SETTING MODE
A) Setting display
switch from performance display to setting display,
press button (1). The LEDs shows the current setting. See
the following table for the meaning of the LED display.
Setting display mode shows the type of pump control or
the currently selected pump curve. Settings cannot be
changed in performance display mode. After 2 seconds,
the display returns to performance display mode.
If LED 1 is red, it indicates that an alarm is active or that
the the pump is being controlled by an external (PWM)
signal.
LEDs 2 and 3 show the type of internal control while LEDs
4 and 5 show the currently selected curve (1, 2, 3 or 4).
All these LEDs are yellow in colour.

B) Button lock function
The button lock function serves to prevent improper use
or accidental changes to pump settings.
When the button lock is active, pressing the button has
no effect. This prevents users from accidentally acces-
sing setting mode while allowing them to use setting
display mode.
Press and hold the button for more than 10 seconds, to
activate / deactivate the button lock.
When the button is held down for 10 seconds, all the
LEDs except the red LED flash for one second to indicate
that the button lock function has been activated/deac-
tivated.

C) Setting mode
To access setting mode, press and hold the button (1)
for between 2 and 10 seconds. The button lock must be
deactivated in order to change settings. Available set-
tings are displayed in a pre-defined sequence that is
repeated every time the button is briefly pressed and
released. If the button is not pressed for over 10 secon-
ds, the pump exits setting mode and returns to perfor-
mance display mode. The last settings made are saved
in memory. See the table above for the meanings of the
LED sequences.
