    Hi all,

    Ive purchased the Blauberg Calm Design 4" fan - model 100 ST, it has a timer and integrated pull cord.

    My last fan was timer only and was set-up to activate when the bathroom light was turned on.
    I wanted to ask if anyone knows if the same set-up is possible with this particular model?

    Its a pain turning on the bathroom light and then having to pull the cord on the fan also - i just want to turn it on and off using the bathroom light switch.

    If its possible - how can i do it?

    Post photos of:
    1) the existing wiring
    1a) is there a fan isolator switch?
    2) the connection instructions for the new fan
    3) the connections in the new fan

    If that is the only thing you have to worry about in this world you are extremely blessed.

    Note: the green/yellow wire is not an Earth wire, that was the only coloured sleeve we had as the wire was bare.

    Fig 15, fan 100ST

    We have no isolator switch

    Why not short out the ill switch on the new fan and create a direct feed and dispense with the pull cord

    Also the wiring in the fan you have has no permanent supply for a run on timer so I think this model will accept liking the live switch wire to the terminal for permanent supply and just use as a simple on/off fan with your light switch at present if you want a run then you need a permanent supply via some wiring changes

    What! So you are using the bare CPC of a twin and earth as a line conductor and to cap it off sleeving it green and yellow. Hope you have good life insurance, though doing something so idiotic would probably invalidate it. Red or brown sleeving is very cheap.

    Seriously you need a spark to do this properly and safely.

    To put it tactfully, you are a dangerous fool.

    It baffles me the amount of posts where this sort of thing happens...:eek:

    Someone testing the cable at the fan with a multi meter may well be fooled into thinking there is reversed polarity live and neutral, rather than a live on the earth conductor :rolleyes:

    This is wrong on so many levels.

    This wiring is how it was originally set up, all i did was put a sleeve on the bare wire.

    I asked for advice, not to be insulted

    No, it is not possible without rewiring.

    Nobody is intentionally trying to insult you. It is dangerous what you have done though, I appreciate that is how it was wired before and you just straight swapped it. However like we've said its very dangerous having the cpc there. I would normally say well done for sleeving the bare conductor. Apologies if you felt insulted i'm sure it wasnt peoples intentions!

    It may already be there, but it’s the responsibility of the last person to make sure that any problems are realised and rectified. That’s where experience comes in.

    The bed advice is it’s dangerous and you don’t know what to do to make it safe and you need it to be safe, so you need to get an electrician to tidy it up for you, if being told that is insulting, then so be it.
