Advice for saving energy

8.1

Suitable room temperature

Set the room temperature to an appropriate value to
ensure physical wellbeing, comfort and to comply with the
legal standards if required. 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
living 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.
