First on the WC-212,it is a 2 wire but only on specific fans that came with it in the box with the fan, it is not designed for your fan since the fan did not come with one.
It can only replace existing WC-212 units or used in conjunction with an RC-212.
The original wall control that came with the fan:
Connect the power to the black/white wire on the control, then connect the wire going to the fan on the black wire on the control.
Cap the blue wire off on the wall control, it is unused since you do not have enough wires to operate the light.
At the fan ceiling box, the fan white connects to the ceiling white.
The fan black connects to the wire that goes to the switch in the previous switch wiring
The blue is not used on the fan.
I was unsure of the exact wiring on your posting, so wanted to post this to insure the original was wired properly.
