Abstract

PURPOSE:To perform a remote operation of a plurality of ventilation fans with one operator's hand switch by a method wherein a control circuit for receiving a phase control angle signal from the operator's hand switch in a remote selector and transmitting the signal to each of the ventilation fans is arranged at the ventilation fan. CONSTITUTION:A switch 2-2 of an operator's hand switch 2 is changed over to vary a phase control angle of a phase control circuit 2-1 and then outputs it to a control circuit 3 for a ventilation fan 1. The control circuit 3 may adjust the speed of the ventilation fan 1 in reference to a phase control angle signal to be inputted. At the same time, the control circuit 3 may transmit the same signal as that sent from the operator's hand switch 2 to another ventilation fan 1' so as to perform an adjustment of speed in the same manner as before. With this arrangement, it is possible to perform a remote control of a plurality of ventilation fans with one set of operator's hand switch.
