Note:
If POWER LED is blinking, the possible operation of the unit are Hot Start, during Deice operation, operation
mode judgment, or ON timer sampling.
If Timer LED is blinking, there is an abnormality operation occurs.
14.12 nanoe Operation
This operation provides clean air by producing great amount of negative ions and distribute through the
discharge airflow to capture or deactivate molds, bacteria or viruses.
Generate nanoe (water wrapped ion particle) to moisturize skin.
nanoe operation start condition
o During unit running at any operation mode, if nanoe operation is activated, combination operation (operation
mode + nanoe operation) starts.
o During unit is OFF, if nanoe operation is activated, nanoe individual operation starts.
nanoe operation stop condition
o When OFF/ON button is pressed to stop the operation.
o When nanoe button is pressed.
o When OFF Timer activates.
o When nanoe button is pressed.
o When OFF Timer activates.
nanoe operation pause condition
o When indoor fan stop (during deice, odor cut control, thermostat off, etc.). nanoe operation resume after
indoor fan restarts.
o When indoor intake temperature ≥ 35°C and < 5°C. nanoe operation resume after indoor intake temperature
< 35°C or ≥ 5°C continuously for 6 minutes.
Indoor
fan
control
o During any operation mode combines with nanoe operation, fan speed follows respective operation mode.
However, nanoe system enabled when fan speed ≥ 470 rpm to ensure proper negative ion distribution,
nanoe system disabled when fan speed < 470 rpm.
nanoe system disabled when fan speed < 470 rpm.
o During nanoe individual operation, only Auto Fan Speed and no Powerful operation is allowed. Even if Fan
Speed button is pressed, no signal is sent to the unit and no change on remote control display. Auto Fan
Speed for nanoe individual operation is cooling medium fan.
Speed for nanoe individual operation is cooling medium fan.
Airflow direction control
o During any operation mode combines with nanoe operation, airflow direction follows respective operation
mode.
o During nanoe individual operation, only Auto Air Swing is allowed. Even if Air Swing button is pressed, no
signal is sent to the unit and no change on remote control display.
Timer
control
o When ON Timer activates when unit stops, previous operation resumes and restored last saved nanoe
operation status.
o When ON Timer activates during any operation, no change on current operation.
o When OFF Timer activates during any operation, all operation stops and the latest nanoe operation status is
o When OFF Timer activates during any operation, all operation stops and the latest nanoe operation status is
saved.
Indicator
o When nanoe starts, nanoe indicator ON.

condition
Start from 1 sec after nanoe power ON, 6 secs has passed and in this 6 secs period, abnormal signal
is detected continuously for 5.9 secs.
Action after abnormal detection condition fulfilled
Disconnection counters +1, nanoe power OFF for 5 minutes and then restart. However, according to
action mode and disconnection counter, below will be implemented:
o During nanoe Check Mode: Disconnection abnormality will judged when disconnection counter
o During nanoe Check Mode: Disconnection abnormality will judged when disconnection counter
≥ 1. Abnormal code: H67 will memorized in EEPROM, Timer LED blinking and nanoe LED Off.
o Other Than Above: Disconnection abnormality will judged when disconnection counter ≥ 3.
Abnormal code: H67 will memorized in EEPROM and nanoe LED OFF, Timer LED not blinking.

Abnormal discharge counters clear condition
Discharge counter will be cleared when operation become normal for 50 mins above or when
operations stop.
14.13 Mild Dry Cooling Operation
This operation helps to prevent decreases in room humidity while maintaining the setting temperature.
During unit running at Cooling operation mode, if “Mild Dry Cooling” button is pressed, Mild Dry Cooling operation
starts and Mild Dry Cooling indicators turns ON at remote control display.
Mild dry cooling operation is unavailable when the unit is operating Auto mode and Soft Dry model operation.
Mild dry cooling operation is cancelled when the unit turned OFF, Mild Dry Cooling button is pressed again or
when the operation mode changed from Cooling to other mode.
ECONAVI, Powerful, Quiet and Mild Dry Cooling mode cannot function at the same time, the unit will follows the
operation according to the last signal received.
During this operation, the compressor frequency changes according to operating condition to prevent room
humidity decreases and when AUTO AIR SWING is set, the vertical airflow direction fixed at lower limit position.
14.14 ECONAVI Operation
Area of human availability, activity level and absent is judged based on pulses by using 2 infrared sensors. The
internal setting temperature shift, fan speed and horizontal airflow direction are adjusted in order to provide
comfort environment while maintain the energy saving level.
comfort environment while maintain the energy saving level.
ECONAVI start condition:
o When ECONAVI button is pressed.
ECONAVI stop conditions:
o When ECONAVI button is pressed again.
o When unit is OFF by OFF/ON button.
o When unit is OFF when OFF TIMER activates.
o When unit is OFF by AUTO OFF/ON button at indoor unit.
o When QUIET operation activates.
o When button is pressed.
o When POWERFUL operation is selected.
o When unit is OFF by OFF/ON button.
o When unit is OFF when OFF TIMER activates.
o When unit is OFF by AUTO OFF/ON button at indoor unit.
o When QUIET operation activates.
