10.2 Pump stop
The pump incorporates an electronic protective
function that will stop the pump in case of
• dry running
• overtemperature
• overloaded motor
• seized-up motor/pump.
The pump will restart automatically after 30 minutes
(for 24 hours) in case of any type of fault if the auto-
reset function is activated (the green indicator light
on the control panel is on, see point 5 in the table of
section 10.1 Control panel).
NOTICE
The pump settings are stored.
After supply failure, the pump will
automatically revert to its previous
operating condition when the
electricity supply is reconnected.
Description
Auto-reset (green):
As standard, this function is activated on delivery (does not
apply to pump versions for Australia).
When the indicator light is
• on, the Auto-reset function is activated. The pump will
automatically attempt to restart every 30 minutes after an
alarm/fault over a period of 24 hours. After this period, the
pump will remain in the alarm condition.
• off, the Auto-reset function is deactivated. The pump will not
restart after an alarm/fault.
The Auto-reset function can be activated/deactivated by
pressing the on/off button for 5 seconds.
Note: When water is consumed, the pump will start and stop
automatically, whether the Auto-reset light is on or off.

The alarm condition may have been caused by:
• dry running
• overtemperature
• overloaded motor
• seized-up motor/pump.
