8.2 Auto reset
This function allows the pump to automatically check if the
operating conditions are back to normal. If the operating conditions
are back to normal, the alarm indication will be reset automatically.
The factory setting is: ON
The auto reset function works as follows:
Alarm Auto reset action Configurable Default
Dry run
The pump will attempt eight restarts at five-minute intervals. If not
successful, this cycle will be repeated after 24 hours.
In twin configuration Duty/Assist, there is no reset if only one pump is
in dry run alarm. If both pumps are in dry run, the reset will be
staggered.
In twin configuration Duty/Standby, the pump will attempt to restart
immediately independent of the second pump.
YES ON
Anti-cycling
This function will attempt to reset after 12 hours, and the pump will
return to normal operation.
YES ON

8.3 Dry-running protection
If a dry-running alarm has been activated, the cause
should be identified before the pump is restarted to
prevent damage to the pump.
The unit incorporates dry-running protection that automatically
stops the pump in case of dry-running. The dry-running protection
functions differently during priming and operation.
8.3.1 Dry-running during priming
If the unit does not detect pressure and flow within 5 minutes after it
has been connected to a power supply, and the pump has started,
the dry-running alarm is activated.
8.3.2 Dry-running during operation
If the unit does not detect pressure and flow within 40 seconds
during normal operation, the dry-running alarm is activated.
8.3.3 Resetting of dry-running alarm
If the dry-running alarm has been activated, the pump can be
restarted manually by pressing [Reset]. If the unit does not detect
pressure and flow within 40 seconds after restarting, the dry-
running alarm is reactivated.
This protection is always ON.
Dry-running or water shortage.
8.4 Anti-cycling
If there is a minor leakage in the system, or a tap has not been
closed entirely, the unit will start and stop the pump periodically. To
avoid cycling, the anti-cycling function of the unit will stop the pump
and indicate an alarm. The anti-cycling function can be configurated
in Grundfos GO Remote.
Off
If the pump starts 40 times in a fixed pattern, a LED icon will
signalize cycling. The pump will remain in normal operation.
On
If the pump starts and stops in a fixed pattern, there is a leakage in
the system, and the pump will stop and show red Grundfos Eye and
LED icon indication.
The factory setting for this function is OFF.
Leakage in the system.
8.5 Maximum runtime
This function is a timer that can turn off the pump if it runs
continuously for a certain amount of time. This time period can be
adjusted via Grundfos GO Remote.
Off
The pump will run depending on the operating conditions
disregarding the continuous operation.
On
The pump will stop after the specified period of continuous
operation, and it will show the alarm Maximum runtime exceeded.
This alarm will always need to be reset manually.
The factory setting for this function is OFF.
