PCB function manual and operation methodPCB function manual and operation method

Basic functions (the centigrade is used in the following function manual. If there will be Fahrenheit degree,that willbe Tf=TcX1.8+32).

Function Manual

1. Temperature Parameters Indoor preset temperature (Tpreset)

Indoor ambient temperature (Tamb.)

2. Basic Functions Once energized, the compressor shall never be restarted except 3-min interval at least. For the first energization, if the

unit with memory function is off before power failure, the compressor can be restarted without 3-min delay. But if the unit

is on before power failure, the compressor shall be restarted with 3-min delay. Once started, the compressor won’t stop

within 6 min with the change of room temp.

1 Cooling mode

Cooling conditions and process When Tamb. ≥ Tpreset+1 , the unit will run in cooling mode. In this case, the compressor and the outdoor fan run and

the indoor fan runs at setting speed.

When Tamb. ≤ Tpreset-1 , the compressor and the outdoor fan will stop while the indoor fan will run at setting speed.

When Tpreset-1 Tamb. Tpreset+1 , the unit will maintain its previous running state.

In this mode, the four-way valve is de-energizing, and setting temperature range is 16 30 . Running and cooling

marks and setting temperature are displayed.

Protection

Antifreezing potection If it is detected that the system is in antifreezing protection, the compressor and the outdoor fan will stop running, and

the indoor fan will run at setting speed. If the antifreezing protection is released and the compressor has been stopped

for 3 min, the unit will resume its previous running state.

Overcurrent Protection(applicable to some models) If it is detected that the system amperage exceeds the specified value in 3s successively, the outdoor unit will enter into

the state that only the fan is running. If the overcurrent protection is released, the complete unit will resume its previous

running state. If 6 times of protection successively occur (if the compressor has been running over 6mins continuously,

the protection times will be cleared), the complete unit will stop except the indoor fan is running. In this case, the unit can

be normally restarted only after turning off the unit by remote controller. The nixie tube displays error code E5 and the

running LED blinks (Blink 5 times and pauses 3 s,Blinking interval is 0.5 s).

2 Dry Mode

Dry Conditions and Process When Tamb. Tpreset+2 , the unit will run in dry and cooling mode. In this case the compressor and outdoor fan will

run and the indoor fan will run at low speed.

When Tpreset-2 ≤ Tamb. ≤ Tpreset+2 , the unit will run in dry mode. In this case, the indoor fan will run at low

speed, and the compressor and the outdoor fan will be stopped in 6 min. After 4 min, the compressor and the outdoor

fan will be restarted. Dry process is cycled as the above.

When Tamb. Tpreset-2 , the compressor and the outdoor fan will stop working and the indoor fan will run at low

speed.

In this mode, the four-way valve is de-energizing, and setting temperature range is 16 30 . Running and cooling

marks and setting temperature are displayed.

Protection

Antifreezing potection If antifreezing protection of the system is detected in dry and cooling mode, the compressor and the outdoor fan will stop

running and the indoor fan will run at low speed. When the antifreezing protection is released and the compressor has

been stopped for 3 min, the complete unit will resume its previous running state. Upon the condition that the compressor

runs for 6 min and stops for 4 min is met and antifreezing protection is detected, the compressor and the outdoor fan will

stop running and the indoor fan will run at low speed. When the antifreezing protection is released and the compressor

has been stopped for 4 min, the complete unit will resume its previous running state.

Other protection Other protections are the same as those in cooling mode.

3 Heating mode (cooling only unit is not available)

Heating conditions and process When Tamb. ≤ Tpreset+2 , the unit will run in heating mode. In this case, the four-way valve, the compressor and the

outdoor fan will run simultaneously. The indoor fan will delay at most 2mins to run.

When Tamb≥ Tpreset+4 , the compressor and the outdoor fan will stop while the four-way valve will keep energizing

temperature resumes to normal condition, the outdoor fan will resume running.

Noise Silencing Protection If the unit is stopped by pressing ON/OFF or during switchover of modes, the reversing valve will be stopped after 2 min.

Overcurrent Protection

This protection is the same as that in cooling mode (but indoor fan will blow residual heat).

4 Fan mode In this mode, indoor fan runs at setting speed, and the compressor, the outdoor fan, the four-way valve and the electric

heating tube (will) stop running. In this mode, temperature setting range is 16 30 . Displayer displays running marks

and the setting temperature.

5 Auto Mode In this mode, the air conditioner will automatically select its running mode (cooling, heating or fan) with the change of

ambient temperature. The displayer will display the running marks, actual running mode mark and setting temperature.

There is 30s delay protection for mode switching. Protection functions are the same as those in any other mode.

3 Other Control 1 Timer function

The mainboard combines general timer and clock timer functions. Timer functions are selected by equipping remote

controller with different functions.

General Timer Timer ON can be set under off state of unit. If timer ON reaches, the controller will run under previous setting mode.

Timing interval is 0.5hr and the setting range is 0.5-24hr.

Timer OFF can be set under on state of unit. If timer OFF reaches, the unit is turned off. Timing interval is 0.5hr within

the range of 0.5-24hr.

Clock Timer If timer on is set under running state of unit, the system will continue running. If timer on is set under off state of unit, the

system will run in presetting mode when timer on reaches.

If timer off is set under off state of unit, the system will keep standby state. If timer off is set under on state of unit, the

system will stop running when timer off reaches.

Timer Change If the system is under timer state, the unit can be turned on/off by ON/OFF button of remote controller. Timing can also

be reset and then the system runs according to the final setting.

If timer on and timer off is set at the same time under running state of system, the system will keep current running state

till timer off reaches and then it will stop running.

If timer on and timer off are set at the same time under off state of system, the system will keep stopping till timer on

reaches and then it will start running.

In the future, the system will run in presetting mode when timer on reaches and stop when timer off reaches every day. If

timer on and timer off have the same setting, timer off is prevails.

2 Auto Button If press this button, the system will run in auto mode, and the indoor fan motor will run at auto speed; meanwhile, the

swing motor will be running. Repress this button to turn off the unit.

3 Buzzer

Upon energization or operation, the buzzer will give out a beep.

4 Sleep Function

The mode can provide different selection of the setting temperature curve for sleeping.

5 Turbo Function

This function can be set in cooling or heating mode.

6 Dry Function

This function can be set in cooling or dry mode.

7 Automatic Control of Fan Speed In this mode, the indoor fan will automatically select high, medium or low speed with the change of ambient temperature.

8 Up & Down Swing After energization, up & Down swing motor will rotate guide louver anticlockwise to position 0 to close air outlet. After

turning on the unit, if swing function has not been set, up & down guide louver will clockwise turn to position D in heating

mode, or clockwise turn to level position L in other modes.

If the unit is turned on with swing function setting, the guide louver will swing between W and D.

There are 7 kinds of swing states of guide louver: There are position L, A, B, C, D, and it swings

and stops between L and D ( angle between L and D is equiangular).

Upon stop of unit, the guide louver will close to position O. Swing action is valid only when swing

command is set and indoor fan is running.

Note: If the position is set between L and B, A and C or B and D by remote controller, the guide

louver will swing between W and D.

9 Display

Running mark and Mode mark Upon energization, the unit will display all marks. Under standby state, running indicating mark is displayed in red. If the

unit is started by remote controller, running indicating mark gives off light; meanwhile, the current setting running mode

mark will be displayed(mode LED: cooling, heating and dry mode). If the light button is turned off, all marks display will

be closed.

Dual-8 Display After starting the unit for the first time, the nixie tube will default to display the current preset temperature (16-30 ).

When displaying setting temperature signal is received, the nixie tube will display setting temp. If displaying ambient

temperature signal is received, the nixie tube will display current indoor ambient temperature. If other states are set by

remote controller, the display will keep previous. If remote controller receives valid signal during displaying ambient

temperature, ambient temperature will be displayed after setting temperature is displayed for 5s. F1 is displayed for

ambient temperature sensor malfunction, F2 for tube temp sensor malfunction of indoor unit and C5 for jumper cap has

malfunction.

Some models: The remote controller will display current setting temp when this display is set. The controller will display

ambient temp for 5s and then setting temp only when indoor ambient temp displaying state is switched from other

displaying states by remote controller

10 Locked protection to PG motor When starting the fan, if motor’s rotational speed is slow for a period of time, the unit will display Locked and stop

running to avoid auto protection for motor. If the unit is on currently, error code H6 will be displayed by the Dual-8

Display. If the unit is off currently, this locked malfunction information won’t be displayed.

11 Power-off memory Memory content includes mode, up&down swing, light, setting temp and setting fan speed.

Upon power failure, the unit after power recovery will automatically start to run according to memory content. The

system, last remote-control command without timer setting, will memorize the last remote-control signal and run

according to it. If the last remote-control command has general timer function and the system is de-energized before

setting time, the system will memorize the last timer function in remote controller command after re-energization and

time will be recalculated. If there is function in the last remote controller command but setting time has reached, the

system will act as timer on/off setting before de-energization. After re-energization, the system memorizes the running

states before power failure without timer action. Clock timer can not be memorized.

4 Special functions 1 Health function

When the indoor fan motor is running, the Health function is set by pressing remote controller (If there is no Health

button on the remote controller, the Health function opening is defaulted).

2 I Feel function If the remote controller receives the I Feel order, the controller will work at the ambient temperature value which is sent

by remote controller (Except the defrosting and anti-cool wind, which still adopts the sampling value of AC itself ambient

temperature sensor), the remote controller will send ambient temperature value to controller at intervals. If the controller

hasn’t received the ambient temperature value from the remote controller for long time, then it will run accroding to the

current ambient temperature of AC. If the function has not been set, the ambient temperature will adopt the sensor

sampling value of AC itself. If power off happens, this function will not be memorized.

3 Temperature sensor malfunction detection

F1 is displayed when the indoor ambient sensor malfunction is detected and F2 is displayed when the indoor tube sensor

malfunction.

Measure insulation resistanceto ground to see if there is anyleakage.

The circuit or the part of the airconditioner has malfunction.They heat and break the insula-tion and lead to short circuit orcreepage. Measure the insula-tion resistance or eliminate themalfunction one by one. If thebreaker itself has malfunction,then replace the breaker.

The transformer connection isloose or has bad contact or thetransformer has malfunction.

Fasten the wiring; measure theoutput voltage of the trans-former , if it is incorrect, changethe transformer.

No power Check power supply circuit.

Power plug is not well plugged inand poor connection.

Check if the plug is properlyplugged in and make the loosecontact firm.

Fuse of controller burnt out

The air condi-tioner does notreact after it ispowered ( afterthe plug isinserted, thebuzzer does notsound and theremote startuphas noresponse)

Remote controller malfunction

Receiver loose or poor connection

Receiver is broken

Change controller fuse

Controller is broken Check remote controller

Remote controller is short of power Change batteries

First, press the manual switchbutton AUTO,i f there is noresponse,check based on theabove methods. If it runs nor-mally after pressing the button,check again whether the instal-lation position and the connec-tion wire of the reception headis correct. If it is correct,then re-place the receiver or the remotecontroller.

Power voltage is too lowCheck the voltage. If it is lower than 10% ofthe rated voltage, check the cause, improvethe power supply condition and add the sta-bilized voltage power supply.

The breaker trips at once when itis set to “ON”.

The breaker trips in few minuteswhen it is set to “ON”.
