Fig. 37: Control functions
Differential pressure ∆p v (factory setting for Yonos GIGA2.0)
The control changes the differential pressure setpoint to be maintained by the pump lin-
early between reduced differential pressure H and H
The controlled differential pressure H decreases or increases with the flow rate.
Differential pressure Δp-c
The control keeps the differential pressure generated by the pump constant over the per-
missible flow rate range at the set differential pressure setpoint H
characteristic curve.
Starting from a required delivery head to be set according to the design point, the pump
variably adapts the pump capacity to the required volume flow. The volume flow varies due
to the open and closed valves on the consumer circuits. The pump output is adjusted to the
requirements of the consumer load and the energy requirement is reduced.
Constant speed (n-c / factory setting for Yonos GIGA2.0 ... R1)
The speed of the pump is kept at a set constant speed. The speed range is dependent on
the motor and pump type.
User-defined PID control
The pump controls based on a user-defined control function. The PID control parameters
Kp, Ti and Td must be specified manually.
The PID controller used in the pump is a standard PID controller.
The controller compares the measured actual value with the specified setpoint and at-
tempts to match the actual value to the setpoint as closely as possible.
Provided the appropriate sensors are used, various controls can be implemented.
When selecting a sensor, attention must be paid to the configuration of the analogue input.
The control behaviour can be optimised by changing the P, I and D parameters.
The direction of control action can be adjusted by switching the control inversion on or off.
