Operation Details
Remote Control
The remote controller is not presetted as Cooling Only Air Conditioner or Heat Pump by manufacturer.
Each time after the remote controller replace batteries or is energized, the arrowhead will flashes on the front of
Heat or Cool on LCD of the remote controller.
User can preset the remote controller type depending on the air conditioner type you have purchased as
follows:
Press any button when the arrowhead flashes on the front of Cool , Cooling Only is set.
Press any button when the arrowhead flashes on the front of Heat , Heat Pump is set.
If you don t press any button within 10 seconds, the remote controller is preset as Heat Pump automatically.
Note :
If the air conditioner you purchased is a Cooling Only one, but you preset the remote controller as Heat Pump, it
doesn t bring any matter. But if the air conditioner you purchased is a Heat Pump one, and you preset the
remote controller as Cooling Only, then you CAN NOT preset the Heating operation with the remote controller.

Elctronic Controller
1. Safety Control
(1) Time Delay Safety Control
3 minutes delay for compressor---The compressor is ceased for 3minutes to balance the pressure in the
refrigeration cycle in order to protect the compressor.
2 minutes delay for 4-way valve---The 4-way valve is ceased for 2 minutes to prevent the
refrigerant-gas abnormal noise when the HEATING operation is OFF or switch to the other operation
mode.
20 seconds delay for indoor fan--- When the assistant thermistor turns off, the indoor fan operates in
low speed for 20 seconds to release the heat of indoor unit.
(2) Indoor Pipe Temperature Sensor Frost Prevention Control
When the indoor pipe temperature sensor reads 0℃ or below for 5 minutes, the indoor pipe temperature
sensor frost prevention control starts. The compressor and outdoor fan stop and indoor fan operates at high
speed for 3 minutes. After that, if the indoor pipe temperature sensor reads less than 5℃ this control
prolonged until the indoor pipe temperature sensor reads 5℃ or more.
(3) High Temperature Protection Control
During HEATING operation, the outdoor fan motor and compressor are controlled by the indoor pipe
temperature to prevent the high temperature of compressor.
Outdoor fan OFF: 52℃
Outdoor fan ON:48℃
Compressor OFF:62℃
Compressor ON:48℃
2. “I Feel” Mode Operation
(1) When the “I Feel” mode is selected, the operation mode and initial set temperature are determined by the
initial room temperature at start-up of the operation except to turn off the air conditioner and operates it
again.
(2) If the mode is change to “I Feel” mode from other mode, the “I Feel” mode doesn’t operate until compressor
stop for more than 3 minutes.
In the “I Feel” mode , when the controller receives the up or down single of temperature, the set
temperature can adjust by 1
℃ upper or lower. The biggest you can adjust by 2℃ upper or lower.
3. “COOLING” Mode Operation
(1) When the COOLING mode is selected without setting temperature, the system will set the set temperature at
26
℃ automatically with the AUTO FAN speed.
(2) When selecting the COOLING mode operation, the system will operate according to the setting by the
remote controller and the operation is as following:

4. “DRY” Mode Operation
(1) The system for DRY operation used the same refrigerant circle as the cooling circle.
(2) When the system operates in DRY mode ,at first it operates in cooling mode at 18
℃ for 3 minutes, and
then, the system operates in cooling mode with low speed that regards the temperature of the room
temperature sensor reads decrease 2℃ as the set temperature. During the course of this, the fan speed
setted operation is failing but the vane motor can be controlled.
5. “HEATING” Mode Operation (Only available for Heat Pump)
(1) When the HEATING mode is selected without setting temperature, the system will set the temperature at 23
℃ automatically with the AUTO FAN speed.
(2) When selecting the HEATING mode operation, the system will operate according to the setting by the
remote controller and the operation is as following:

(3) In HEATING mode, the indoor fan motor is controlled by Cold Air Prevention Control.
(4) Cold Air Prevention Control
The function is intend to prevent cold air from being discharged when the heating operation starts or
when defrosting.
The indoor fan speed will be controlled as following:

(5) Defrost
Defrosting of the outdoor heat exchange is controlled by the microprocessor with detection by the defrost
sensor.
Defrost starting conditions
When the conditions of a) or b) is satisfy, the defrosting operation starts.
a) Under the heating operation, the compressor cumulative operation time exceeds 50 minutes and the
temperature of the outdoor defrost sensor reads lower than －8
℃
b) Under the heating operation, the compressor cumulative operation time exceeds 50 minutes, if the
indoor pipe temperature sensor reads lower than 40
℃ continuously for 2minutes.
Note: If haven’t the outdoor pipe temperature sensor that use the condition b) to defrost, against
use the condition a).
Defrost terminating conditions
When the condition c) or d) is satisfy, the defrosting operation stops.
c) The outdoor defrost sensor reads 15
℃ or more.
d) The defrosting time exceeds 10 minutes.

(6) Assistant Thermistor Function
Assistant thermistor is add the thermitor of the electricity to rise the heating capacity automatically not
effected by the signal of the remote controller about assistant thermistor ON/OFF buttons.
1) When the condition all of A~G are satisfy, the assistant thermistor opens.
A. Under the heating operation, the compressor operates over than 3 minutes.
B. The indoor fan operates in normal.
C. The system operates not in defrosting.
D. The assistant thermistor turn off over than 30 seconds.
E. The set temperature is 3
℃ or more than the room temperature.
F. The room temperature sensor reads less than 22
℃.
G.
The indoor pipe temperature reads 43℃ or less.
2) When one of the conditions of A~E is satisfy, the assistant thermistor is off.
A. The compressor is turned off.
