[3] FUNCTION
1. Restart control
5. Indoor unit overheat prevention control
Once the compressor stops operating, it will not restart for 180 seconds to protect the compressor.
During heating operation, if the temperature of the indoor unit heat
exchanger exceeds the indoor unit heat exchanger overheat prevention temperature (about 45 to 54°C) which is determined by the operating frequency and operating status, the operating frequency is
decreased by about 4 to 15 Hz. Then, this operation is repeated every
60 seconds until the temperature of the indoor unit heat exchanger
drops below the overheat protection temperature.
Therefore, if the operating compressor is shut down from the remote
control and then turned back on immediately after, the compressor will
restart after a preset delay time.
(The indoor unit will restart operation immediately after the ON switch
is operated on the remote control.)

If the temperature of the indoor unit heat exchanger exceeds the overheat protection temperature for 60 seconds at minimum operating frequency, the compressor stops operating and then restarts after about
180 seconds, and the above mentioned control is repeated.
Compressor ON
6. Outdoor unit overheat prevention control
During cooling operation, if the temperature of the outdoor unit heat
exchanger exceeds the outdoor unit heat exchanger overheat prevention temperature (about 55°C), the operating frequency is decreased
by about 4 to 15 Hz. Then, this operation is repeated every 60 seconds until the temperature of the outdoor unit heat exchanger drops to
about 54°C or lower.
2. Cold air prevention control
When the air conditioner starts up in heating mode, the indoor unit fan
will not operate until the temperature of the indoor unit heat exchanger
reaches about 23°C in order to prevent cold air from blowing into the
room.
Also, the indoor unit fan operates at low speed until the temperature of
the indoor unit heat exchanger reaches about 38°C so that people in
the room will not feel chilly air flow.
Once the temperature of the outdoor unit heat exchanger drops to
about 54°C or lower, the operating frequency is increased by about 4
to 10 Hz every 60 seconds until the normal operation condition
resumes.
Indoor unit heat exchanger temperature
Set fan speed
If the temperature of the outdoor unit heat exchanger exceeds the outdoor unit heat exchanger overheat protection temperature for (120
sec.: outdoor temperature ≥ 40°C, 60 sec.: outdoor temperature <
40°C) at minimum operating frequency, the compressor stops operating and then restarts after about 180 seconds, and the above mentioned control is repeated.

7. Compressor overheat prevention control
21
Indoor unit fan in non-operation
If the temperature of the compressor exceeds the compressor overheat prevention temperature (110°C), the operation frequency is
decreased by about 4 to 10 Hz. Then, this operation is repeated every
60 seconds until the temperature of the compressor drops below the
overheat protection temperature (100°C).
3. Indoor unit heat exchanger freeze prevention control
If the temperature of the indoor unit heat exchanger remains below
0°C for 4 consecutive minutes during cooling or dehumidifying operation, the compressor operation stops temporarily in order to prevent
freezing.
Once the temperature of the compressor drops below the overheat
protection temperature, the operating frequency is increased by about
4 to 10 Hz every 60 seconds until the normal operation condition
resumes.
When the temperature of the indoor unit heat exchanger rises to 2°C
or higher after about 180 seconds, the compressor restarts and
resumes normal operation.
If the temperature of the compressor exceeds the overheat protection
temperature (for 120 seconds in cooling operation or 60 seconds in
heating operation) at minimum operating frequency, the compressor
stops operating and then restarts after about 180 seconds, and the
above mentioned control is repeated.
4. Outdoor unit 2-way valve freeze prevention control
8. Startup control
If the temperature of the outdoor unit 2-way valve remains below 0°C
for 10 consecutive minutes during cooling or dehumidifying operation,
the compressor operation stops temporarily in order to prevent freezing.
When the air conditioner starts in the cooling or heating mode, if the
room temperature is 2°C higher than the set temperature (in cooling
operation) or 3.5°C lower (in heating operation), the air conditioner
operates with the operating frequency at maximum. Then, when the
set temperature is reached, the air conditioner operates at the operating frequency determined by fuzzy logic calculation, then enters the
normal control mode after a while.
When the temperature of the 2-way valve rises to 10°C or higher after
about 180 seconds, the compressor restarts and resumes normal
operation.

9. Peak control
14. Power ON start
If the current flowing in the air conditioner exceeds the peak control
current (see the table below), the operation frequency is decreased
until the current value drops below the peak control current regardless
of the frequency control demand issued from the indoor unit based on
the room temperature.
If a jumper cable is inserted in the location marked with HAJP on the
indoor unit control printed circuit board (control PCB), connecting the
power cord to an AC outlet starts the air conditioner in either cooling or
heating mode, which is determined automatically by the room temperature sensor.

The compressor stops immediately after cooling, dehumidifying or
heating operation is shut down, but the outdoor unit fan continues
operation for 50 seconds before it stops.
When the air conditioner is in non-operating condition, holding
down AUX button for more than 5 seconds activates the malfunction code display function.
11. Defrosting
11.1. Reverse defrosting
The operation continues only in the case of a serial open-circuit,
and the main relay turns off after 30 seconds if the open-circuit condition remains.
The defrost operation starts when the compressor operating time
exceeds 20 minutes during heating operation, as shown below, and
the outside air temperature and the outdoor unit heat exchanger temperature meet certain conditions. When the defrost operation starts,
the indoor unit fan stops. The defrost operation stops when the outdoor unit heat exchanger temperature rises to about 10°C or higher or
the defrosting time exceeds 10 minutes.
20 min or more
20 min or more
In the case of a serial short-circuit, the air conditioner continues
operating without a malfunction code display, and the main relay

29.1. PFC Module
In the case the direct current is obtained by the diode bridge and smooth capacitor from the commercial power source, the current wave shape will be
the pulse shape at the peak of the voltage wave shape as shown in the figure below. For this reason, the harmonic current will be generated and at
the same time the power factor will be deteriorated. While monitoring the AC input voltage in the control circuit, in order to be the same phase and
wave shape as this voltage wave shape, IGBT is made ON/OFF by the carrier frequency of approximately 20 kHz. By adoption of this PFC Module,
the current wave shape can be made to the sine wave synchronized to the commercial power source and the power factor can be made to almost
99%. As a result of this, reactor can be disused. PFC Module works for the improvement of power factor and as the countermeasures for the harmonic current.

29.2. PFC Module Voltage Raise Circuit
The IGBT in the figure below is the switching transistor of the PFC Module. By adding ON signal to the gate of IGBT from the control IC, IGBT turns
ON and the collector current Ic flows. This current flows from the + side of the diode bridge DB to the Choke coil, the - side of the diode bridge DB
through IGBT from the Choke coil L. At this time, energy is stored in the choke coil L. Next, when gate signal of IGBT turned OFF, IGBT will be turned
OFF and the energy stored in L during the ON time of IGBT will be discharged through the diode D, electrolytic capacitor C, load, primary side and the
+ side of DB. Assuming the input voltage of PFC Module (voltage between + and - of DB) as Ei, the output voltage (voltage at the both ends of smooth
capacitor) as Vo, switching cycle of IGBT as T and ON time of IGBT as ton, the voltage between collector emitter of IGBT Vs will be as follows;
Vs= 0 (during ON of IGBT: ton)
Vs= Vo (during OFF of IGBT: T-ton)
Here, assuming no loss in L and IGBT, average value of Vs turns equal to Ei,
Ei = (T-ton)/T x Vo
Therefore
Vo = T/(T-ton) x Ei
As ton is a smaller value than T, output voltage Vo will be higher than input voltage Ei.

29.3. PFC Module Driving Electronics Circuit
The PFC Module circuit operates continuously while the compressor is driving.
The microcomputer detects output DC voltage of the PFC Module circuit with pin 69, and controls to keep the DC voltage to be the target value.
The microcomputer controls so that the input AC current wave form will become a sine wave detecting the input AC voltage of the PFC Module circuit
with pin 71 and detecting AC current wave form with pin 72.
The microcomputer calculates to do above mentioned controls, and outputs the PFC signal (ON/OFF duty control of 20kHz) from pin 89. The PFC
signal is input to IN of PFCM, and the PFC Module circuit operates.
29.4. Output voltage of PFC Module
The output DC voltage of the PFC Module circuit changes within the range from 310V to 370V in proportion to the voltage value of the power supply.
When the power supply voltage is AC 230V, the output DC voltage is DC 330V.

[1] TROUBLESHOOTING GUIDE
1. SELF-DIAGNOSIS FUNCTION AND DISPLAY MODE
1) To call out the content of the self-diagnosis memory, hold down the emergency operation button for more than five seconds when the indoor unit is
not operating.
a) According to the content of the self-diagnosis memory, the Operation LED (main category) and the Plasmacluster Ion LEDs (sub-category)
flash in sync with the Timer LED on the indoor unit.
b) In the event a complete shutdown occurs due to a malfunction, the Operation LED (red), Timer LED (yellow) and Plasmacluster Ion LED (blue)
flash to indicate the general information of the generated malfunction.
c) If the power cord is unplugged from the AC outlet or the circuit breaker is turned off, the self-diagnosis memory loses the stored data.
2) Display of detailed self-diagnosis result with main category and sub-category indications
When malfunction information is called out, the main category and sub-category of the self-diagnosis result are indicated by the Operation, Timer,
and Plasmacluster Ion LEDs on the indoor unit.

CHAPTER 5. DISASSEMBLING PROCEDURE
AYXPC18LR
Manual
If, in carrying out repairs and modifications, the work requires the use of arc- and flame-producing apparatus, such as welding, brazing and soldering
equipment, this work shall only be started after the rooms have been thoroughly ventilated. While the work is being carried out, the mechanical ventilation, if any, shall be kept in constant operation and all windows and doors kept open. In the case of repairs to parts of the refrigerant circuit, it may
be necessary that not only the workman but also a second person shall be present for observation and assistance.
Necessary protective equipment shall be available and, in the case of open flames or arcs, fire extinguishing apparatus shall be ready to hand.
Welding and brazing shall be carried out by qualified workmen.
Be sure to disconnect the power cord from the AC power outlet before starting the disassembly procedure. When reassembling the unit after repairing, be sure to install screws to their original positions.
The screws used are not the same in specifications such as corrosion-resistant treatment, tip shape and length.
After the air conditioner is repaired or parts are replaced, measure insulation resistance of the equipment using an insulation resistance meter. If the
measured resistance is lower than 1 MΩ, inspect parts and repair or replace defective parts.
