When the unit stops operation, it returns to original factory settings. It will also display the error codes when malfunction or protection happen. Frequency indicator This indicator appears only when the compressor is in operation and indicates the current operating frequency. Run indicator Flash at 0. 5Hz when the unit is standby. Auto indicator This indicator illuminates when the air conditioner is in AUTO operation. Ion indicator Illuminate when Ionizer/Plasma function is activated. LED display control function. Pressing "LED display" button on remote controller will turn off all displays on indoor unit, while pressing once again, all displays will resume. ENG 7. 3 OUTDOOR UNIT'S DIGITAL DISPLAY TUBE frequency. · In defrosting mode, The LED displays "dF" · In compressor pre-heating, The LED displays "1 1" · In protection or malfunction, the LEC displays error code or protection code. 0 There is a digital display tube in outdoor PCB. Digital display tube display function · In standby , The LED displays the number of indoor units. · In compressor operation, the LED display the 7- PCB EXPLANATION 7. 4 OUTDOOR UNIT POINT CHECk FUNCTION There is a check switch in outdoor PCB. When Indoor Fan Speed is too high(higher than High Fan+300RPM)or too low(lower than 400RPM), the unit stops and LED displays failure information and can't return to normal operation automatically. If there is no Cross Zero signals in 4 minutes, the unit stops and LED displays failure information and can't return to normal operation automatically. -Current protection: When the current is more than `X' A, the compressor stops. (X is 7A for 14K 1x unit, is 14A for 18K 1x unit, is 13. 5A for 1 1x3 unit, is 15A for 7K 1x3 unit, is 16A for 7K 1x4 unit and is 1. 5A for 36K 1x4 unit. ) -Outdoor condenser high temperature protection: Under cooling mode, if T3>65 for 3 minutes, the compressor will stop. When T3<5, the protection is not valid. -Pressure protection (just be available for 7K and 36K 1x4 unit): If low pressure is lower 0. 03MPa, the compressor will stop and when low pressure is higher than 0. 10MPa, the compressor will restart. If high pressure is higher than 3. 3MPa, 3 ENG 7- PCB EXPLANATION the compressor will stop and when high pressure is lower than . 4MPa, the compressor will restart. -Compressor pre-heating function: When the outdoor temperature is lower than 3 and the compressor stops operation for more than 3 hours, or the outdoor temperature is lower than 3 and the power is just put on, the compressor enters into pre-heating condition. is more than 5 or user operate it, pre-heating condition will finish. 7. 6 FAN-ONLY MODE Fan speed is high/mid/low/ Auto 7. 7 COOLING MODE -Indoor fan keeps running, fan speed can be set in high/mid/low/ Auto: -Auto fan at cooling mode: (T=Indoor Temp. -Setting Temp. ) Condition Room temp. up T<1. 5 1. 5<T<4 T>4 Room temp. [. . . ] -Cooling: The set temperature rise 1ºC per hour. Two hours later, the set temperature will maintain as a constant and the fan speed is kept at low speed. -Heating: The set temperature decrease 1ºC per hour. Two hours later, the set temperature will maintain as a constant and the air circulation is kept at low speed (Cold air proof function takes precedence over all). [. . . ]
