24i rsf-L help with room stat

[build56]

Hi I have a worcester 24i rsf-L combi
It has got a mechanical timer on it with no room stat

I want to put on a programmable room stat

Which one would be okay to go on this boiler?

Also I have looked at the boiler where the connection is and it says take the link out BUT I cannot see any link at all
I thought this boiler cannot run unless that link is in BUIT it does run all okay.

Any help PLease

You can use any that are suitable for mains voltage. If there’s no link and no room stat, then the heating will not work. Can you post a photo of the wiring?
