There is a risk of burns. Therefore, from the viewpoint of ensuring safety, it may be desirable to restrict the hot water supply temperature range that can be set from the remote controller so that hot water cannot be supplied at a temperature higher than a predetermined temperature (for example, the hot water supply temperature range is 37 When it is set to -60 ° C, it is preferable to change this range to about 37 to 42 ° C from the viewpoint of preventing burns).

On the other hand, considering various usage modes of the hot water supply apparatus, it is not prohibited to set a high temperature exceeding a preset hot water supply temperature range from the remote controller, and the degree of freedom in selecting the hot water supply temperature range is increased. It may be desirable to make it larger.

It is comprised including.

In the above hot water supply apparatus, a setting condition change mode, which is a mode in which the hot water supply temperature range that can be set by the remote controller 20 is changed, can be selected from the remote controller 20 side. The remote controller 20
Is operated to enter the setting condition change mode, the hot water supply temperature range can be arbitrarily changed from the remote controller 20.

Next, in the hot water supply apparatus configured as described above, the operation mode when changing the hot water supply temperature range that can be set from the remote controller 20 will be described.

[Operation Mode 1] As shown in the flow chart of FIG. 2, first, the remote controller 20 is operated to enter a setting condition changing mode (for example, a maintenance mode) capable of changing the hot water supply temperature range (step 1). .

Next, it is judged (selected) which of the upper limit value and the lower limit value is to be changed (step 2),
In the case of the mode for changing the upper limit value, the upper limit value data is changed by the operation means 23 of the remote controller 20 (step 3), and in the case of the mode for changing the lower limit value, the operation means of the remote controller 20. The lower limit data is changed by 23 (step 4), and the change of data is completed (step 5).

Then, the upper limit value and the lower limit value data are determined by the operation means 23 to determine the data (step 6). Then, when the data is determined, the ROM 22 of the remote controller 20 stores the new data, and the upper limit value data and the lower limit value data are rewritten (step 7).

In the hot water supply apparatus described above, since the hot water supply temperature range can be changed from the remote controller 20 on condition that the setting condition changing mode is entered, safety is impaired. Without
It is possible to easily change the hot water supply temperature range from the remote controller 20.

[Operation Mode 2] As shown in the flow chart of FIG. 3, temperature range changing means 13 for changing the upper and lower limits of the hot water supply temperature range of the burner controller 10a.
(For example, a dip switch) was operated to change the upper limit value and the lower limit value of the hot water supply temperature range (step 11).
Then, the data change is confirmed (step 12).

Then, from the communication means 12 on the burner controller 10a side, change data of the upper limit value and the lower limit value are transmitted to the remote controller 20 side (step 13),
This is received by the communication means 21 on the remote controller 20 side (step 14).

Then, the data received by the communication means 21 is stored in the ROM 22 of the remote controller 20,
The upper and lower limit data are rewritten (step 1
5).

In this way, the burner controller 10
Since it is possible to change the hot water supply temperature range from the remote controller 20 on condition that the temperature range changing means 13 of a is operated, the remote controller 20 can easily change the hot water supply temperature without impairing safety. You can change the range.

The burner controller 10 is used here.
The case has been described in which the temperature range changing means 13 of a is operated to change the upper limit value and the lower limit value of the hot water supply temperature range, and this is transferred to the remote controller.
As the hot water supply temperature range that can be changed by the remote controller 20, by transferring data preset in the burner controller 10a of the water heater main body 10 to the remote controller 20 side, the upper limit value and the lower limit value of the hot water supply temperature range can be set from the remote controller 20. It can also be configured to be changeable.

[Operation Mode 3] In this operation mode, when hot water cannot be supplied at the hot water set temperature set by the remote controller 20 due to the performance of the water heater main body 10 and the environment in which it is used (for example, by the remote controller). This is an operation mode when hot water cannot be supplied at a lower limit that can be set).

As shown in the flowchart of FIG. 4, when the burner controller 10a determines that hot water cannot be supplied at the hot water supply set temperature set by the remote controller 20, the voice output means (warning means) 25 gives an alarm. When a sound is generated, the burner controller 10a changes the data of the upper limit value and the lower limit value of the hot water supply temperature range (step 21), and when this data change ends (step 2).
2), from the communication means 12 of the burner controller 10a,
The upper limit value and the lower limit value data are transmitted to the communication means 21 of the remote controller 20 (step 23), and the data are received by the communication means 21 of the remote controller 20 (step 24).

Then, the data received by the communication means 21 is stored in the ROM 22 of the remote controller 20,
The upper and lower limit data are rewritten (step 2
5).

In this way, the burner controller 10
When a cannot supply hot water at the hot water set temperature set by the remote controller 20 due to the performance of the water heater main body 10 and the usage environment, the upper limit value and the lower limit value that can be set from the remote controller 20 are changed. Therefore, it becomes possible to perform remote control according to reality.

Although the above-described embodiments of the present invention are configured to be capable of performing the various operations described above, they are not necessarily configured to be capable of performing all of these operations. It is not necessary, and it is possible to configure so that only a part of the operation can be performed.
