PROBLEM TO BE SOLVED: To remove switches from the main body of an indoor machine by a method wherein a pulse signal outputted from a Hall element by rotating manually an indoor fan provided in the main body of the indoor machine is used as an operation signal for an emergency operation switch, a trial operation switch, a time reduction switch, etc. SOLUTION: A manual rotation means 1 for rotating an indoor fan 2 manually is provided for the main body of an indoor machine, while a storage part 6 which stores, as a reference waveform pattern, a waveform pattern of a pulse signal outputted from a Hall element 4 when the indoor fan 2 is rotated by the manual rotation means 1 and a pattern comparing part 5 which compares the waveform pattern of the pulse signal outputted from the Hall element 4 with the reference waveform pattern, judges an input of an operation signal to be present when the two patterns coincide with each other and outputs the operation signal to a control circuit 7 are provided, and the control circuit 7 executes a corresponding operation mode in accordance with the operation signal inputted. |
