PROBLEM TO BE SOLVED: To actually feed an electrical charge or the amount of power consumption and to enable a user to easily achieve an energy-saving target by providing an automatic operation stop mode for stopping operation automatically when either the electrical charge or the amount of power consumption being set in advance is reached when home air-conditioning equipment is operated. SOLUTION: When an automatic operation stop mode is selected, an operation/stop button 3 of a remote controller 1 is pressed. Then, when an indoor machine 5 receives an operation signal with an automatic operation stop signal, it starts operating air-conditioning equipment. The calculation of an electric charge is initialized simultaneously with the operation start, an electric energy is integrated by a consumption current value and is converted to the electric charge by a preset power charge. In this case, most of it is the electric energy of an outdoor machine 6 and represents the total electric energy of the air- conditioning equipment, but the electric energy of the indoor machine 5 also needs to be added for improved accuracy. An operation continues as far as the converted electric charge does not exceed the preset electric charge. However, when the set electric charge is exceeded, the operation of the air- conditioning equipment is automatically stopped. |
