Activating both up/down air swing and left/right air swing at the same time results in a multi-directional air flow.
However, if the fan speed setting is HI and room temperature is 19
or higher, this control is not executed.

When both the indoor and the outdoor air temperatures are in the range “A”, cooling or heating is switched depending on
the difference between the setting temperature and the indoor air temperature.
When the operation mode has been judged following the change of setting temperature with the remote control, the hourly
judgment of operation mode is cancelled.

(14) Outline of dry(dehumidifying) operation
The purpose is "Dehumidification", and not to control the humidity to the target condition.
Indoor/outdoor unit control the operation condition to reduce the humidity, and also prevent over cooling.
(i)
Indoor unit fan speed and compressor are controlled by the area which is selected by the temperature difference.

Set temperature
Difference between set temperature and return temperature
When the outside temperature and room temperature is low for cooling operation, indoor unit can not operate in cooling, and
dehumidifying. In this case, the units operate in heating to rise the room temperature and after that start dehumidifying operation.

(ii)
The indoor unit check the current area by every 5 minutes, and operate by the next checking.
