Wiring TT 100T Fan for Twin Speed use Ask questions and find answers to many subjects relating to electrics and electrical work

[Woodlej]

We currently have the TT 100T wired to use max fan speed but would like to change it to allow the use of both min & max speeds. This is possible according to wiring diagram in user manual but requires 4 cores. My question is then how would this be isolated as I can’t find a suitable fan isolator switch

Why could you not use a conventional isolator to isolate the supply (Live and Neutral) to the fan?
