fastened to avoid water entering into the control box and damaging the electronic
circuit.
STARTING
When the unit is connected to the electrical network, the green led “Power On” lights up and the
yellow led “On” (pump in operation) 2 seconds later indicating that the pump has been started.
reach the required pressure.
pressed and wait, with a tap opened, until the red led is off.
Once the button is released the tap is closed, the unit stops the pump at its maximum pressure.
FUNCTIONING
This unit is programmed to perform all the pump control operation automaticlly.
When breakdowns occur, such as water failure, obstruction of the suction pipe etc., the unit can
prevent damages caused by its working in the absence of water.
When there is no water supply to the system, the water pump will stop automatically after 20s
running and the red led will glint.The water pump runs automatically for 40s after stopping for 10s
and checks the water supply; If there is no water supply, the water pump runs automatically for
40s after stopping for 10s again and checks the water supply; If there is still no water supply, the
water pump will stop automatically and turn to the dry - running protection status.After 24 hours,
the pump will start automatically and repeat the above procedures. During stopping the pump, the
pressing the “Restart” button.

INSTRUCTIONS FOR CORRECT UNIT INSTALLATION
If the column of water
between the pump and the
highest tap exceeds 20m,
the unit cannot be installed
directly on the pump, but it
has to be raised until the
column of water between
the unit and the highest
tap does not exceed 20m.
i.e. If column of water is
25m from the pump, the
unit must be placed 5m
higher than the pump.
It is advisable to connect
the unit outlet to the
system by means of a
Safety valve preventing
water emission in case of
diaphram breaks
DO NOT TOUCH
It is imperative to install
the unit with the arrows in
the upwards position.
The unit can be installed
directly on the pump, or
between the pump and the
The unit is equipped with
a check valve to prevent
the pipeline from losing
pressure.
NO taps can be installed
between the pump and the
unit.
PUMP’S PRESSURE
The unit is pre-set by the
manufacturer at a restarting
pressure of 2.2 bar.
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.

Once the button is released the tap is closed, the unit stops the pump at its maximum pressure.
FUNCTIONING
This unit is programmed to perform all the pump control operation automatically.
If no water is supplied to the system, i.e no water in tank or closed supply/suction pipe, the system
will run the following sequence: Switch off after 20 seconds if no water is detected, stop for 10
seconds, run for 40 seconds stop for 10 seconds, run for 40 seconds stop for 10 seconds. The
controller at this point will go into run dry protection. The power light will stay illuminated and
the Failure light will flash slowly after this time. When the failure light is flashing, it means the
pump will restart after 24 hours in the sequence mentioned above. The system will repeat this
every 24 hours until water is detected.
The pump can be restarted at any time by pressing the reset button.
