3.5 Electrical connections
3.5.1 Electrical recommendations
Only qualified professionals may carry out electrical connections, always with the power off. Separate the
very low voltage cables from the 230V circuit cables. The electrical power supply is done by means of a
mains connection cable (~230 V, 50 Hz) in accordance with prevailing national regulations for electrical
installations. Respect the polarities when making the electrical connections to the mains:
Brown wire (L) : Live
Blue wire (N) : Neutral
Green/yellow wire : Earth
If the power supply cable is damaged, you must have it replaced by a qualified installer.
The 2.5 mm2 section power supply cable for the electrical connection of the domestic hot water tank
must be used by the installer.
3.5.2 Electrical recommendations
Connect the power supply; the indicator will light up this time.
The thermostat will automatically control the temperature. When the water temperature inside the heater
has reached the set temperature, it will switch off automatically, when the water temperature falls below
the set point the heater will be turned on automatically to restore the heating.
