The pump stops (U2 indicator ON) when the water level reaches
E1 and starts (U2 indicator OFF) when the water level drops
below E2.
If the water level drops below E4 for any reason, the pump stops
(U1 indicator OFF) and the alarm sounds.
Insert a pushbutton switch (NO contact) between E3 and E4.
When starting the pump or 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 releasing the pushbutton switch, keep
pressing the pushbutton switch.
