Remote Control
Note :
The remote controller is not presetting 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.
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. Automatic mode
1) The initial RT determines A/C working mode and the setting temperature (ST), the mode is
determined effective only once unless A/C shut-down and then re-started. If from other mode
switches to automatic mode (including mode conversion after shutdown), it should be that the
compress stop more than 3 min then temperature judgment and automatic mode are conducted (it
can conduct immediately from fan mode switched to automatic, the indoor fan stops, three minutes
later the response is made and start up). Within 3 min, the output as: Showing the room

5. Fan mode
1) Indoor fan motor is running at setting speed (the speed same as heating mode).
2) Vane motor control: running according to the setting condition.
3) The outdoor unit doesn’t work under fan mode.
6. Sleeping mode
1) Under sleep mode, the indoor fan motor running at low speed, except the power light and sleep
light are ON, timer lights ON/OFF according to the setting state, running light OFF. LED will be OFF
after displaying 30S.
2) Temperature control:
(1) While changing from Cool mode to Sleep mode, one hour later, the operation Temp.=ST＋1°C，
another one hour later, the operation Temp.=ST＋2°C，after then the temperature has no changed
anymore.
(2) When changing from Heating mode to Sleep mode, one hour later, the operation Temp.= ST-1°C,
another one hour later, the operation Temp.=ST-2°C,after then no changed anymore.
3) The machine will automatically shut up after running 10 hours under sleep mode.
When Timer ON and Sleep mode are implemented at the same time, the Sleep mode can not be
functioned.
7. Timer function
The timer can preset between 10min to 24h, when the time set less than “10” hours, the displayed
time shown by 0.5 hour as the unit, when the time set more than or equal to “10” hours, the
displayed time shown by 1 hour as the unit.
8. Emergency switch (ON/OFF)
1) When stand-by, to operate by pressing the emergency switch as follows:
Press the emergency switch within 3 seconds, release emergency switch while the buzzer rings once,
the machine goes into Cooling mode. If the buzzer rings twice while release emergency switch,
Heating mode is selected. To press the Emergency switch while A/C is on, the buzzer rings once and
then A/C will shut down.
2) The machine runs mandatorily as selected mode within 30min when Emergency operated,
meanwhile indoor fan motor runs in high-speed, and stepping vane swinging as well. 30min later
the A/C goes into automatic mode under the same operation manner, the set temperature to be
23°C, and the rotate speed of indoor fan motor automatic control, stepping vane swinging all the way.
3) To press the emergency button when the A/C goes on operation, then the machine runs into
stand-by.

Air Conditioner Service Manual
4) Under emergency operation, the function of compressor’s time-delay protection, Anti-frosting
protection in cooling mode, Overheating protection in heating mode, sensor fault protection and
defrost operate are effective.
5) Under emergency operation, once effective signal from remote controller received, the A/C
exits form of emergency mode without delay, and operates according to the setting value from remote
controller immediately.
9. Auto-restart function
1) The PCB retains the setting parameters in case of power off. When the power supply is resumed,
the machine, which has been started up the power-off memory function, is able to restore into the
original running state automatically.
To press the emergency button and power on the unit, and hold on for10 seconds, The buzzer
2) will ring three times, after this operation, the auto restart function activated.
3) To close auto restart function while it is activated, repeat process as above 2), the buzzer will ring
four times.
10. Protection / Failure code
10.1 Protection
1) Compressor’s protection:
a. The PCB which with Auto-restart function, once it is activated, the compressor goes along 3min
delay protection when power on, otherwise the compressor without this protection even when the PCB
is power-on.
b . The compressor’s 3 min interval protection: the compressor can’t start-up until it stops 3 min later.
(except for the defrosting process).
c. ．After the compressor started, it’s operation state remains the same within 3 min even when ST, RT
variation.
2) Anti-frosting protection of indoor evaporator (Cooling mode):
If IPT≤0°C detected in consecutive 3 min, compressor and outdoor fan motor to be stopped operation,
indoor fan motor runs at high-speed forcibly; i f IPT≥5°C detected 3min later, then outdoor fan motor
and compressor will start up, and indoor fan motor restores to it’s original state.
3) Overheating protection (Heating mode):
If IPT≥55°C, the outdoor fan motor: OFF.
If IPT≥65°C, the compressor: OFF, and indoor fan motor runs at
high-speed forcibly.
When IPT≤48°C, the outdoor fan motor and the compressor start up, indoor fan motor restores to it’s
original state.
4) Cold air prevention (Heating mode):
This function is intend to prevent cold air from being discharged when the heating operation starts or
when defrosting.
a. When running into the heating mode, once the compressor fails to comply with the start-up
conditions, the fan speed is regulated according to the coil temperature within 2 min, 2 min later the
indoor fan motor stops. If the compressor starts up within 2 min, then operating according to Figure 5.
Under heating process, while the compressor stop (including stopping for protection), the fan motor’s
operation (including stopping the indoor fan motor) is regulated according to the coil temperature
within 1min, 1min later the fan will be stopped forcibly.
10

b. When the indoor fan motor running at a low-speed under cold air prevention operation, once
auxiliary electric heating works, the vane immediately withdraws from the cold air prevention
location and turn back to normal vane angle. While auxiliary electric heating stops, indoor fan motor
goes on to run at low-speed accordingly, the vane turns to cold air prevention location
Figure 5 Cold air prevention
10.2 Failure code
The following table shows the fault protections.
When failures happens, the PCB alarms and buzzer rings three times, Failure code shows on
display board, and the PCB operates protection procedures.
Failure code: For the machine with LED display (88), the code shows on LED, for machine without
LED, the code reflects by the running light.

While failure happens, the code displayed statically, if there are several failure codes reported at
the same time, then failure codes appears by turns every eight seconds correspondingly.
6
a. Sensor’s failure protection: when the sensor tested temperature out of the range ---
50°C≤T≤110°C, sensor failure is determined.
Once RT and/or IPT sensor failure appears, the compressor stops, and indoor and outdoor fan
motors shut off. Remote controller doesn’t response to any signal except for shutdown. During failure
the machine can run in fan mode. After the failure is settled, the PCB restores to standby status.
7
b. Failure protection of Indoor PG fan motor: If there is no feedback signal of rotated speed within 5s,
the indoor fan motor stops, meanwhile, the compressor, outdoor fan motor, four-way valve and/or
auxiliary electric heater etc. also cut down.
The indoor fan motor restarts again 10 seconds later, if still there is no feedback signal of rotated
speed within 5 seconds, the A/C stops and goes into indoor fan motor failure protection, buzzer
rings three times, and running light flashes at 6 times per 8 seconds. Once there is feedback signal
while the failure recovery, the failure will relieve automatically.
