2.3
Function
The Hydrocontrol is an electronic pressure switch
with integrated dry running protection and back-
flow stopper. It serves to convert a surface pump
into a domestic water pump.
2.4
Functions of the pressure switch
Automatic operation of the pump
When a shut-off device in the pressure line is
opened, the pump is automatically switched on
by the pressure switch. When the shut-off device
is closed, the pressure switch switches off the
pump again once the maximum pump pressure is
reached.
Protection of the pump against dry running
The pressure switch is equipped with a safety de-
vice that switches off the pump in the event of a
lack of water.
The pump is switched off after approx. 45 s, sig-
nalled by the lighting up of the "Failure" LED.
Constant delivery rate and pressure
The pressure switch ensures a constant delivery
rate with constant pressure.
Functioning range of the pressure switch
ON pressure: approx. 1.8 bar
OFF pressure max.: 8.0 bar (or maximum pres-
sure of pump)
