FILE. SVM-09030 7-2. Outline of Air Conditioner Control This is a fixed capacity type air conditioner, which uses a AC motor for an indoor fan. The AC motor drive circuit is mounted in the indoor unit. And electrical parts which operate the compressor and the outdoor fan motor, are mounted in the outdoor unit. The air conditioner is mainly controlled by the indoor unit controller. The controller operates the indoor fan motor based upon commands transmitted by the remote control and transfers the operation commands to the outdoor unit. The outdoor unit receives operation commands from the indoor unit, and operates the outdoor fan motor and the compressor. (1) Role of indoor unit controller The indoor unit controller receives the operation commands from the remote control and executes them. Temperature measurement at the air inlet of the indoor heat exchanger by the indoor temperature sensor Temperature measurement of the indoor heat exchanger by the heat exchanger sensor Louver motor control Indoor fan motor operation control LED display control Transferring of operation commands to the outdoor unit Receiving of information of the operation status and judging of the information or indication of error (2) Role of outdoor unit controller The outdoor unit controller receives the operation commands from the indoor controller and executes them. Compressor operation control Operation control of outdoor fan motor Operations according to the commands from the indoor unit Table 7-2-3 Indoor fan and air flow rate Turning off the compressor and outdoor fan when the outdoor unit receives the shutdown command Defrost control in heating operation (Temperature measurement by the Indoor heat exchanger, control the four-way valve and outdoor fan motor control) 7-2-1. Louver control (1) Vertical air flow louver Position of veritcal air flow louver is automatically controlled according to the operation mode. Besides, position of vertical air flow louver can be arbitrarily set by pressing [FIX] button. The louver position which is set by [FIX] button is stored in the microcomputer, and the louver is automatically set at the stored position for the next operation. (2) Swing If [SWING] button is pressed when the indoor unit is in operation, the vertical air flow louver starts swinging. When [SWING] button is pressed, it stops swinging. 7-2-2. Indoor Fan Control The operation controls the fan speed at indoor unit side. The indoor fan (cross flow fan) is operated by the phase control induction motor. The fan rotates in 5 stages in MANUAL mode, and in 5 stages in AUTO mode, respectively. (Table 7-2-3) 1) When setting the fan speed to L, L+,M, M+ or H on the remote controller, the operation is performed with the constant speed shown in Table 7-2-1 and Table 7-2-2 Table (7-2-1) Cooling Table (7-2-2) Heating Indication L L+ M M+ H Fan speed Low (L + M) / 2 Med (M + H) / 2 High Indication L L+ M M+ H Fan speed Low (L + M) / 2 Med (M + H) / 2 High 2) When setting the fan speed to AUTO on the remote controller, revolution of the fan motor is controlled to the fan speed level show in Table 7-2-3 according to the setup temperature, room temperature, and heat exchanger temperature.

Self-Cleaning Operation Unit now performing cooling or dry operation Press STOP button Only timer indicator lights, and Self-Cleaning operation starts Time set now elapses Operation stops During Self-Cleaning operations: The louver opens slightly. The indoor fan operates continuously at a speed of SL rpm. 1. Purpose The Self-Cleaning operation is to minimize the growth of mold, bacteria etc. by running the fan and drying so as to keep the inside of the air conditioner clean. Self-Cleaning operation When the cooling or dry operation shuts down, the unit automatically starts the Self-Cleaning operation which is then performed for the specified period based on duration of the operation which was performed prior to the shutdown, after which the Self-Cleaning operation stops. (The Self-Cleaning operation is not performed after a heating operation.) 2. Operation 1) When the stop signal from the remote controller or timer-off function is received, only the timer indicator light. 2) The period of the Self-Cleaning operation is determined by the duration of the operation performed prior to the reception of the stop code. 3) After the Self-Cleaning operation has been performed for the specified period, the unit stops operation. Self-Cleaning operation times Cooling: Auto (cooling) Dry Operation time Up to 10 minutes 10 minutes or longer Self-Cleaning operation time No Self-Cleaning operation performed (0 minutes) 20 mins.

FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK. CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE DAMAGED. CHECK THE EARTH WIRE THAT IT IS T BROKEN OR DISCONNECTED BEFORE INSTALLATION. DO T INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS. FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION. TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M) FROM HEAT SOURCES SUCH AS RADIATORS, HEATORS, FURNACE, STOVES, ETC. WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ATHER PLACE AGAIN, BE VERY CAREFUL T TO GET THE SPECIFIED REFRIGERANT (R22) WITH ANY OTHER GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN THE REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABRMALLY HIGH AND IT RESULTINGLY CAUSES BURST OF THE PIPE AND INJURIES ON PERSONS. IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION WORK, IMMEDIATELY LET FRESH AIR INTO THE ROOM.
