Abstract: An object is to enable the dealer or user of an air conditioning apparatus to recognize that the heat dissipation amount of a heat exchange device is less than the heat dissipation amount expected of the air conditioning apparatus. A control device detects a hot water outflow temperature being a temperature of a fluid heated by a heat pump device, and a return temperature being a temperature of the fluid before being heated by the heat pump device, and checks whether or not a temperature difference between the detected hot water outflow temperature and the detected return temperature is smaller than a predetermined first value. If the control device judges that the temperature difference is smaller than the first value, it displays insufficiency of the heat dissipation amount of a heat exchange device, on a display of a remote controller.
