Humidity and Odour Extraction from Bathroom

[adrian.groves]

I currently have a an in line duct fan controlled by a humidistat in my bathroom and it works well, extracting the air when I have a shower.

Unfortunately the humidistat cannot tell when there is an unpleasant odour in there and I have been looking for another way to switch the fan on for 5 minutes or so.

Is there such a thing as a switch with timer that I can use to just press/pull when I need that 5 minutes of extraction? I do not really want the fan to come on every time I use the light.

thanks.

Hi, yes is the short answer ! You could bridge out the humidistat with a switch. The easy option if you can locate the switch outside the bathroom would be to fit a time-lag switch(the type used on stairwells) which has a mechanical push which releases over a set time.

Come on people, this is 2016. Time to use technology…!!!

Thanks for the rapid responses, I will use a timer switch outside of the bathroom. I had a search on-line to see if there is a pull switch version but could not see one, hence I think the second option from TLC will look nice.

I like the sound of the appropriately named Raspberry Pi, but it looks to be beyond me!

but is has a minimum load of 40W.

I think you may have problems!

40W, or for wiring in parallel 40W per time lag switch in the circuit. Load capacitors (order code LOAD CAP) can be supplied to augment small loads

Only the electronic one. The vacuum one will be OK.
