Our most frequently asked questions

• And what about the neighbors in the morning? The valves are controlled as on the original: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.
