Bathroom fan control; beginners question

Dear forum guys,

I would like to know how to solve the following “challenge”.
fan now works with timer activated by lightswitch. (3 minute turn on delay) 15 minute turn off delay.
Problem: when my girlfriend is resting in the bath she realy hates the noise of the fan…
So I’m looking for a solution as follows:

  1. turn on light
  2. if light is on longer than 5 minutes
  3. switch on fan when light is turned off.
  4. otherwise leave fan off.

how to do with with what kind of kit (if possible)?

Thanks in advance for your reaction(s)

best regards,

DubbelJoe

I was realy hoping to get a reply on this… Is my story clear or did the people that red the post missed information?

Thanks in advance again!

Little chance you will get an answer.
This is not possible with a standard kit or kits.
You will need to develop a custom circuit.

Oke,

Clear answers don’t always mean good news… So it is back to the drawing board for me.
Thanks for the reply.

Best regards,
