8.1.2 Operating logic

8.1.2.1 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 SP5
parameter 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 lower than SP3 parameter.
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
60°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 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 guarantees the user
an average energy saving of approx. 70%
when compared to a normal electric boiler.
