[0028]
FIG. 7 shows a daily timer program setting screen.
[0029]
In FIG. 7, the display of ten flags arranged side by side is a setting area A1 to A10, and is used for inputting operation setting change time and operation setting for performing automatic control. The setting areas A1 to A10 are arranged in time series from the setting area A1 to the setting area A10, and the CPU 51 sequentially performs automatic control in accordance with the contents set in the setting areas A1 to A10. Become. Each of the setting areas A1 to A10 includes a set time display area DT and an operation setting display area DM.
[0030]
The lower part of the display unit 2-2 includes a time input area TI and an operation setting input area MI for inputting operation settings.
[0031]
The operation setting input area MI includes an operation setting switch M1 for setting operation / stop by a touch panel method, a cooling / heating setting switch M2 for setting for switching between cooling operation / heating operation, and temperature setting for setting temperature. It comprises a switch M3, a wind speed setting switch M4 for setting the wind speed, and a remote control setting switch M5 for setting permission / prohibition of control by the remote controller. In this case, the operation setting switch M1, the cooling / heating setting switch M2, and the remote control setting switch M5 are in the form of a trigger switch. For example, each time the operation setting switch M1 is pressed, the operation is started and the operation is started. Stop can be selected. Further, the temperature setting switch M3 and the wind speed setting switch M4 display a switch corresponding to a display area of time setting switches HA, HB, MA, and MB described later, for example, a temperature setting switch, by pressing the switch.

[0034]
As shown in FIG. 7, on the setting screen of the first daily timer program, the setting area A1 is highlighted, and the setting time display area DT of the setting area A1 includes time setting switches HA, HB, MA, The same time (“09: 0AM” in the figure) as the time set using the MB (displayed in the time input area TI) is displayed. The operation display area DM displays that the operation (start) is performed by operating the operation setting switch M1.
[0035]
As a result, the operation is started at 9:00 am by confirming this setting with the confirmation switch EX.

Similarly, from the setting contents of the setting area A2, the set temperature is 24 [° C.] at 10:00 am.
[0037]
Hereinafter, similarly, control is performed based on the contents of the setting areas A3 to A10.
[0038]
Next, an outline operation of the air conditioning system will be described with reference to FIG.
[0039]
The CPU 51 of the control board 50 reads the daily timer program stored in the nonvolatile RAM 53, and performs the control specified in the daily timer program based on the internal timer.
[0040]
More specifically, as shown in FIG. 8 (a), for example, when the time designated by the daily timer program is 7:00 am, the first indoor unit 20-1 starts operation, and the second indoor unit If 20-2 is switching to the heating operation, the communication adapter 3-1 is notified via the interface unit 54 and the main communication line LM.
[0041]
Then, the communication adapter 3-1 adds address data representing the No. 1 indoor unit 20-1 and notifies the No. 1 indoor unit 20-1 of an operation start command via the sub communication line LS1. Similarly, the communication adapter 3-1 adds address data representing the No. 2 indoor unit 20-2, and notifies the No. 2 indoor unit 20-2 of a switching instruction to the heating operation via the sub communication line LS2.
[0042]
As a result, the CPU 30 of the No. 1 indoor unit 20-1 and the No. 2 indoor unit 20-2 respectively starts the operation and switches to the heating operation, and the remote controllers 20-1R and 20-2R “Run” and “Heating” are displayed, respectively.
[0043]
Thereafter, when the time becomes 2:00 pm, as shown in FIG. 8B, the time designated by the daily timer program is 2:00 pm, and the designated operation is the strong wind operation of the No. 1 indoor unit 20-1. Since the No. 2 indoor unit 20-2 is switched to the cooling operation, the communication adapter 3-1 is notified through the interface unit 54 and the main communication line LM.
[0044]
Then, the communication adapter 3-1 adds address data representing the No. 1 indoor unit 20-1 and notifies the No. 1 indoor unit 20-1 of the high wind operation start command via the sub communication line LS1. Similarly, the communication adapter 3-1 adds address data representing the No. 2 indoor unit 20-2, and notifies the No. 2 indoor unit 20-2 of a switching instruction to the cooling operation via the sub communication line LS 2.
[0045]
As a result, the CPU 30 of the No. 1 indoor unit 20-1 and the No. 2 indoor unit 20-2 starts the strong wind operation and switches to the cooling operation, respectively, and the remote controllers 20-1R and 20-2R. In addition, “strong wind” and “cooling” are displayed, respectively.
[0046]
As described above, according to this embodiment, an arbitrary operation command can be sent to an arbitrary indoor unit at an arbitrary time, and automatic control can be performed for each indoor unit.
[0047]
Although description of specific embodiment is finished above, the aspect of the present invention is not limited to the above embodiment. For example, in the above embodiment, the operation setting change time and the operation setting content are input by the touch panel method, but the input unit and the display unit may be separated, and other device configurations, setting procedures, etc. In the range which does not deviate from the meaning of the present invention, it can change suitably.
[0048]
【The invention's effect】
According to the first aspect of the present invention, the data storage means stores the operation setting at a predetermined time during operation of each controlled device input by the input means as the operation setting data together with the predetermined time, and the data display means When the operation setting data is input by the input means, the input state is displayed in time series, and the operation control means causes the controlled apparatus to perform an operation based on the operation setting data. Therefore, it is possible to operate with a desired operation setting at a desired time. That is, not only the operation / stop control but also control such as cooling / heating switching, room temperature setting, wind speed setting, and remote control prohibition can be performed at a desired time.
Furthermore, since the data display means displays the input state of the operation setting data in time series when the operation setting data is input by the input means, it is possible to reduce input errors at the time of data input and to reliably control the control state. I can grasp it.
[0049]
According to the invention of claim 2, the centralized control device connected to the plurality of controlled devices via the communication line causes the controlled device to operate based on the operation setting data stored in the data storage means. When the operation setting data is input by the input means in advance, the data display means displays the input state of the operation setting data in time series when the operation setting data is input by the input means, thereby reducing input errors at the time of data input. It is possible to grasp the control state with certainty.
Furthermore, since the operation control means causes the controlled device to perform an operation based on the operation setting data, each controlled device can be individually operated at a desired time and with a desired operation setting. That is, not only the operation / stop control but also control such as cooling / heating switching, room temperature setting, wind speed setting, and remote control prohibition can be performed at a desired time.
[0050]
According to the invention of claim 3, the inputted operation setting at a predetermined time during operation of each controlled device is stored in the storage unit together with the predetermined time, and the operation setting is performed on the display unit when data is input by the data input unit. Since the data input state is displayed in time series and the controlled device is operated based on the operation setting data, each controlled device can be individually operated at a desired time and with a desired operation setting. That is, not only the operation / stop control but also control such as cooling / heating switching, room temperature setting, wind speed setting, and remote control prohibition can be performed at a desired time.
