In this case, the controller 140 may receive a desired temperature reset input from the user after the indoor temperature reaches the desired temperature. That is, upon receiving the desired temperature reset input from the user, the controller 140 must adjust the operation of the outdoor unit 110 , the indoor unit 120 , and the circulation device 130 so that the indoor temperature changes according to the desired temperature change.

After receiving the desired temperature reset input, the controller 140 may adjust the operation of the outdoor unit 110 and the indoor unit 120 in consideration of the state of the indoor space in which the heating device 100 is installed.

In an embodiment of the present invention, the controller 140 may stop supplying heat by stopping the operation of the compressor 111 when the door state is closed when the desired temperature reset input is received. In other words, if the state of the door is closed, the controller 140 stops the operation of the compressor 111 to prevent the high-temperature refrigerant from being transferred to the water-refrigerant heat exchanger 121 , and through this, to the circulation device 130 . Hot water can stop being delivered.

If the indoor temperature has not reached the desired temperature, the controller 140 controls the outdoor unit 110 , the indoor unit 120 , and the circulation device 130 in the conventional manner, and then determines whether the indoor temperature has reached the desired temperature again. do.

If the indoor temperature has reached the desired temperature, the controller 140 receives a desired temperature reset input from the user (S320).

After receiving the desired temperature reset input, the controller 140 receives inquiry state information from the detection sensor 150 ( S330 ).

Then, the controller 140 controls the operation of the outdoor unit 110 and the indoor unit 120 based on the inquiry state information (S340).

In more detail, in an embodiment of the present invention, when the controller 140 receives the desired temperature reset input and the door is closed, the controller 140 may stop the operation of the compressor 111 to stop the heat supply. In addition, in another embodiment of the present invention, the controller 140 may reduce the speed at which the pump 123 pumps water if the door is closed when the desired temperature reset input is received.

In addition, in an embodiment of the present invention, the controller 140 may maintain the operation of the outdoor unit 110 and the indoor unit 120 if the door state is an open state when the desired temperature reset input is received.

As described above, in the method of controlling the heating apparatus 100 according to an embodiment of the present invention, the operation of the outdoor unit 110 and the indoor unit 120 is controlled using the inquiry state information, so that the user can ensure that the indoor temperature is the same as the desired temperature. You will feel that you are in control. In addition, by operating differently depending on the state of the door connected to the indoor space, the heating device can operate more efficiently.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made. In addition, although the effects according to the configuration of the present invention are not explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the configuration should also be recognized.
