kitchen extractor fan

[bigginge]

Hi, my kitchen has an extractor fan with a humidity sensor.

It's wired so that when the light is turned on it runs and remains running until a few minutes after the light is switched off.

The humidity sensor also runs the fan regardless of if the light is on or off.

Is there any way I can stop the fan running when the light is on. It's annoying when sitting in the kitchen and as the fan will run automatically when humidty rises I don't see the point.

disconnect the switch wire. but do put it in a choc block and label it
