I recently bought a "SwiftAir STY!00H" extractor fan (built-in humidistat and run-on timer) to replace an old extractor fan that is connected to a twin and earth, where the live comes from the switched live of a ceiling pull switch. I would like the new fan set up so that the pull switch is always "on" and let the humidistat turn the fan on and off. (I'll keep the ceiling pull as an isolating switch).
The fan has L/N/SL connections, so I assume I need to connect the existing T&E to the N & SL. But I'm not sure what to do about the L terminal, as there is no permanent live available (without getting into the loft and running one in).
Does the permanent live have to be connected, or is this is only needed for the timer run-on feature (which I'm not bothered about)? If it *must* be connected then could I just run a jumper between SL and L?
