8.2. Soft Dry Mode Operation
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 unit will 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 6 minutes.

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 unit is operating, operation will continue.
If current operation is in cooling mode (including the cooling mode operation when is a part of Soft Dry mode
operation) it will 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.

8.4. Air Circulation Mode Operation
1. An additional heater may make the warm air evenly covering each corner of the room.
2. When the temperature near the ceiling reaches the setting temperature, Air Circulation Mode Operation commences
at low airflow volume. It stops when the temperature drops to 2 below the setting temperature.
3. The vertical airflow direction louver will not swing.

The following conditions should be fulfilled
The initial MAXR after the preheating of the air quality sensor when the air conditioner is turned on:
The air conditioner will compare the maximum value of the current measuring period (MAX) with the
resistance reference 109 minutes before ( MAXR0) and select the bigger one as the current resistance
reference(MAXR).
When the air conditioner determines the air quality is getting worse: Air quality level 1 Air quality level 2,
MAXR will not be updated; When the air quality gets better (air quality level 0), Rs detected at this time will be
MAX and MAXR.
The air conditioner will not detect the air quality during deicing operation. The indication prior to the deicing
operation will be held during the deicing operation.
(d)
(e)
(f)
Basic Operation
Detecting and indicating of the air quality will not stop during the operation of the air conditioner.
The power of the air quality sensor is always 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 air quality
sensor intermittently (It will be on for 3 minutes after each 109 minutes.) for the purpose of air quality detecting.
Within 2 minutes after the air conditioner starts to operate, the air quality sensor is in the process of preheating
and the air quality indicator is red.
Resistance Reference
Detecting of air quality( During the operation of the air conditioner)
(a) The measuring period is 20 minutes; The air conditioner will measure the resistance (Rs) of the air quality
sensor once each 2 seconds and record the data. The maximum Rs within the 20 minutes will be selected as
Rs(MAX) for this measuring period.
(b) Suppose the current Rs(MAX) as MAX and the resistance reference of the previous measuring period is as
MAXR1.; If MAX>MAXR1, the resistance reference of the current measuring period is MAXR=MAX; If
MAX<MAXR1, MAXR=MAXR1;
(c) Within 2 minutes after the power of the air quality sensor is turned on, the resistance reference of this
measuring period is the maximum resistance of the sensor during this period.
19
Resistance of air quality sensor: Rs(air)=10k ~50k ( The worse the air quality, the smaller the resistance.)

Air Quality Control
Detecting of air quality(When the air conditioner is on standby.)

accordance with the value below,

Detecting of air quality( When the air conditioner is on standby.)
(a) After the air conditioner stops operation, it will provides power to the air quality sensor intermittently to detect
the air quality and update the resistance reference (MAXR). The power of the air quality sensor will be on for 3
minutes after each 109 minutes.
During these 3 minutes, the air quality sensor will be in preheating process for 2 minutes and the other time is
for measuring the resistance. The air conditioner will compare the maximum resistance measured in this period
with the maximum value in the previous 109 minutes and the bigger one will be selected as resistance
