A hot water supply apparatus A is capable of hot water supply to a bathtub 17 and reheating by forced circulation of bathtub water. it can. The water heater A is operated and operated by a controller 21 arranged everywhere.

Water is supplied to the water heater A from the water inlet, and the flow of water is detected by a water amount sensor 4 as operation performance detecting means. The water passes through a water input thermistor 5 and is heated by a heat exchanger 6 for hot water supply. It becomes hot water. After passing through the hot water supply thermistor 7, the hot water becomes a constant water quantity by the water quantity proportional valve 8. The gas proportional valve 10 is driven and adjusted so that the hot water supply temperature is set to, for example, the incoming water temperature plus 2 ° C.). Then, the hot water that has passed through the automatic hot water supply electromagnetic valve 11 passes through the bath water flow switch 12, the bath thermistor 13, and the heat exchanger 14 for the bath, and reaches the bathtub 17 from the outlet 15 via the bath adapter 16. During this operation, when the two-way valve 18 is opened (there are two states of “open” and “closed”), the hot water flows into the bathtub 17 also from the return port 19. The hot water is supplied to the set amount set by the automatic hot water supply amount setting means 20 (in the test operation mode, the set amount is set to an amount smaller than the normal minimum value in order to shorten the hot water supply time). Operation ends.

The electrical unit 1 for controlling the water heater A starts the trial operation mode when the connector 3 is inserted into the connector pin 2a as the trial operation means, and instructs switching from the trial operation mode to the normal operation mode when the connector 3 is replaced with the connector pin 2b. . Hot water supply thermistor 7 as operation performance detection means, flame sensors 22 and 23 for detecting the combustion state of burner
And the like, and control means 24 for receiving the input signal from the controller and the like to perform heating control, combustion control, hot water supply temperature control, and the like, and abnormality determination means 25 for determining whether the operation state is good or not. The controller 21 has an automatic hot water supply setting means 20 for setting the amount of hot water in the bathtub 17, a bath temperature setting means 9 for setting the hot water temperature, and a code number for the cause of the abnormality when the operation performance is abnormal during the normal operation mode and the test operation mode. An indicator 26 having a 7-segment LED as a means for notifying the cause of abnormality to be displayed and a means for notifying an operation state in the test operation mode, an operation switch 27 for instructing a normal operation, and a notification buzzer 28 for notification are provided.

Next, a description will be given of the test operation based on the above configuration. In the test operation mode, the connector 3 (which is initially included in the connector pin 2b ) is replaced by the connector pin 2a on the electrical unit 1; Start. Then, according to the sequence of the test operation mode set in the control means 24, the automatic hot water supply operation is performed first, and when the operation is normally completed, the test operation sequence provided in the appliance is sequentially performed, such as performing the reheating operation. To go. The abnormality determining means 25 checks the input signal of the driving performance detecting means for each of these various test operation sequences to determine whether there is any abnormality, and if there is an abnormality, instructs the control means 24 to stop the operation. The display 26 blinks the cause of the abnormality determined from the input signal by code number. Only at the time of occurrence of this abnormality, the notification buzzer 28 notifies the abnormality as sound.

During the operation of the test operation mode, various actuators such as the water proportional valve 8 are operated, and a large number of complicated
Since the movements are executed sequentially , it takes some time until one test run is completed even if the settings are reasonable. Therefore, during normal operation, a sequence number indicating the operation state of the test operation is displayed on the display means so that the installer can easily understand the operation state of the appliance. FIG. 2 is a flowchart of the test operation mode for reference. If an abnormal stop occurs for some reason during the test operation, a corresponding display is displayed. For example, if the bath pump is abnormal,
The corresponding error code number is displayed (a voice indicating which part of the appliance should be repaired, or a liquid crystal display may be used).

When the test operation is completed normally, a display indicating the end of the test operation is displayed on the display 26, and a notice buzzer 28 continuously informs the enforcer who waits for the end of the test operation. Then, the notification sound is muted when the connector 3 is replaced with the connector pin 2a from the connector pin 2b, the end of the trial operation mode is instructed, and the normal operation mode is put on standby. For this reason, the end of the test run can be notified to the enforcer in a timely manner, and the forgetting to switch the operation mode can be automatically prevented.

When the test operation mode is completed and the normal operation is started next, the operation switch 27 is turned on to perform a required setting operation, open the hot water tap B or the like, and perform the hot water supply operation or the bathtub 17.
