . Here, the group name  60 , the group number  70 , and the group icon button  80  are displayed so as to be associated with each other. 
     Here, as shown in  FIG. 2 , groups to be managed are displayed as icons on the monitoring screen  31 . Such icons are configured, for example, as the group icon button  81  to the group icon button  85  described above. 
     The group number  70  (described later) is displayed in each group icon button  80 , and the group icon buttons  80  are displayed so as to be aligned in order of the group numbers, for example, in ascending order of the group numbers. In each group icon button  80 , the operation state of the indoor unit  4  (described later), for example, any of an operation state, a stop state, an abnormal state, and the like thereof may be displayed. Each group icon button  80  is configured, for example, as a button that issues an operation command to either operate or stop the indoor units  4 , and when an operation such as pressing is performed on the group icon button  80 , the operation state or the like of the corresponding group is changed. 
     Meanwhile, when a floor layout is changed, resetting of the groups is required, and a great workload is taken for such resetting of the groups.  FIG. 3  is a diagram showing an example of a group setting change corresponding to a floor layout in the background art that is the premise of the present invention.  FIG. 3  shows an example in which the setting information table  11  described above transitions from a state  111  before setting change to a state  112  during setting change. 
     For example, it is assumed that a floor is divided into small spaces of a floor A, a floor B, a floor C, and a floor D and then the floor A is divided into a floor A and a floor E. Here, it is assumed that in the state  111  before setting change, among the floor layout, the floor A corresponds to the group [A], the floor B corresponds to the group [B], the floor C corresponds to the group [C], and the floor D corresponds to the group [D]. In addition, it is assumed that in the state  112  during setting change, among the floor layout, the floor A corresponds to the group [A], the floor B corresponds to the group [B], the floor C corresponds to the group [C], the floor D corresponds to the group [D], and the floor E corresponds to a group [E]. 
     Specifically, initially, a group to be added by division is set. For example, a group [05] is newly added as a management target group for the floor E. The indoor unit address [002] registered in the floor A is registered therein. Next, the indoor unit address [002] registered in the group [01] as a management target group for the floor A is deleted, and the work is completed. The result will be described with reference to  FIG. 4 . 
       FIG. 4  is a diagram showing an example of the monitoring screen  31  of the air conditioner managing console  2  after group addition in the background art that is the premise of the present invention. As shown in  FIG. 4 , in comparison with a display screen  121  before setting change, the groups are displayed on the display screen  122  during setting change so as to be aligned in order of the group numbers  70 , for example, in ascending order of the group numbers  70 , but rearrangement has not been executed. Thus, the group icon button  81  corresponding to the floor A and the group icon button  85  corresponding to the floor E are displayed at positions away from each other. 
     Thus, to match the actual layout, the display position of the group icon button  85  corresponding to the floor E needs to be changed to a position adjacent to the right of the group icon button  81  corresponding to the floor A. Specifically, a configuration change example will be described with reference to  FIGS. 5 and 6 . 
       FIG. 5  is a diagram showing an example of the group setting change corresponding to the floor layout in the background art that is the premise of the present invention.  FIG. 6  is a diagram showing an example of display of the group icon button  81  to the group icon button  85  after group resetting in the background art that is the premise of the present invention. 
     As shown in  FIG. 5 , the state transitions from the state  112  during setting change to a state  113  after setting change. Specifically, the indoor unit address [002] is registered in the group [02] corresponding to the floor E. Next, the group number  70  corresponding to the floor B is shifted by one, that is, incremented by one, as compared to the current group number  70 , and is reset as the group [03], and the indoor unit address [003] and the indoor unit address [004] are re-registered therein. Next, the group number  70  corresponding to the floor C is shifted by one, that is, incremented by one, as compared to the current group number  70 , and is reset as the group [04], and the indoor unit address [005] and the indoor unit address [006] are re-registered therein. Next, the group number  70  corresponding to the floor D is shifted by one, that is, incremented by one, as compared to the current group number  70 , and is reset as the group [05], and the indoor unit address [007] and the indoor unit address [008] are re-registered therein. The change as described above is performed, for example, by a person in charge of work. 
     When a floor partition is changed, for example, the floor partition is deleted to integrate the floors, a group to be integrated may be deleted, and an indoor unit address registered in the deleted group may be additionally registered in a group that is an integration destination. In this case as well, each group number  70  after the deleted group needs to be shifted by one to reset the groups. 
     Thus, to perform division and integration or the like of the group and to implement a group display corresponding to the floor layout, resetting of the groups is needed, but a great deal of workload is generated. For example, even if the number of groups corresponding to action of any one of the division and the integration of the group is one, resetting of the groups that do not correspond to any one of the division and the integration of the group is needed, so that a great deal of workload is generated. 
     Normally, such a group setting is not disclosed to an end user, and is made by a managing person, a constructor, and a maintenance company. Thus, to perform a group setting, necessity of requesting each company arises, so that this costs the end user. In addition, even when either one of division and integration of the group is executed and the groups are displayed in a sequence corresponding to the floor layout, as shown in  FIG. 6 , the group icon button  81  to the group icon button  85  are displayed on a display screen  123  after setting change, in the same sequence as in the display screen  121  before setting change as described above, and thus are not displayed such that a work result and a change in management scale are recognized at a glance. 
     Due to the above description, when the groups are reset in accordance with a change of the floor layout, many processes are required to the person in charge of work, and the groups are difficult to intuitively understand even after the resetting of the groups. Thus, a change of the display of the groups needs to be executed easily and a result of the change of the display of the groups needs to be recognized easily. In addition, when rearrangement of the group icon buttons  80  is executed corresponding to the change of the floor layout, a load of resetting of the groups is reduced. 
     Thus, the following configuration is desirable: a process, with less user burden, of division and integration of the group is executed when the resetting of the groups is executed corresponding to the floor layout; the display of the groups is rearranged at the time of dividing the group; and a result of the operations is reflected clearly in the display screen. With such a configuration, the groups corresponding to the layout change are displayed even with less user burden and without much cost. When a group display corresponding to the floor layout is executed, it is possible to prevent an end user or the like from making a false operation or misrecognition of the groups. Next, specific examples of such the configuration will be sequentially described. 
     (Operation Principle of Embodiment 1) 
       FIG. 7  is a diagram schematically illustrating an operation principle of the present invention. As shown in  FIG. 7 , an association setting processing unit  135  generates display contents data on the basis of setting target data supplied from setting state retention data  131  in response to an operation target selection command and a change contents command supplied from change contents data  133  in response to a change contents selection command. 
     The setting state retention data  131  has a data configuration in which, for example, the group name  60 , the group number  70 , a registration target apparatus, and the address of the registration target apparatus are linked to each other. The change contents data  133  has a data configuration including, for example, division process data, integration process data, and rearrangement process data. The association setting processing unit  135  causes resetting of groups to be performed by a simple operation according to the contents of work. This resetting is achieved by generating display contents data corresponding to the display contents of the group icon buttons  80 , by using operation target data corresponding to the operation target selection command and the change contents corresponding to the change contents selection command, from among data related to a plurality of the group icon buttons  80 . As a result, a group display corresponding to a layout change is executed with less user burden. The operation principle described above is an example, and the operation principle of the present invention is not limited thereto. Further specific examples will be sequentially described later. 
     (Configuration of Embodiment 1) 
       FIG. 8  is a diagram showing an example of a schematic configuration of an air-conditioning system  1  according to Embodiment 1 of the present invention. As shown in  FIG. 8 , the air-conditioning system  1  includes an air conditioner managing console  2   a , an air conditioner managing console  2   b , an outdoor unit  3   a  to an outdoor unit  3   d , and an indoor unit  4   a  to an indoor unit  4   h . A uniquely identified address is set for each of the air conditioner managing console  2   a , the air conditioner managing console  2   b , the outdoor unit  3   a  to the outdoor unit  3   d , and the indoor unit  4   a  to the indoor unit  4   h.    
     For example, as described above, the indoor unit address [001] is set for the indoor unit  4   a , the indoor unit address [002] is set for the indoor unit  4   b , the indoor unit address [003] is set for the indoor unit  4   c , the indoor unit address [004] is set for the indoor unit  4   d , the indoor unit address [005] is set for the indoor unit  4   e , the indoor unit address [006] is set for the indoor unit  4   f , the indoor unit address [007] is set for the indoor unit  4   g , and the indoor unit address [008] is set for the indoor unit  4   h.    
     Various signals are transmitted and received via communication transmission lines  6  by each of the air conditioner managing console  2   a , the air conditioner managing console  2   b , the outdoor unit  3   a  to the outdoor unit  3   d , and the indoor unit  4   a  to the indoor unit  4   h . A case is assumed in which the communication transmission lines  6  are wired, but the form of the communication transmission lines  6  is not particularly limited thereto. For example, the communication transmission lines  6  may be wireless. That is, the communication transmission lines  6  only need to be communication media. 
     The indoor unit  4   a , the indoor unit  4   b , and the outdoor unit  3   a  are connected to each other by refrigerant pipes, which are not shown, thereby forming a refrigerant circuit, for example, configuring a first air-conditioning apparatus. The indoor unit  4   c , the indoor unit  4   d , and the outdoor unit  3   b  are connected to each other by refrigerant pipes, which are not shown, thereby forming a refrigerant circuit, for example, configuring a second air-conditioning apparatus. The indoor unit  4   e , the indoor unit  4   f , and the outdoor unit  3   c  are connected to each other by refrigerant pipes, which are not shown, thereby forming a refrigerant circuit, for example, configuring a third air-conditioning apparatus. The indoor unit  4   g , the indoor unit  4   h , and the outdoor unit  3   d  are connected to each other by refrigerant pipes, which are not shown, thereby forming a refrigerant circuit, for example, configuring a fourth air-conditioning apparatus. 
     For the first air-conditioning apparatus, for example, the group [01] is set. For the second air-conditioning apparatus, for example, the group [02] is set. For the third air-conditioning apparatus, for example, the group [03] is set. For the fourth air-conditioning apparatus, for example, the group [04] is set. 
     The air conditioner managing console  2   a  is configured, for example, as a host apparatus in the air-conditioning system  1 . Meanwhile, the air conditioner managing console  2   b  is configured, for example, as a subordinate apparatus in the air-conditioning system  1 . The air conditioner managing console  2   a  manages operation of the air conditioner managing console  2   b , operation of the first air-conditioning apparatus, operation of the second air-conditioning apparatus, operation of the third air-conditioning apparatus, and operation of the fourth air-conditioning apparatus. The air conditioner managing console  2   b  manages operation of the first air-conditioning apparatus, operation of the second air-conditioning apparatus, operation of the third air-conditioning apparatus, and operation of the fourth air-conditioning apparatus. 
     Thus, operation states of the respective indoor unit  4   a  to indoor unit  4   h  and operation states of the respective outdoor unit  3   a  to outdoor unit  3   d  are settable by either one of the air conditioner managing console  2   a  and the air conditioner managing console  2   b.    
     The group setting information concerning the group [01] to the group [04] as described above is set, for example, by the air conditioner managing console  2   a , which is the host apparatus, and a setting result is transmitted via the communication transmission line  6  to the air conditioner managing console  2   b , which is the subordinate apparatus. As a result, the air conditioner managing console  2   b , which is the subordinate apparatus, displays the group setting information received from the host apparatus, as groups to be managed by the air conditioner managing console  2   b.    
     When the air conditioner managing console  2   a  and the air conditioner managing console  2   b  are not particularly distinguished from each other, the air conditioner managing console  2   a  and the air conditioner managing console  2   b  are referred to as the air conditioner managing console  2  or air conditioner managing consoles  2 . In addition, the outdoor unit  3   a  to the outdoor unit  3   d  are not particularly distinguished from each other, the outdoor unit  3   a  to the outdoor unit  3   d  are referred to as the outdoor unit  3  or outdoor units  3 . Moreover, when the indoor unit  4   a  to the indoor unit  4   h  are not particularly distinguished from each other, the indoor unit  4   a  to the indoor unit  4   h  are referred to as the indoor unit  4  or indoor units  4 . Next, the air conditioner managing console  2  will be described in detail. 
       FIG. 9  is a diagram showing an example of an internal configuration of the air conditioner managing console  2  according to Embodiment 1 of the present invention. As shown in  FIG. 9 , the air conditioner managing console  2  includes a touch panel display  12 , a transmitting/receiving circuit  13 , a memory  14 , a nonvolatile memory  15 , and a CPU (central processing unit)  16 . The touch panel display  12  includes, for example, an operation input unit  21  and a display unit  22 . 
     The operation input unit  21  is one of machine interfaces that receives a user operation of the person in charge of work or the like and supplies an operation result to the CPU  16 . The display unit  22  is one of machine interfaces that displays the operation state of the air-conditioning apparatus as described above. The transmitting/receiving circuit  13  transmits and receives various signals to and from the indoor units  4 , the outdoor units  3 , and the air conditioner managing console  2  other than the self-apparatus, via the communication transmission lines  6 . The memory  14  has stored in advance a program for performing function control. The nonvolatile memory  15  stores setting contents in a nonvolatile state, and stores, for example, group setting information including information concerning the group number  70  and the registered unit. The CPU  16  manages execution of function control and performs overall control of the transmitting/receiving circuit  13 , the indoor units  4 , the outdoor units  3 , and the air conditioner managing console  2  other than the self-apparatus. 
     The above-described internal configuration of the air conditioner managing console  2  is an example, and the internal configuration of the air conditioner managing console  2  is not particularly limited thereto. In short, the air conditioner managing console  2  only needs to be configured to allow a process described later to be executed. Next, group division will be described sequentially. 
       FIG. 10  is a diagram showing an example of group division in Embodiment 1 of the present invention. As shown in  FIG. 10 , the group [01] is divided into a group [01] and a group [02], the address [001] of the indoor unit  4  is re-registered in the group [01] after the division, and the address [002] of the indoor unit  4  is re-registered in the group [02] after the division. Next, the division process will be sequentially described in detail. 
     (Operation of Embodiment 1) 
       FIG. 11  is a diagram schematically illustrating transition of a data configuration occurring with group division in Embodiment 1 of the present invention. As shown in  FIG. 11 , the address [002] of an indoor unit  4  linked to the group number [01] is deleted, and the address [002] is registered as the address of an indoor unit  4  linked to the group number [02]. Next, either an operation in which the group numbers  70  linked to the address [003] and the subsequent addresses of the indoor unit  4  respectively, are reallocated, for example, to [03] and the subsequent group numbers, or an operation in which the addresses included in address tables are reset is executed. 
       FIG. 12  is a flowchart illustrating an example of a group division operation reception process in Embodiment 1 of the present invention.  FIG. 13  is a diagram showing an example of a layout screen  150   a  before group division in Embodiment 1 of the present invention.  FIG. 14  is a diagram showing an example of a group division setting screen  151  in Embodiment 1 of the present invention.  FIG. 15  is a diagram showing an example of a layout screen  150   b  after group division in Embodiment 1 of the present invention. 
     (Step S 11 ) 
     The air conditioner managing console  2  determines whether a division target group is selected. If a division target group is selected, the air conditioner managing console  2  proceeds to step S 12 . On the other hand, if a division target group is not selected, the air conditioner managing console  2  returns to step S 11 . 
     For example, as shown in  FIG. 13 , if the group icon button  81  which is target of the division is pressed by a physical object  171 , for example, a finger or the like, the air conditioner managing console  2  determines that a division target group is selected. Specifically, the check mark  93  is displayed in the group icon button  81  which is selected, and the display color thereof is changed. 
     (Step S 12 ) 
     The air conditioner managing console  2  determines whether a function of a division operation is selected. If the function of the division operation is selected, the air conditioner managing console  2  proceeds to step S 13 . On the other hand, if the function of the division operation is not selected, the air conditioner managing console  2  returns to step S 12 . 
     For example, as shown in  FIG. 13 , if a divide group button  161  is pressed by the physical object  171 , the air conditioner managing console  2  determines that the function of the division operation is selected. 
     (Step S 13 ) 
     The air conditioner managing console  2  determines whether a dividing number (the number into which a group is divided) is set. If the dividing number is set, the air conditioner managing console  2  proceeds to step S 14 . On the other hand, if the dividing number is not set, the air conditioner managing console  2  returns to step S 13 . 
     For example, as shown in  FIG. 14 , if a dividing number input button  164  is pressed by the physical object  171 , the air conditioner managing console  2  determines that the dividing number is set, and an address input button  165  is displayed in accordance with the set dividing number. 
     (Step S 14 ) 
     The air conditioner managing console  2  determines whether an address of a unit of a dividing group is set. If the address of the unit of the dividing group is set, the air conditioner managing console  2  proceeds to step S 15 . On the other hand, if the address of the unit of the dividing group is not set, the air conditioner managing console  2  returns to step S 14 . 
     For example, as shown in  FIG. 14 , if the address input button  165  is pressed by the physical object  171 , the air conditioner managing console  2  determines that the address of the unit of the dividing group is set. 
     (Step S 15 ) 
     The air conditioner managing console  2  determines whether all the addresses of the units of the dividing groups are set. If all the addresses of the units of the dividing groups are set, the air conditioner managing console  2  proceeds to step S 16 . On the other hand, if not all the addresses of the units of the dividing groups are set, the air conditioner managing console  2  returns to step S 14 . 
     (Step S 16 ) 
     The air conditioner managing console  2  determines whether an OK button  167  is selected. If the OK button  167  is selected, the air conditioner managing console  2  ends the process. On the other hand, if the OK button  167  is not selected, the air conditioner managing console  2  returns to step S 16 . 
     As a result of the above, as shown in  FIG. 15 , the result of dividing is displayed as the layout screen  150   b . The layout screen  150   a  shown in  FIG. 13  and the layout screen  150   b  shown in  FIG. 15  will be compared to each other. The group [01] is displayed as being divided into the group [01] and the group [02]. The group number  70  of the group [02] is shifted to the group [03], the group number  70  of the group [03] is shifted to the group [04], and the group number  70  of the group [04] is shifted to the group [05], and in the division process, the group numbers  70  are displayed as being reallocated. 
     Here, as a group setting, the address [001] of the indoor unit  4  is registered in the group [01], the address [002] of the indoor unit  4  is registered in the group [02], the address [003] and the address [004] of the indoor units  4  are registered in the group [03], the address [005] and the address [006] of the indoor units  4  are registered in the group [04], and the address [007] and the address [008] of the indoor units  4  are registered in the group [05]. 
     As shown in  FIG. 15 , after the execution of the division, in the layout screen  150   b , the size of group icon button  80  is set, for example, on the basis of a size in the case where one indoor unit  4  is registered. Thus, the pixel dimension is changed in accordance with the number of registered units such that when two units are registered, the width is doubled. For example, in  FIG. 15 , in each of the group [01] and the group [02], the address of the one indoor unit  4  is registered, and thus the display width is half as compared to each of the group icon button  83  to the group icon button  85  of the group [03] to the group [05] in each of which the addresses of the two indoor units  4  are registered. 
       FIG. 16  is a flowchart illustrating an example of a group division operation internal process in Embodiment 1 of the present invention.  FIG. 17  is a diagram showing an example of group setting information at the time of group addition in Embodiment 1 of the present invention.  FIG. 18  is a diagram showing an example of group setting information at the time of deletion of indoor unit data of a dividing group in Embodiment 1 of the present invention.  FIG. 19  is a diagram showing an example of group setting information at the time of registration of indoor unit data in Embodiment 1 of the present invention.  FIG. 20  is a diagram showing an example of group setting information at the time of re-registration of indoor unit data in Embodiment 1 of the present invention.  FIG. 21  is a diagram showing an example of group setting information at the time of reallocation of group numbers in Embodiment 1 of the present invention. 
     (Step S 31 ) 
     The air conditioner managing console  2  determines whether a group number (m) of a division target and the dividing number (n) are acquired. If the group number (m) of the division target and the dividing number (n) are acquired, the air conditioner managing console  2  proceeds to step S 32 . On the other hand, if the group number (m) of the division target and the dividing number (n) are not acquired, the air conditioner managing console  2  returns to step S 31 . 
     (Step S 32 ) 
     The air conditioner managing console  2  adds n−1 groups between a group (m) and a group (m+1) in accordance with the dividing number which is set. 
     For example, as shown in  FIG. 17 , one group is added between the group [01] before the division and the group [02] before the division. 
     (Step S 33 ) 
     The air conditioner managing console  2  deletes the addresses of the units that are set in the n−1 dividing groups, from the group (m) which is a division source. 
     For example, as shown in  FIG. 18 , in the addresses of the indoor units  4  included in the group [01] before division, the address of the indoor unit  4  that is to be registered in the newly added group [02] is deleted. 
     (Step S 34 ) 
     The air conditioner managing console  2  registers the addresses of the units that are set in the n−1 dividing groups. 
     For example, as shown in  FIG. 19 , the address of the indoor unit  4  that is set at the time of the setting of group division is registered in the added group [02]. 
     (Step S 35 ) 
     For the group of m+1+(n−1) and the subsequent groups, the air conditioner managing console  2  shifts the group numbers  70  by the number of the groups that are added as the n−1 dividing groups, registers the addresses of the units, and ends the process. 
     For example, as shown in  FIG. 20 , regarding each of the group of m+1+(n−1) and the subsequent groups, the group numbers  70  are shifted by the number of the added groups (n−1), and the addresses of the indoor units  4  are re-registered. 
     In the above description for step S 35 , the addresses of the indoor units  4  included in the groups that are not subjected to the division process are re-registered by shifting the group number  70 . However, the division process is not particularly limited thereto. For example, as shown in  FIG. 21 , by shifting the group numbers  70 , an operation of reallocating the group numbers  70  may be executed instead of re-registering the addresses of the indoor units  4  that are not the target of the division process. In this case, the air conditioner managing console  2  only needs to change the group number  70  for each of the group of m+1 and the subsequent groups to a number acquired by adding the value of n−1 to the group number  70 . 
     (Advantageous Effects of Embodiment 1) 
     Due to the above description, in the case of executing the division process, the air conditioner managing console  2  divides the group on the basis of the dividing number and the address of the registration target unit, and displays each group icon button  80  with a size corresponding to the number of the indoor units  4  after re-registration. Thus, since the air conditioner managing console  2  is able to perform resetting of the groups by a simple operation based on the contents of work, the air conditioner managing console  2  is able to execute a group display corresponding to a layout change with less user burden. In addition, since the air conditioner managing console  2  changes the pixel dimension of each group icon button  80  in accordance with the result of dividing, misrecognition by a person in charge of work or the like is able to be prevented. 
     Due to the above description, in Embodiment 1, the air conditioner managing console  2  which is configured to include the indoor units  4  in the plurality of preset groups and manage the indoor units  4  on a group basis includes the display unit  22  configured to display each group as an icon and the CPU  16  configured to control the display units  22 , and in which each group is set so as to be linked to one of preset small spaces into which the air-conditioning target space is divided, and when the CPU  16  receives the change command corresponding to the change of the small spaces, the CPU  16  changes the association of the indoor units  4  associated with the groups in accordance with the change command, and causes the icons to be displayed on the display unit  22  with the display contents based on the changed association of the indoor units  4 . 
     With the above configuration, by performing resetting of the groups by a simple operation based on the contents of work, the air conditioner managing console  2  is able to perform a group display corresponding to a layout change with less user burden. 
     In Embodiment 1, the group number is assigned to each group. If the change command is a division process for the groups, the CPU  16  divides the association of the indoor units  4  associated with the groups on the basis of the group numbers of the groups and the contents of the division of the group, and causes icons to be displayed with display contents based on the divided association of the indoor units  4 . 
     With the above configuration, by performing the division setting of the groups by a simple operation based on the contents of division, the air conditioner managing console  2  is able to perform a group display corresponding to a layout change occurring with the division with less user burden. 
     In Embodiment 1, when the CPU  16  displays icons, the pixel dimension of each icon is changed in accordance with the number of the indoor units  4  and the icons is displayed on the display unit  22 . 
     With the above configuration, the air conditioner managing console  2  is able to decrease the pixel dimension of each icon as the number of the registered indoor units  4  increases, and is able to increase the pixel dimension of each icon as the number of the registered indoor units  4  decreases. Thus, the air conditioner managing console  2  allows the user to recognize the rough number of the registered indoor units  4  through the sizes of the icons, and hence allows the user to intuitively understand the contents of the registration. 
     In Embodiment 1, the air-conditioning system  1  includes the air conditioner managing console  2 , the outdoor units  3 , and the indoor units  4 , and the air conditioner managing console  2  controls the outdoor units  3  and the indoor units  4  on a group basis. 
     With the above configuration, the air-conditioning system  1  is able to efficiently manage the outdoor units  3  and the indoor units  4  by causing the air conditioner managing console  2  to control the icon corresponding to each group in accordance with an operation by the user. 
     Embodiment 2 
     Configuration of Embodiment 2 
       FIG. 22  is a diagram showing an example of group integration in Embodiment 2 of the present invention. As shown in  FIG. 22 , for example, the group [01] before integration and the group [02] before integration are integrated to yield the group [01] after integration. 
     (Operation of Embodiment 2) 
       FIG. 23  is a diagram schematically illustrating transition of a data structure occurring with group integration in Embodiment 2 of the present invention. As shown in  FIG. 23 , the address of the indoor unit  4  to be linked to the group number [01] is newly registered, data related to the group number [02] is deleted, and the group number [02] no longer related to the integration is reallocated. 
       FIG. 24  is a flowchart illustrating an example of a group integration operation reception process in Embodiment 2 of the present invention.  FIG. 25  is a diagram showing an example of a layout screen  150   c  at the time of start of an integration operation before group integration in Embodiment 2 of the present invention.  FIG. 26  is a diagram showing an example of a layout screen  150   d  at the time of selection of an integration target before group integration in Embodiment 2 of the present invention.  FIG. 27  is a diagram showing an example of a layout screen  150   e  after group integration in Embodiment 2 of the present invention. 
     (Step S 51 ) 
     The air conditioner managing console  2  determines whether a group to be target of integration (referred herein as “basic group”) is selected. If a basic group is selected, the air conditioner managing console  2  proceeds to Step S 52 . On the other hand, if a basic group is not selected, the air conditioner managing console  2  returns to Step S 51 . 
     For example, as shown in  FIG. 25 , if the group icon button  81  for the integration target is pressed by the physical object  171 , the air conditioner managing console  2  determines that the basic group is selected. In this case, the check mark  93  is displayed in the group icon button  81 , and the display color thereof is changed. 
     (Step S 52 ) 
     The air conditioner managing console  2  determines whether a function of an integration operation is selected. If the function of the integration operation is selected, the air conditioner managing console  2  proceeds to Step S 53 . On the other hand, if the function of the integration operation is not selected, the air conditioner managing console  2  returns to Step S 52 . 
     For example, as shown in  FIG. 25 , if the integrate group button  163  is not pressed by the physical object  171 , the air conditioner managing console  2  determines that the function of the integration operation is selected. 
     (Step S 53 ) 
     The air conditioner managing console  2  determines whether a group to be integrated with the basic group (referred herein as “joining group) is selected. If a joining group is selected, the air conditioner managing console  2  ends the process. On the other hand, if a joining group is not selected, the air conditioner managing console  2  returns Step S 53 . 
     For example, as shown in  FIG. 26 , if the group icon button  82  which is to be integrated is pressed by the physical object  171 , the air conditioner managing console  2  determines that the joining group is selected. 
     As a result of the above operation, as shown in  FIG. 27 , the group [02] is displayed on the layout screen  150   e  as being integrated with the group [01]. The group [02] is the group [03] before the integration, the group [03] is the group [04] before the integration, and the group numbers  70  thereof are displayed in the integration process as being changed. Regarding a group setting, the address [001] to the address [004] of the indoor units  4  are registered in the group [01], the address [005] and the address [006] of the indoor units  4  are registered in the group [02], and the address [007] and the address [008] of the indoor units  4  are registered in the group [03]. Accordingly, after the integration operation, the four indoor units  4  are registered in the group [01], and thus the group icon button  81  is displayed with a doubled width dimension compared with the group [02] or the group [03] in each of which two units are registered. 
       FIG. 28  is a flowchart illustrating an example of a group integration operation internal process in Embodiment 2 of the present invention.  FIG. 29  is a diagram showing an example of group setting information at the time of deletion of indoor unit data of a basic group in Embodiment 2 of the present invention.  FIG. 30  is a diagram showing an example of group setting information at the time of registration of indoor unit data of an integrated group in Embodiment 2 of the present invention.  FIG. 31  is a diagram showing an example of group setting information at the time of re-registration of the indoor unit data of the integrated group in Embodiment 2 of the present invention.  FIG. 32  is a diagram showing an example of group setting information at the time of reallocation of group numbers in Embodiment 2 of the present invention. 
     (Step S 71 ) 
     The air conditioner managing console  2  determines whether the group number of the basic group, the group number of the joining group, and the group number not to be subjected to the integration process are acquired. If the group number of the basic group, the group number of the joining group, and the group number not to be subjected to the integration process are acquired, the air conditioner managing console  2  proceeds to step S 72 . On the other hand, if the group number of the basic group, the group number of the joining group, and the group number not to be subjected to the integration process are not acquired, the air conditioner managing console  2  returns to step S 71 . 
     (Step S 72 ) 
     The air conditioner managing console  2  deletes the address of the unit that is set in the joining group. 
     For example, as shown in  FIG. 29 , the addresses of the indoor units  4  that are included in the group [02] are deleted. 
     (Step S 73 ) 
     The air conditioner managing console  2  registers the address of the unit that is deleted from the joining group in the basic group. 
     For example, as shown in  FIG. 30 , the addresses of the indoor units  4  that are deleted from the group [02] are registered in the group [01]. 
     (Step S 74 ) 
     For each of the groups not to be subjected to the integration process, the air conditioner managing console  2  shifts the group number  70  by the number of the groups obtained by combining the basic group and the joining group, and registers the addresses of the units. 
     For example, as shown in  FIG. 31 , the address [005] and the address [006] of the indoor units  4  and the address [007] and the address [008] of the indoor units  4  are re-registered in the corresponding groups. 
     In the above description for step S 74 , the addresses of the indoor units  4  included in the groups that are not subjected to the division process are re-registered by shifting the group number  70 . However, the integration process is not particularly limited thereto. For example, as shown in  FIG. 32 , by shifting the group numbers  70 , an operation of reallocating the group numbers  70  may be executed instead of registering the addresses of the indoor units  4  included in the groups that are not subjected to the integration process. In this case, the air conditioner managing console  2  only needs to change the group number  70  for each of the group of m+1 and the subsequent groups to a number acquired by subtracting the number of the groups to be integrated from the group number  70 . 
     (Step S 75 ) 
     The air conditioner managing console  2  deletes the group in which no unit address is set, and ends the process. 
     (Advantageous Effects of Embodiment 2) 
     Due to the above description, in the case of executing the integration process, the air conditioner managing console  2  integrates the groups on the basis of the integration target, the integrated target, and the non-integrated targets, and displays each group icon button  80  with a size corresponding to the number of the indoor units  4  after re-registration. Thus, since the air conditioner managing console  2  is able to perform resetting of the groups by a simple operation based on the contents of work, the air conditioner managing console  2  is able to execute a group display corresponding to a layout change with less user burden. In addition, since the air conditioner managing console  2  changes the pixel dimension of each group icon button  80  in accordance with the result of the integration, misrecognition by a person in charge of work or the like is able to be prevented. 
     As described above, in Embodiment 2, the group number is assigned to each group. If the change command is an integration process for the groups, the CPU  16  integrates the association of the indoor units  4  associated with the groups on the basis of the group numbers and the contents of the integration of the groups, and causes icons to be displayed with display contents based on the integrated association of the indoor units  4 . 
     With the above configuration, by performing the integration setting of the groups by a simple operation based on the contents of integration, the air conditioner managing console  2  is able to perform a group display corresponding to a layout change occurring with the integration with less user burden. 
     Embodiment 3 
     Configuration of Embodiment 3 
       FIG. 33  is a diagram showing an example of group rearrangement in Embodiment 3 of the present invention. As shown in  FIG. 33 , the group [01] is rearranged from the head to the end. 
     (Operation of Embodiment 3) 
       FIG. 34  is a diagram schematically illustrating transition of a data structure occurring with group rearrangement in Embodiment 3 of the present invention. As shown in  FIG. 34 , on the premise of a state in which each group number  70  and a display position table including a display position are linked to each other, it is assumed that the display position included in the display position table is reallocated when the groups are rearranged. 
       FIG. 35  is a flowchart illustrating an example of a group rearrangement operation reception process in Embodiment 3 of the present invention.  FIG. 36  is a diagram showing an example of a layout screen  150   f  at the time of start of a group rearrangement operation before group rearrangement in Embodiment 3 of the present invention.  FIG. 37  is a diagram showing an example of a layout screen  150   g  after group rearrangement in Embodiment 3 of the present invention. 
     (Step S 91 ) 
     The air conditioner managing console  2  determines whether a group to be rearranged is selected. If a group to be rearranged is selected, the air conditioner managing console  2  proceeds to step S 92 . On the other hand, if a group to be rearranged is not selected, the air conditioner managing console  2  returns to step S 91 . 
     For example, as shown in  FIG. 36 , if the group icon button  81  for a rearrangement target is pressed by the physical object  171 , the air conditioner managing console  2  determines that a group to be rearranged is selected. At this time, the check mark  93  is displayed in the group icon button  85 , and the display color thereof is changed. 
     (Step S 92 ) 
     The air conditioner managing console  2  determines whether a rearrangement destination group is selected. If a rearrangement destination group is selected, the air conditioner managing console  2  ends the process. On the other hand, if a rearrangement destination group is not selected, the air conditioner managing console  2  returns to step S 92 . 
     (Step S 93 ) 
     For example, as shown in  FIG. 36 , if the group icon button  83  for an insertion destination is pressed by the physical object  171 , the air conditioner managing console  2  determines that a rearrangement destination group is selected. 
     As a result of the above, as shown in  FIG. 37 , the group icon button  81  is displayed at the right end which is the tail. Next, after a specified time period has elapsed from completion of the insertion, the check mark  93  becomes non-displayed in the group icon button  81 , and the display color thereof returns to the default state. 
       FIG. 38  is a flowchart illustrating an example of a group rearrangement operation internal process in Embodiment 3 of the present invention.  FIG. 39  is a diagram schematically illustrating a procedure of group rearrangement in Embodiment 3 of the present invention. 
     (Step S 101 ) 
     The air conditioner managing console  2  removes an insertion source group that is a rearrangement target. For example, this is shown with a label “a first state” in  FIG. 39 . 
     (Step S 102 ) 
     The air conditioner managing console  2  eliminates the space for the removed group icon button  80 . For example, this is a shown with a label “second state” in  FIG. 39 . 
     (Step S 103 ) 
     The air conditioner managing console  2  orderly arranges the group icon buttons  80  which are put closely. 
     (Step S 104 ) 
     The air conditioner managing console  2  inserts the insertion source group to the position of the insertion destination group. For example, this is shown with a label “a third state” in  FIG. 39 . 
     (Step S 105 ) 
     The air conditioner managing console  2  shifts the groups to the right by the space for the insertion source group. For example, this is shown with a label “a fourth state” in  FIG. 39 . 
     (Step S 106 ) 
     The air conditioner managing console  2  determines whether the right edge of the screen is crossed. If the right edge of the screen is crossed, the air conditioner managing console  2  proceeds to step S 107 . On the other hand, if the right edge of the screen is not crossed, the air conditioner managing console  2  ends the process. 
     (Step S 107 ) 
     The air conditioner managing console  2  displays the group icon button  80  that crosses the right edge of the screen at a lower stage, and ends the process. 
       FIG. 40  is a diagram showing a detailed example of positions in group rearrangement in Embodiment 3 of the present invention.  FIG. 41  is a diagram schematically illustrating an operation for rearranging a group from a current position to a left side in Embodiment 3 of the present invention.  FIG. 42  is a diagram schematically illustrating an operation for rearranging a group from a lower stage to an upper stage in Embodiment 3 of the present invention.  FIG. 43  is a diagram schematically illustrating an operation for rearranging a group from a current position to a right side in Embodiment 3 of the present invention.  FIG. 44  is a diagram schematically illustrating an operation for rearranging a group from an upper stage to a lower stage in Embodiment 3 of the present invention 
     For example, in an operation corresponding to No. 1 or No. 2, the group icon button  80  for the insertion destination is displayed at a position shifted backward by one as shown in  FIG. 41  or  FIG. 42 . In an operation corresponding to No. 3 or No. 4, the group icon button  80  for the insertion source is displayed at a position shifted frontward by one as shown in  FIG. 43  or  FIG. 44 . 
     (Advantageous Effects of Embodiment 3) 
     Due to the above description, merely by receiving a simple operation of the person in charge of work, the air conditioner managing console  2  is able to display the group icon buttons  80  in an orderly state where the group icon buttons  80  are automatically rearranged. 
     As described above, in Embodiment 3, the group number is assigned to each group. If the change command is a rearrangement process for the groups, the CPU  16  rearranges the association of the indoor units  4  to the groups, on the basis of the group numbers and the contents of the rearrangement of the groups, and causes icons to be displayed with display contents based on the rearranged association of the indoor units  4 . 
     With the above configuration, by performing the rearrangement setting of the groups by a simple operation based on the contents of rearrangement, the air conditioner managing console  2  is able to perform a group display corresponding to a layout change occurring with the rearrangement, with less user burden. 
     Embodiment 4 
     Configuration of Embodiment 4 
       FIG. 45  is a diagram showing an example of an association between a layout screen  150   h  and screen display position data in Embodiment 4 of the present invention. In  FIG. 45 , a setting in which the group icon buttons  80  are displayed in two rows and four columns is shown. For example, as display position information, [U1], [U2], [U3], and [U4] are allocated in order from left at the upper stage side, and [D1], [D2], [D3], and [D4] are allocated in order from left at the lower stage side. 
     (Operation of Embodiment 4) 
       FIG. 46  is a diagram showing an example of the screen display position data in Embodiment 4 of the present invention. As shown in  FIG. 46 , the group number data, the registered unit data, and the display position data are linked to each other. 
       FIG. 47  is a diagram showing an example of a communication command for display position designation in Embodiment 4 of the present invention. For example, the display position data is included in a communication command in order to keep the same arrangement sequence among each air conditioner managing console  2  after rearrangement. Specifically, a communication command including the address of a data transmission destination and display position data of a screen for each group is transmitted and received between the air conditioner managing consoles  2 , so that screen display information is shared by the air conditioner managing consoles  2 , and the air conditioner managing consoles  2  are allowed to be synchronized with each other for screen display position. 
       FIG. 48  is a flowchart illustrating an example of a communication process in Embodiment 4 of the present invention. 
     (Host Apparatus Screen Display Synchronization Process) 
     (Step S 121 ) 
     The air conditioner managing console  2   a  determines whether group rearrangement is executed. If group rearrangement is executed, the air conditioner managing console  2   a  proceeds to step S 122 . On the other hand, if group rearrangement is not executed, the air conditioner managing console  2   a  returns to step S 121 . 
     (Step S 122 ) 
     The air conditioner managing console  2   a  determines whether the other air conditioner managing console  2   b  is present within the same network. If the other air conditioner managing console  2   b  is present within the same network, the air conditioner managing console  2   a  proceeds to step S 123 . On the other hand, if the other air conditioner managing console  2   b  is not present within the same network, the air conditioner managing console  2   a  ends the process. 
     (Step S 123 ) 
     The air conditioner managing console  2   a  transmits the display position data to the other air conditioner managing console  2   b.    
     (Subordinate Apparatus Screen Display Synchronization Process) 
     (Step S 141 ) 
     The air conditioner managing console  2   b  determines whether the display position data is received. If display position data is received, the air conditioner managing console  2   b  proceeds to step S 142 . On the other hand, if the display position data is not received, the air conditioner managing console  2   b  returns to step S 141 . 
     (Step S 142 ) 
     The air conditioner managing console  2   b  rearranges the groups on the basis of the display position data. 
     (Step S 143 ) 
     The air conditioner managing console  2   b  displays the groups on the basis of the result of the rearrangement, and ends the process. 
     (Advantageous Effects of Embodiment 4) 
     Due to the above description, since the air conditioner managing consoles  2  are synchronized with each other for the display position of group icon buttons  80 , the air-conditioning system  1  is able to perform a group display corresponding to a layout change on each air conditioner managing console  2  included in the same network. 
     As described above, in Embodiment 4, the transmitting/receiving circuit  13  that transmits and receives various signals is further included, and the CPU  16  displays icons on the display unit  22  in an arrangement sequence corresponding to the indoor units  4  included in the groups. If various signals include an arrangement sequence, the arrangement sequence is transmitted via the transmitting/receiving circuit  13 . 
     In Embodiment 4, the air-conditioning system  1  includes a plurality of the air conditioner managing consoles  2 , each air conditioner managing console  2  transmits and receives a management signal to and from each other, and the management signal includes the display position of each icon. 
     With the above configuration, the air-conditioning system  1  is able to perform a group display corresponding to a layout change on each air conditioner managing console  2  included in the same network. 
     Embodiment 5 
     Outline of Embodiment 5 
     In Embodiment 5, the point will be described in which the air conditioner managing console  2  controls the above-described monitoring screen  31  to the display contents of a later-described monitoring screen  32 , and, for example, controls switching of presence/absence of display of the group numbers  70 . 
     (Operation of Embodiment 5) 
       FIG. 49  is a diagram showing an example of a group number display presence/absence setting screen in Embodiment 5 of the present invention. 
     As described above, in the case where group rearrangement is executed, a state is acquired in which the group numbers  70  are not in either ascending order or descending order, and thus the group icon button  81  to the group icon button  85  are not displayed in the order of group numbers. Here, the case is assumed where the user confirms the above-described monitoring screen  31  after the execution of group rearrangement. In the case of such an assumption, since the group icon button  81  to the group icon button  85  are not displayed in the order of group numbers, the user may make a false operation or misrecognition. That is, the monitoring screen  31  after group rearrangement can be a cause for a false operation and misrecognition by the user. Thus, in the case where group rearrangement is executed, the air conditioner managing console  2  causes the user to make setting of presence/absence of display of the group numbers  70 . 
       FIG. 50  is a diagram showing an example of the monitoring screen  32  at the time of setting absence of group number display in Embodiment 5 of the present invention. In each of the group icon button  81  to the group icon button  85 , the group number  70  is not displayed. 
     For example, if the user selects a “perform button  168 ”, the group numbers  70  are displayed as in the above-described monitoring screen  31 . On the other hand, if the user selects a “not perform button  169 ”, the group numbers  70  are not displayed in the group icon button  81  to the group icon button  85  as in the monitoring screen  32  shown in  FIG. 50 , unlike the above-described monitoring screen  31 . Such setting contents may be stored, for example, in the nonvolatile memory  15 . 
     (Advantageous Effects of Embodiment 5) 
     Due to the above description, the air conditioner managing console  2  is able to set the group numbers to be non-displayed, after a layout change, and thus is able to prevent a false operation and misrecognition by the user even in the case of a group display corresponding to a layout change. 
     As described above, in Embodiment 5, if the CPU  16  receives a display control signal concerning presence/absence of display of the group numbers, the CPU  16  controls whether to include the group numbers in the display contents of the icons in accordance with the display control signal. 
     With the above configuration, the air conditioner managing console  2  is able to prevent a false operation and misrecognition by the user even in the case of a group display corresponding to a layout change.
