STARTING
When the unit is connected to
the electrical network, the green
led lights up and the yellow led
indicates that the pump has been
started.
The pump continues to operate for
dozens of seconds enabling the
system to fill in the pipes and to
reach the required pressure.
If this lapse is insufficient, the red
led lights up. In this event, keep the
reset button pressed and wait, with
a tap opened, until the red led is off.
Once released the button and
closed the tap, the unit stops the
pump at its maximum pressure.
FUNCTIONING
The starting operation archived,
the unit is programmed to perform
all the pump control operations
automatically.
When particular operational
breakdowns occur, such as water
failure, obstruction of the suction
pipe etc, the unit recognizes the
breakdown and the red led lights up.
At the same time a stop signal
is sent to the pump to prevent
damages caused by its working in
the absence of water.
Rectification of the failures that have
caused the blockage, allows the
system to be restarted by pressing
the restart button.
PUMPS PRESSURE
The unit is pre-set by the
manufacturer at a restarting
pressure of 1.5 bar.
By turning the screw (Fig. 6) you
can adjust the boot pressure.
Fig. 6
The pressure produced by the pump
must be normally 0.8 bar higher
than the pre-set pressure.
Before starting the unit, check
suction and ensure that the pump
is primed.
It is advisable to connect the unit
outlet to the system by means of a
flexible hose.
It is imperative to install the unit
with the arrows in upward position.
The unit can be installed directly on
the pump, or between the pump and
the first tap.
AUTOMATIC RESET
FUNCTION
If the pressure switch goes into
alarm, the automatic reset function
will perform a series of automatic
initiations to try to restore the
operation without any manual
interference in the “RESET” button.
If the pressure switch goes into
alarm mode, due to water failure for
example, the alarm led flashes.
The controller restarts the pump,
once every 15 minutes with the
source requirements, and tests
whether the water flow rate has
been reset.
If the water flow is restored, it will
exit the alarm mode otherwise the
alarm will be maintained and will
restart again.
