Pump Control
The circulation pump can be controlled:
• internally without a PWM signal by selecting a suitable mode and pump performance curve
• by an external PWM A control signal (prole for use in heating systems) or PWM C control
signal (prole for use in solar thermal systems)

Description of Pump Frofiles
a) INTERNAL CONTROL - Proportional pressure
• Head (pressure): reduced with growing system
pressure drop and increased with sinking system
pressure drop (typically e.g. opening / closing of thermostatic heads)
• Pump operating point: moves up or down on the selected proportional pressure curve
depending on the current system pressure drop.
CONTROL MODE DESCRIPTION
Proportional pressure
I The lowest curve of proportional pressure
II The middle curve of proportional pressure
III The highest curve of proportional pressure
AUTOADAPT
Automatically controls performance in the range from the
highest to the lowest proportional pressure curve
b) INTERNAL CONTROL - Constant pressure
• Head (pressure): kept constant, disregarded
of the system pressure drop
• Pump operating point: moves on the selected constant pressure curve depending on the
current system pressure drop.
CONTROL MODE DESCRIPTION
Constant pressure
I The lowest curve of constant pressure
II The middle curve of constant pressure
III The highest curve of constant pressure
AUTOADAPT
Automatically controls performance in the range from the
highest to the lowest constant pressure curve
c) INTERNAL CONTROL - Constant speed
• The pump runs at constant speed.
• Pump operating point: moves up or down on the selected constant curve depending on the
current system pressure drop.
CONTROL MODE Max. H (upper graph) Max. P1(lower graph)
Constant speed
I 5 m 33 W
II 6 m 39 W
III 7 m 52 W
d) EXTERNAL CONTROL - PWM C (solar)
• The pump runs on a curve of constant speed depending on the current
PWM value.
• The speed will increase with the increase of the PWM value. If PWM equals 0, the pump
stops.

e) EXTERNAL CONTROL - PWM A (heating)
• The pump runs on a curve of constant speed
depending on the current PWM value.
• The speed slows down when the PWM value rises. If PWM equals 0, the pump runs at its
max. speed.

WARNING: LEDs may be turned by 90° or 180°, or mirrored, depending on the specific pump type.
When switched on, the pump runs at factory settings or the last setting. The display shows the current
pump performance.
Setting selection
To select your desired setting, press the button repeatedly until you find the setting you need (see the
table above). If you pass the desired setting, you have to go one more round until it appears again. The
order of modes corresponds to the table.
