To add to what Gaël posted, the Knowledge Base contains a wealth of information and guides to get you started. Within many of those guides, you will also find how-to videos to walk you through the process from A-Z. You'll probably be happy to hear that there is zero coding involved. We use drop-down boxes instead.

Since you're considering the ProfiLux (4?), this guide would be your starting point:

There's a lot you can do with the controller so take your time with it and read up as much as you can so you get the best understanding of how the system works.
