I had an axial fan with a LS in my bathroom that just was not up to the job, so I bought an in-line fan but ordered the wrong one, I ordered one without a timer so only has neutral and live connectors in the fan and no LS.
The cable that comes from the light switch and fan isolating switch for the bathroom is a 4 wire cable, earth ( not used as all plastic components) brown, black and grey. As per the attached photo, I have connected the brown wire to the live connector of the fan and the grey wire to the neutral connector, this turns the light switch on and off but not the fan, the fan works by the isolating switch, manually and not when the light comes on. So what do I need to do to the black wire to switch the fan on when the light switch comes on (not bothered with the fan staying on for a minute or so after switching light off)
Thanks in advance
