Commissioning
*The configuration of the key lock makes it possible to protect the pump setting from
being changed. This is the case, for example, when the pump is accessed via Bluetooth
or Wilo Net via the Wilo-Smart Connect Gateway with the Wilo-Smart Connect App.
Setting of pump output
The system was designed for a certain duty point (full load point, calculated maximum
heating or cooling power demand). During commissioning, the pump output (delivery
head) is set according to the duty point of the system.
The factory setting does not correspond to the output required for the system. The re-
quired pump capacity is determined with the help of the pump curve diagram for the
selected pump type (e.g. from the data sheet).
NOTICE
For water applications, the flow rate value shown in the display or output to the
building management system applies. For other fluids, this value only reflects the
tendency. If no differential pressure sensor is installed (variant -R1), the pump can-
not indicate a volume flow value.
CAUTION
Risk of material damage!
An inadequate volume flow can lead to damage on the mechanical seal; the min-
imum volume flow depends on the speed of the pump.
• Make sure that the volume flow does not fall below the minimum value Q
Approximate calculation of Q
Q = 10 % x Q x actual speed / max. speed
