MODE button
Used to select the type of operation mode: Feel,
Cooling, Dry, Fan and Heating(Only for Heat Pump).
Note: Each mode and relevant function will be further specified in following pages.
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.

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.
(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: when the indoor pipe temperature is ≥50℃
Outdoor fan ON: when the indoor pipe temperature is ≤48℃
Compressor OFF: when the indoor pipe temperature is ≥62℃
Compressor ON: when the indoor pipe temperature is ≤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.

3. “COOLING” Mode Operation
(1) When the COOLING mode is selected without setting temperature, the system will set the set temperature at
℃ 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 16

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
set 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:
Set Temp. ＋1℃
Set Temp. －1
Room Temp.
Time
Compressor ON OFF ON OFF ON
Outdoor fan ON OFF ON OFF ON
(3) In HEATING mode, the indoor fan motor speed 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.
The vane angle is at the angle C(100°).

(5) Defrost
Defrosting of the outdoor heat exchange is controlled by the microprocessor with detection by the indoor
pipe temperature sensor.
Defrost control type is according to the JC on the PCB whether is connected.
When the JC is connect on the PCB
When one of the conditions of A, Band C is satisfy, the defrosting operation stars.
A. IPT--- indoor pipe temperature
In the condition A, it must satisfy the conditions a), b)and c) then into defrosting operation.
a) IPT1 satisfy IPT1=IPT
b) t5≥50minutes(the compressor cumulative operation time≥50 minutes, t5 is permitted move
and lower than t1 too).
IPT＜40℃，and keep 2 minutes.
c)
According to the condition A enter the defrosting operation, the first defrosting operation time is
8minutes; After defrosting operation one cycle, and then judge and regulate the defrosting operation
time.
B. After the compressor cumulative operation time exceeds 120 minutes and the temperature of the IPT
is less then 35
℃ for 2 minutes. When the defrosting operation time on this condition exceeds
－△IPT（8℃）
MAX
8minutes, it will terminate.
C. After the compressor operation continuously for 20 minutes and the IPT is less than 23℃ or from
the last time of defrosting operation is 50 minutes or more interval. When the defrosting operation
time on this condition exceeds 10 minutes, it will terminal.
When the JC isn’t connected on the PCB
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 pipe temperature 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 will terminal.
c) The outdoor defrost sensor reads 20
℃ or more.
d) The defrosting time exceeds 10 minutes.
