Radio Frequency means the remote has a long range and does not have to be pointed towards the fan to operate. It has multi-channel capability to allow for other remote controlled ceiling fans to be used in the house without interfering with each other
A remote control can make installation easier by avoiding having to run wires to a wall control.
Note that one remote per fan is required as the receiver part of the remote has limited capacity. This applies to all remotes.
This model does not have a light dimming function.
