2: Operation Mode
To further improve the energy saving effect function.Normal operation is to use one driver as the main controller and only one pump in PID control variable frequency mode. The average distribution operation mode is an operation mode in which all linked pumps distribute the total output rate to all linked pumps according to the PID control method. The average distribution mode operation function can only be used when the diameters of the system pipes are the same, and it has the advantage of preventing the main driver from running continuously for a long time.
