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.

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. Compressor Fan speed Cooling zone ON "UL" Dehumidifying zone ON "D" Circulating zone OFF "D" or OFF 2-3 Fan only operation The indoor fan motor always turns on. 3. Fan speed Fan speeds are given by the indoor fan motor, “H”, “M”, “L” and “UL”, which are available in the following operation mode. 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. Table H-2 FAN Switch HIGH LOW SOFT COOL M L UL FAN ONLY M L UL 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. 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”.

Above 28˚C 26˚C to 28˚C 24˚C to 26˚C Below 24˚C 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.
