In recent years, due to the liberalization of electric power, the electricity rate system of electric power companies has changed and diversified. In addition, various methods are required for the boiling operation method of the hot water storage type hot water supply device 100, such as the subsidy system of a public institution is applied depending on the boiling operation method. The boiling operation method is, for example, how to control the start time and end time of the boiling operation, the boiling temperature, the amount of hot water stored in the hot water storage tank 1, and the like.

In the present embodiment, by changing the control program executed by the water heater control unit 24 to a different version of the control program, it is possible to correspond to various boiling operation methods. For this reason, it is possible to respond to changes and diversification of the electricity rate system of the electric power company and to respond to the subsidy system of a public institution while suppressing the production cost of the hot water storage type hot water supply device 100. The version information of the control program is hereinafter referred to as "version information".

The control program stored in the water heater control unit 24 has its own version information. The water heater control unit 24 can transmit the version information to the remote controller 25.

Whether or not the energization control discount, which is the electricity rate discount system of the electric power company, is applied is determined by the method of boiling the hot water storage type hot water supply device 100. For this reason, conventionally, when constructing the hot water storage type hot water supply device 100, it has been performed to apply for the model name to the electric power company. In the future, due to changes and diversification of the electricity rate system of electric power companies, or the application of subsidy systems of public institutions, we will apply for the model name to the electric power company or public institutions when constructing the hot water storage type hot water supply device 100. It is expected that the number of cases will increase. Further, even in the hot water storage type hot water supply device 100 of the same model, the boiling operation method differs depending on the version of the control program executed by the hot water heater control unit 24. Therefore, it is expected that it will be necessary to apply not only to the model name of the hot water storage type hot water supply device 100 but also to the version information of the control program of the water heater control unit 24 to the electric power company or a public institution. .. Therefore, when it is necessary to apply for the version information of the control program of the water heater control unit 24 to the electric power company or a public institution, such as when constructing the hot water storage type hot water supply device 100, the contractor or the like applies the version information. If it can be easily known, the convenience will be good.

When the construction of the hot water storage type hot water supply device 100 is completed, the contractor or the like turns on the power of the hot water storage type hot water supply device 100. The hot water storage type hot water supply device 100 according to the present embodiment displays the version information of the control program stored in the water heater control unit 24 on the display unit 25a when the power supply of the hot water storage type hot water supply device 100 is switched from off to on. It is configured in. Therefore, when the power of the hot water storage type hot water supply device 100 is turned on, the version information is automatically displayed on the display unit 25a, so that the contractor or the like can easily obtain the version information without requiring any special operation. Can be confirmed in. Therefore, excellent convenience can be obtained when applying for version information to an electric power company or a public institution.

In the present embodiment, the control program executed by the remote control unit 25c may be changed to a different version of the control program. In that case, the following may be performed. The control program stored in the remote control unit 25c has its own version information. When the version information of the control program of the water heater control unit 24 is displayed on the display unit 25a, the version information of the control program of the remote control unit 25c may also be displayed. Alternatively, only the version information of the control program of the remote control unit 25c may be displayed.

Hereinafter, the matters relating to the control program of the water heater control unit 24 will be mainly described, but the same matters may be applied to the control program of the remote control unit 25c. Further, in the following description, when the term "control program" is simply used, in principle, at least one of the control program of the water heater control unit 24 and the control program of the remote control unit 25c is included. Further, when simply referred to as "version information", as a general rule, it is information including at least one of the version information of the control program of the water heater control unit 24 and the version information of the control program of the remote control unit 25c. And.

FIG. 2 is a flowchart of the control operation of the hot water storage type hot water supply device 100 according to the first embodiment. In step S1 of FIG. 2, the water heater control unit 24 determines whether or not the power of the hot water storage type hot water supply device 100 is turned on. When the power is turned on, that is, when the power is switched from off to on, the process proceeds to step S2, and the water heater control unit 24 outputs the version information of the control program stored in its own memory to the remote control control unit. Send to 25c. The version information may include letters and numbers, such as "v0100", or may contain only letters or numbers.

From step S2 to step S3, the remote control control unit 25c displays the version information received from the water heater control unit 24 on the display unit 25a. Subsequently, in step S4, the remote control control unit 25c determines whether or not a predetermined time has elapsed since the version information was displayed on the display unit 25a. The predetermined time may be, for example, 10 minutes. When the predetermined time has elapsed, the process proceeds to step S5, and the remote control control unit 25c hides the display of the version information by the display unit 25a and ends the display of the version information.

As described above, in the present embodiment, when applying the version information of the control program to the electric power company or a public institution at the time of construction of the hot water storage type hot water supply device 100, a special case for confirming the version information. The version information can be known from the display unit 25a without the need for the operation of. Therefore, excellent convenience can be obtained. Moreover, since no special operation is required to display the version information of the control program, it is possible to suppress an increase in cost due to the addition of the number of parts for the operation.

The contractor usually applies for version information to an electric power company or a public institution. Therefore, the end user does not need version information. In the present embodiment, when the version information is displayed on the display unit 25a, the display of the version information on the display unit 25a is automatically terminated when a predetermined time elapses. Therefore, the contractor does not need to perform an operation of ending the display of the version information of the display unit 25a, which is convenient. In addition, it is possible to reliably prevent the hot water storage type hot water supply device 100 from being handed over to the end user in a state where version information unnecessary for the end user is displayed on the display unit 25a.

Instead of the processes of steps S4 and S5 of FIG. 2, the following may be performed. When the version information is displayed on the display unit 25a, the remote control control unit 25c continues to display the version information of the display unit 25a until the operation unit 25b is operated, and when the operation unit 25b is operated, the display unit 25c continues to display the version information. The display of the version information of 25a may be terminated. By doing so, there is an advantage that the display of the version information is not automatically terminated before the contractor or the like confirms the display of the version information of the display unit 25a. In this case, the contractor or the like can end the display of the version information of the display unit 25a by operating the operation unit 25b after confirming the display of the version information of the display unit 25a. Therefore, it is possible to reliably prevent the hot water storage type hot water supply device 100 from being handed over to the end user while the version information unnecessary for the end user is displayed on the display unit 25a.

When a plurality of control programs having different versions are stored in the water heater control unit 24 and are configured so that the control program to be used can be selected from the plurality of control programs, the plurality of control programs can be selected. Of these, it is desirable to display the version information of the selected control program on the display unit 25a.

The water heater control unit 24 may have a plurality of control modes in which the boiling operation method is different. Then, the hot water storage type hot water supply device 100 can accept an operation of selecting and setting a control mode corresponding to a contract with an electric power company from the plurality of control modes as a control mode for boiling operation. It may be configured. The operation is hereinafter referred to as "boiling operation mode setting operation". For example, by operating the operation unit 25b of the remote controller 25, the boiling operation mode setting operation may be performed.

The hot water storage type hot water supply device 100 may be configured to display version information on the display unit 25a when the boiling operation mode setting operation is performed. Thereby, at the time of construction of the hot water storage type hot water supply device 100, the version information can be easily confirmed while performing the boiling operation mode setting operation. Therefore, when applying for version information to an electric power company or a public institution, it is possible to obtain a convenient hot water storage type hot water supply device 100 without requiring a special operation for confirming the version information.

In addition, when applying for version information to an electric power company or a public institution, a contractor or the like needs to perform a boiling operation mode setting operation in order to confirm the version information. Therefore, it is possible to surely prevent the contractor or the like from forgetting to perform the boiling operation mode setting operation at the time of construction.

The control program stored in the water heater control unit 24 or the control program stored in the remote control unit 25c may be configured to be rewritten with another version of the control program. For example, by connecting a computer having a program rewriting tool (not shown) to the water heater control unit 24 or the remote control unit 25c, a control program stored in the memory of the water heater control unit 24 or the remote control unit 25c can be stored. It may be rewritten. Further, the water heater control unit 24 or the remote control unit 25c may be configured so that the control program can be rewritten by acquiring another version of the control program from an external server via a network such as the Internet. By doing so, even if there is an addition or change in the electricity rate system of the electric power company or the subsidy system of the public institution, the user can obtain the corresponding control program from the Internet etc. You can apply for version information of this control program. This allows them to benefit from additional or modified utility electricity tariffs or public sector subsidies without having to purchase products with new control programs stored. In the following description, the operation of rewriting the control program to another version of the control program is referred to as a "program rewriting operation".

Further, a plurality of control programs having different boiling operation methods are stored in the memory of the water heater control unit 24, and for example, by operating the remote controller 25, the control program to be used from among the plurality of control programs, that is, It may be configured so that the control program executed by the processor of the water heater control unit 24 can be selected. In the following description, the operation of selecting one of the plurality of control programs having different versions in this way is referred to as a "program selection operation". Further, the control program of the remote control unit 25c may be configured so that the program selection operation can be performed. For example, a plurality of control programs corresponding to different methods of boiling operation are stored in the memory of the remote controller control unit 25c, and for example, by operating the remote controller 25, a control program to be used from among the plurality of control programs is used. That is, it may be configured so that the control program executed by the processor of the remote control unit 25c can be selected.

After the operation of the hot water storage type hot water supply device 100 is started, the program rewriting operation or the program selection operation may be performed. By doing so, after the operation of the hot water storage type hot water supply device 100 is started, it is possible to respond to changes and diversification of the electricity rate system of the electric power company, and to respond to changes in the subsidy system of public institutions. It becomes possible.

The hot water storage type hot water supply device 100 is configured to display the version information of the rewritten control program or the version information of the selected control program on the display unit 25a when the program rewriting operation or the program selection operation is performed. You may. To confirm the version information when applying for the version information to an electric power company or a public institution by automatically displaying the version information on the display unit 25a when the program rewriting operation or the program selection operation is performed. Since no special operation is required, it is possible to obtain a convenient hot water storage type hot water supply device 100. Further, after the version information is displayed on the display unit 25a, the display of the version information is automatically terminated when a predetermined time elapses, or the operation unit 25b is waited to be operated in the same manner as described above. You may end the display of version information.

The version information may be displayed on the display unit 25a by a bar code or a two-dimensional code. As a result, when applying for version information to an electric power company or a public institution, the barcode or two-dimensional code is read by the camera of the mobile communication terminal owned by the contractor, etc., and data transmission using the network is used. It will be possible to apply. As a result, it is possible to surely prevent the contractor or the like from misreading the display of the version information. The two-dimensional code may be, for example, a QR code (the QR code is a registered trademark).

When the version information is displayed on the display unit 25a, the model name and serial number of the hot water storage type hot water supply device 100 may be displayed together with the display unit 25a. As a result, when applying for information on the hot water storage type hot water supply device 100 to an electric power company or a public institution, it is possible to more reliably prevent a shortage of necessary information.

When the version information is displayed on the display unit 25a, the operation specification information of the hot water storage type hot water supply device 100 may be displayed together with the display unit 25a. The operation specification information is information that is expected to require an application to an electric power company or a public institution. For example, the start time of boiling operation such as "boiling control time zone: 23:00 to 7:00". And information indicating the end time may be used. By displaying the operation specification information together with the version information on the display unit 25a, the contractor, etc. operates by checking the instruction manual when applying for the information of the hot water storage type hot water supply device 100 to the electric power company or a public institution.
