9.3 Mode of operation
A LED provides information about the operation status of the circulator.

DESCRIPTION
Violet
ActiveADAPT mode
The activeADAPT mode enables the circulator to actively
adapt its performance to the demands of the system during
short control intervals inside a defined control area.
• Improves the hydraulic balance of the system
• Ensures optimum performance during partial load periods
• Enables quick installation
Green
P mode (∆p-v) – Proportional differential pressure
The circulator head is proportionally reduced with decreas-
ing of the heat demand from the heating system (flow rate
decrease) and is proportionally increased with increasing
demand of the heat demand from the heating system (flow
rate increase).
Orange
C Mode (∆p-c) - Constant differential pressure
The circulator maintains a constant pressure level (head)
irrespectively of the heat demand required from the heating
system (flow rate).
Blu
min-max mode – Fixed speed
The circulator maintains a fixed speed irrespectively of the
heat demand from the heating system (flow rate).
The speed regulation is done by positioning the selector in
a gradual manner at any point between the Min and Max
positions.
Should this performance be insufficient, progressively in-
crease the set value. Should this performance be excessive
or should noise arise due to the speed of the pumped fluid,
progressively reduce the calibration.
