Extractor fan connection

Hi,

I hope you can help me please. I am replacing extractor fan with timer and PIR (100TM model) to model 441625A (100T) with just the timer. With the old one (the one with orange drawing) 3 wires are connected in the same order Ls,N, L (L at the bottom) and all works fine. It is activated on movement (movement only, pulling a light string without movement in the bathroom does not activate fan), then switches itself off after specific time.
Now I have connected the new one which has the same marking Ls at the top, then N and L. Unfortunately new one works constantly without stopping. At first I thought timer is not working and got replacement. However replacement has the same symptoms. As you notice 3 wires on the right are plugged in the same way however new fan has cable coming out of top left unlike the old one. I have also attached a photo of the inside of the socket which we can use to switch on and off fan manually.
Could you help me to work out if indeed timer is broken on both extractors or simply this type of wiring can't support the timer on a new fan for some reason. I just can't understand why one can switch itself off (old ones) but new ones can't.
Attached diagram is a wiring schematics for the new fan.
Any assistance would be highly appreciated please. Many thanks for your time.
