GFAN412T Time adjust

[BigMark61]

I have the GFAN412T fan in my bathroom and when I switch it off the timer runs on for a very long time afterwards.
can anyone tell me how to adjust the timer settings on it.
Cheers and Kind regards

Is there no obvious adjuster on the transformer?

Cheers for replying
There is a large white plastic screw head with a +/- on the transformer, so is that where the timer is I thought it would be on the fan itself.?

That will be it - it is the transformer, of course, which has the permanent and switched live supply, so it is the transformer, of course, which contains the timed-overrun circuitry. All the fan has is a 12V motor.

To have the timer in the fan would require a ridiculous amount of complexity in signalling and require more cabling between the transformer and the fan.

If your bathroom contains a shower, you will want that fan to run on for 20-30minutes to ensure sufficient ventillation
