Parameter 710 is only to be set, when operating
mode 9-14 is selected.
The adjustable speed pump typically runs at maximum
speed when staging on an additional fixed speed
pump to match the system demand. When staging on
another pump, the VLT will coast and after a time delay
set i par. 710, the pump will be switched to mains. The
VLT will finally bring the next pump in line up in speed.
