Hi,
I have an old multiplus 24/2000 with the old CPU which I want to controll using a VE.Bus smart dongle. However this needs a firmware version >400. Is it possible to change the main controll board to a new CPU or to downgrade the smart dongle firmware to be compatible with a version 200 firmware? I did not get any useful answer from my distributor yet.
Thanks for your help
Best Leo
