Discuss Extractor fan – Is a re-wire change to change timer duration? in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
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.

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 " 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.
