P2590 and p2602

Hello

I found an old light controlling unit that once was build by someone I know. Unfortunately it was almost totally destroyed and I had to take it apart. It was build out a p2590 and p2602 velleman kit. Now I want to reconstruct it but I can’t find anything about the two kits. I get the basic working but don’t now what all the contact points are for. Does anybody has any information of one of these? I cant find anything on the velleman site

Thanks in advance.
