Abstract

PURPOSE:To remotely control the ventilating fan operation mode by simplified circuitry by switching the ventilating fan operation mode in response to a signal from a remote controller which sends out multiple signals and comprises switches that respectively allow the transmission of the plus side signals only, minus side signals only and both from an AC signal source. CONSTITUTION:A remote controller 2 has a switch 2-1 which allows the transmission of the minus side only of AC current, a switch 2-2 which allows the transmission of the plus side only of AC current and a switch 2-3 which allows the transmission of both the plus and minus sides of AC current. By switching the remote controller 2, the wave shape of AC power source can be switched to four different kinds of signal. A pulse converter circuit 3-1 converts the four kinds of signal to corresponding pulse signals which are supplied to a determining circuit 3-2. This determining circuit 3-2 identifies the signal which has been converted by the pulse converter circuit 3-1 and switches the relay contact point of a connection switching circuit 3-3 to regulate the speed of a ventilating fan. As the four different kinds of signal corresponding to high, intermediate, low and stop can be transmitted to perform the three-staged speed regulation with two lead wires, a complicated wiring can be prevented.
