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) Compre ssor’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-fro sting 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; if 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.

Air Conditioner Service Manual

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.

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.
