DE-ICE OPERATION
Entering de-ice operation(to turn cooling cycle).
1. The micro-computer chip is check the temperature of condensor, After 50 minutes since the units starts on heating mode.
2. If the Temperature is below -4˚C, the De-ice function will start.
3. Now, the unit turned to cooling operation but fan motor is off.
Back to heat mode.
1. On the de-ice operation if the temperature is going over 15˚C.
2. Or 15minutes passed on the de-ice operation.
3. Now the unit turned to heating mode.
Remark: This de-ice operation is always repeat in heating mode when satisfying of the condition to enter the de-ice

PCB DRIVING DESCRIPTION
1. Power Supply Circuit
DC 12V and DC 5V Power source circuit.
Diode D4~D7 : Rectifier Diodes
Condenser CE1 and CE2 : Smoothing circuit components.
DC 12V Power output is made by switching performance of Device IC2 and TRS1.
DC 12V Power is used for Relay and Buzzer driving.
DC 5V is regulated by IC1. It is used for LED display, Sensor, Key and Micom driving.
Regulation of DC12V is performed by PC1 and its voltage feedback signal.
And the others are generally used for noise consumption.
2. Reset Operation Circuit
Micom IC4 is operated by IC5 and its signal. Generally, DC5V is checked at port 27 of IC4.
R5 and CE5 : Parts for determine reset signal timing when the power is ON and OFF.
29
3. Sensor Signal Input Circuit and Option
Port 4 of IC4 is terminal of A/D converter input.
Room temperature is sensing by change of temperature resistance.
The input voltage is determined by ratio between R8 (10.0 KΩ) and Room sensor value.
Relation between temperature and input voltage is as following.

Port 10 of IC1 is a type of temperature display option port.
It is determined by ratio between R11 and R12.
Relation between R1 and Display temperature type is as following.

4. Display drive and Key Input Circuit
Display operation is dynamic scan drive type. It has 1/3 duty cycle.
Scan signal output : Port 21, Port 22, Port 23
TR1~TR6 : Scan signal drive circuit
R1~R7 : LED current limit resistance .(for 6 high current output port 12,13,15,16,17,18)
Port 19, Port 24 of IC4 : Key signal input by scan.
Oscillatory frequency is 8MHz. It is made up resonator oscillatory frequency.
Oscillatory wave is sine wave shape.
The remote control signal input is detacted at port 5 of IC4.
CE6 and CC8 : Noise protection parts
31
5. Relay and Buzzer drive Circuit
Port 6,7,9 of IC4 : Relay ON and OFF drive signal output.
IC3 : Relay ON and OFF drive device.
Fan Motor ON/OFF and Speed control : RL2, RL3, RL4
Compressor ON/OFF control : RL1.
Swing Motor ON/OFF control : RL5
Buzzer is operated by Port 26 of IC4. Operative frequency is 2 KHz, 1/2 duty pulse.
