Ok, thanks.I may be misunderstanding what you posted.The fan originally came with a 3 wire wall control. Which the black/white connected to power and then black to the fan, the blue to the light off the wall control.The WC-212 is supposed to be used only on fans that originally came with one and is not designed as a stand alone add on for fans.It is a 2 wire control as opposed to the original 3 wire wall control.Not sure how the original wall control was wired, but should work if you have 3 wires for the connections.You also mentioned "fans" in the last post? Not sure why the plural?
Manufacturers like to make it difficult on so many of these fans, limiting which wall controls work with the different fans and not universal.
I purchased and installed the F510-ORB Minka Aire Space Saver. It came as a 3 wire (Blue/Black/White) and I currently only have 2 wires. I connected the Black (to AC) /White (to Neutral) wires at the Fan and the Black (to Fan) and Black/White (to AC) wires at the switch knowing I would not be able to use the light. The switch has four speeds but only high will turn on.
The Minka site offered the WC212 switch as an alternative the two wire limitation. I combined the blue and black wire to the AC wire at the fan and and the Black (to Fan) and Black/White (to AC) wires at the switch That also uses the high speed and cannot be controlled other than on and off.
Thanks for the help.
