8 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. Doing so may
cause a reduced heating/cooling effect or stop 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 compressor unit, heat exchanger unit, indoor unit and user interface 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, as they may be damaged by water.
▪
Condensation may form if the humidity is above 80% or if the drain outlet gets
blocked.
This heat pump 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 the 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.

The refrigerant temperature is fixed independent from the situation. It
corresponds to the standard operation which is known and can be expected from/
under previous VRV systems.
