Parameter Description
Illustration 3.44 Flow Compensation
NOTICE
When flow compensation is used with the Pump
Controller (parameter group PC-##), the actual setpoint
does not depend on speed (flow), but on the number of
pumps cut in. See Illustration 3.45:

AP-80 Flow Compensation
Option: Function:
[0] Disabled Setpoint compensation not active.
*
[1] Enabled Setpoint compensation is active. Enabling this
parameter allows the flow-compensated setpoint
operation.

There are 2 methods which can be employed, depending
upon whether or not the speed at system design working
point is known.
