Extractor fan – Is a re-wire change to change timer duration?

[Johnuk]

get back the person who fitted it to correct the prob, as u said u wanted a time fan

This was an installation of a brand new en-suite which included new lights and "Xplelair Inline Extractor Fan with Timer". The functionality we now have is not in line with the quotation. So if the electrician has wired it up in way in which the timer does not work, is this our fault? We don't see why we should pay for this to be rectified. This has only come to light as immediately after fitting we asked for timer to be adjusted.

all bolis down to what was quoted for by the spark. if he had quoted to fit a timer overrun fan, then it's his problem if he's not wired it correctly. if he quoted just to fit the fan to run with the light, then it's your responsibility to pay for the extra wiring involved.

Oh oh oh. Sorry I didn't realise he had done all the wiring. If he's wired all the lights and a new feed to a fan then he is totally in the wrong.

Get him back. If he doesn't come back, complain to his registration body and they will make him.

Apologies for my assumptions.

You have now give more info and your op now makes sense. It seems that the spark has not wired it for a timer fan. IMHO it's his problem

Sounds like hes lashed in a twin, and ran away.

Few other things to ponder,,

Fan isolation switch,is the fan protected by a fuse or does it have thermal cutout on it, where you issued a certificate for your electrical work done lights and fan, are your lights compliant to the bathroom zones.

Not trying to make a mountain out of it, but these things need to to be looked into, by any electrician worth his salt.

Not wanting to be funny but why would you specify the ventilation - are you a ventilation expert - only jesting ...... it seems easy until you know the truth !

The link is to an Axial fan - i hope there isn't too much ducting as it may not perform if too much.

There are a lot of different things to take into account in selecting the best ventilation solution, you could see Energy Savings trust web site, or study the downloadable Domestic Ventilation Compliance Guide along with Part F of the Building Regulations.

It sounds like you've got a system 1 type installation, For these systems " when installing a fan within a bathroom or wc with no openable window the fan should have a 15 minute over run " and " in rooms with no natural light, the fan should be controlled by the operation of the main light switch within the room."

Is your bathroom door undercut by 10mm above carpet or other finish ?

Has the room got a window ?

Flexi duct used or rigid ?

Generally point of extract should be as far from the internal door as possible to achieve best ventilation, however that may mean you get a short circuit to a window background ventilator (if fitted) or you may just go for above the shower ?

All that said i am teasing a bit - ventilation on new build is now a controlled service and when you see how many installations are actually poorly installed you can see why. How many electricians have an air flow meter to ensure the fan performs ?

PM me with as much detail about job inc sketch of room layout etc and i can provide best solution.

Thank you for all the responses. I have a couple of final questions to help clarify my understanding 1) Can a fan with a timer be set to a time of 0 and 2) When installing a fan with a timer, is the wiring the same regardless of the timing being set to 0 or maximum. We are awaiting our certificates for the work. I will check on the matters raised by Toonlad in due course.
