This would have been much more difficult without reviewer Elizabeth B. She explained everything as clearly as the manufacturer should, so I recommend you to refer to her review. As other reviewers have noted, it's not universal, but designed for use with newer fans with a specific receiver type. If you have an exhaust chain fan, you will need to install a receiver, sold separately. The wall controller that came with our fan sucks. The light is hidden in the middle and most little fingers still turn on the fan. Stupid. I wish I could have just a light switch but it was a cheaper alternative and at least better than what we have now. We chose not to plug it in at all and use it as a wall controller. I like that these are AAA batteries and not the obscure silver button cells, but I don't like that I have to unscrew them to get to them. For pairing instructions read Elizabeth B's review. Casablanca answers all questions on her website and encourages you to call or email her, which is stupid and cheaper here than on her website.
