Energy saving and optimum
operation
Observe the following precautions to ensure the
system operates properly.
• Adjust the air outlet properly and avoid direct air
flow to room inhabitants.
• Adjust the room temperature properly for a
comfortable environment. Avoid excessive
heating or cooling.
• Prevent direct sunlight from entering a room
during cooling operation by using curtains or
blinds.
• Ventilate often.
Extended use requires special attention to
ventilation.
• Keep doors and windows closed. If the doors
and windows remain open, air will flow out of
your room causing a decrease in the cooling or
heating effect.
• Be careful not to cool or heat too much. To save
energy, keep the temperature setting at a
moderate level.
• Never place objects near the air inlet or the air
outlet of the unit.
It may cause deterioration in the effect or stop
the operation.
• Turn off the main power supply switch to the unit
when the unit is not used for longer periods of
time. If the switch is on, it consumes electricity.
Before restarting the unit, turn on the main
power supply switch 6 hours before operation to
ensure smooth running. (Refer to “Maintenance”
in the indoor unit manual.)
• When the display shows “
” (time to clean
the air filter), ask a qualified service person to
clean the filters. (Refer to “Maintenance” in the
indoor unit manual.)
• Keep the indoor unit and remote controller at
least 1 m away from televisions, radios, stereos,
and other similar equipment. Failing to do so
may cause static or distorted pictures.
• Do not place items under the indoor unit,
they may be damaged by water.
• Condensation may form if the humidity is above
80% or if the drain outlet gets blocked.
Your system is equipped with advanced energy
saving functionality. Depending on the priority
emphasises can be put on energy saving or
comfort level. Several parameters can be selected,
resulting in the optimal balance between energy
consumption and comfort for your particular
application.
Several patterns are available and roughly
explained below. Contact your installer or dealer
for advice or to modify the parameters to the
needs of your building.
Detailed information is given for the installer in the
installation manual. He can help you to realize the
best balance between energy consumption and
comfort.
