Based on your comments, the old switch was probably a fan speed control with a wire for the light kit. The black wire was the hot coming from the panel, the red wire was for the fan motor and the yellow wire was for the light kit. This control enabled you to control the speed of the fan motor, but it only allowed the light kit to be turned on or off, no dimming.
The new control you purchased is just a fan speed control only, with nothing for the light kit. The black wire is the hot coming from the panel, the red wire is for the fan motor and the green wire is the ground wire. I would recommend that he disconnect the green wire from the yellow wire and connect the green wire to a ground somewhere and cap off the yellow wire in the wall.
If you want to control the light kit, like before, I would recommend that you purchase a Lutron SFSQ-LF or SFS-5E fan speed control. These controls would wire just like the control that you replaced.
Hope this helps. Any questions, please call.
