Bathroom Extractor Fan

[mobad]

Just had the following extractor fan fitted for my bathroom, recommended by my electrician.

Based on the manual it states the fan should be triggered by the relative humidity % however since installation this morning, it has been continuously on.

I have spoken to the electrician whom advised it is made to stay on all the time.

Am I misreading/misunderstanding the manual?
I have set the humidity to 90% to test the threshold however it still stays on...

He may have wrongly wired it but maybe more likely it is faulty. If you can do so safely post some pics.

Yes, it should be mandatory to double post

That is consistent with screwfix advice about being permanently on, the problem is what manufacturers say is whisper quiet isn’t always what it seems

Problem with humid stat fans is that they can take a few days to settle down.
