Extractor fan with timer on twin and earth?

[Chadmanfoo]

I had an electrician in recently to install some bathroom lights and run a cable for an extratctor fan. I just got around to installing the fan and realised he used a twin and earth. This is great but means i can't install a fan with timer.

Is there any way i can use what is have to run a timer? The cable has been plastered in now so i don't think replacing it would be possible at this stage.

I installed fans with run on and they annoyed me so much by taking the heat out of the bathroom whilst I was in the shower that I disconnected the timer function and just rewired them though a normal switch so I switch them on after I get dried and simply switch them off later.

Thanks for the link. I should mention i've already installed an Airflow Icon. Don't much fancy replacing it. It's looking like i would need to find a permanent live from somewhere else or live with it turning on and off with the light.

OK, nice fan. You will already have a timer module installed in the fan then?
If so, you have four choices
1. Ditch the timer module and fit an ICON PIR module (return the timer module to supplier, or sell it on FleaBay)
You'll need to provide a permanent live for the PIR, this can probably be done at the light switch, or the light itself, depending on where the 2C&E is connected.
2. Find a permanent live FROM THE SAME LIGHTING CIRCUIT,and connect this to the fan.
3. Rip out the 2C&E cable and install 3C&E. But you'll still need to find a permamnt feed, so thats probably the same as 2 above
4. Remove the timer module and connect the 2C&E and run the fan without a timer and put up with a steamy mouldy bathroom.

PS Didn't you tell the electrician that you wanted a timer fan? If so, get him/her back to sort it.

Thanks Taylor. It sound like anything except option 4 would need a permanent live.

I just told the electrician that I planned to install an extractor. I guess I should have been more specific but hindsight is 20/20. The ceiling and walls have been skimmed and I have insulated the wall where the isolator switch is so replacing the cable will be more trouble that it's worth at this point, as would trying to run a permanent live from another source.

Frustrating but certainly not the end of the world. We will just have to leave the window open or keep the light on longer after a hot bath.

Thanks to everybody who took the time to reply.

Maybe you don't need a fan.

Another theoretical option which I don't think has been suggested, albeit maybe not cost-effective, .... if there is access in the vicinity of the light fitting/ceiling rose/whatever (and assuming that's where the feed to the fan comes from), you could theoretically install some sort of run-on timer module close to the light/whatever, so the 2-core feed to the fan would then have a timed run-on.

I haven't looked, but I presume that such modules/timers are available.

Kind Regards, John

Correct

Correct

Thanks for confirming. How much?

Thanks. That's clever. Did you have to 'do something' to make the image behave as a hyperlink?

Thanks. As with so many things, very easy when one knows how

The only problem with that system is that, unlike a textual hyperlink (which shows as blue) there is presumably no way that a viewer/reader can know that it is a hyperlink (which is why I didn't realise!).
