[0020]
Next, in step 51, the hot water temperature setting change, that is, the hot water temperature display displayed on the dot matrix type display 31 is added or subtracted once, and further, a beep sound "bit" is transmitted to confirm acceptance, The setting timer 46 starts counting for 1 second.
[0021]
Further, the process proceeds to step 52 to determine whether or not the temperature setting switch 41 is operated again. When the operation is YES, the process proceeds to step 53, and further the hot water temperature setting change and the beep sound and the count of the setting timer 46 are cleared. After that, counting is started again.
[0022]
If NO, the process proceeds to step 54 and waits for the setting timer 46 to count up for 1 second. If YES, that is, it is determined that the setting change operation is completed, the process proceeds to step 55 and the second storage unit 47 stores The current hot water temperature setting K is stored.
[0023]
Then, the process proceeds to step 56, where “=” is used to determine whether there is a difference between the set temperature T stored in the first storage unit 45 by the comparison unit 48 and the set temperature K stored in the second storage unit 47. If it is confirmed that YES, i.e., it has not been changed, the voice guidance is not performed and the process ends in step 57, and the voice guidance is not performed even if the setting is mistakenly changed and then returned to the original state as before.
[0024]
If it is changed but not the same, the process proceeds to step 58 if NO, and it is determined whether the set temperature K after the change is equal to or higher than the predetermined value of 60 ° C. The control unit 33 outputs voice data indicating that the setting has been changed, and a voice guide that “the hot water supply temperature has been changed” is performed from the speaker 34 via the amplifier 35.
[0025]
If YES at 60 ° C or higher, the process proceeds to step 60, and the voice guidance for alerting you to "hot water is out" is performed in the same way. It is sent to the main body side control device 2 via the communication controllers 23a and 23b, and hot water supply is controlled according to this temperature.
[0026]
Therefore, after confirming the change of the setting once, the user is informed that the setting has been changed by voice guidance only when the change is surely performed. It is reliable and can be used with peace of mind, and when it is changed to 60 ° C or higher, it is guided by a different voice guide that it is dangerous at high temperatures, so it has a more alert action and can prevent danger It is.
[0027]
In this embodiment, the hot water supply temperature setting has been described as an example. However, the present invention is not limited to this, and of course, for example, a bath temperature setting or a bath water amount setting may be used.
[0028]
【The invention's effect】
As described above, according to the present invention, the setting value before the setting change is compared with the setting value after the setting change, and the voice guidance is performed only when there is a difference. When the setting is changed by mistake and changed back to the original setting as in the past, the voice guidance is not performed, and it is easy to use and reliable and can be used with peace of mind.
[0029]
Furthermore, when there is a difference more than a predetermined value, the voice guide that calls attention is changed, so that the dangerous state can be easily avoided and can be used with confidence.
