9.2 Pump stop
The pump incorporates an electronic protec-
tive 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
9.1 Control panel).
4 Pump on (green)
The indicator light is on when the pump is running.
5 Auto reset (green)
As standard, this function is activated on delivery.
• When the indicator light is on, the auto-reset func-
tion 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 func-
tion 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.
6 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.
See section 9.2 Pump stop.
The pump settings are stored.
After supply failure, the pump will
automatically revert to its previous
operating condition when the elec-
tricity supply is reconnected.
