I didn't try to contact them yet, not regarding documentation. My employer did, and they are looking for someone to send in, but since this is not the most popular system here on the island, could take some time.
As to control panel, I don't want to play with it without a manual in hand.
I didn't got any prints yet from #arsjon so if anyone have something regarding one of those, please email it to me.
That would be great if you had a code book to this.
