御する。When a test operation is performed with the water heater 1 and terminals such as the washing machine 8 and the dishwasher 9 installed, the respective devices are operated, and the usage amount (hot water supply amount) p peculiar to the respective devices is calculated. The hot water supply pressure q is measured by the hot water supply amount detection sensor 12 and the hot water supply pressure detection sensor 13, and this is input to the control circuit 14 as terminal information. When the use of the terminal is started and the hot water supply amount p ′ and the pressure value q ′ are input from the hot water supply amount detection sensor 12 and the hot water supply pressure detection sensor 13 to the control circuit, the control circuit 14 compares with the terminal information that has been input in advance. And p = p ',
When there is a terminal of q = q ′, the water heater 1 is controlled so that the temperature of the specified terminal becomes a predetermined temperature.

It is a -q characteristic and does not include piping or the like. Therefore, it is necessary to rewrite it into the pq characteristic of the system. Therefore, during the test operation, the pq characteristics are rewritten based on the following concept.
【００１１】機器単体のｐ−ｑ特性を、ｐ＝ｆ（ｑ）と
すると、その他配管等を含めた圧力損失は ｐ＝ｆ（ｑ）＋ｋｌ＊ｑ＾２で表せられる。Assuming that the pq characteristic of the device alone is p = f (q), the pressure loss including other piping and the like can be expressed by p = f (q) + kl * q ＾ 2.
【００１２】試運転時のデータを（ｐｌ、ｑｌ）とする
と、 ｐｌ＝ｆ（ｑｌ）＋ｋｌ＊ｑｌ＾２となり、 ｋｌ＝（ｐｌ−ｆ（ｑｌ））／ｑｌ＾２となり、ｋｌが
決定される。Assuming that the data at the time of the test operation is (pl, ql), pl = f (ql) + kl * ql ＾ 2, kl = (pl-f (ql)) / ql ＾ 2, and kl is determined. .

所で同時使用した場合も考察する必要がある。Therefore, if the data of p and q are obtained irrespective of other systems such as piping, the use state of the dishwasher and the washing machine can be determined based on the data. (Besides, by measuring the integrated flow rate and the hot water supply time, it is possible to specify the temperature more reliably.) In the concept of this control, the pq characteristics are accidentally the same at other places of use. It is also necessary to consider the case where pq data becomes the same in other places or the case where the same pq data is used in another place while being used in a dishwasher or the like.

高温で出湯する。In such a case, the base temperature is set to the remote control set temperature for temperature control, and in the first pre-washing step of the dishwasher, hot water is supplied at that temperature, and a wait until the assumed second hot water supply is performed. If hot water is supplied within the time range, it is determined that the dishwasher is being used, and hot water is supplied to the dishwasher at a high temperature.

Since a change occurs in the pq data, the set temperature of the temperature control remote control is given priority at the same time. When the pq data returns, the mode returns to the dishwasher / washing machine mode. FIG. 2 is a flow chart showing the above concept.

In this case, the flow rate control valve 16 is attached to the hot water supply line 3b side where the pressure is low with respect to the hot water supply line 3c branched by the header 3a, and if p '= large and q' = small, the data If there is a change, the flow control valve 16 is throttled. Looking at the data of p'.q ', the flow control valve 16 is throttled when p' = small and q 'is large and when q' fluctuates further.
