6.1.4 Description of the electronic board (fig. 4)
6.2 Function of the product
ElectronicControl contains an electronic regulation system using pressure and
flow sensors and a frequency inverter.
The electronic regulation system allows to reach a constant pressure in the net-
work whatever the flow is and to minimize the power consumption of the
installation (automatic mode). The pressure will be constant according to the
set point pressure originally preset.
In hand mode the pump can be tested at maximum 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 pressure (P SET) and
when the flow is zero.
The ElectronicControl protects the pump against (Chap 10.2):
• dry running,
• over currents,
• too high water temperatures,
•frost,
• short-circuits,
• over voltages,
•Undervoltages.
In case of defect (such as dry running, overvoltage …), the led blinks and the
ElectronicControl will try to start the pump regularly. After many trials the Elec-
tronicControl finally stops, the led is ON and does not blink anymore.
6.3 ElectronicControl setting
After connection to the pump and to the power supply, the ElectronicControl
will show the model type and the software version for 10 seconds. Then the
ElectronicControl shows the STANDARD display mode.
Then the ElectronicControl has to be set in accordance to the pump character-
istics and to the requirement of the installation, in order to warranty a safe and
efficient operation.

DANGER! Risk of death!
An improper installation and electrical connections can result in a risk of fatal
injury.
• The installation and electrical connections should only be done by a qualified
electrician and in compliance with the regulations in force.
• Follow all accident prevention regulations!
• Before installation and electrical connection, switch off the product/station
shall (no voltage) and be sure it cannot be switched on again without any
control!
• Disconnect the mains plug!

7.1 Installation
• Install the ElectronicControl in a room with easy access, normal ventilation and
protection against frost and rain and very close to the pump.
• For any maintenance works enough space shall be provided around the instal-
lation. An easy access from at least both sides of the installation shall be
ensured.
CAUTION! Risk of malfunction!
The ElectronicControl axis shall be correctly positioned in a vertical line.
The ElectronicControl shall be connected to the pump discharge pipes next
after the check valve (Fig. 2). The piping diameter shall be the same or bigger
than the one of the ElectronicControl. A complete tightness of the installation
shall be ensured, in case of a leakage the system might run over a cycle and then
be damaged. The installation piping shall not apply any stress on the Electron-
icControl.
CAUTION! Risk of product and subsequent damages!
Do not put any foreign matters into the ElectronicControl when installating
it (glue, treacle, chips …),
The assembling of a check valve directly at the ElectronicControl suction (Fig. 2,
Pos. 3) is mandatory to ensure a right operating of the ElectronicControl. A blad-
der tank over 2 liter volume (Fig. 2, Pos. 4) shall allow an optimal regulation of
the pressure inside the installation. A pre-setting pressure 0.5 bars lower than
the set point pressure is recommended.
A filter or a suction strainer shall be assembled to avoid any pumping of particles
that might hinder the proper operating of the ElectronicControl.
7.2 Electrical connection
DANGER! Danger of electric shock!
The electrical connection shall only be carried out by an electrician approved
by the local electricity supply company and according to the local regulations
in force.
7.2.1 Electric connection of the ElectronicControl
The ElectronicControl shall be installed with cables provided by the manufac-
turer. If a cable is damaged, have it replaced by a qualified personnel.
The type of current and the network voltage shall comply with the characteris-
tics of the ElectronicControl. See identification plate of the ElectronicControl.
It is recommended to install a 30 mA differential circuit breaker and a 16 A mag-
neto-thermal protection.
DANGER! Danger of electric shock!
Do not forget the earth connection of the motor.
For the electric connection of the installation to the network the ElectronicCo-
ntrol plug shall be connected to the electric network.

Installation and operating instructions Wilo-ElectronicControl 26
English
7.2.2 Electric motor connection
The ElectronicControl shall be connected to the pump motor terminal according
to the wiring diagrams Fig 5 or Fig 6.
7.2.3 Electric connection of a dry running protection
The ElectronicControl can be provided with an additional dry running protection
such as dry contact (flow switch or others). See Fig. 7 for the connection.
8 Commissioning
CAUTION! Risk of health hazards!
Our ElectronicControl is tested in water. If any water remains inside it, for
hygiene reasons it is recommended to rinse it before any use in the potable
water network.
When switching on the ElectronicControl immediately carries out a diagnosis
that lasts 10 seconds and will display the type and version. The led is on.
In case of a pump at suction, the priming of the pump shall be done manually
(manual mode). During the priming step (see operating instruction of the pump)
it may drive the pump at its maximum speed.
As soon as the pump is priming on, the ElectronicControl can be switched on
Automatic mode.
9 Maintenance
Maintenance and repairs shall only be carried out by qualified personnel!
DANGER! Risk of death!
When working on electrical equipments, there is a risk of fatal injury due to
electrical shocks.
Before any maintenance or repair works, switch off the unit/station (no volt-
age) and be sure it cannot be switched on again without any control. Gener-
ally only a qualified electrician is authorized to repair damaged connection
cables.
Before a frost period it is necessary to drain the ElectronicControl.
Every 6 month check the right operating of the installation:
• the pressure of the bladder tank,
• the tightness of the connections and
• the proper closing of the valve.
