According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room tem-
perature is too cold.
During automatic operation, if the room temperature changes and
remains 1.5 °C or more above the set temperature for 3 minutes, the
air conditioner switches to cooling mode. In the same way, if the room
temperature remains 1.5°C or more below the set temperature for 3
minutes, the air conditioner switches to heating mode.
