It sounds like your replacement fan lacks an inbuilt timer.

I hope you made a note (by looking at how the terminals on the old fan were marked) which is switched live, permanent live and neutral...

You haven't bought the same type of fan. You can use it - you'll need to make the unused permanent live safe in a piece of choc-block, but the fan won't stay on after the light is turned off, so it may end up not being any use.
