BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be shown and the features thereof will be described in more detail.

FIG. 1 is a diagram showing a configuration of a hot water supply apparatus according to one embodiment of the present invention. As shown in FIG. 1, the water heater includes a water heater main body 10 and a remote controller 20 for remotely controlling the water heater main body 10. The water heater main body 10 includes a burner controller 10a for controlling the burner, together with a burner for burning fuel, a heat exchanger (not shown) for exchanging heat between combustion gas and water, and the like.

The burner controller 10a includes a hot water temperature detecting means 11 for monitoring hot water temperature, a communication means 12 for communicating with a remote controller 20, an upper limit of a hot water temperature range which can be set from the remote controller 20, and A temperature range changing means 13 for changing the lower limit value and a control means 14 for controlling these means are provided.

The remote controller 20 communicates with the communication unit 12 of the burner controller 10a, and the upper limit transmitted by the communication unit 12 is changed by the temperature range changing unit 13 of the burner controller 10a. Storage means (ROM) 22 for storing value and lower limit data, operation means 23 for inputting setting conditions, etc., display means 24 for displaying hot water supply set temperature, switch sounds and alarms when conditions are changed or in an emergency Sound output means 25 for outputting sound, and control means 25 for controlling each of these means
It is comprised including.

In the above hot water supply apparatus, a setting condition change mode in which the hot water temperature range settable from the remote controller 20 can be changed can be selected from the remote controller 20 side. And the remote controller 20
To enter the setting condition change mode so that the remote controller 20 can arbitrarily change the hot water supply temperature range.

Next, a description will be given of the operation of the hot water supply apparatus configured as described above in the case where the hot water temperature range that can be set by the remote controller 20 is changed.

[Operation Mode 1] As shown in the flowchart of FIG. 2, first, the remote controller 20 is operated to enter a setting condition change mode (for example, a maintenance mode) in which the hot water supply temperature range can be changed (step 1). .

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

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

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

[Operation Mode 2] As shown in the flowchart of FIG. 3, the temperature range changing means 13 for changing the upper limit value and the lower limit value 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).
Thereafter, data change is determined (step 12).

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

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

Thus, the burner controller 10
Since the hot water temperature range can be changed from the remote controller 20 on condition that the temperature range changing means 13a is operated, the hot water temperature can be easily changed from the remote controller 20 without impairing safety. The range can be changed.

Here, the burner controller 10
The case where the upper limit value and the lower limit value of the hot water supply temperature range are changed by operating the temperature range changing means 13 of a and transferred to the remote controller has been described.
By transferring data set in advance to the burner controller 10a of the water heater main body 10 to the remote controller 20 as the hot water supply temperature range that can be changed by the remote controller 20, 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 is also possible to configure so that it can be changed.

[Operation Mode 3] This operation mode is used when the 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 use environment (for example, the remote controller 20). (For example, when hot water supply at the settable lower limit is impossible).

As shown in the flowchart of FIG. 4, when the burner controller 10a determines that it is impossible to supply hot water at the hot water supply set temperature set by the remote controller 20, the voice output means (warning means) 25 issues an alarm. While generating a sound, 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 is completed (step 2).
2) From the communication means 12 of the burner controller 10a,
The data of the upper limit value and the lower limit value are transmitted to the communication means 21 of the remote controller 20 (Step 23), and 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 limit and lower limit data are rewritten (step 2
5).

Thus, the burner controller 10
If a cannot be supplied at the hot water supply set temperature set by the remote controller 20 due to reasons such as the performance of the water heater main body 10 and the use environment, the upper limit value and the lower limit value that can be set from the remote controller 20 are changed. As a result, it is possible to perform remote control according to reality.

In the embodiment of the present invention, various operations as described above can be performed. However, it is not always necessary that all of these operations can be performed. It is not necessary, and it may be configured such that only a part of the operation can be performed.

The present invention is not limited to the above embodiment in other respects. Specific values of the hot water supply temperature range that can be set by the remote controller, and the remote controller is operated to enter the setting condition change mode. Specific operation procedure at the time of entering, a specific method of transferring the data of the upper limit value and the lower limit value of the hot water temperature range from the water heater main body to the remote controller through communication, a display means for displaying the hot water set temperature, a condition, Various applications and modifications can be made within the scope of the gist of the invention regarding the configuration of the sound output means for outputting a switch sound or an alarm sound at the time of change or emergency.
