  By the way, when installing the hot water supply device, it is necessary to store various settings indispensable for the hot water supply device to operate. In addition, if the hot water supply apparatus is operated immediately after installation, the air layer accumulated in the piping has caused problems such as prolonged operation time and markedly deteriorated heating efficiency. Therefore, it is necessary to check the operation performance of the hot water supply device by always venting the air before the operation and performing a boiling test operation on the air.

  Usually, the installation of hot water supply equipment is performed by workers such as electrical contractors and construction contractors, but there are cases where multiple workers are replaced and are in charge of the installation, which is indispensable before the operation of the hot water supply equipment. It is easy to forget various settings, air venting, and trial operation.

  As a result, the user suffers damage such as slow operation time of the hot water supply device, poor heating efficiency and running out of hot water in the hot water storage tank after a while.

In order to solve the conventional problems, a remote controller for a hot water supply apparatus of the present invention includes a panel unit for displaying a setting selection screen for inputting a setting confirmation item at the time of a trial operation of the hot water supply apparatus, and a setting in the setting selection screen. An operation unit for inputting a confirmation item, a control unit for preferentially displaying the setting selection screen on the panel unit when the power supply of the hot water supply device is first turned on, and a storage unit for storing the input status of the setting confirmation item In the trial operation of the hot water supply device, a test operation is performed according to the confirmation items on the setting selection screen, and the confirmation items include items of “air removal work” and “boiling trial operation”, and after the “air removal work” is completed Even if the power supply stops while setting the confirmation item, the setting confirmation item that has not been entered will be displayed before the next startup. By displaying the panel unit and performing a trial run, essential setting and works like becomes a cause of failure to be performed during construction or during re-installation of the water heater (e.g., time setting Ya It is possible to reliably alert the operator to the registration of the electricity billing system and the evacuation of the pipes, and to prevent malfunctions and malfunctions of the water heater. In addition, the heating operation cannot be performed unless the necessary setting and the setting of work are completed.

  The remote controller for a hot water supply apparatus of the present invention urges an operator, such as a construction worker, to perform an accurate work at the time of construction / installation of the hot water supply apparatus, and prevents a malfunction or malfunction of the hot water supply apparatus in advance. Can be suppressed.

1st invention is a panel part which displays the setting selection screen for inputting the setting confirmation item at the time of the trial run of a hot water supply apparatus, the operation part which inputs the setting confirmation item in the said setting selection screen, The said hot water supply apparatus Control means for preferentially displaying the setting selection screen on the panel unit when power is first turned on, and storage means for storing an input status of the setting confirmation item, and during the trial operation of the water heater, the setting selection screen A test run is performed in accordance with the check items in the above, and the check items include the items “Bleeding work” and “Boil-up test run”, and the item “Boil-up test run” is displayed after the “Bleeding work” is completed. configured, the even when the check item stops power supply during the configuration, the next startup, and performing a trial run to display the setting confirmation item has not been inputted to the panel portion Hot water is a device for the remote control.

  This ensures that the operator is alerted to essential work (for example, venting air inside the pipe) that would cause failure if the hot water supply device is not installed or re-installed. Can be suppressed.

Further, the setting confirmation item includes execution of control (air venting) for venting air in the pipe of the hot water supply apparatus. The air venting operation is one of the operations forgotten especially during construction. In addition, a hot water supply apparatus that is not performing the air venting operation is one of the failures in which the influence is difficult to be confirmed from the appearance and the cause is difficult to identify, for example, the boiling rate becomes slow after a certain period of time during construction. Therefore, if the execution of the air venting operation is cited as the setting confirmation item, the air venting operation is surely performed at the time of installation, and failure of the hot water supply apparatus can be suppressed.

In principle, all operation settings are entered when the power is turned on for the first time. However, the operator may postpone the settings arbitrarily or leave it blank for reasons such as shortening the work time or taking over the workers. Can do. However, even if it is not input at the first power-on, the operator may forget to input after that. Thus, by displaying the setting confirmation items that have not been input each time the power is turned on, the operator can surely input without forgetting.

  As described above, for example, if the hot water supply apparatus performs a boiling operation without performing the air venting operation, it causes a failure. Therefore, by preventing the boiling operation from being performed until the input of the setting confirmation item (for example, the air venting operation) is completed, the operator performs the air heating operation after the air venting operation has been performed, and the occurrence of a later failure. Can be suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows an external view of a remote controller for a hot water supply apparatus according to the first embodiment of the present invention, and FIG. 2 shows a configuration diagram of the remote controller for a hot water supply apparatus.

  As shown in FIG. 1, a remote controller 101 for a hot water supply device includes a panel unit 102 that displays a boiling temperature setting value, time, amount of hot water in a bathtub, and the like, and a menu switch that calls a setting screen when setting the time or setting the remote control itself. 103, a selection switch 104 for selecting a specific setting confirmation item from the options displayed on the panel unit 102, and a confirmation switch 105 for confirming the setting confirmation item selected by the selection switch 104.

  In addition, as shown in FIG. 2, the remote controller for hot water supply apparatus 101 includes a control unit 201 that controls display contents of the panel unit 102, information for displaying on the panel unit 102, set values and time of the hot water supply device, and the like. A storage unit 202 for storing and an input unit 203 for inputting a set value of the hot water supply device are provided. Note that the input unit 203 includes a selection switch 104 and a confirmation switch 105.

  The set value of the hot water supply device stored in the storage unit 202 can be illustrated as shown in FIG. 3, for example. According to FIG. 3, the setting confirmation item 301 is a confirmation item “whether the hot water storage tank is full at the time of installation”, and it is indicated that the setting confirmation item has been input. Further, the setting confirmation item 302 is a confirmation item “whether or not to perform air venting”, and indicates that the setting confirmation item is not input. The setting confirmation item 303 is a setting item of “setting of electric power charge system”, and indicates that the setting confirmation item has been input. Further, the setting confirmation item 304 is a confirmation item “whether or not to perform the boiling trial run”, and indicates that the setting confirmation item has been input.

  The operation and action of the hot water supply remote controller 101 configured as described above will be described below.

  First, when the power is turned on for the first time after an operator installs the hot water supply device, the power is also supplied to the hot water supply remote controller 101. At this time, the control unit 201 first confirms the contents of the storage unit 202. When the power is turned on for the first time, all the setting confirmation values of the hot water supply device stored in the storage unit 202 are not input. Therefore, when the power is first turned on, the control unit 201 displays the setting confirmation items that have not been input on the panel unit 102 so as to be included in the setting selection screen 501 as shown in FIG.

  In FIG. 4, in the setting selection screen 501, the setting confirmation item 302 “whether to perform air venting”, the setting confirmation item 303 “setting of the electric power charge system”, and the setting confirmation item 304 “execute boiling test run” are performed. The operator confirms and inputs each message. The flow of input will be described in detail. For example, when the operator desires to perform air bleeding in response to the message “whether to perform air bleeding” of the setting confirmation item 302, the operator presses the confirmation switch 105. Then, the pump of the hot water supply device is activated and the air in the pipe is extracted. When the air venting operation is completed, other setting confirmation items stored in the storage unit 202 are displayed. Thereafter, a message “whether or not to perform the boiling test run” of the setting confirmation item 304 is displayed. If the setting confirmation item is not always displayed after the setting confirmation item “whether or not to perform air venting”, the boiling operation is performed before the air is vented. It is displayed for all setting confirmation items and continues until the input is completed.

  When the input is completed and the setting selection screen 501 is no longer displayed from the panel unit 102, the worker (or the user) can perform the boiling operation from that point. That is, while the setting selection screen 501 is displayed and the operator confirms and inputs the setting confirmation item, a request for the heating operation is not accepted. Therefore, the boiling operation is not performed before the operator (or the user) vents the air, and the malfunction or malfunction of the hot water supply apparatus can be suppressed.

  In this way, the setting contents of the setting confirmation items are displayed on the panel unit 102 for the operator at the time of installation, so that the user can be alerted, and the setting and necessary work can be performed without forgetting, so that the failure of the hot water supply device can be performed in advance. Can be suppressed.

(Embodiment 2)
In the first embodiment, the boiling operation can be performed after all the setting confirmation items have been input and completed after the power is first turned on. By the way, assuming that a power failure or the like occurs during setting and the power is not supplied, not all setting confirmation items are always input. In addition, it takes 10 to 30 minutes for the air venting work. If it is unavoidable that the work time is unavoidable, the setting is skipped as no entry, and other setting confirmation items are entered first to finish the input work. can do. For example, it can be implemented by a design such as providing an input skip switch in the hot water supply remote controller 101. Alternatively, it may be possible to implement by a special operation such as continuously pressing the confirmation switch 105 for several seconds without providing a switch.

  Therefore, in the second embodiment, in consideration of the above-described problems, and in order to prevent the possibility that the operator forgets to input items that have not been input, the control unit 201 is not yet turned on at the next energization activation of the hot water supply remote controller 101. Only the setting confirmation item that is an input is displayed on the panel unit 102 so as to be included in the setting selection screen 501.

  As described above, the uninput items are displayed again when the power is turned on, so that the operator can surely input without forgetting.

In particular, when the air venting operation and the boiling trial operation, which are important operations, are not performed, the user is prompted again to suppress the failure of the water heater.

  As described above, the remote controller for a hot water supply apparatus according to the present invention can be applied as a remote controller for an electric hot water supply apparatus and a gas hot water supply apparatus in addition to a heat pump hot water supply apparatus.
