PROBLEM TO BE SOLVED: To provide a fan furnished with a fan motor and two pieces of signal conductors made of a rotation number change-over control signal conductor and a rotating state output signal conductor and capable of rotating the fan motor by the number of rotation in accordance with a rotation number change-over control signal input through the rotation number change-over control signal conductor and informing a detailed data without increasing the number of the signal conductors concerning the fan to output a rotating state of the fan motor through the rotating speed output signal conductor. SOLUTION: This fan is furnished with a data memory part, memorizes the data in a non-volatile state and outputs the data through the existing rotating state output signal conductor.
