[u][b]Problem[/b][/u]
I have a timed fan for the shower. Its only to come on when I pull the ceiling cord, and then stays on for 10 mins after I turn it off again. Its not linked to the lights in any way, -just the way we wanted it (long story!)
The electrician who put it in gave us a switch without any "on/off" indicator/LED.
The ammount of times the damn fan has been running and we couldn't remembered whether it was on or off, or come home to find it still running as we hadn't turned it off etc... started to really get annoying.
[b][u]what Ive done so far[/u][/b]
I bought a switch from B&Q with a light and red/white on-off indicator.

[u]wiring....[/u][/b]
The supply cable is the usual 3 core brown/blue/earth
The fans cable is brown, grey, black and earth.
The 'old' switch has two terminals that were used, 'common L' and 'L1': the joint 'common L' terminal, into which two brown live wires went; the blue(supply) and grey(fan) were joined in a little plastic block. The black (fan) wire had a brown sleve put over it and was put into L1 terminal.
(earths all joined together as usual)
The new switch has a supply and demand Live and a supply and demand neutral.
I wired the two live brown, that had previously been connected, to the supply Live and the black (with brown sleeve) to the demand live.
The blue and grey I wired to the supply and demand neutral respectively.
The switch works fine, but the timer circuit does not. ie: turn on and its on...turn off and its off...no timer run-out.
Presumably I have screwed up with the timer wire which I have put in the wrong place...
Can I ask where should it go?
(and I do know that I'm breaking the law -however the last registered electrician wired up the boiler wrongly -twice, and the last corgi registered plumber plumbed in the boiler back to front, and the lelectrician before that failed to notice the entire house was not earthed!! - I have a lot more faith in your collective wisdom and my common sense than our local tradesmen skill!)[u][b][/b][/u][b][code][/code][/b]
