Another humidstat fan question

[tnotty]

I've replaced an old extractor fan with a xpelair humidstat with timer. The spur runs from the lighting circuit and used to have a manual pull cord but as this is a humidstat fan I have no need to use the pull cord so it now spurs directly to the fan terminals (L,N,E) .
All works great but wondering if I need any isolator?

In my opinion I don't as humidstat turns on when steamy only so this suits my need perfectly. But is this correct or should I put an isolator in the loft?
Thanks

The isolator is meant to be used to isolate the fan for maintenance purposes, rather than a functional on/off.
That's why fan isolators break all three live connections: line, switched line and neutral.

Thanks for the info. So is it fine to put one in the loft to save running long lengths of cable to put it above a door?
