−１１７１０１会報で知られている。Originally, in upper O class water heaters, the hot water temperature adjustment knob was set to the high temperature side and the tta power was adjusted from "weak" to "strong" to reduce the amount of excess water.
If you switch to water temperature, boiling will occur in the water exchanger, so in order to prevent this, a stopper piece that is linked to the capacity switching device is used to adjust the operation of the water temperature control knob to the lowest level adapted to the capacity ``strong''. The one that made it possible to freely control the amount of water in percentage terms was written by Jikoaki If.
It is known for its -117101 newsletter.

摘みＫよる湯温調節の目安をつけに（い不都合を伴う。However, in this case, if the hot water temperature adjustment knobs are in the same operation position, the amount of excess water will remain constant regardless of the capacity, so by switching the capacity, the hot water temperature will be greatly carbonized, and the hot water temperature adjustment knobs will be in the same position. To get a rough idea of how to adjust the hot water temperature according to K (with some inconvenience).

m own 1! In a device that is equipped with an O capacity switching device and an island flow rate control device that adjusts the amount of excess water flowing into the water bath in conjunction with the hot water temperature adjustment knob, the trial amount control device has a water temperature adjustment knob that controls each operation. A flow rate switching means that can freely switch and adjust the amount of water flowing through the water in at least two stages, large and small, is built in, and the flow rate switching means is switched in conjunction with the switching operation of the capacity switching device. do.

小中ＫＭ、制される。In the original model, the hot water temperature adjustment knob is in the same operating position.
When switching the t capacity, the hot water supply state shifts from the O point on the a line, for example, to the OB' point on the bII line, where the water flow rate is the same as the taper, and the hot water temperature changes greatly, but according to Motoya, the hot water temperature adjustment Even in No. 11 with the picked trout at the same operating position, the excess water amount is switched between large and small as described above in conjunction with the capacity switching operation, and thus the hot water exiting state moves from the widening point to point B, and the tap water temperature can be changed. Target small and medium KM is controlled.
