3.1.2 Operating logic
3.1.2.1 Operating modes
The equipment foresees the following operating
modes:
AUTOMATIC operating mode
This mode mainly uses the renewable energy
of the heat pump as a support measure, the
electric heating elements can be enabled;
these latter heating sources are enabled if the
water temperature is below a certain level, or

Manuale utente
pag. 6 /
15
in the event that a temperature exceeding
56°C is required;
ECONOMY operating mode
This mode uses only the renewable energy of
the heat pump without ever enabling the
electric heating elements. It takes longer to
enable but it has considerable energy saving
characteristics;
OVERBOOST operating mode
This mode makes it possible to heat water
rapidly by using both the heat pump and the
electric heating elements. This function can be
manually enabled when the temperature of
the water inside the storage tank is below
40°C. At the end of the heating process, the
function is automatically disabled and the
equipment is automatically restored to the
Automatic or Economy mode depending on
which of these functions was previously set by
the user;
ANTI-LEGIONELLA operating mode
This function is used as an anti-bacterial
treatment by increasing the temperature of
the water to 70°C. This function is periodically
and, in any case, automatically enabled every
30days, regardless of the operating mode
enabled;
DEFROSTING mode
This function is necessary in order to eliminate
the frost deposits that form and which prevent
heat transmission. This function is automatically
enabled when the equipment is operated at
low environmental temperatures.
When the
equipment
is switched on for the
first time, it is pre
-
set by the manufacturer in
the ECO (Economy) mode
with a water set
point
of
55°C with the aim of guaranteeing
the best possible energy saving function
with the support of only renewable energy
sources. Please note that the use of such
function guarantee
s
the user an average
energy saving of approx. 70% when
compared to a normal electric boiler.

operations on parts that perform safety
functions jeopardises the safe
operation of the equipment. Substitute
the faulty elements only with original
spare parts.
N.B.: The intervention of the thermostat
excludes the operati
on of the electric
heating elements but not the heat
pump system within the permitted
operating limits.

4.2 Control le dispositif contre les surpressions
Il faut faire fonctionner régulièrement le dispositif
contre les surpressions au moins tous les 30 jours
pour éliminer les dépôts de calcaire et pour vérifier
qu’il n’est pas bloqué (Fig 6A).

NB: component supplied to the mod. 90
4.3 Quarterly inspections
Visual inspection of the general conditions of
the equipment systems as well as the absence
of leaks;
Inspection of the ventilation .
4.4 Annual inspections
Inspection of the tightness of bolts, nuts,
flanges and water supply connections that
may have been loosened by vibration;
Check the state of integrity of the magnesium
anodes .
4.5 Cleaning of the ventilation filter
For the mod. 160-200-260
In the upper part of the equipment there is a
ventilation filter. This must be periodically cleaned
in order to maintain the perfect efficiency of the
system.
After every 1000 hours of operation, the display of
the equipment shows the “FiL” alarm that indicates
the need to check the cleanliness of the filter.
To remove the filter, it is necessary to grab it with
the fingers from the dedicated side opening and
pull it outside (Fig. 7).
The filter can be cleaned with rinsing, water gush
or slamming. Since the filter is made of stainless
steel, it does not need to be periodically
substituted.
Fig. 7–Details of the ventilation filter
N.B.: The filter obstruction
reduces the
heat pump system performance
causing insufficient,
or, even total lack
of ventilation.

4.6 Magnesium anodes
The magnesium anode (Mg), also called
"sacrificial" anode, avoids any parasitic currents
that are generated inside the boiler that can
trigger corrosion processes on the device surface.
In fact, magnesium is a metal with a lower
electrochemical potential when compared to the
material that lines the inside of the boiler, therefore
it first attracts the negative charges that form with
the heating of the water and that cause it to
corrode. Therefore, the anode “sacrifices” itself by
corroding instead of the tank. The boiler has two
anodes, one that has been mounted in the lower
part and another in the upper part of the tank (the
area that is most subject to corrosion).
The integrity of the magnesium anodes must be
checked at least every two years (even better if
checked on an annual basis). The operation must
be carried out by qualified personnel.
Before performing the inspection, it is necessary to:
Close the cold water input supply;
Empty the water from the boiler (see
paragraph 8.5);
Unscrew the upper anode and check its state
of corrosion, if more than 30% of the anode
surface is corroded then it is necessary to
replace it;
Carry out the same operation for the lower
anode.
The anodes have appropriate sealing gaskets, in
order to avoid causing water leaks, it is
recommended to use anaerobic sealant for
threads compatible for use on sanitary and
heating systems. The gaskets must be substituted
both in case of inspection as well as the
replacement of anodes with new gaskets.
For the mod. 90
To carry out the verification of the replaceable
anode it is necessary to drain the water from inside
the boiler (see paragraph 4.6).
For the verification or substitution of the sacrificial
anode, remove the lower panel (Fig. 5)
After having removed the lower panel, disconnect
the four electrical connectors of the electronic
control unit. Once removed the panel, unscrew
counterclockwise the anode using an appropriate
instrument and remove the old sealing gasket (Fig.
8).
Verify the integrity level of the component. In case
there are evident, considerable corrosion marks
that could jeopardize its use (reduction of the
diameter, cavity, reduction of the length) carry out
the replacement of the anode taking care of
replacing the sealing gasket as well, both in case
of verification and replacement (Fig. 8).
At the end of the verification or the replacement
of the anode, it is recommended to reset the
water connection (previously removed to allow
the emptying of the boiler) filling and pressurizing
the boiler in order to verify that no water losses are
incurred in the area where the maintenance
intervention has been carried out.
At the end of the verifications, reassemble the
product following backwards the indications
reported in this paragraph.
The operation of periodical verification or
replacement of the magnesium anode is
an opportunity to carry on other little
maintenance operations in order to
ensure
the maximum efficiency of the
product.
In particular, once removed the aesthetic
components the evaporator can be
accurately cleaned, using a brush with
soft bristles
,
taking care not to deform the
aluminum fins. It is also possible to verify
that there are no dirt deposits in the
condensate drain
pipe.
These little precautions ensure the total
efficiency of the product with a
consequent energy saving.

4.7 Emptying the boiler
It is advisable to drain the water from inside the
boiler if the boiler is idle for a certain period of time,
especially in low temperatures.
As for the equipment in question, it is sufficient to
disconnect the water supply input connection).
Alternatively, during the system installation stage, it
is advisable to install a drain tapwith a hose-
holding connection.
N.B.: It is important to empty the system
in case of low temperatures
in order to
avoid the water freezing.
