■ According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room
temperature is too cold.
■ During automatic operation, if the room temperature changes and
remains 2 °C or more above the set temperature for 15 minutes, the
air conditioner switches to cooling mode. In the same way, if the room
temperature remains 2 °C or more below the set temperature for 15
minutes, the air conditioner switches to heating mode.

degrees cooler than the set room temperature once the temperature
is reached (automatic energy-saving operation).
