14.5 Control mode

Possible control modes:
• AUTO

ADAPT

• FLOW

ADAPT

• Prop. pressure (proportional pressure)
• Const. pressure (constant pressure)
• Const. temp. (constant temperature)
• Con. diff. press. (constant differential pressure)
• Con. diff. temp. (constant differential temperature)
• Const. flow rate (constant flow rate)
• Const. level (constant level)
• Const. other val. (constant other value)
• Const. curve (constant curve).

You can change the setpoint for all control modes, except
AUTO

ADAPT

and FLOW

ADAPT

,

in the "Setpoint" submenu under

"Settings" when you have selected the desired control mode.

Factory setting

See section

31. Factory settings

.

14.5.1 AUTO

ADAPT

The AUTO

ADAPT

control mode continuously adapts the pump

performance according to the actual system characteristic.

Fig. 36

AUTO

ADAPT

When the AUTO

ADAPT

control mode has been enabled, the pump

will start with the factory setting, H

fac

= H

set1

, and then adjust its

performance to A

1

. See fig.

When the pump registers a lower head on the maximum 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.

14.5.2 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 FLOW

LIMIT

is 25 to 90 %, of the maximum

flow rate of the pump.
The factory setting of the FLOW

LIMIT

is the flow rate where the

AUTO

ADAPT

factory setting meets the maximum curve. See fig.

.

Fig. 37

FLOW

ADAPT

Note

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