When to use which feature
You can use the following table to determine which features to use:
Feature
Tasks
Basic features
Operation
modes and
temperature
To start/stop the system and to set the
temperature:
•
In Heating and Cooling mode, heat up
or cool down a room.
•
In Fan only mode, blow air in a room
without heating or cooling.
•
In Drying mode, decrease the
humidity in a room.
•
In Automatic mode, an appropriate
temperature and operation mode is
automatically selected.
+
Airflow
direction
To adjust the airflow direction (swing or
fixed position).
Airflow rate
To adjust the amount of air blown into the
room.
To run more quietly.
Advanced features
Streamer
To remove airborne allergens such as
mold, pollen, adjuvant substances,
viruses, bacteria...
Econo
To use the system when you are
also using other power-consuming
appliances.
To save energy.
Outdoor unit quiet
To decrease the noise level of the
outdoor unit. Example: At night.
Comfort
To automatically adjust the airflow
direction to cool down or heat up the
room more effectively.
Intelligent eye
To prevent the air from coming in direct
contact with people.
To save energy when nobody is in the
room.
Powerful
To cool down or heat up the room quickly.
Feature
Tasks
ON timer +
OFF
timer
To automatically turn ON or OFF the
system.
Weekly timer
To automatically turn ON or OFF the
system on a weekly basis.
Additional features
Wireless LAN connection To operate the unit using smart
appliances.
4-3 Operation mode and temperature setpoint
When.
Adjust the system operation mode, and set the temperature
when you want to:
•
Heat up or cool down a room
•
Blow air in a room without heating or cooling
•
Decrease the humidity in a room
What.
The system operates differently depending on the user
selection.
Setting
Description
Automatic
The system cools down or heats up
a room to the temperature setpoint. It
automatically switches between cooling
and heating if necessary.
Drying
The system decreases the humidity in a
room without changing the temperature.
Heating
The system heats up a room to the
temperature setpoint.
Cooling
The system cools down a room to the
temperature setpoint.
Fan
The system only controls the airflow
(airflow rate and airflow direction).
The system does NOT control the
temperature.
Additional info:
•
Outside temperature.
The system's cooling or heating effect
decreases when the outside temperature is too high or too low.
•
Defrost operation.
During heating operation, frost might
occur on the outdoor unit and decrease the heating capacity.
In that case, the system automatically switches to defrosting
operation to remove the frost. During defrosting operation,
hot air is NOT blown from the indoor unit.
•
Humidity sensor.
Control the humidity by decreasing the
humidity during cooling process.
