Q&A – Setting Up and Wiring Extractor Fans In The Home.

Please note – These are the most common questions that our customer service team are asked on a daily basis about extractor fans. Some of this information is given to aid understanding of some of the most common fan wiring issues – We would always recommend that any wiring in the home is done by a suitably qualified electrician as there are very real dangers and stringent laws associated with the majority of electrical work.

Question: I bought a timer fan to replace a standard fan, why won’t it work?

Answer: Usually this due to the original standard fan only having a single live connection. Most timer fans (and fans with other automated options such as humidistats and PIR sensors) require an additional permanent live cable to make the timer function work. This type of fan uses a switched live to activate the fan on first use and then when this circuit is broken (i.e. the fan is switched off with the light for instance) then the other ‘permanent’ live provides a feed to the fan in order that it can run on for the duration that the timer has been set to. The fan cannot be used, unless the extra live is provided or the time function is completely linked out (see below).

There are some exceptions to this rule, for example the Airflow Quietair timer, humidity and sensor fans will work without the additional permanent live its just the over-run timer won’t function.

Question: How can I get my timer fan to work when I only have 1 live cable and a neutral?

Answer: Most timer fans can be fitted to a circuit with only a single live if the permanent and switched live terminals on the fan are ‘linked’. This will allow the fan to run in a straight forward on/off operation only, the timer will not activate. This should only be attempted by an electrician after first consulting with the manufacturer of the fan.

Question: I have just had my humidity fan installed and its continuously running and it wont turn off

Answer: Most humidity controlled fans leave the factory with the adjustable humidity stats  pre-set (sometimes as low as 40% RH), it may well be the humidity in the area that you live in is higher than the factory setting thus resulting in the fan running continuously. Simply increase the humidity stat setting to the required level of relative humidity. We advise starting at full (usually 90%) and working back down in small increments until you are happy with the fans response to turning on the shower etc. Please also be aware that unless your house is completely 100% sealed, then increases in external humidity levels during the year will also have an effect inside your house, so you may need to adjust the fan setting every 6 months or so.

Question: How do you wire a fan so that it comes on with the lighting circuit?

Answer: Pretty much any extractor fan (continuous running fans are usually set to run at a very low speed when the light (or remote switch) is off can be wired to be switched on/off at the same time as the light in the room. In simple terms, the light source is wired between the ‘switched live’ and the ‘neutral’ on the input side of the fan (or more likely the fan isolation switch to comply with regulations).

Question: Are 2 Speed (or multi-speed) fans more difficult to wire?

Answer: Not necessarily, but you do have pay close attention to the manufacturer’s wiring diagrams. You have a choice of terminals to wire to for one speed and another set for the higher speed. The complications can arrive if you wish to be able to externally switch the fan between speed 1 and speed 2. This will usually require the wiring in of an additional switch that will alter the speed (with a separate pull cord for example switching the fan on/off). It is also possible to buy a 3 position switch that has a centre off and then a speed 1 and speed 2 setting so that fan can be controlled from just one switch. You can further complicate things by adding a lighting circuit and timer facility. This is why qualified electricians have to spend a long time in the classroom and on courses learning all the possible permutations and how to confidently read some of the more complicated wiring diagrams. It is also worth noting that ‘having a stab’ at the wiring of extractor fans can not only be dangerous but also risks damaging the fan circuitry, so that when its eventually re-wired correctly it may still not work.

Question: How are Continuous or DMEV fans used?

Answer: Continuous running fans are usually set to run at a very low speed when the light (or remote switch is off) and then go into ‘boost’ mode (higher fan speed) when the circuit is activated. In continuous mode, the fan provides gradual replacement of air very quietly and with a small amount of energy. The boost function helps to remove humidity and stale air when a room has been recently used for showering, bathing, tumble drying etc..

Question:  How do I keep fan noise as low as possible?

  • Pick a fan with a low decibel levels (Vent Axia Silent, Airflow Quietair etc..)
  • Be aware that fully tiled bathrooms can act as an amplifier for any noise present.
  • Use an in-line fan in the loft or void if possible (Airflow Aventa, Vortice Lineo etc..)
  • Use the lower fan speed setting on in-line mixed flow fans as often high speed is over kill in standard sized bathrooms
  • Cushion the fan mountings – Many contractors use cut up pieces of mouse mat under the in-line fan mountings to reduce vibration noise transferring through the joists.
  • Extreme noise reductions – Its not uncommon for in-line fans to be ‘wire suspended’ in some lofts so that vibration issues are taken out all together.
  • Consider using acoustic, insulated ducting.

Best Looking (Designer) Bathroom FansVent Axia – Xpelair – Vortice – Airflow – Greenwood Airvac – Silavent – Domus

The phrase ‘Number One Fan’ if you are a Stephen King reader, may mean something quite sinister but in our line of work the phrase is an exciting challenge.  To find the best fan on the UK market is impossible simply due to the sheer choice of quality extractor fans available.  There are countless ‘number one fans’ available and their ranking is only defined by what each and every individual user hopes to achieve from the installation of their fan of choice.

Extractor fans are hardly new, they have been around for decades but we are fortunate now to have a group of major fan manufacturers who not only are brilliant at the basics, i.e. ensuring that the manufacture of the fan maintains its ‘fit for purpose’ classification and that the design of the fan meets even the most stringent aesthetic design expectations of today’s demanding consumer.

There are several ‘brand leaders’  in today’s market, each one bringing years of product design and development to the fore and each specializing in a different yet no less important aspect of fan design and functionality.  In addition, historic research and development undertaken by these companies has made them more keenly aware of the advantages gained by being aware of potential changes in Building Regulations, Statutory Requirements or market trends.  This awareness drives them to constantly expand existing ranges and develop their new and potential products in such a way that the consumer will always have a choice of the best possible range of fans to meet any requirement.

Vent Axia, offer a huge range of fans ranging from a highly efficient basic extractor fan right through to a sophisticated low voltage, design conscious fan also capable of being used in wet rooms with timer and humidity options.   It was way back in 1936 that the first electrically operated window fan was developed and Vent Axia was born.  Today they are as forward thinking and committed to ongoing product development as ever and their forward thinking philosophy means they constantly strive to maintain their position as leaders and innovators in the lo-carbon and energy saving fields of design.  The brand is trusted world-wide and their consistent commitment to innovation and excellence is universally recognised.

I first entered the world of Electrical Wholesale 15 years ago, and the demand at that time, for extractor fans was generally focused on who could supply the cheapest, regardless of performance! Today, with a clear customer demand for powerful and effective Bathroom extractors, Humidity controlled fans are as popular as ever, as they are seen as an automated method for managing moisture within the Bathroom.

Here on the Fastlec Blog we have covered the issues around correct setting of Humidity Control before, but this summer a new issue raised its head. A client from the London area contacted us to say that her Vent Axia Humidity fan, which had been fitted at the beginning of the year, was now running continuously. A quick chat with the Vent Axia Technical Department, and one of their helpful staff revealed that it was most likely due to an exceptionally high Humidity level in the UK at that period.

Sure enough, Vent Axia Humidity Controlled fans come factory set at 72%, a quick check on Google, Humidity in London that day, 75%! The client just needed to increase the Humidity setting to around 80% to avoid this nuisance switching and return it once the humidity levels had dropped, simples!

Oddly enough, I have just checked the Humidity levels in London at present (a Wet and Cool afternoon on the 28th September) and its 82%!!! I can almost hear those Vent Axia fans running in chorus.

If you want to know more about setting Humidity Fans, which includes the often counter-intuitive dial settings (turn it all the way down and it stays on, turn it all the way up and it stays off) take a look at our earlier blog post Troubleshooting The Airflow iCON HTM Humidity Module.

It is now widely accepted that an extractor fan in a kitchen, bathroom or en-suite is an essential, not a luxury.  It reduces condensation and eliminates damage to the décor of a room and also helps prevent damage to the fabric of a building caused by humid air being retained in a room.

The key word here is décor.  If you have spent a lot of time and money designing and decorating the most logical next step would be to install an aesthetically pleasing extractor fan which would blend in or enhance your home.

Fortunately, several forward thinking manufacturers have introduced models to their range which have continue reading…

The Kitchen Extractor Fans are included in our comprehensive extractor fan range, and many of these could be successfully installed and employed in a kitchen.

Deciding which one to go with can be a daunting process and to help make the choice easier for the majority of customers we have brought together continue reading…

Aiflow Icon Iris Grille

The Iris is opened by an actuator that is fixed to the main body of the fan, as a result, if the cover is not properly located on the base, this will cause it not to open. To identify the problem, simply remove the cover and follow this procedure:

Place the cover onto the mounted base, with the cover turned anti-clockwise by about an inch, this should firmly locate and then allow you to turn the cover clockwise to lock into place with the icon oval emblem in the centre at the bottom. You will know you have located it correctly because the grub screw will fasten up correctly and hold the cover from turning.

If following the above, the iris does not open after the fan has been running for approximately 60 seconds (the fan does have a delayed opening shutter) then the actuator may be faulty and the complete fan will need replacing.
