6.1 Operating modes
Normal
The pump runs according to the selected control mode.
Stop
The pump stops.

Min.
You can use the minimum curve mode in periods in which a
minimum flow is required. This operating mode is for instance
suitable for manual night setback if automatic night setback is not
desired.
Max.
You can use the maximum curve mode in periods in which a
maximum flow is required.

6.2 Control modes
6.2.1 Radiator mode
If the pump is placed in a two-pipe radiator heating system, we
recommend that the pump operates in "Radiator mode".
The radiator mode uses the AUTO
ADAPT
function to automatically
adjust the pump performance to the actual heat demand in the
system. The pump performance follows a proportional-pressure
curve within the AUTO
ADAPT
range,
which is anywhere between
the maximum and minimum proportional curve.
For further information, see section

6.2.2 Underfloor mode
If the pump is placed in an underfloor heating system, we
recommend that the pump operates in "Underfloor mode".
The underfloor mode uses the AUTO
ADAPT
function to
automatically adjust the pump performance to the actual heat
demand in the system. The pump performance follows a
constant-pressure curve within the AUTO
ADAPT
range, which is
anywhere between the maximum and minimum constant curve.
For further information, see section
.

6.2.3 Radiator and underfloor mode
If the pump is placed in a system that consists of both radiator
and underfloor heating, it is possible to select a combination of
the two, called "Radiator & Underfloor mode".
The mode uses the AUTO
ADAPT
function to automatically adjust
the pump performance to the actual heat demand in the system.
The pump performance follows a proportional-pressure curve
within the AUTO
ADAPT
range, which is anywhere between the
maximum and minimum proportional curve.

The pump is factory set to radiator mode.
If operating in a one-pipe system, the pump must be
set to constant pressure. See section
