Dehumidifying operation will be resumed when room temperature restores to over At dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the same as that of cooling mode At dehumidifying mode, the action of fans of indoor is the same as that of air-only mode. 8.8 Heating mode 8.8. Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode. 4-way valve must delay minutes compared with compressor if the compressor changed into non-heating mode or turned off. 4-way valve doesn't delay in dehumidifying mode Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except for the defrosting mode or the end of defrost Action of compressor and outdoor fan motor at heating mode: compressor must run for 7 minutes after starting and then judge temperature.

Fan speed is high Fan speed is mid Fan speed is low Breeze TH DEFROST TM DEFROST TL DEFROST Meet only if it is Breeze Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor fan with the compressor still running. Add up to 90 minutes Defrosting time If the temp. difference condition is satisfied for less than 40 minutes, this can be regarded as severe frosting. The defrosting time is 0 minutes. If the temp. difference condition is satisfied for more than 40 minutes, the defrosting time is 6 minutes. If the temp. difference condition is satisfied out of 40 minutes, generally the defrosting time is 6 minutes, after three continuous 6-minute defrost, the fourth should be 0 minutes defrost. The circulation is as following: 7.5-minute defrost 7.5-minute defrost 7.5-minute defrost 0-minute defrost Ending condition of defrosting If one of following conditions is satisfied, end the defrost and turn into heating mode: 30

The air conditioner automatically selects one of the following operation modes: cooling, heating or fan only according to the temp. difference between room temp. (TA) and set temp. (TS). TA TS TA TS> - TA-TS + Operation mode Cooling Fan-only TA-TS<- Heating (air-only for cooling only type) 8.0. The indoor fan blows automatically in corresponding selected mode The motion of indoor fan s blade should accord with the selected operation mode One mode should be carried out for at least 5 minutes once selected. If the compressor cannot start for 5 minutes, reselect the operation mode according to the room temp. and set temp., or reselect when the set temp. varies. 8. Forced cooling function 8.. Select forced cooling function with the forced cooling button or the switch. 8.. The compressor is unconditionally turned on, after 30 minutes cooling operation whose fan mode is set as low, the A/C operates at the DRY mode with a set temp. of All protections of remote control cooling are available at forced cooling operation. 8. Forced Auto function Select forced auto function with the forced auto button or the switch. In forced auto status the A/C operates at remote control mode with a set temp. of Timer Function 8.4 Sleep mode 8.4. The sleep function is available at cooling, heating or auto mode. 3

34 8.4. Cooling: The set temperature rise per hour. Two hours later, the set temperature will maintain as a constant and the fan speed is kept at low speed. The total time is 7 hours, after 7 hours the unit stops Heating: The set temperature decrease 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). The total time is 7 hours, after 7 hours the unit stops Auto: The economic running function operates in accordance with selected running mode by auto mode. The total time is 7 hours, after 7 hours the unit stops. 8.5 Auto restart function In case of a sudden power failure, this function automatically sets the unit to previous settings before the power failure when power returns. 8.6 PLASMA ( optional): Starts with indoor fan. Note: Plasma and Anion can be use together. 8.7 Anion (optional) Starts with indoor fan. Note: Plasma and Anion can be use together. 33

DE FROST indicator (F or Cooling & H eating mo dels only) This indicator illuminates when the air conditioner starts defrosting automatically or when the warm air control feature is activated in heating oper ation. TEMPERATURE indicator Displays the temperature settings when the air conditioner is operational. OPERATION in dicator This indicator fl ashe s after power is on and illuminate s when the unit is in operation. TIMER indicator This indicator il luminates when TIMER is set ON/OFF. 9. For all heat pump model Failure phenomenon Operation lamp Timer lamp Indoor fan speed has been out of control for over minute X Indoor room temp. or evaporator sensor is open circuit or short circuit On Over current protection of the compressor occurs 4 times X EEROM error On No over-zero signal r Extinguish Flash at 5Hz 35

37 9.3 Diagnostic Chart 9.3. After energizing, no indicator is lighted and the air conditioner can t be operated. After energizing, the air conditioner can t be operated Check if AC0V power supply outputs to Indoor PCB. Yes Check if AC0V exists at the primary coil of transformer. Yes No Indoor PCB is defective Check if AC4.5V exists at the secondary coil of transformer. No Take off the secondary plug of transformer, and then check if AC4.5V exists at the secondary coil of transformer. Yes Yes No The transformer is defective. Indoor PCB is defective 9.3. Resetting phenomenon often occurs during operation. (That is automatically entering to the status when power is on.) The reason is that the instantaneous voltage of main chip is less than 4.5V. Check according to the following procedure: Resetting phenomenon often occurs during operation. Yes After changing Indoor PCB, check if the failure releases. No Yes After changing indoor fan motor, check if the failure releases. Indoor PCB is defective No Power supply circuit has problems. 36

38 9.3.3 Failure phenomenon Failure phenomenon Operation lamp Timer lamp Indoor fan speed has been out of control for over minute X Indoor room temp. or evaporator sensor is open circuit or short circuit On Over current protection of the compressor occurs 4 times X EEROM error On No over-zero signal r Extinguish Flash at 5Hz Operation lamp flashes and Timer lamp off. Is connector connection good? Yes No Is voltage being applied to the fan motor? Repair the connector Yes Fan motor is defective No Indoor PCB is defective Operation lamp flashes and Timer lamp on. Is connection to connector good? Yes Replace the sensor No Repair connector Operation lamp off and Timer lamp flashes Operation lamp off and Timer lamp flashes After changing the main control board, check if the failure releases. No The voltage of power supply is too low (less than 87V)? Yes Yes Indoor PCB is defective Yes Power supply fault No Outdoor unit fault (such as the compressor) Operation lamp on and Timer lamp flashes EEROM error, indoor PCB is defective Operation lamp flashes, Timer lamp flashes. This is alarm signal when the main chip can t detect over-zero signal. When such failure occurs, the main control board must have fault. 37
