If the preset value maintenance time is set as zero, PID control will be conducted upon taking the
preset value as the initial value of the integrator. It corresponds with the preload of PID and is
used to improve the response speed at the startup stage.

0: Water supply function is not selected
1: Common PI-regulated constant-pressure water supply
2: Water level control
3: Pumps are started on by one in the sequence based on water pump capacity
4: Firefighting water supply
When
F8-00=1, common PI-regulated constant-pressure water supply will be effective.
The
inverter samples from pressure signals and adopt PI regulator calculation to determine the output
frequency of the inverter. Thus the rotation speed of the water pump is adjusted to realize
constant pressure water supply. If any firefighting operation command is inputted, the water
