Points to take into consideration:
The reference pressure should be 10 meters above
the highest inlet in the system. It is advised to
adjust a reference pressure between 1.5 bars
and 2.5 bars.

4.3. Detecting failures

If the electronic circuit detects a lack of water, it will
stop the pump and the alarm led will flash. The
circuit will run 4 attempts. If it does not manage to
re-establish the pressure due to a lack of water, the
circuit will remain in a failed status until it is
restarted manually.
While the pump is stopped in a failed status and
waiting for a reattempt, the alarm led will flash. After
4 unsuccessful reattempts, the alarm led will remain
on.
The following graph shows the time that passes
between the various reattempts if none of them are
successful.
