Specific EEI values
To avoid condensation in the stator, the liquid temperature must
always be higher than the ambient temperature.
10.1 Reduced supply voltage
The pump operation is ensured above 160 VAC with reduced
performance.
If the voltage falls below 190 VAC, a low-voltage warning is sent via
the PWM signal.
If the voltage falls below 150 VAC, the pump stops and shows an
alarm.
