Hello Guys, I have a Viessmann 100 W Combi Boiler and a Wiser Multi-room Kit 1 connected to it via Opentherm. The system works well, but the eco mode is no longer available when in Opentherm mode. Always does a pre-heat , any idea to shut down eco mode ? Already talked with the service in Hungary - they said doesn’t want to help to solve the issue because 3rd party OT control not supported...... 😞 Thanks in advance, Joe
