I am a complete amateur when it comes to wiring, but am trying to learn to try to do things myself to avoid having to hire an electrician.

I bought an updated ceiling fan to replace the ceiling fan that was installed by the builders 10 years ago. The old fan was controlled by a 3-button wall switch with these buttons: Fan, For/Rev, and Light (and On/Off that controlled everything).

I removed the old fan and saw that there were 4 wires on the fan: black, white, blue, and green. In the ceiling there were 4 wires too: black, white, brown, and copper. They were attached as follows: black-black, white-white, brown-blue, copper-green.

When I put the new fan up, the instructions said that I should connect black-black+blue (black was fan hot, blue was light hot). At first I tried black-black and brown-blue like it was before, but only the fan would turn on, not the light. So I switched it to how the manual said, and both fan and lights work.

However, the whole unit (fan and lights) turn on when I hit the on/off switch on the wall, and the 3 buttons do nothing. I hear a slight "whir" in the fan when I do press the buttons, but nothing else happens. The pull strings work for on/off, but as it is on a vaulted ceiling, that really isn't an option for normal use in case we just want the lights or just want the fan on.

Did I buy the wrong type of ceiling fan that isn't compatible with the wall switch? Is there a different type of switch I can install in the wall to control the fan/light separately? If not, is there anything I can do to modify the fan so that it works with the switch?

Thanks for the help in advance!
