7.1.2 Operating logic
7.1.2.1 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 in the event that a temperature
exceeding
62°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
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

If this is lit: the equipment is
in the stand-by status.
If it is flashing, the equipment
has been switched on/off
manually during a switching
on/off period in a certain
timeslot.

When the equipment is switched on for the
first time, it is pre-set by the manufacturer in
for
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
guarantees the user an average energy
saving of approx. 70% when compared to a
normal electric boiler.
7.1.3 Basic management
7.1.3.1 Manual switching on /off of the equipment
•
Keep 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 can
be seen (paragraph 7.1.3.4).
Manual switching on/off always has the
priority over the timeslot operating mode.
If the keyboard has been locked (paragraph
7.1.3.3) 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
verification period has passed (approx. 5
minutes) the indicator light remains lit and this
indicates that the unit is switched on.
