(*) If these two errors occur, check the pressure indicated on the water gauge. If the pressure is insufficient (< 0,4 bar, red area), proceed with the filling
operations described in the chapter "Filling and emptying the systems".
If the system's pressure is sufficient (> 0,6 bar, blue area) the malfunction is caused by a lack of water circulation. Contact the Technical Assistance.
