I just bought a second jebao mlw-20 and put it in master/slave modes, but the master for the slave changes only the modes according to the schedule, but not the speed, and when the slave is configured, this parameter is constantly adjusted. Then what is the point of doing master/slave modes, if the flow on the second pump will always be the same. Either I don't understand something correctly or tell me what can be done. Or there is no solution to this and it is worth putting the same program on each pump without master/slave
