When selecting Soft Dry mode operation, the operation will be cooling until the room temperature reaches the set temp on
remote control, and then Soft Dry will be activated.(During Soft Dry Mode the fan of indoor unitwill operate at super low
speed.The soft dry mode will run for less than 10 minutes.)
Once Soft Dry mode operation is turned off, indoor fan, compressor and outdoor fan will stop for 6minutes.

Indoor fan operates at super low speed for 25 seconds.
After judging indoor air temperature, the operation is determined and operation continued at the mode determined.
After the operation mode has been determined, the mode does not change.However, Soft Dry mode operation
includes cooling mode operation.
If automatic mode operation is started while the unitis operating, operation will continue.
If current operation isin cooling mode (including the cooling mode operation when is a part of Soft Dry mode
operation) itwill be maintained, and if current operation is not cooling mode, the appropriate operation mode is
determined for 25seconds at super slow fan speed.Then the selected mode will continue.

Theairconditioner will compare themaximum valueof thecurrent measuring period (MAX) with the

Basic Operation
Detecting and indicating of the airquality will not stop during the operation of the air conditioner.
The power of the airquality sensor isalways on during the operation of the air conditioner.When the air
conditioner stops (The air conditioner is on standby.), the air conditioner will provide power to the airquality
sensor intermittently(Itwill be on for 3minutes after each 109 minutes.) for the purpose of airquality detecting.
Within2minutes after the air conditioner starts to operate, the airquality sensor isin the process of preheating
and the airquality indicator is red.
Resistance Reference
Detecting of airquality( During theoperationof theairconditioner)
(a) Themeasuring period is 20minutes; Theairconditioner will measure the resistance(Rs) oftheairquality
sensor onceeach 2 seconds and record thedata. Themaximum Rs within the20minutes will beselected as
Rs(MAX) for this measuring period.
(b) Supposethecurrent Rs(MAX) as MAX andtheresistancereferenceoftheprevious measuring period is as
MAXR1.; If MAX>MAXR1, the resistance referenceofthecurrent measuring period is MAXR=MAX; If
MAX<MAXR1, MAXR=MAXR1;
(c) Within 2 minutes after thepower of theairquality sensor is turned on, the resistance referenceof this
measuring period is themaximum resistanceofthesensor during this period.

for measuring theresistance. Theairconditioner will compare themaximum resistancemeasured in this period
with themaximum valuein theprevious 109 minutes andthebigger onewill beselected as resistance
