Read carefully before proceeding with product assembly and commis-
sioning operations. For the pump, refer to its manual.
1. APPLICATIONS AND OPERATION
The GENYO electronic controller commands the starting and stopping of
single-phase electric water pumps whenever a tap or valve connected to
the installation is opened or closed, respectively.
When the pump is started, it keeps running as long as any connected tap
remains open, supplying the network with the required flow at the related
pressure.

4. HANDLING AND PRELIMINARY INSPECTION
Handle with care.Falls and collisions can damage the product.
Before proceeding with installation, make sure GENYO shows no visible
signs of damage, otherwise contact the reseller.
5. INSTALLATION
GENYO must be assembled and installed by personnel qualified in accor-
dance with the regulations locally in force.
5.1 Water Connection (Fig.1)
GENYO must always be installed in the vertical position, with the
arrows pointing upward, connecting the R1 threaded inlet to the
pump's outlet and the R1 threaded outlet to the network.
Use flexible pipes for connection to the water network, protecting the
appliance from any bending loads and vibrations, a ball tap to isolate the
pumpset from the network, a tap (A) on the same level as GENYO and a
foot valve (Fig.1).
Before starting up the unit, fill the suction circuit with water
!
as specified in the pump's manual.
WARNING.
The maximum operating height between the pump and
the highest point in the system will depend on the start pressure. The
maximum pressure of the pump (closing contact pressure) must
exceed a value that depends on the start pressure. Both these limits
are specified in the table below.

5.2 Electrical Connection (Fig.2)
The connections must be made by qualified personnel. Install
a high-sensitivity differential switch (0.03 A) for protection
against lethal electric shock.
First of all, connect the ground conductor.
Make sure that the mains voltage corresponds to the rated volta-
ge. Remove the cover 1 from the electronic board and make the electri-
cal connection according to the instructions shown on the plate 2.
GENYO can also be used with a single-phase pump with electrical input
greater than 16 A, or a three-phase pump, using an auxiliary remote con-
trol switch (230 V coil) or control panel. In this case the electrical con-
nections must be made as shown in the diagram, Fig.3 and the resistance
must be cut as shown in Fig.5.
WARNING.
Power supply voltages other than those specified or
improper connections can damage the electronic circuit irreparably.
H07RN - F 3G1,5 type cables (Ø 9 ÷ 12 mm) must be used in
!
order to ensure IP 65 protection.

6. START UP
1) Check that the pump is primed properly, then partially open a tap in the
user circuit.
2) Connect GENYO to the power mains; the power LED will light up (POWER).
3) The pump will start up automatically and within 20 to 25 seconds the
system should reach approximately the maximum pressure delivered by
the pump. While the pump is running, the corresponding LED (ON) will
remain illuminated.
4) Close the tap mentioned under point 1). After 10-12 seconds the pump
will stop running, but the power supply LED (POWER) will remain lit. Any
malfunctions occurring after these operations will be caused by improper
priming or failure to prime.
7. STARTING PRESSURE ADJUSTMENT (P. Start)
GENYO is factory set to start with a minimum pressure of 1.5 bar. This
pressure can be increased up to 2.5 bar by rotating the screw found at
the top of the device, which can be seen by detaching the middle part of
the warning label (see Fig. 4).
For this purpose:
1) Read the pressure indicated by the gauge when the pump is started.
2) Disconnect the power supply.
3) Open a tap to discharge the pressure.
4) Adjust the screw at the top to increase (or decrease) the start pressure.
5) Supply power to GENYO; if you are not satisfied with the adjustment,
repeat the operations described above until you obtain the desired
pressure value.
N.B. The maximum pressure of the pump (closing contact pressure)
and the minimum start pressure must comply with the values shown
in the table under paragraph 5.1 otherwise GENYO will go into FAI-
LURE mode.
8. AUTOMATIC RESET FUNCTION
If the device goes into failure mode, this function will execute a series of
automatic starts to attempt to restore operation without any manual inter-
vention via the RESET button.
The system operates as follows: The appliance is in failure mode due to
water failure, for example; after 5 minutes in this condition the system will
do a 25-second RESET, attempting to prime the pump. If the system is
able to prime the pump, the failure will disappear and the pump will be
ready to operate without any problems. However, if the failure persists, the
system will do another RESET after 30 minutes, and will continue in this
manner systematically every 30 minutes for 24 hours. If the failure still per-
sists after all these attempts, the system will remain in this condition until
the problem has been resolved by manual intervention.
9. TROUBLESHOOTING
1.- THE PUMP DOES NOT STOP:
A) Water loss exceeding 3 l/min. Make sure that all the taps along the
pipeline are closed.
B) Electronic board malfunction: replace the electronic board.
C) The electrical connection is incorrect: refer to the instructions in Fig.2.
2.- THE PUMP DOES NOT START:
A) The pump is not primed; the protection against dry running has step-
ped in and the FAILURE LED is on: prime the water pipe, drain the
system water by opening tap (A) on the same level as GENYO to
decrease the pressure of the water column over it (Fig.1), and check
by pressing the manual start button (RESET).
B) The pump has shut down: the safety system has stepped in and the
FAILURE LED is on. If you press the manual start button (RESET) the
LED (ON) lights up; if the pump does not start call customer service.
C) Electronic board malfunction: disconnect the pump from the electrical
mains and re-connect it; the pump should start, if it does not replace
the electronic board.
D) No power supply: check the electrical connections, the POWER LED
must be illuminated.
E) The pump delivers insufficient pressure, the safety system has step-
ped in and the corresponding LED (FAILURE) is illuminated: make
sure that the pump pressure corresponds to the pressure value speci-
fied in the relevant table in the section titled "Water Connection".
F) Air is entering the pump through the suction side: the pressure is much
below normal, with constant fluctuations. The safety system will step in
and stop the pump, the FAILURE LED will light up. Check the seal and
connections in the suction pipe.
3.- THE PUMP KEEPS STARTING AND STOPPING:
There is a small leak in the delivery pipeline: check for any dripping taps
or running toilets.
