States 1 & 3 : Compressor ON State 2 : Compressor OFF
2. Operation modes 2-1 COOL operation The compressor turns on or off, at the thermostat lines C3 and C4. The outdoor fan motor is also controlled with the compressor.

Figure H-1 1-2 DRY operation In the "DRY" mode, the thermostat circuit is controlled by three thermostat lines (D1 thru D3). 2-2
Figure H-3 DRY operation On the switch on, the compressor always starts to operate for 2 minutes with fan speed "D" (slower than "UL"). The microcomputer measures the room temperature 2 minutes after this first compressor operation. This room temperature is set as the preset temperature automatically. The preset temperature ranges from 18°C to 32°C. When the room temperature is below 18°C, the preset temperature is set to 18°C, and when the room temperature is over 32°C, the preset temperature is set to 32°C Dry operation is divided into three zones (Cooling zone, Dehumidifying zone and Circulating zone) by thermostat lines (D1 to D3), and the compressor and the fan motor are controlled in each zone as shown in Table H-1.

Fan only operation The indoor fan motor always turns on.

7. Timer 7-1 24-HOUR PROGRAMMABLE ON/OFF TIMER ON-TIMER or OFF-TIMER can be independently programmed. When the unit operates during one hour after the OFF-time is set, thermostat setting is automatically shifted (+1°C in cool operation and dry operation, -3°C in heat operation, but, 16°C set temperature at the lowest). When the ON-timer is set in heat operation and cool operation, operation starts before 0 to 30 minutes(depends on the room temperature) so that preset temperature is obtaind at set time. 7-2 ONE-HOUR TIMER When ONE-HOUR timer is set, the unit turns off automatically after one hour. The one hour timer operation has priority over other time operation, such as the TIMER ON and TIMER OFF. If the ONE-HOUR TIMER button is pressed again during operation, the unit will operate additionally for another one hour. 8. Automatic air conditioning When automatic air conditioning is selected, the operation mode and preset temperature are set automatically according to the room temperature on starting operation. Table H-3

4. Anti-sweating When the operation continues 30 minutes in cooling zone or dehumidifying zone during dry operation or in continuous compressor operation during cool operation, the fan speed of indoor fan motor shifts up, from "UL" to "L" or from "D" to "UL". 5. Freeze preventive When the indoor pipe temperature falls below -1°C during cool operation or dry operation, the compressor is stopped. 6. Test run If the "TEST RUN" button in the unit is pushed during suspension of operation, cool test operation starts. At this time, the fan speed is set to "AUTO". If this button is pushed during operation, the test operation starts in current operation mode. The operation LED (red) flickers during test run. During cool operation and heat operation, the compressor is kept on but in dry operation it is set in the dehumidifying zone. In fan only mode the indoor fan motor runs continuously.
9. Automatic fan speed When the automatic fan speed is selected in cool or heat operation, the fan speed is automatically changed by the thermostat lines C1 to C3 in cool operation and H1 to H4 in heat operation.

13.Diagnosis procedure When indoor fan motor is out of order or compressor lock occurs, the compressor, inddor fan motor, outdoor fan motor, and louver are all stopped and the operation LED(red) turns on or off syncronously with the timimg of the timer LED. When the thermistor for room temperature or pipe temperature is open or short state, the operation LED turns on or off syncronously with the timing of the timer LED by pushing continously for more than three seconds both "TEST" button and "AUX." button. 1sec.

14.Test mode 14-1 TEST 1 (For control circuit operation checking) Make terminals 1 and 2 of connector CN4 short-circuited and supply power. The timer's periods become shorter i.e. a 3 minute cycle is carried out in 3 seconds, except for ; The operation LED flicker's period in Test run The protector timer The defrost timer

14-2 TEST 2 (For output of each operation checking) Test mode is for checking output of each operation. Keep pushing both the buttons, "AUX." and "TEST RUN", and supply the power, the system will go to the test 2 mode. In this mode, the output of operation is switched by the "TEST RUN" button in the unit or the "OI" button in the remote controller. Use the "AUX." button to back to step 1.
