The pump settings are stored. After supply failure, the pump will automatically revert to its
Note
operating condition when the power supply is connected again.

5.2 Pump stop

The pump incorporates an electronic protective
function which 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 in section 5.1 Control panel).
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.
• When the indicator light is 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.
Alarm (red):
The indicator light is on when the pump is in alarm condition.
The alarm condition may have been caused by:
• dry running
• overtemperature
• overloaded motor
• seized-up motor/pump.
