Yes another extractor fan thread, but I have checked all previous posts and none seem to match my circumstances...
I'm in the process of replacing a timed extractor fan in my bathroom with a newer model.
The bathroom has a swtiched fuse outside above the door, a pull cord switch inside, a light, and the fan.
Upon removing the old timed fan I was suprised to see so many wires. There are two cables running to the fan, and each cable is 3-core (blue,yellow,red) and bare earth. So eight wire all together. These were wired into a choccy block on the old fan but there wasn't much in the way of a wiring diagram on the old fan to say what was what. I wrote this info down as best I could and then promptly lost the note. oops
After I removed the fan I insulated the end of both of the cables that ran to the fan. I found that the light could still be operated via both the pull cord and the outside fused switch.
I'm now trying to fit a new timed fan. Unfortunately I don't have the instructions (yet... they were missing from the box but I have requested replacement) - but I can tell you that there are only three connections - L, N and T - I assume L and N is live and neutral and T is the switched live?
Anyway, even when I get hold of instructions I'm not sure they will help as I don't think they will explain why I have two sets of 3 core cable.
Can anyone advise how I should wire up the fan?
