So what's the normal way of doing things? If I connect to operate from the light switch then what about in the daytime when you use the shower and wan t the extractor running but don't need the light on? Is it just expected th at any time you use a shower you must have the light on no matter the time of day?
And as the regs require this ventilation when the shower is in use surely t here's no point operating the extractor from a light switch because then it doesn't have to be used.
All seems odd to me and as I said...I'm confused.
