Minka-Aire WC106-WH is a dual-slide ceiling fan/light control that allows you to conveniently adjust the speed of your fan and turn the light on/off from the wall. It is designed for use with capacitor speed-controlled ceiling fans only. The control features a safety mechanism that prevents erratic speeds and possible damage to your ceiling fan. Installation requires a three-conductor cable with a ground wire between the control wall box and the ceiling fan outlet. Refer to the included schematic for proper wiring.
