If the alarms A01 and/or A11 are triggered, an attempt is automatically made to restart the
pump unit:
• After 5 minutes
• If the alarms persist, every 30 minutes over the next 24 hours.
If the alarms continue to persist, the pump unit remains off with the LED (11) on.
Note: the alarms can be reset at any time by pressing the MENU/ENTER button (6).
