The pump stops when the water level reaches E1 and starts
when the water level drops below E2.
If the water level drops below E4 for any reason, the pump stops
and the alarm sounds.
Insert a pushbutton switch (NO contact) between 11 and 15.
When starting the pump and after recovering from a power
failure, if the water level has not yet reached E4, press the
pushbutton switch to start the pump by short-circuiting E3 and
E4.
If the pump stops upon release of the pushbutton switch, keep
pressing the pushbutton switch.
