"ACTIVE"
When the pressure in the unit falls below the threshold set on the pressure switches, the pressure switch(es)
becomes active. The LED flashes green (for pressure switch 1) or yellow (for pressure switch 2).
After the elapsed follow-up time (menu 1.2.5.1), the LED remains turned on permanently.
If key switch 1 or 2 is in the "Auto" position, the pump starts automatically.
When the pressure rises and exceeds the threshold set, the pressure switch passes to the passive state. It is
possible to turn off the LED by pressing the acknowledgement button (Fig. 2, pos. 11).
The acknowledgement is only accessible if the user has previously connected to level 2.
