Most frequently asked questions

• What about the neighbors in the morning? The valves operate as on the original system: closed and discreet 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 usually fits it in one to two hours.
