''DRY'' operation
Once the room temperature reaches the level that was
z
set, the outdoor unit repeats the cycle of turning on and
off automatically.
When the outdoor unit is turned off, the indoor unit fan
z
will stop, too.
(To prevent the humidity in the room from rising again)
When the room temperature is more likely to reach the
z
level that was set, the fan speed is set to ''breeze'' (light
wind) automatically.
''DRY'' operation is not possible if the outdoor tempera-
z
ture is 15 °C or less.
Should the power failure occurs while the
unit is running
When the unit automatically resumes operation after
temporary power failure, it uses the same settings before
the power was cut off.
