Hi Fionn
It's an old V4 controller you have.
I can recommend to replacing it with a V7.
It is a much more modern and up-to-date mcontroller, with a lot of new features.
NBE has no dealers in Ireland, but I wonder if we can't find a dealer in Denmark who will send a control to you.
Hedestoker is one of the major dealers in Denmark, you can try to contact them.
