• Constant curve.
Setting:
1. Select control mode with or .
2. Press [OK] to enable.
The setpoint for all control modes, except AUTO
ADAPT
and
FLOW
ADAPT
, can be changed in the "Setpoint" submenu under
"Settings" when the desired control mode has been selected.
All control modes, except "Constant curve", can be combined with
Automatic Night Setback. See section 13.5
Automatic Night
Setback
.
The FLOW
LIMIT
function can also be combined with the last four
control modes mentioned above. See section 13.4 FLOW
LIMIT
.
13.3.1 AUTO
ADAPT
The AUTO
ADAPT
control mode continuously adapts the pump
performance according to the actual system characteristic.
Fig. 21 AUTO
ADAPT
When the AUTO
ADAPT
control mode has been enabled, the pump
will start with the factory setting, H
fac
= H
set1
, corresponding to
approx. 55 % of its maximum head, and then adjust its
performance to A
1
. See fig. 21.
When the pump registers a lower head on the max. curve, A
2
, the
AUTO
ADAPT
function will automatically select a correspondingly
lower control curve, H
set2
. If the valves in the system close, the
pump will adjust its performance to A
3
.
The AUTO
ADAPT
control mode is a form of proportional-pressure
control where the control curves have a fixed origin, H
auto_min
.
The AUTO
ADAPT
control mode has been developed specifically
for heating systems and is not recommended for air-conditioning
and cooling systems.
To reset AUTO
ADAPT
, see section 13.9.8 Return to factory
settings
.
13.3.2 FLOW
ADAPT
When FLOW
ADAPT
is selected, the pump will run AUTO
ADAPT
and
ensure that the flow never exceeds the entered FLOW
LIMIT
value.
The setting range for the FLOW
LIMIT
is 25 to 90 % of the Q
max
of
the pump.
The factory setting of the FLOW
LIMIT
is the flow where the
AUTO
ADAPT
factory setting meets the max. curve. See fig. 22.
Fig. 22 FLOW
ADAPT
13.3.3 Proportional pressure
The pump head is reduced at decreasing water demand and
increased at rising water demand. See fig. 23.
The setpoint can be set within the range from 1 meter (3.28 ft) to
approx. 1 meter (3.28 ft) below the maximum head, depending on
pump type.

Note
The operating mode must be set to " Normal "
before a control mode can be enabled.

Manual setting of the setpoint is not possible.
