Multi-Flow Adaptation

The volume flow in the generator or feeder circuit (primary loop) is adjusted to the volume flow in the consumer circuits (secondary loop) with the Multi-Flow Adaptation control mode.
Multi-Flow Adaptation is set on the Wilo-Stratos MAXO feeder pump in the primary circuit upstream of a hydraulic shunt or a heat exchanger.
The Wilo-Stratos MAXO feeder pump is connected to the Wilo-Stratos MAXO pumps in the secondary circuits with Wilo Net data cable.
The feeder pump continuously receives the respective required volume flow from each individual secondary pump at short intervals.
The sum of the required volume flows from all secondary pumps is set by the feeder pump as the setpoint volume flow.
To adapt the supply to local conditions, a correction factor (80 – 120%) and a fixed volume flow rate can be set. The fixed volume flow percentage is always calculated for the calculated volume flow.
On commissioning, all associated secondary pumps must be registered with the primary pump so that it can take their volume flows into consideration. For more information on the installation and operation of Multi-Flow Adaptation, see the “Setting up Multi-Flow Adaptation” section.

NOTICE

The Multi-Flow Adaptation application can only be used in systems where the primary loop is separated pressure-free from the secondary loop by means of a heat exchanger or hydraulic shunt.

NOTICE

When replacing a Stratos MAXO pump with SW ≥ 01.04.19.00 in an existing Multi-Flow Adaptation system with pumps that have a lower SW version (SW < 01.04.19.00), all integrated Stratos MAXO pumps must be updated to a higher SW version (SW ≥ 01.04.19.00).

For pumps with a SW version (SW ≥ 01.04.19.00), it is not strictly necessary for the primary circuit pump and the secondary pumps to have the same SW version.
