Bathroom Fan Control by Timer or Clock Ask questions and find answers to many subjects relating to electrics and electrical work

[mrchriz82]

Is it possible to hook up a bathroom timer fan to some kind of clock?
I wish to prevent the fan coming on at certain times of night to prevent it waking people up.

Generally the standard method would be a three pole isolation switch that can be put in the off position.

But it could be possible to have a 24hr clock timer attached to the fan conductors, to turn off on any evening.
