I decided to fit a new bathroom extractor fan with a timer, but not entirely of the complete wiring system. The fan fitted before had a timer too.
As far as I’m aware, the coloured wires (see photo attached) are as follows; - Red single = permanent live - Red and yellow = switch live - Black = Neutral. - Blue = also Neutral.
I’m pretty sure, but I believe the wires go into the following sections in the photo provided: Red alone goes into L, red and yellow wrapped around each other go into Ls and Black and Blue both go into N?
