PDM20 Series

If you hope that the SPD can start automatically after time delay set by P0.15 at
power on, after setting all parameters, make P0.14 = 11 to enable auto-start
function of the SPD. Every time at power on or fault reset, it will start
automatically.

When it is set as 0, it keeps
running at anti-freezing running
frequency
Set P0.16=1 to enable anti-freezing function. The SPD will adjust the running
frequency of pump according to current status after it is started.
Note:
Pump auto-adjusting given frequency is prior to anti-freezing frequency.
Anti-freezing frequency can’t be set to high. It should be set as the frequency
that can just drive the pump but can’t supply pressure.
P0.20
Water leakage
coefficient
0.0～100.0
2.0
The bigger the water leakage, the bigger
the coefficient.
In no water consumption, because of water leakage of pipe network, the SPD can’t
sleep and stop. It starts and stops frequently. To solve the water leakage problem of
pipe network, modify the value of P0.20 according to water leakage. The bigger
the water leakage, the bigger the coefficient.
