8-2-4. Automatic Operation

(1)As shown in Fig. 8-2-9, the operation mode (COOL, DRY, HEAT) is selected according to the outside temperature and room temperature when the operation has started.

The operation in Fan mode continues until an operation mode is selected.

If the room temperature is 20°C or higher when “AUTO” operation started within 2 hours after “HEAT” operation had stopped, select an opera- tion mode after Fan operation of ultra low fan.

In AUTO operation, the set temperature of each operation can be corrected by the remote controller in the range of 17 to 30°C.

(2)After selecting the operation mode (COOL, DRY, HEAT), select an operation mode again when a status that the compressor was turned off by the room temperature or outside air temperature continues for 15 minutes.

(3)Powerful Cool mode control

When the outside temperature is above 32°C and indoor temperature is above 28°C, select Cool mode control. In Cool mode, the air flow louver directs downward. When the room tem- perature gains access to the set temperature, it becomes cool memory position.
