Hampton Bay ceiling fan doesn't work properly with wall dimmer switch?
If you want to use a wall fan control, you'll likely have to remove the remote fan control receiver from the unit.  The remote receiver in the fan housing controls the fan speed, and will not allow the wall control to override it.  

In the most basic case, the remote receiver will have "input" wires connected to the standard household wiring (ungrounded, grounded, grounding).  The unit will then have "output" wires that connect to the fan, and/or light kit. Because of this, controlling the "input"  of the remote receiver will have no effect on the "output". 

The procedure for removing the remote receiver will completely depend on the unit.
