6.3 Aeraulic connections
In addition to the spaces indicated in 6.1, the heat pump.re-
quires adequate air ventilation.
Create a dedicated air channel as indicated in fig. 12.
WARNING! The depression of the room due
to the expulsion of air to the outside, involves
air aspirations from the frames (doors and
windows). Prepare an air inlet (Ø 160mm) from
the outside to avoid sucking in the air from the
heated volume. In winter, the air that enters from
the air intake can cool the room.

It is also important to ensure adequate ventilation of the room
containing the unit. An alternative solution is shown in the figure
below (fig. 13): it provides for a second ducting that takes air
from the outside instead of directly from the inside room.

Install each air channel, making sure:
• It does not weigh down on the equipment.
• It allows maintenance operations.
• It is adequately protected to prevent the accidental intrusion
of materials inside the equipment.
• The connection to the outside must be done with suitable,
non-flammable piping.
• The total equivalent length of the extraction pipes plus the
delivery, including grilles, must not exceed 12 m.

During operation, the heat pump tends to lower the room tem-
perature if the air ducting is not to the outside.
A suitable protection grille must be installed at the air extrac-
tion pipe to the outside to prevent any foreign bodies from
entering inside the equipment. To ensure maximum product
performance, the grille must be selected from those with low
pressure loss.
To avoid the formation of condensation water: insulate the air
extraction pipes and the ducted air cover connections with a
steam-tight thermal covering of adequate thickness.
Install silencers if deemed necessary to prevent noise due to
the flow. Equip the pipes, wall outlets and connections to the
heat pump with vibration-damping systems.
WARNING! The depression of the room due
to the expulsion of air to the outside, involves
air aspirations from the frames (doors and
windows). Prepare an air inlet (Ø 160mm) from
the outside to avoid sucking in the air from the
heated volume. In winter, the air that enters from
the air intake can cool the room.
6.3.1 Special installation
One of the peculiarities of the heat pump heating systems is
that these units considerably lower the air temperature, gener-
ally expelled to the outside of the house. As well as being colder
than the ambient air, the expelled air is also completely dehu-
midified, therefore the air flow can be returned inside for the
summer cooling of specific rooms or areas.
Installation provides for splitting of the extraction pipe, which is
fitted with two dampers ("A" and "B") for directing the air flow to
the outside (fig. 15) or the inside of the house (fig. 14).

6.6.1 Condensate drain connection
The condensate forming during heat pump operation flows
through a special drain pipe (1/2"G) that passes inside the insu-
lating casing and comes out at the side of the equipment.
It must be connected, via a trap, to a duct so that the conden-
sate can flow regularly (fig. 20).

200 LT-S and 260 LT-S models)
The following figure (fig. 21) shows how to connect the equip-
ment to a solar thermal system controlled by a dedicated elec-
tronic controller (not supplied) that has a "voltage-free contact"
type output to be connected to the DIG.1 input of the equipment
(see “6.8.1 Remote connections”).
To use the equipment in this configuration it is necessary to set
the parameter P16 = 1 (see par. 8.1).

The following figures (fig. 22 and fig. 23) show how to connect
the equipment to a solar thermal system controlled directly by
the latter, without the aid of a dedicated electronic controller.
In the configuration of fig. 22, in case of solar collector overtem-
perature a drain valve (not supplied) is activated to discharge in
a DHW storage tank (puffer) hot water contained in the equip-
ment.
In the configuration of fig. 23, however, in this condition the solar
collector shutter is closed.
In both cases this occurs in order to allow the collector to cool
down.
To use the equipment in both these configurations it is neces-
sary to set the parameter P12 = 2 and P16 = 2 (see par.8.1).

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.
