Time for added pumps speed arrival max: when command for adding pumps being sent, a
delay(H00.08 parameters) been start, which makes the pump arrive at its rated speedbefore start
another pump(avoid shaking).
Time for reduced pumps zero-flow: when command for adding pumps being sent, a delay(H00.09
parameters) been start, which makes the pump can stop effectively before stop another pump(avoid
shaking).

This function mainly use for protection inverter and AC power supply from short-circuited, which
caused by contactor action delay when a motor switched from variable frequency to power frequency.
Set the shortest time larger than the total of relay action time and contactor action time, generally
the contactor action from connect to disconnect takes longer time than switch from disconnect to
connect, please operate on longer time.

running time longest one when reduce pumps.

Single variable pump, with assisted pump switched, timing rotate. When 2 pcs or
more than 2 pcs assisted pumps running at the same time, if system meets the term of reduce
pumps, the firstly started pump will stop first; if the one of them keep running more than H00.13
(timing rotate gap), the assisted pump stops, and start the pump with longest stop time. (2) Multi
