[Product Information]

IT IS ONLY A TRANSMITTER. This package does not include a receiver. 9V battery is not included.
Green button working with the light to control the brightness of the light.
Make sure your original remote the same as the picture shows. It has 3-speed(Low/Medium/High) to control fan.
This is the remote control for the ceiling fan. They should match the switches on the transmitter inside the ceiling fan. As long as the fan has the receiver in it this remote will work with your harbor breeze ceiling fans. Just remember to set the 4 dip switches inside the battery compartment(they are kinda hidden behind the slot for the battery itself).
Look inside the old remote with the battery cover off. There is a series of "DIP" switches(4) with a pen, slide the switches in the new remote to match the same pattern as the old remote. Replace the battery in the new remote and things should work.
