Replacing batgroom extractor fan

[Rob19637]

My old fan bathroom extractor fan has broken and before I replace it a quick question.
There are Blue ,red & yellow wires connected to the old fan and the new fan has three vacant slots L (live) N (Neutral) and T ? What does the T stand for, I assume it is the correct slot for the yellow wire ?

Thanks

T = Timer.. or the run on or overrun .. whatever you want to call it..

And yes, its likely to be for the yellow wire. If it works strangely, swap red and yellow. Wont hurt it.
