ることにより解決される。 By the way, as mentioned earlier, in this type of hot water supply and heating system, it is necessary to increase the set temperature of the thermo circuit in order to obtain hot water for heating at an appropriate temperature, but if you switch to hot water supply with the set temperature unchanged, you will end up with an unnecessarily high temperature. It will provide hot water. However, according to the present invention, when the heating is stopped, the set temperature variable circuit is activated to automatically lower the set temperature. This will be explained based on FIGS. 2 and 4. When the input voltage of the voltage comparator 18 exceeds the reference voltage, the output voltage becomes low, while the output voltage of the voltage comparator 19 becomes high, causing the transistor 21 to conduct and the relay 20 to operate. Therefore, the set temperature is the temperature at the point where the input voltage crosses the reference voltage as shown in FIG. On the other hand, the input voltage decreases because the resistance value of the detection element 11 decreases as the water temperature increases. If you close the heating switch 23 now, the heating signal is sent to the transistor 31 by the circuit 32, which makes the transistor 31 conductive and lowers the reference voltage.On the other hand, if you open the heating switch 23, the transistor 31
is cut off and the reference voltage increases. Therefore, the temperature during hot water supply is set to t 2 −t 1 lower than that during heating, and unnecessary high-temperature hot water is not supplied during hot water supply. Furthermore, the present invention can also prevent boiling in the heating heat exchanger 4 and premature turning off of the high limit switch 36 due to the stacking phenomenon.
That is, in this type of hot water storage tank type heating device, when a small amount of hot water is supplied intermittently, the burner burns intermittently, and the amount of heat given by the burner combustion becomes excessive compared to the amount of water flowing in, and as a result, the hot water storage tank 3 The temperature of the water inside the heating heat exchanger 4 becomes extremely high, and the inside of the heating heat exchanger 4 boils.
Also, normally a non-automatic return type high limit switch is activated, but this problem can be solved by lowering the set temperature.

る。(Effects of the Invention) As explained above, according to the present invention, the set temperature of the thermocircuit automatically decreases when the heating operation is stopped, so there is no need to change the setting again when supplying hot water after the heating stops. Even if the above-mentioned stacking phenomenon occurs, boiling of the heating heat exchanger 4 and premature turning off of the high limit switch are prevented.
