Wiring the fan to a variable speed control switch lets you make fine adjustments to the fan s speed.
Ceiling fan speed controller circuit.
There are several ways to control ceiling fans and light kits.
A ceiling fan s wiring is integral when it comes to controlling its speed.
This wiring diagram illustrates the connections for a ceiling fan and light with two switches a speed controller for the fan and a dimmer for the lights.
Ceiling fan with light kit wiring diagram.
In order to control the fan s speed the fan needs its own system of wires separate from that of the lighting element.
The source is at the switches and the input of each is spliced to the black source wire with a wire nut.
Variable speed controls must be specially designed for use with ceiling fans.
The slow speed is obtained by using the 4 3uf capacitor purple p the medium speed is obtained by using the 2 1uf capacitor red r and the high speed is.
Ceiling fan and light kit control options.
If you install a ceiling fan without wiring it properly it may prove impossible to operate the fan without the light on and vice versa.
