I have two hampton bay ceiling fans, either remote I use turns the other one on. Do you know how to solve this problem. I tried everything, it's very anoying. Is there a way to change the frecuency on the remotes or something..

Yes, on the remote, where you put the battery in, there are jumpers with numbers. They are also on the transmitter. Just change them to match each other. That way both your units won't have the same frequency.
