The operation of the heat source device (10) is controlled on the basis of the hot water temperature during the set temperature operation set in step 2, and the operation start time and stop time set in the time setting circuit (2). The first mode operation in which the normal operation and the stop of the normal operation as shown in (3) are repeated is performed.

Further, for example, when the second mode is set by the mode selector switch (7) because the temperature does not change much throughout the day, the set temperature set by the temperature setting circuit (1) and the set temperature change The operation of the heat source device (10) is controlled based on the hot water temperature during operation and the setting switching time set by the time setting circuit (2), and normal operation and set temperature changing operation as shown in FIG. 4 are performed. The operation in the second mode in which and are repeated is performed.

According to the above operation control device, the mode changeover switch (7)
When the 3rd mode is selected by, the set temperature change operation with the set temperature changed to a low value is performed between the normal operation time of the heat source device (10) at night and in the morning. It is possible to shift from the operation to the set temperature changing operation, reduce the operating time of the heat source device (10), and reduce the operating cost of the heating device. Also, when waking up in the morning, the set temperature changing operation is automatically switched to the normal operation, the heating capacity is increased, and the comfort when waking up can be improved. Further, the heat source device (10) can be automatically stopped at, for example, about 10:00 when the ambient temperature gradually rises, and the operating cost of the heat source device (10) can be further reduced.

Further, it is possible to automatically start the operation of the heating device, switch from the normal operation to the set temperature changing operation, switch from the set temperature changing operation to the normal operation, and stop the operation at all set times, It is possible to eliminate the troublesome operation of the user for changing the set temperature and the operation of starting and stopping the operation, and to greatly simplify the operation of the heating device by the user.

Further, the operation control device has a first mode, a second mode,
And the mode changeover switch (7) for changing over the third mode, the mode can be arbitrarily changed according to the life pattern of the user or the other climate in which the heating device is set. Comfortable and economical heating suitable for the climate can be provided.
