So I removed an old ceiling fan in our spare room and installed a Hunter. The old fan would stay on unless you pulled the chain to turn it off. The light was switched by the wall switch. Now the wall switch turns the light and fan off. How do I get the wall switch to just turn off the light and leave the fan running. I have to be honest I didn't pay attention when unwiring the old. All the other fans in tje house operate the same way as the one I just took down. What am I missing?
