Has anyone connected a Swegon ventilation unit to QJ71MB91.
At Swegon, Read Holding Registers is 03 and in GX 0500. 03 is not in GX.

I can't make it work.

ok lets see you are refreshing D3000 to D3100

Holding Register 30 should go to D3000 (In you're text you're talking about holding register 3 ??)
you are only reading this Device could be a +1 issue. 

Is communication working (no exception errors)?
