1.1 Consignment of the machine
As soon as the machine is consigned, it is essential for
the user to make sure that he has received all the items
indicated on the consignment note and that the
machine has not been damaged during transport. If
damage is discovered, allow the forwarding agent to
ascertain its entity and also inform our seller. Only in
this way will you be able to receive the missing items or
reimbursement of damages within the shortest possible
time.
1.2 Foreword
This air conditioner has been designed and
manufactured for air conditioning requirements only and
must therefore be used for this purpose alone. Even
the best of machines are capable of operating efficiently
and correctly only if they are used in the correct manner
and kept fully efficient. You are therefore kindly
requested to carefully read this instruction manual and
to consult it each time difficulties should arise when
using the machine or when in doubt. In any event, we
remind you that if necessary, our assistance service,
organized in collaboration with our dealer, is always at
your disposal for any advice or direct intervention
required.
The following symbols are used inside the manual
in order to rapidly find the most important

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.
3.1.3 Basic management
3.1.3.1 Manual switching on /off of the
equipment
Keep the key pressed for 1 second: the
on/stand-by LED will switch off/on.
The equipment can be switched on/off also
in certain timeslots; the parameters HOn and
HOF if the temperature required is not more
than 56 °C (SP5 parameter).
Manual switching on/off always has the
priority over the timeslot operating mode.
If the keyboard has been locked or an
advanced procedure is in progress, it will
not be possible to carry out the normal
switching on/off of the equipment.
Every time the equipment is switched on,
a series of internal inspections are carried
out before the heat pump is enabled. Such
condition is reported by means of the
flashing of the compressor indicator light
. Once the verification period has
passed (approx. 5 minutes) the indicator
light remains lit and this indicates that the
unit is switched on.
3.1.3.2 Change of operating mode
(AUTOMATIC, ECONOMY and
OVERBOOST)
If you want to change the operating mode,
than the one set press for one second

desired one.
Press and release the button to confirm
your choice.
To exit the procedure:
Press the key to exit this procedure without
changing the mode.

ADVANCED MANAGEMENT
N.B.: The following instructions are
reserved for specialised
technical
assistance personnel.
3.1.3.12 Different operating mode start
conditions
Each operating mode must comply with precise
conditions in order to be enabled:

3.1.3.13 Alarms
Note: in case of “UtL” alarm (fault of the
fan), in addition to the display visualization,
the equipment emits an acoustic signal
that can be switched off pressing any key
on the controller. The alarm it is never
canceled unless the equipment is switched
off or put in stand
-by.
The heat pump working mode is
automatically disabled and the one with
electric resistance is activated in order to
ensure the continuity of the warm water
supply.
PLEASE NOTE!: in case of “UtL” alarm it
is necessary to contact the technical
assistance.
