Does anyone know of a way of fitting a time delay to on to a bathroom timer fan? I.e. turn light on, 2 minute delay, then fan comes on (if light still on) and runs for the overrun after the light goes off. It’s for a windowless bathroom, to save the fan coming on every time someone quickly goes in. Thanks Graham.
i was going post this very question last week! I basically need a fan exactly as graham describes, but the ones that come with timers built in are usually pathetic. I want a big fan like they would have in a growhouse :^O JP, your 3 questions are silly. Of course some rooms have no windows, these will need forced ventilation. And a 2 min delay means you can grab a glass of water in the night without setting the fan off for the 15min overrun.
