9.3 Mode of operation

A LED provides information about the operation status of the circulator.
LED COLOR DESCRIPTION
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.
Violet

P mode (∆p-v) – Proportional differential pressure
The circulator head is proportionally reduced at falling water
demand and increased at rising water demand.
The circulator head is proportionally reduced with decreasing of
Green
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).
C mode (∆p-c) - Constant differential pressure
The circulator maintains a constant pressure level (head)
Orange
irrespectively of the heat demand required from the heating
system (flow rate).
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.
Blue
Should this performance be insufficient, progressively increase
the set value. Should this performance be excessive or should
noise arise due to the speed of the pumped fluid, progressively
reduce the calibration.
Flashing Automatic detection of the presence of air.
