Where:
P = XXX W is the current power supplied to the pump
T = XX °C is the current temperature of the pump
XXXX Hz is the driving frequency of the pump. This value is set
by default to 1167 Hz but can be modified by the user according
to needs, proceeding as described in the "PROGRAMMING"
paragraph. The unit of measurement (HZ / Krpm, default = Hz) is

performed. On completion of the soft-start ramp, the bargraph is
replaced with indication of the frequency of rotation of the
pump
Pressing twice, the following is obtained:

Where:
NORMAL: indicates the pump status
XXXHz: is the driving frequency of the pump (for further details
please see the description "Pressing once" the Measures key)
I=X.XXA: indicates the current absorbed by the pump
V= XXX V: indicates the pump driving voltage
Pressing 3 times, the following is obtained:
