Fans with an integral timer need a 3 core and earth supply to allow the unit to run on after a light is switched off. It must also be possible to isolate the fan by means of a pull switch inside the bathroom, or a fan isolation (3 pole) switch outside of the bathroom.
Before attempting fan or any other electrical connection ensure all circuits are off.
Isolation switch must be on a pull cord inside a bathroom or as above a switch on the outside.
