My guess (and it is only a guess!):

L = Mains live input
N = Mains neutral input
T = Trigger. Connect to live to start the timer/fan. This is done either by connecting T to the switched live wire to the bathroom light (so that the fan starts when you turn the light on) or by connecting a microswitch on the bathroom door between T and L

The fan motor probably connects between F (= Fan) and N. But it might be F and L, it depend on how the relay (that blue box on the circuit board) is connected.
