When the number of connected units is 2 or more (S15: YE
S), the microcomputer 11 switches the initial screen and displays the selection screen on the display unit 13 (S16). At this time, on the displayed selection screen, as shown as an example in FIG. 8, a plurality of hot water heating terminals 2 to 4 to be operated are displayed in a list, and the recently operated heating terminal is the highest in the selection order. Is displayed. In the example of FIG. 8, the device names are sequentially displayed with characters such as “Japanese-style room”, “bathroom”, and “living room” corresponding to the installation location, and the devices can be selected in order from the top. That is, the user can first select the recently operated heating terminal, and stochastically, the more frequently used the heating terminal can be selected with a smaller number of operations. The portion selected by operating the up / down key 12A is highlighted. In addition, when there are terminals that cannot fit on one screen, all the terminals can be displayed by scrolling the selection screen by operating the up / down key 12A.

On the selection screen thus displayed, one desired heating terminal is selected, and when the user performs a display switching operation using one of the function switches 12C (S17: YES), the microcomputer 1
1 displays an operation screen for performing various operations on the selected heating terminal on the display unit 13 (S18). Then, the driving switch 12b is turned off to complete the display process. From the state in which the selection screen is displayed, it is possible to return to the display of the initial screen by performing a predetermined operation. The operation screens corresponding to the hot water heating terminals 2 to 4 are the same as the operation screens shown in FIGS. 5 and 6.

In S17, when the user does not perform the display switching operation (S17: NO), the microcomputer 11 returns to S16 and displays the selection screen as it is.

In S15, when there is only one connected device (S15: NO), the microcomputer 11
The process proceeds to S18 without displaying the selection screen, and the operation screen for one hot water heating terminal connected to the central remote controller 10 is displayed. That is, in this case, since it is not necessary for the user to select the operation target in the first place, the display of the selection screen is omitted, and the number of operations is reduced accordingly. If no heating terminal is connected to the centralized remote controller 10, only the initial screen is displayed.

When the user does not perform the display switching operation in S14 (S14: NO), the microcomputer 11 returns to S12 and displays the initial screen.

When the operation switch 12B is not turned on in S11 (S11: NO), the microcomputer 11 waits until the operation switch 12B is turned on.

Therefore, according to this embodiment as well, the same effect as that of the above-described embodiment can be obtained, and particularly when there is only one hot water heating terminal, the user does not need to perform a selection operation. , You can call the operation screen immediately from the initial screen.

The present invention is not limited to the above embodiment.

From the state in which the operation screen is displayed, an operation screen for performing more detailed operations through a predetermined operation may be displayed.

Regarding the order of displaying the operation screen and the order of displaying the list of heating terminals on the selection screen, the one operated at the time closest to the display time may be displayed at the top. Furthermore, the one with the largest number of operations may be displayed at the top.

When displaying an operation screen or a selection screen,
You may display in order of the connection apparatus which operation | movement started and / or operation | movement stopped by the reserved operation at the closest time. For example, at the current time of 9:00, there are a connected device (A) that started operating at 8:30 and a connected device (B) that stopped operating most recently (8:40) due to a reservation timer set with operation off. And In this case, on the operation screen and the selection screen, the connected devices (B) and (A) are displayed in this order.

Further, the following may be carried out. For example, when the current time is 9:00, the connected device (A) started to operate at 8:30, the connected device (B) in which the reservation timer was set so that the operation was turned off at 9:10, and the present time. It is assumed that there is a connected device (C) for which a reservation timer is set so that the operation is turned on at 9:20 during standby. In this case, the display order is ascending order of the absolute time difference with respect to the current time 9:00, that is, the absolute time difference is 10 each.
Minutes, 20 minutes, 30 minutes connected devices (B), (C),
The order is (A), and on the operation screen and the selection screen, the connected devices (B), (C), and (A) are displayed in this order.

The device name may be registered with characters freely decided by the user by combining the up / down key 12A and the function switch 12C.

The remote control device is not only applied as the centralized remote controller 10 in the hot water heating system, but may be, for example, the centralized remote controller in the hot water supply system.
