7.1.10 Electrical wiring 1. The system uses one two-core communication wire, all of the indoor communication wires

are connected to this wire in parallel. “C1”, “C2” are non-polar, when wiring, please pay

attention that they must be separate with the power wire, in order not to make the

interfering signal.

2. When pressing the power wire, please pay attention that the interior diameter of loop

terminal should be more thanφ5.5, in order not to press it firmly.

3. The max. current can be up to 42A, and power can be up to 7.5KW. So when selecting the

electric parts and air breaker, the data should be 1.5 times than the nominal.

4. Because the indoor unit adopts EEV control method, when a sudden power off occurs, the

EEV maybe keep some angle. If indoor unit and outdoor unit connect to power supply

separately, when some indoor units running in cooling mode, when powered off, because

the EEV does not reset, the indoor units maybe drop water, ice up. We recommend that the

indoor unit connect to power supply from the outdoor unit, or use one power supply with the

outdoor unit. If the indoor unit need connect power supply individually, the personnel must

explain to the customer that he (she) must switch off the unit with wired controller or remote

controller, then he (she) can shut off the indoor unit. If there is accidental power failure,

please firstly power on all the indoor units after power on, in order to reset the indoor EEV.

Defects from improper installations can be the cause of water leakage electric shocks and fires.Execute the installation accurately, based on following the installation manual. Again improperinstallations can result in water leakage, electric shocks and fires.Please install your air conditioner on a wall or any place which can holder the weight of theair conditioner. And it cannot be installed on a non-professional metal structure (such as aburglary-resisting net). Otherwise injury would occur due to a falling of the unit.Execute the prescribed installation construction to prepare for earthquakes and the strong airsof typhoons and hurricanes, etc. Improper installations can result in accidents due to a violentfalling over of the unit.Wiring shall be done with the specified cable and the connection shall be firm and reliable.And the terminal connector shall be fixed firmly and reliably not to let external force exerciseon the cables. Any improper connection or fixing would cause heat, fire, and other accidents.Wiring shall be done in a correct shape not to make any section rise upward, and accuratelyinstall the air conditioner. The cable shall not be clamped by the lid or outer plate. Anyimproper installation would lead to fire, heat, or other accidents.

When setting up or moving the location of the air conditioner, do not mix air etc, or anythingother than the designated refrigerant (R407C) within the refrigeration cycle, for such mixingwould result in rupture and injury caused by abnormal high pressure. Always use accessory parts and authorized parts for installation construction. Using parts notauthorized by this company can result in water leakage, electric shock, fire and refrigerantleakage.The drain pipe must not be placed or connected into the sewage tank where harmful gas suchas sulphurous gas and etc would exist, otherwise the harmful gas would enter the room.During installation, if the refrigerant is leaked, please immediately take measures ofventilation, otherwise a harmful gas would be generated whenever the refrigerant meets fire.After installation, please ensure that the refrigerant is not leaked, because the leakage ofrefrigerant would produce a harmful gas if it meets fire or heating stoves.Don't install the air conditioner where a flammable gas would be probably produced,otherwise in case the flammable gas is leaked and exists around the unit, fire would be caused.For the drain pipe, follow the installation manual to insure that it allows proper drainage andthermally insulate it to prevent condensation. Inadequate plumbing can result in waterleakage and water damage to interior items.The refrigerant gas pipe and liquid pipe shall all be thermally insulated to preserve the temperature. Any improper insulation would make the unit moist and the water would droponto the floor or wet the indoor items.

8. Electric control functions8.1 Electric control functions of AU242FHBHA and AU482FIBHA 1. Startup control of compressor 1) Protection at startup In order to prevent the constant startup of compressor, and keep the pressure balance of the system, within 3 minutes after compressor shuts off, please do not enter the thermostat OFF state, 3 minutes later, if the unit is at thermostat ON state, the compressor can re-start up. In 10 minutes after compressor shuts off, in order to keep pressure balance, the solenoid valve SV1 will open. 2) Soft startup In order to protect the compressor and the transducer, when startup, the unit will decrease the startup load. Entering condition: In heating mode, after the 4-way valve operation is over, it enters soft startup. After the defrosting is over in heating, it enters soft startup. 2. Outdoor fan motor control 1) If fan motor starts up at high speed, running for 30 seconds later, it will change speed. 2) Compressor shuts off, outdoor motor will shut off after running at low speed for 30 seconds. 3) Temperature control difference is ±1degree, the interval of speed change is over 45 seconds. 3. Heater control If ambient temperature TA≤27degree, heater will be electrified when compressor stops. If TA≥27degree, or when compressor starts up, heater is not electrified, the temp. difference is 5 degree. 4. Defrosting control In heating mode, defrosting sensor TE will check the frost state of outdoor heat exchanger to control the defrosting. 5. 4-way valve reliable operation control 1) Purpose: reliable conversion of 4-way valve 2) Startup control

a. If 4-way valve not being electrified before starup, the 4-way valve will convert directly. In heating mode, after the outdoor unit receives the startup signal from indoor unit, the compressor will start up and enter the soft startup period directly.

b. If 4-way valve is electrified before startup, the unit will enter reliable operation control. 6. Unloading valve SV1 control According to the operation, the 2-way valve will be controlled as follows: 1) Before or after the compressor starts up, SV1 will make unloading operation. The detailed is the

following: SV1 opens 1 minutes before compressor starts up, and keep open in the soft startup period until the soft startup is over; In other period and 10 minutes after the unit shuts off, SV1 opens.

2) Any protections, SV1 opens. 7. Refrigerant spray valve SV2 control According to the compressor discharging overheat state, open time of SV2 will be controlled. 8. Discharging temperature sensor TD, suction temperature sensor TS When compressor stops and in 5 minutes after the compressor starts up, the TD abnormal value is ignored. TS is not ignored. According to the temperature measured by TD, TS, the unit will make by-pass control when the discharging temperature is overheat.

-98-

9. Heat exchanger temperature sensor TE, which will work in defrosting 1) According to temp. measured by TE, make the defrosting operation. 2) According to temp. measured by TE, make the fan speed control in heating. 10. Oil return operation in cooling When indoor unit receives oil return signal, oil return operation will begin. The compressor will keep a certain frequency, and quit 4 minutes later, then sends oil return over signal to indoor unit. 11. Refrigerant return control in heating In this operation, compressor keeps running and some indoor thermostats are OFF for 60 minutes, also meets the other conditions, the function will work. 12. Remains heating operation ( used to protect compressor) Purpose: avoid too much refrigerant stays in gas-liquid segregator, which results in compressor difficult startup the next time. In heating mode, after outdoor receives the shutoff signal from indoor, the unit will enter remains heating operation ( the shutoff which results from communication malfunction between indoor and outdoor, needs remains operation; the other protective shutoff will not make remains operation.) 13. Rating operation (only in debugging) Rating operation: indoor capacity is fixed, compressor frequency depends on the total indoor capacity and can be adjusted by hand. In this period, the frequency can be increased or reduced. 14. Current value has 3 stages. Current is over A, frequency will increase to the target frequency; Current is between B and C, frequency will decrease; current is below B, at the beginning, it not rises, then rise slowly, when it is over B, stop rising to decrease frequency operation. Peak current is over C and keep it for a period, the unit will be standby state, meanwhile, sends out the failure signal. If running for another 30 minutes, current is over C again for a period, the compressor stops, and sends out failure signal. 15. High pressure switch protection If the pressure switch output is 1 (high level), there is no protection. If the pressure switch output is 0 (low level) for a period, the unit enters high pressure protection. Compressor will stop and send out alarm signal. The alarm is solved, the system can resume, in 3 minutes when compressor is standby, there is still alarm. 16. Low pressure switch protection If the pressure switch output is 1 (high level), there is no protection. When compressor is running, if low pressure switch is OFF for 3 minutes, the unit will alarm. When compressor stops, if low pressure switch is OFF for 30 seconds, the unit will alarm. When compressor starts up, in 3 minutes, low pressure switch is shielded. In defrosting and within 6 minutes when defrosting is over, low pressure switch is shielded. 17. Time shorting function (usually used in debugging) As long as one indoor unit is in time shorting, the outdoor will enter 1/60 second time shorting function. Outdoor is equipped with timeshorting port, if this port is disconnected, it will enter time shorting too.

8.2 Electric control functions of AU48NFIBIA 1. Capacity control of compressor Operation mode: entering earlier in prior, cooling and heating can not operate simultaneously. In cooling, the output frequency of the transducer depends on the indoor capacity request and the outdoor ambient temperature; in heating, firstly the indoor capacity request and the outdoor ambient temperature will confirm the base frequency, then the indoor evaporator temperature will adjust the output frequency of the transducer. The indoor capacity request can be calculated as per the capacity and the temperature difference between the set temperature and the indoor actual temperature. Low frequency protection: When the horse power of all running indoor unit is over 2HP, after the output frequency stays for 15 minutes at 30Hz, then the output frequency will arise to 40Hz and run for the time of low_f_prot_t, then the frequency will resume to the target frequency. High frequency protection: After the output frequency runs for 15 minutes at over 110Hz, the output frequency will reduce to 100Hz and run for 5 minutes, then it will resume to the target frequency. 2. Startup control of compressor 2.1 Protection at startup In order to prevent the constant startup of compressor, and keep the pressure balance of the system, within 3 minutes after compressor shuts off, please do not start up the compressor, 3 minutes later, the compressor can re-start up. 2.2 Soft startup ( 3 minutes) In order to protect the compressor and the transducer, when startup, the unit will decrease the startup load, and operate as follow: Within 3 minutes after the compressor starts up, the unit runs at the fixed low frequency of 50Hz to prevent the liquid type refrigerant being sucked into the compressor. Open solenoid valve to make it pass by, and run with low load. 3 minutes later, the unit will run at the target frequency. 2.3 Reducing-pressure startup In heating, when compressor stops, the refrigerant will remain in the gas-liquid segregator, in order to prevent the blocked liquid at the next compressor startup, the compressor will make reducing-pressure startup. After the gas-liquid segregator is dry completely, the compressor will operate normally. 2.4 Pre-heat startup in heating mode Because the compressor does not run for long time and the refrigerant does not circle, when re-startup, it will cause refrigerant foam resulting in the compressor lack of oil, so the pre-heat can ensure that low pressure will not reduce too much. 3. Outdoor EEV control If reset when being electrified on, EEV is close totally, -500 pulses. When in shutoff, or in cooling, in defrosting, EEV is open totally, 480 pulses. When in oil return operation in heating mode, the open angle of EEV is the base angle of 6HP unit. In normal heating mode, EEV will confirm a base angle as per the indoor capacity request, then according to the overheat value, the system can micro-adjust the angle. In heating the adjustment of EEV: 3.1 The min open angle is no less than 80, and the max open angle is no more than 350 3.2 After the soft startup is over, EEV will confirm the target overheat value due to the outdoor ambient temperature

4.4 Defrost period: outdoor fan motor shuts off. 5. Electric heater control

-101-

If Ta ≤27, when compressor stops, electric heater is electrified on. When Ta ≥32, or compressor starts up, electric heater is not electrified. 6. Defrost control In heating mode, the defrosting sensor Te will check the frost state of outdoor heat exchanger, to control defrosting function. 6.1 Defrosting beginning conditions In heating mode, if the compressor has run for 45 minutes in all, by checking the defrosting sensor Te and outdoor ambient temperature sensor Ta, the unit will enter defrost operation: When Ta ＜2, if for 2 minutes contineously Ta-Te≥9, or for 5 minutes contineously Te＜12, the unit will enter defrost. When Ta ≥2, if for 5 minutes contineously Te＜-5, the unit will enter defrost. 6.2 Defrosting finish conditions The defrost operation will be over 10 minutes later after defrost begins. By checking the outdoor defrosting state through Te, if Te is over 7 for over 60 seconds in all or Te reaches 12, defrost will finish. 6.3 Protection during defrost A: Pressure switch not work B: Protection to temperature sensors is cancelled 6.4 Measures after defrosting: If the defrost is over, the adjustment of the solenoid valve and the current can be treated as the adjustment when compressor starts up. 7. Control of refrigerant spray valve SV2 Control of refrigerant spray: according to the overheat state of compressor discharging, the unit will control the open time of SV2. 7.1 Control conditions A. In cool/heat/dry mode, SV2 can be controlled. B. Within soft startup period (3 minutes) after compressor starts up, the abnormal suction temp.,

discharging temp. of compressor will be ignored. 7.2 After compressor starts up for 3 minutes, according to the overheat state of compressor discharging, perform as follow: If the discharging temp. is overhigh, the spray valve will open; while overlow, it will close. 8. Unloading valve SV1 According to the operation state, the open/close control of unloading valve will be as follow: Unloading valve SV1: Before or after compressor starts up, it will make unloading operation. In the compressor soft startup period, SV1 opens; after soft startup is over, SV1 closes. If compressor shuts off, SV1 opens and will delay 10 minutes to close. In heating, Ta ＞17, and running indoor HP ≤1HP, SV1 will open or close according to the discharging temp. and the coil temp. 9. Discharging temperature sensor Td Within 3 minutes after compressor begins soft startup or the unit receives the stop-compressor signal, the abnormal value of Td, Ts will be ignored. Due to the measured temperature by Td and Ts, the unit will make by-pass control when the discharging temperature is overheat.

-102-

9.1 According to the temperature measured by Td, the unit will adjust compressor frequency when discharging temperature is overheat. When spraying refrigerant cannot efficiently decrease discharging temperature, the system will make decrease-frequency protection. 9.2 When Td is over 110, the frequency will reduce 10Hz for every 120 seconds. When the output frequency has become the low limit, Td is still over 110, the unit will stop. 10. Oil return operation 10.1 Oil return operation in cooling Entering condition: Indoor thermostat OFF time is over 30 minutes (after oil return operation, time again from beginning). In cooling mode, compressor runs for 1 hour in all (after oil return operation, time again from beginning). Operation procedure: After oil return signal has been sent to indoor for 30 seconds, the unit will begin oil return operation. Compressor running frequency is the oil return frequency, outdoor EEV open angle does not change and quit oil return 4 minutes later, then resume the frequency before oil return operation, finally, send oil return finish signal to indoor unit. 10.2 Oil return operation in heating Entering condition: Indoor thermostat OFF time is over 30 minutes (after oil return operation, time again from beginning). In heating mode, compressor runs for 1 hour in all (after oil return operation, time again from beginning). Operation procedure: After oil return signal has been sent to indoor for 30 seconds, the unit will begin oil return operation. Compressor running frequency is the oil return frequency, outdoor EEV open angle is the special angle for heating oil return and quit oil return 4 minutes later, then resume the corresponding base angle due to the indoor capacity. 11.

When input of pressure switch is 1 for 1 minute, that shows high pressure protection, and compressor stops, then there will be failure alarm signal. If alarm has been solved, the protection

-103-

will resume, but in 3 minutes of compressor standby, alarm will exist. 13. Jumping frequency point design Avoiding the frequency point of pipe vibration, we design the jumping frequency function. 13.1 4 jumping frequency points F0; 1 jumping frequency range ∆F. 13.2 The point value and the jump rang will be saved in EEPROM. 13.3 Output frequency will be changed under the below conditions: In speed up/down period, jumping frequency function does not work, only after the frequency is steady, if the output frequency is in the jumping frequency range, this function will work, so the final output frequency is (jumping frequency point value-jumping frequency band) 14. Time shorting function As long as one indoor unit is in time shorting, the outdoor will enter 1/60 second time shorting function. 15. Oxygen generator control Entering condition: 15.1 Oxygen request from indoor unit 15.2 Ambient temperature over 4

8.3 Indoor unit electric control functions 1. Cooling mode 1.1 Temperature control range: 16~30, and the precision is ±1 1.2 Characteristic of electronic expansion valve (EEV) After EEV opens (base angle is 200), in 5 minutes, it will not be controlled by thermostat OFF, but controlled by the overheat value. In this period, if thermostat is OFF, no response, when it is 5 minutes, the unit will send the signal of Area 0. In 5 minutes, if the remote controller shuts off the thermostat and the unit, at this time, the unit will not be limited by the overheat value, and you can set the EEV at the standby open angle and emit the signal of Area 0. 1.3 Fan motor control Temperature difference 1 Auto speed: In cooling mode TA-TS

+2 high +1 med 0 low

After the thermostat is OFF, EEV will be controlled by fan motor: set EEV at the standby open angle, fan motor is low speed. 1.4 Set temperature compensation How to change temp. compensation: By using the SWING button (if no SWING, use SLEEP) to set EEPROM, for example: in heating mode, press “ON/OFF” button, taking set temperature 24 as base point, at this temperature press SWING (SLEEP) button 7 times within 5 seconds, the buzzer sounds two times and enters the temp. compensation set mode in heating, at this time, if you shut off the unit when the adjusted temperature is 25, the temp. compensation is +1. If you shut off the unit when the adjusted temp. is 26, the temp. compensation is +2, and so on. The max temp. compensation is 6(adjusted temp. is 30). And if you want to cancel temp. compensation, set the temperature back to 24. In cooling mode, press “ON/OFF” button, taking set temperature 24 as base point, at this temperature press SWING (SLEEP) button 7 times within 5 seconds, the buzzer sounds two times and enters the temp. compensation set mode in cooling, at this time, if you shut off the unit when the adjusted temperature is 23, the temp. compensation is -1. If you shut off the unit when the adjusted temp. is 22, the temp. compensation is -2, and so on. The max temp. compensation is -8(adjusted temp. is 16). And if you want to cancel temp. compensation, set the temperature back to 24. The above are for remote control type. If at wired control type, the temp. compensation function is set in EEPROM, and fixed as 4 when out of factory. 1.5 Anti-freezed protection

-105-

Closing the cycle can avoid indoor freezing. When the temperature measured by the indoor coil temperature coil is too low, the unit will enter anti-freezed operation and be set under the below conditions. Anti-freezed operation start condition: If accumulative operation time is over 10 minutes at one temperature, the system will make the thermostat OFF compulsorily until the anti-freezed function can reach stop condition. Anti-freezed operation stop condition: The time is over 10 minutes when the temperature rises upto one certain temperature. 2. Dry operation mode 2.1 Temeprature control range: 16~30, and control precision: ±1 2.2 Characteristic of electronic expansion valve (EEV): as the same as that of cooling mode. 2.3 Fan speed control Auto: Tr>Ts+1 high speed Ts+1>Tr≥Ts low speed Ts>Tr stop fan motor in 3 minutes, 3 minutes later, low speed When fan speed changes from low to high,there is no delay, and when changing from high to low there is 30-second delay. Thermostat OFF: fan motor stops in 3 minutes, meanwhile the valve goes back to standby angle, and 3 minutes later, it is low speed. Fan speed adjustment by hand: when unit is running, you can set High/Med/Low/Auto speed due to request. 2.4 No temperature compensation in Dry mode 2.5 Anti-freezed protection: as the same as that of cooling mode. 3. Heating mode 3.1 Temeprature control range: 16~30, and control precision: ±1 3.2 Characteristic of electronic expansion valve (EEV): as the same as that of cooling mode, but the open angle is different. 3.3 Fan speed control Auto speed:

Heat mode:

TA-TS +1 Super low speed 0

low speed -1 med speed -2

high speed When fan speed changes from low to high,there is no delay, and when changing from high to low there is 30-second delay. Thermostat OFF: EEV delays to close, after the fan motor enters super low speed, the thermostat will be OFF.

-106-

Fan speed adjustment by hand: when unit is running, you can set High/Med/Low/Auto speed due to request. 3.4 Temperature compensation In 5 minutes of first startup(or cancel temp. compensation for the first time), 4 temp. compensation is cancelled. When out of factory, the compensation is set at installation. The others are as the same as that of cooling mode. 3.5 Anti-cold air operation When the temperature reaches one value, fan motor is low speed, and rises over one value, you can set the fan speed; while when the temperature lowers one value, fan motor is low speed, and lowers another value, fan motor stops. 1) When beginning heating mode, if indoor liquid pipe temperature is below a certain temperature,

indoor fan motor will stop; if indoor liuiqd pipe temperature is over a certain temperature, fan motor will be in low speed.

2) If indoor liquid pipe temperature can not be over a certain temperature, fan motor will not run. If indoor liquid pipe temperature can be over a certain temperature, fan motor will run at set speed.

4. EEV control 4.1 General control: After the unit is powered on, EEV will make full close and full open action, then be at full close standby state. When thermostat is ON, and the unit starts up after defrost, EEV will be at base open angle. The base angle when thermostat is ON for first time: cooling: 200 pulse, heating: 350 pulse. 4.2 In cooling, modify the base open angle according to the indoor coil temp., and discharging temp. 4.2.1 Correction of Overheat value The function can work in 4 minutes after starting up in cooling, including startup of the protective stop. The adjustment interval depends on the compressor running frequency, as below:

Frequency(Hz) 30-40 40-60 60-90 and more Interval (s) 30 20 10

4.2.2 Correction of discharging temperature The function can work in 4 minutes after starting up in cooling, including startup of the protective stop. 4.3 In heating mode, the base open angle depends on the pipe temperature conformity The indoor EEV open angle depends on the temperature difference between the liquid pipe temperature in heating and the average indoor liquid pipe temperature. 5. Electric control functions 5.1 Fan operation Indoor fan motor will run at the fan speed set on the wired controller, meanwhile sends stop signal to outdoor unit. 5.2 Timer function You can set the 12-hour Timer ON/OFF as your need, the min. time unit is 10 minutes. After setting the timer, the timer lamp on the unit is on; when timer is over, the timer lamp is off, there are the following timer states: Timer ON: Power LED, OFF; Run LED, OFF; Timer LED, On and at stop state. When timer is over,

the fan begins running and the timer LED is OFF. The operation begins from receiving the timer signal for the first time.

-107-

Timer OFF: When startup, timer LED is on, when timer is over, the timer LED is off and meanwhile, the unit stops. Timer ON/OFF: When both of TIMER ON/OFF be set, timer LED is on.

5.3 Emergent switch For some remote control type unit, there is an emergent switch. If the unit is off, press the switch and the indoor unit will run in Auto mode at 24; if the unit is on, press it and then the unit will stop. 5.4 Perform 2 seconds later To avoid the frequent response after receiving signal, the unit will enter the corresponding request 2 seconds later, except for the air gate control. 5.5 Fresh air function When the unit receives the fresh air signal, there is display on LED plate. Only when indoor fan motor has output, the chip can drive the fresh air circuit; if there is no output from indoor motor, fresh air has not output, but the LED still displays. 5.6 Indoor motor alarm If indoor motor can not check the pulse in 10 seconds after being powered on, the system will close the output voltage to indoor motor. After being standby for 30 seconds, electrify the motor again, if in 10 seconds, there is no fan motor pulse, the system will send out alarm, meanwhile, timer LED flashes at 2Hz frequency, 3-second interval. 5.7 Indoor unit number setting If indoor units have not group number and unit number, indoor power LED, run LED, and timer LED

flash together at 2Hz frequency, 3-second interval. When indoor unit receives the set group number signal from outdoor, if the outdoor group number is

different from the indoor previous group No., the previous No. and unit No. will be cancelled, the group No from outdoor will be saved in this indoor EEPROM, meanwhile, indoor power LED, run LED, and timer LED will flash together at 2Hz frequency, 3-second interval, waiting for setting unit number.

In indoor unit has not group number, it will not receive the unit number. When indoor receives the setting unit number signal from address set controler, power LED, run

LED, and timer LED will stop flash at the same time, that shows indoor unit has received the set unit number. If pressing “CHECK” button on adddress set controller, you can check the unit number. The power LED flash times stand for the unit number. For example, the set unit number is 5, the power LED flashes 5 times at 2 Hz frequency, 3-second interval.

If indoor unit receives the lock command from outdoor, the unit number can not be set. When receiving the setting unit number signal, two times of “dudu” sound shows that the unit has refused to be set unit number.

When setting unit number, if there is repeated number, two times of “dudu” shows re-setting unit number.

When setting unit number, avoid setting number towards mutiple indoor units. Thus you can not check if there is repeated number, which will affect the normal communication.

When setting unit number, the time interval is better more than 10 seconds, in order to check the repeated numbers.

When setting unit number, please set the number at a certain order, to avoid the repeated number. The address set controller: emission distance is 1 meter, two sets of 5# batteries, static current is

5uA.

5.8 Indoor communication abnormal In the following cases, indoor unit will alarm: 1) indoor unit can not communicate with the exterior in 3 minutes 2) If indoor unit can not communicate with EEV in 30 seconds 3) If two indoor units have the same unit numbers, both of them will alarm 5.9 Time-shorting function After being powered on, make a jumper for the port “TEST PROGRAM” on PCB, in this case, you will hear “di di di” sound three times from the buzzer. And then the control board CPU will operate at the speed of faster 60 times than before. Take down the jumper, time-shorting function is cancelled. 5.10 Auto restart function In 5 seconds, press SLEEP (SWING) button 10 times contineously, the buzzer sounds 4 times to enter auto-restart state. In 5 seconds, press SLEEP (SWING) button 10 times contineously, the buzzer will sound 2 times to quit the auto restart function. The function will memorize the following states: ON/OFF, MODE, FAN, TEMP., HEALTH, SWING; If there are TIMER or SLEEP functions, when being powered on, TIMER and SLEEP will be cancelled. 5.11 Abnormal mode There is no display on wired controller and remote controller ( buzzer sounds two times). COOL/HEAT, DRY/HEAT, AUTO(COOL)/HEAT, AUTO(HEAT)/COOL, AUTO(HEAT)/DRY---entering earlier is in prior, when the earlier entering mode changes, the other modes can be set, or the unit can not start up or be standby. In abnormal mode, fan motor stops (this malfunction can be resumed automatically). 5.12 Manual defrost (for some outdoor, not available) Press SWING button 8 times, the buzzer will sound 3 times, and then sends defrost signal to outdoor. The outdoor will stop the present operation and begin defrost. 5.13 Water pump and float switch Water pump control: When indoor unit is not in heating mode, the water pump will be powered on to run until indoor unit stop; after indoor unit stops, the water pump will continue running for 5 minutes and then stop. When in heating mode, water pump will not work. If the system checks there is overflow, the below measures will be taken: 1) In cooling, sending stop signal to outdoor 2) In heating, sending stop signal to outdoor 3) In stop mode or Fan mode, not sending any signal 4) If the drainage relay is on, when the pump checks the overflow for contineous 2 minutes, it will send

failure signal. Note: In order to prevent the wrong action resulted from un-steady water level, if the float switch action time is over 1 second, it will adjust the water level is high. 5.14 Sleep operation In sleep mode, indoor motor can run at the set speed, but the set temperature can be changed to keep comfortable. 5.15 Auto mode When entering auto mode for the first time, the actual mode depends on the room temperature (Tr) and the set temperature (Ts). Tr≥Ts, cooling mode Tr＜Ts, heating mode

AU48NFIBIA PCB ports name and functions

-148-

Below we will comment for the functions of some ports and some changes of PCB 0010451530 and 0010451531: 1. Control Board 0010451530 Herein, the control board we are concerned is the board without CPU. Functions for every port are as follows: CN301: port for power supply, connected with CN202 of the power board. CN302: connected to testing board. CN303: connected to the computer serial port through the testing device. CN304: HBUS communication port. CN305: the driving port for relay, connected to CN203 of the power board. CN306: the driving port for IPM, connected to CN105 of the power board. CN307, CN308: port for the heat-emitting fan. No used at present. CN309: port for the main relay and for testing current, connected to CN104 of the power board. CN310: the driving port for electronic expansion valve. CN311: testing port for the radiator temperature. No used at present. CN312: testing port for the coil temperature Tt. CN313: testing port for the defrosting temperature Te. CN314: testing port for the outdoor ambient temperature Ta. CN315: testing port for the suction temperature Ts. CN316: testing port for the discharging temperature Td. CN317: port for the signal of compressor overheat protection initially,but now for low pressure switch. CN318: port for the signal of high/low pressure protection,but now only for high pressure switch.

Control board 1 Control board 2 Control board 3 Totally there are 3 types of control board, because they have different appearance, you will distinguish them much easier. Control board 1 is the earliest edition, because this board is rather big and it will cover the fixing screw which supports the electric control box, also taken into consideration the convenient installation and service, we modified and designed the Control board 2. Control board 2 is the second edition, because there are electric parts on both sides of this board, and

-149-

hard to be installed, we designed the Control board 3. Contro l boa rd 3: the current edition. Now the part number of control PCB is 0010451971

2. Power board 0010451531 There are two types of power board, and they have the same dimensions, but have the different voltage testing parts. That is easy to distinguish. The newly power board adopts the voltage sensor to test the voltage. On the board there is a black square type voltage sensor. The old board adopted the LM331 to test the voltage, which is an inserted part IC with 8 feet. However both the new or old power boards can match any of the control board, but the CPU diagrams are different. 3. Fil ter board 0010451536 Originally, the electric control box has not any filter board. In order to avoid the exterior interference and result in the bad communication, the second edition (current edition) are all added the filter board.

instead of 0010451530. The new control board(0010451971) also can be used as 0010451530,but the connector

"OH" must be shorted.
