The pressure in the pipe will remain constant when we have no flow. However, with flow, the pressure will drop farther down in the pipe. This can be compensated by raising the setpoint as the flow increases.

Selection 1, Enabled: If the regulating motor needs to be included in the auto-change or interlock logic make the connection according to Figure 37 below. Each motor is controlled by a relay, but the contact logic ensures that the first connected motor is always connected to the drive and near the mains.
