5. Description of the operation modes
1
FAN ONLY OPERATION
In this mode, the air is circulated without being heated or cooled.
2
DRY OPERATION
In this mode, the air humidity will be lowered by intermittently
turning the air conditioner ON in cooling and OFF again to
minimise the temperature decrease.
The temperature and fan speed are controlled automatically
and cannot be controlled by the user interface.
Dry operation will not function if the room temperature is too
low.
3
AUTOMATIC OPERATION
In this mode, the user interface will automatically switch
between heating and cooling as required by the setpoint.
4
COOLING OPERATION
In this mode, cooling will be activated as required by the setpoint
or setback operation.
5
HEATING OPERATION
In this mode, heating will be activated as required by the
setpoint or setback operation.
6
SETBACK
The setback function will maintain the room temperature in a
specific range when the user interface is turned OFF. This is
done by temporarily starting the air conditioner that was
previously turned OFF by the user, the schedule function or the
OFF timer.
For example:
If the room temperature drops below 10°C, heating is started
automatically. If after half an hour the temperature increases
to 12°C or above, the user interface returns to its original
state.
If the room temperature goes above 35°C, cooling is started
automatically. If after half an hour the temperature decreases
to 33°C or below, the user interface returns to its original
state.
The differential can be adjusted in the setback menu. The
setback temperature can be set while the unit is turned OFF on
the basic screen, or can be set in the schedule.
The status of setback (enabled/disabled) can be seen in the
Energy Saving List.
By default, the setback function is disabled. Before enabling
it, first consult the detailed information about
SETBACK
in the
user reference guide.
