Advice for saving Energy

8.1 Suitable room Temperature
Set the room temperature to an appropriate value to
guarantee physical wellbeing, comfort and, in any case,
to comply with the legal standard. Each degree above
this value significantly increases the energy
consumption.
The temperature must also be suitable for the specific
use being made of the room: the temperature of empty
rooms and bedrooms does not have to be the same as
the main room.
8.2

Eliminating Heat or Cold Sources

In the event that there are any heat (in cooling mode) or
cold (in heating mode) sources that could be eliminated
please do so (e.g. a window or a door which are not
properly closed). This will ensure that the unit consumes
less energy.
8.3

Operation in Heating Mode (Heat Pump)

Your unit, when operating in heating mode, acts as a
heat pump, i.e. it takes heat from the outside (via the
outdoor unit) and releases it inside (via the indoor unit).
Nevertheless, a conventional heating system produces
heat purely by consuming energy. Therefore, heating a
room using a heat pump is far more economical than
using conventional heating (radiators, heaters, boilers,
etc.).
8.4

Ambient Temperature when absent

During heating mode, an economic saving is made by
keeping the room temperature at approx. 5ºC lower than
the normal temperature. A reduction which exceeds
these 5º C does not provide any further energy savings
since greater heating power is required for consecutive
periods of operation in normal operating conditions.
It is only worth reducing the temperature even further in
the event of prolonged absences, e.g. during holidays.
During winter when protection against freezing must be
guaranteed.

8.5

Uniform Heating

Often in a house only the one room is heated. In addition
to the surfaces which form the perimeter of this area,
i.e. the walls, doors, windows, ceiling and floor, the
adjacent rooms are cooler than the room temperature
therefore: thermal energy is unintentionally lost. It is
therefore difficult to adequately heat the room and an
unpleasant feeling of cold is felt (the same occurs when
leaving open doors which separate heated areas and
unheated areas in a limited way).
This is false economy: the heating is on and,
nevertheless, the ambient temperature is not pleasant.
Greater comfort and a more reasonable operating mode
are achieved by heating all the rooms in a house
uniformly, taking into account the use being made of
each room (the temperature of empty rooms and
bedrooms does not have to be the same as the main
room, as long as they are not significantly cooler than
the main room).
8.6

Reduction in Consumption during Night Hours

(SLEEP Function)

Your unit has a SLEEP function which allows the
temperature to be modified automatically in relation to
the predetermined values (in heating mode the
temperature decreases slightly; in cooling mode the
temperature increases slightly) during sleep setting
period. Thus, apart from greater comfort being provided
there is also a reduction in the electricity consumption.
For more details regarding the SLEEP function, please
consult section 7.7.1).
8.7 Reduction in Consumption with programmed
Operating Time (TIMER Function)
By using the TIMER function you can adjust the
operation start time of your unit. Therefore, it is possible
to programme the operation of your unit to make it
function only when required and thus achieve more
economic operation.
8.8

Appropriate Maintenance of the Unit

A unit in perfect condition operates efficiently, taking
maximum advantage of the energy it consumes. Ensure
that your unit is correctly serviced (for more details
please consult section 10). In particular, make sure that
the filters are kept clean and that the air inlets and
outlets are not obstructed either on the indoor or
outdoor unit. Failure to do so will lead to an increase in
energy consumption.
