Hallo!
Yes, my system supports Modbus. I have a Wolf system (CWL-2-400). The ventilation from Wolf (CWL-2-400) is identical to the ventilation from Brink (Flair 400). The Flair 400 ventilation is the successor to the Brink Renovent Excellent 400. Both the CWL-2-400 and Flair 400 now have the Modbus interface on the main board. The Modbus registers are also identical for the CWL-2-400, Flair 400, Renovent Excellent 400/300.
At the moment I am trying to control the CWL-2-400 via an RS 485 adapter and my Windows 10 PC. I use the CAS Modbus Scanner program. And these adapters:
Unfortunately the CWL-2-400 does not answer. The adapters work. The adapters work with another device that supports Modbus!
