I recently installed a Hampton Bay Ceiling Fan (Hawkins 44") everything works great except for the wall mounted light switch. The switch turns the lights on & off but does not cont roll the fan? Where did I go wrong? I have 4 wires coming from the ceiling white,black,ground & red. I know white to white,black to black,ground to ground... what do I hook the red one to & is this the answer I am looking for?
