Abstract

PURPOSE:To enable an operating condition of a ventilation fan to be displayed in an operator's hand switch in a remote selector by a method wherein a plurality of a semi-wave phase control signal having different phase control angles can be transmitted or received as an operation selector signal and a state signal between the operator's hand switch and a ventilation fan. CONSTITUTION:A phase control angle of a semi-wave phase control circuit 2-1 is changed over by changing over a selector switch 2-2. It is transmitted to a control circuit 3 for a ventilation fan and then operation of the ventilation fan is changed over. A discrimination circuit 3-3 for the control circuit 3 may transmit a pulse signal corresponding to a semi-wave phase control signal sent from an operator's hand switch 2 to an oscillation circuit 3-2a, control a semi- wave phase of a phase control angle as desired and then transmit it to a voltage sensing circuit 2-3 of the operator's hand switch 2. The voltage sensing circuit 2-3 may detect a semi-wave phase controlled signal and display the operating condition. With this arrangement, it is possible to display the operation condition of the ventilation fan to the operator's hand switch.
