Hi ben.morgan, thanks for your continued interest in my posts.
I'd just returned to the forum to post having found the same note on the same datasheet.
If anyone else can confirm that the 5017P isn't compatable with my Adam 5510EKW/TP I'd be greatful. You can be sure I'll be chasing my supplier up on the issue too. Oddly enough they can't view the forum - it's blocked on their network!
No jumpers fitted to this board, so that's correct for the voltage measurements I'm making. I wish the manual was as detailed as you are!
Time to find an alternative solution for if our suspicions are confirmed...
Best Regards.
Bandit
