I'm about to install a ceiling fan, and I will tap into the circuit that feeds the wall outlets. OK so far? If I install a wall switch rather than just rely on the pull chain, I will pick a fan switch with a speed controller. Some fan controllers say they are for "2 wire installation" and some say "3 wire installation"? I guess it means that a 3-wire installation has black and white coming from the breaker box to the switch, with black, white, and red between the switch and the fan. Right? Why are there two kinds?
