I have called with Homematic support and they confirmed etrv2 can communicate directly with WHS2 element without need of CCU3. They have also mentioned set-up of WHS2 is described in manual in app (only in german, but on homematic web page also in english..
They have also confirmed WHS2 is capable of potential free (non potential) boiler management
