6.8 Electrical connections

Before connecting the appliance to AC mains, a check must be
carried out on the electrical system to verify conformity to the
regulations in force and that the electrical system can suitably
withstand the water heater's maximum power consumption val-
ues (refer paragraph 4.2 for technical characteristics), in terms
of the size of the cables and their conformity to the regulations
in force.
The appliance is supplied with a power cord with a Schuko plug
(fig. 25) and for the connection with AC mains is required:
• a Schuko wall socket with ground and separate protection is
required (fig. 24);
• an omnipolar 16 A circuit breaker with a contact opening of
at least 3 mm;
• a 30 mA differential circuit breaker.
It is forbidden to use multiple outlet sockets, extension cables
or adaptors.
It is forbidden to use piping from the water, heating and gas
systems for earthing the appliance.
Prior to operating the machine, make sure that the electricity
mains voltage conforms to the value indicated on the appli-
ance's data plate.
The manufacturer of the appliance shall not be held liable for
any damage caused by failure to earth the system or due to
anomalies in the electric power supply.

6.8.1 Remote connections

The equipment is designed to be connected to other remote
energy systems or energy meters (solar thermal, photovoltaic,
Off-Peak)
INPUTS
• Digital 1 (DIG1). Digital input for solar thermal (only for mod-
els LT-S). In case of a solar thermal system with dedicated
control unit, the latter can be connected to the equipment to
deactivate the heat pump when there is energy production
from solar source. Having a voltage-free contact that closes
when the solar system is active, it can be connected to the
two white and brown wires of the 6-core cable supplied with
the equipment.
Set the parameter P16 = 1 to activate the supplement with
solar thermal.
• Digital 2 (DIG2). Digital input for photovoltaic. In case of a
photovoltaic system connected to the plant, it can be used
to subtract energy in the form of hot water in times of over-
production. If there is a voltage-free contact, e.g. from the in-
verter, which closes when there is overproduction of energy,
it can be connected to the two green and yellow wires of the
6-core cable supplied with the.equipment.
Set the parameter P23 = 1 to activate the supplement with
photovoltaic.
• Digital 3 (DIG3). Input for Off-Peak. This function, available
only in some countries, allows the equipment to be activated
only when there is a signal coming from outside with prefer-
ential tariff. If the electric contactor has a voltage-free contact
which closes when the preferential tariff is available, it can be
connected to the two gray and pink wires of the 6-core cable
supplied with the equipment.
Set the parameter P24 = 1 to activate Off-peak in ECO mode
or P24 = 2 for Off-peak in AUTO mode.
• Digital input (LPSW) for the flow switch of the solar thermal/
DHW circulating pump (not supplied)
• Analog input (PT1000) for solar collector probe.
