PFC applications

Several PFC (pump and fan control) solutions are possible. Below you will see an overview of two typical configurations. PFC solutions are recommended for all systems where the demand varies much over time.

Standard PFC

In the PFC mode the frequency converter uses the internal PID regulator to control pressure or output flow. In case a higher capacity is needed, the converter can start auxiliary pumps which add to the total pumping capacity. Included in the default "All in One" application package and in the NX Light Multi-Control Application.

PFC with Autochange

In PFC with Autochange mode the converter can define which pump takes the control and which pumps are auxiliary pumps. The pumps are alternated automatically by the frequency converter, guaranteeing equal usage of the system in all load situations. Included in the default "All in One" application package and in the NX Light Multi-Control Application
