8.3.2 Self-learning function
The factory setting for this function is "on".
On
If the pump cannot reach the user-defined pressure setpoint, the
self-learning function will automatically adjust the setpoint.
The pump will lower the setpoint to either 4.5, 3.5 or 2.5 bar (65,
51 or 36 psi).
The self-learned setpoint is indicated on the operating panel by
one flashing green light.
After every 24 hours, the pump will automatically attempt to revert
to the original user-defined setpoint. If this is not possible, the
pump will again return to the self-learned setpoint. The pump will
continue to operate with the self-learning setpoint, until the
user-defined setpoint can be reached.
Example:
The user-defined pressure is set to 5 bar (72 psi), indicated by
constant green lights on the pressure indicator panel.
The pump is unable to reach this pressure due to negative
pressure on the inlet side.
The self-learning function automatically adjusts the setpoint to 3.5
bar (51 psi), indicated by one flashing green light on the pressure
indicator panel.
After 24 hours, the pump will automatically try to adjust the
setpoint back to 5 bar (72 psi).

How to reset the self-learned setpoint
1. You can manually reset the settings by pressing any button on
the operating panel. The pump will immediately try to reach
the original setpoint.
2. If the pump keeps reducing the setpoint due to self-learning,
we recommend to reduce the setpoint manually on the
operating panel.
Off
If you set the self-learning function to off and the pump is unable
to reach the desired setpoint, the pump will show alarm 5.
