Jung 48FH remote, anyone experience with it?

In my new home I have a Jung FH remote to turn on/off/dim the outdoor ceiling lighting, and to raise and lower two sun screens that are build into that same outdoor ceiling.
As I cannot easily get access into the ceiling, I am wondering if the Jung FH remote is sending signals directly to those devices, or if there must be some sort of in between switch.
In case of the latter, it could be worth it to open up the ceiling and replace those switches. But I would rather know upfront :slight_smile:
