6.2.7 Lack of water protection
The booster needs to be fitted with a dry-run-
ning protection device:
• Connection to public water supply: pressure
switch to be assembled on the suction manifold
and connected to the ElectronicControl.
• Connection to a tank: float switch to be installed
on the tank and connected to the
ElectronicControl.
6.3 Product function
6.3.1 Operating
The automatism of system is ensure by
ElectronicControl. 1 pump is set to Master for
the other.
ElectronicControl contains an electronic regula-
tion system using pressure and flow sensors and
a frequency inverter.
The electronic regulation system allows to reach
a constant pressure in the network whatever the
flow is and to minimize the power consumption
of the installation (automatic mode). The pres-
sure will be constant according to the set point
pressure originally preset.
In hand mode the pump can be tested at maxi-
mum speed.
In automatic mode the ElectronicControl starts
the pump when the installation pressure (NET P)
is lower than the set point pressure (P SET)
minus the pressure gap set (START DELTA P).
The ElectronicControl stops after a time period
set (TIME BEFORE STOP) when the installation
pressure (NET P) has reached the set point pres-
sure (P SET) and when the flow is zero.

The ElectronicControl protects the pump against
(§ 10.2):
- dry running,
- over currents,
- too high water temperatures,
- frost,
- short-circuits,
- over voltages,
- Under voltages.
In case of defect (such as dry running, overvolta-
ge ...), the led
blinks and the
ElectronicControl will try to start the pump regu-
larly. After many trials the ElectronicControl
finally stops and the led
blink anymore.
6.3.2 ElectronicControl setting
After connection to the pump and to the power
supply, the ElectronicControl will show the
model type and the version for 10 seconds. Then
it shows the STANDARD display mode.
Then the ElectronicControl has to be set in
accordance to the pump characteristics and to
the requirement of the installation, in order to
warranty a safe and efficient operation.
Press the push-button
the ElectronicControl. The user can navigate in
both menu levels, SETTINGS or HISTORIC:
• SETTINGS: this level allows the setting of the
ElectronicControl according to the installation
and the pump.
• HISTORIC: this level displays the various counts
and alarms recorded.
To select a menu level, use the the
push-buttons
or
select it.
The values displayed in the various menus can be
changed via the push-buttons
the push-button
validated and the next menu is displayed on the
screen. With the push-button
TINGS (no saving of the last change) or HISTORIC
menu and go back to STANDARD display mode
(or SERVICE).
NOTA: the data are saved in non-volatile memo-
ry, this allows to save data even after switching
