NOTICE
The differential pressure sensor mounted at the factory on the pump can
be operated in parallel to the differential pressure sensor at the index cir-
cuit, e.g. for heat quantity measurement on the pump. The differential
pressure sensor mounted at the factory is already configured at analogue
input AI1. The differential pressure sensor at the index circuit has to be
configured at another analogue input.
Dynamic Adapt plus (factory setting)
The control mode Dynamic Adapt plus autonomously adjusts the pump output to the re-
quirements of the system. Setpoint adjustment is not necessary.
It is optimal for circuits whose design points are unknown.
The pump continuously adjusts its delivery rate to the requirements of the consumer and
status of the open and closed valves and thus significantly reduces the set pump energy.
Dynamic Adapt plus is used in consumer circuits with variable pressure and volume flows,
e.g. radiators with thermostatic valves or underfloor heating with room-controlled actuat-
ing drives.
Hydronic balancing is required in all circuits mentioned.
In hydraulic circuits with invariable resistances, such as generator circuits or feeder circuits
(to hydraulic shunts, differential pressure-less distributors or heat exchangers), another
control mode has to be selected, e.g. volume flow constant (Q-const), differential temper-
ature constant (∆T‑const), differential pressure (∆p‑c) or Multi-Flow Adaptation.
Volume flow constant (Q-const.)
The pump controls a set volume flow Q
Multi-Flow Adaptation
The volume flow in the generator or feeder circuit (primary circuit) is adjusted to the
volume flow in the consumer circuits (secondary circuit) with the Multi-Flow Adaptation
control mode.
Multi-Flow Adaptation is set on the Wilo-Stratos GIGA2.0 feeder pump in the primary cir-
cuit upstream of a hydraulic shunt, for example.
The Wilo-Stratos GIGA2.0 feeder pump is connected to the Wilo-Stratos GIGA2.0 and also
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 in-
dividual 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.
During commissioning, all associated secondary pumps must be registered with the primary
pump so that it takes their volume flows into account. See "Settings menu – Set control
mode" [} 182] section.
Temperature constant (T-const)
The pump controls to a set target temperature T
The actual temperature to be controlled is determined by an external temperature sensor,
which is connected to the pump.
Differential temperature constant (∆T-const)
The pump controls to a set differential temperature ∆T
return temperature).
Actual temperature through:
• two temperature sensors connected to the pump.
Speed constant (n-const./factory setting for Stratos GIGA2.0 ... R1)
The speed of the pump is kept at a set constant speed.
The speed range depends on the motor and pump type.
User-defined PID control
The pump controls based on a user-defined control function. PID control parameters Kp, Ki
and Kd have to be manually set.
