Automatic operation (Single set point)
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 1.5 °C or more above the set temperature for 3 minutes, the
air conditioner switches to cool 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 heat mode.

Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few
degrees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).
