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.

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

(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.

8. “SLEEP” mode
When the SLEEP button is pressed, the SLEEP mode is selected as following:
The indoor fan speed is set at the low speed, the power lamp and the sleep lamp is on, the temperature off
after 5 minutes.
When selecting COOLING/DRY operation with SLEEP mode, the set temperature will be raised by 1
hour later and by 2℃ 2 hour later.
When selecting HEATING operation with SLEEP mode, the set temperature will be dropped by 1℃ 1
hour later and 2℃ 2hour later.
After the System operates in SLEEP mode for 8 hours, it will stop automatically.
9. Fan motor control
(1) Rotational frequency feedback control
The indoor fan motor is equipped with a rotational frequency sensor, and outputs signal to the
microprocessor to feedback the rotational frequency. Comparing the current rotational frequency with the
target rotational frequency, the microprocessor adjusts fan motor electric to make the current rotational
frequency close to the target rotational frequency. With this control, when the fan speed is switched, the
rotational frequency changes smoothly.
(2) When the rotational frequency feedback signal has not output for 5 seconds (or when the microprocessor
can’t detect the signal for 5 seconds), the fan motor is regarded locked-up. Then the electric current to the fan
℃ 1

The failure of indoor pipe temperature sensor Twice/cycle E2
The failure of indoor fan motor 6 times/cycle E6
c) Failure Handling
When the room temperature sensor or the indoor pipe temperature sensor is failure, the system will be
shut off, the compressor will be OFF, and the outdoor fan and the indoor fan will be OFF. The system
doesn’t receive the signal of remoter controller except the signal of shut off it. When the failure
disappear, the controller can operate in normal mode. before this, presses the “ON/OFF” to start the
system, and it will operate in COOLING or HEATING for 30 minutes, and follows shut off. During

this, it displays the failure and the protection is failing. You must be given the electric again to operate
it. In the failure, you can operate the FAN mode.
When the outdoor protects in the COOLING or DRY, the outdoor unit stops, the indoor fan operates in
set speed ; and in the HEATING, the outdoor unit stops, the indoor fan operates in cold air prevention
control. The system doesn’t receive the signal of remoter controller except the signal of shut off it.
When the system check the voltage is 220V and the delay control is finished, it operates at normal
again.
When the indoor fan motor is failure, the compressor is stopped, the outdoor fan and indoor fan is
stopped and display the failure. The system doesn’t receive the signal of remoter controller except the
signal of shut off it.
d) Display Of The Control
In the display board the lamp from left is the POWER lamp(Red), the SLEEP lamp(Yellow), the TIMER
lamp(Yellow), the RUN lamp(Green).
g) When gives the control electric, the buzzer voices a long for 0.3 second per cycle.
