In step S20, the controller 40 determines whether the first temperature sensor 31 is in a normal state by using the diagnosis result in step S18. If the first temperature sensor 31 is in an abnormal state, And controls the driving of the combustion unit 20 so as to supply the heating water by fixing the first heating temperature to the set first heating temperature (S22).

If the sensed outdoor temperature exceeds the fourth temperature in step S44, the control unit 40 controls the driving of the combustion unit 20 so as to supply the heating water by fixing the direct water set temperature to the second direct water temperature set in advance (S46).

If it is determined in step S44 that the sensed outdoor temperature is lower than the fourth temperature, the controller 40 determines whether the outdoor temperature sensed by the second temperature sensor 32 is lower than a preset fifth temperature (S48) .

If the sensed outdoor temperature exceeds the fifth temperature in step S48, the control unit 40 controls the driving of the combustion unit 20 so as to supply the heating water by fixing the direct water set temperature to the third direct water temperature set in advance (S50).

If it is determined in step S48 that the sensed outdoor temperature is lower than the sixth temperature, the controller 40 determines whether the outdoor temperature sensed by the second temperature sensor 32 is lower than a preset sixth temperature (S52) .

If the sensed outdoor temperature exceeds the sixth temperature, the control unit 40 controls the driving of the combustion unit 20 so as to supply the heating water by fixing the direct water set temperature to the fourth direct water temperature set in advance (S54).

On the other hand, if the sensed outdoor temperature is lower than the sixth temperature in step S52, the controller 40 controls the operation of the combustion unit 20 to supply the heating water by fixing the fifth direct water temperature (S56).

Here, the fourth temperature to the sixth temperature are set to distinguish the summer season, the spring season, the autumn season, and the winter season, and they may be set at about 20 ° C, 10 ° C, and 5 ° C, respectively, in this embodiment.

And the first to fifth direct water temperatures are temperatures set for performing heating in emergency operation in summer, spring, autumn, and winter, respectively.

In step S60, the control unit 40 checks whether the counted emergency operation time has elapsed by using the timer 42, and controls the steps S18 to S60 to be repeated until the emergency operation time elapses.

If the emergency operation time elapses as a result of the inspection in step S60, the control unit 40 stops driving each device provided in the main body 11 and ends the process.
