2.COOL MODE : The unit operates according to the difference between the setting and room temperature. (18°C~30°C)
3.HEAT MODE : The unit operates according to the difference between the setting and room temperature.(16°C~30°C)
*Prevention against cold wind : In order to prevent the cool air from flowing out at the heat mode, the indoor fan does not operate or operates very slowly in the following cases. At this time, the indoor heat exchanger will be preheating.
-For 3~5 minutes after the initial operation
-For deicing operation
-The operation of an indoor fan in accordance with the temperature of an indoor heat exchanger
