The “Automatic” speed mode for
each operation mode is used
independent of the setting.
(“LO” at the time of “Sensor

mode.
• The set temperature is set with
the room temperature adjustment
button. Correction by V, ±3°C is
possible with. At this time, the
operation mode judgement
temperature also is shifted at the
same time. However, correction
is possible only in cooling
operation mode, but not in
“Sensor dehumidification” mode.
