Innensensor S2000ID Huger/ELV

Hi,

How can I adjust my inside-sensor Huger/ELV S2000ID .
The pressure has a value of zero% if its 24%
I only see one adjustable, but thats the frequency of the sender, I suppose.
No scheme’s on internet of this only manuals with some drawings. But not what I’m looking for.

Otherwise: what do I have to replace if something is false.
