Set the time, over 24 hours, the pump must be stopped. Default 45 minutes. If this
time is exceeded the display shows "leaks". In the sixth event (fixed number), the drive
stops completely. Must be turned off, check the status of the system by eliminating the
losses, if any. Parameter needed to diagnose problems of the drive to stop.

Varie
Counts the number of times the continuous pump operating time exceeds the hold
time t0 Pump Off (par 58). By default, so as not to increase the number of leaks, the
pump must not operate for at least 54 mins within a 24 hour timescale. If the "leaks"
message appears, check whether there are leaks in the system or check times and
settings.

Varie
Displays the time elapsed (timer) in the alarm and no water or insufficient pressure.
In the absence of flow with a frequency greater than 45Hz, the timer is incremented.
MMA Version: power less than the value set in par (54) and higher frequency at 45Hz.
MMW Version: Flow valve closed and a frequency above 45Hz.
