Fig.8: Setpoint depending on the volume flow
1 Reference setpoint
2 Setpoint in the event of zero flow
3 Maximum volume flow per unit
Please see Fig.6 for typical default values for the setpoint at zero flow.
Procedure (example: SiBoost Smart 3Helix VE604):
• Based on the reference setpoint (1), the curve to be used is selected (here: 5bar).
• The point of intersection between this pump curve and the maximum volume flow of
the system (2) (here 3x6=18m³/h) is used to determine the relative setpoint at zero
flow (3) (here 87.5%). Link not working: See also https://app.wilo.com/Standalone/

Fig.9: Typical default values for the setpoint at zero flow
1 Reference setpoint
2 Maximum volume flow per unit
3 Relative setpoint in the event of zero flow
NOTICE
To prevent an inadequate supply, the setpoint at zero flow must be
greater than the geodesic head of the highest tap.
