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.
Ŷ
During automatic operation, if the room temperature changes and
remains 1.5 °C (3 °F) 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 (3 °F) 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).

<Auto operation (dual set point) mode>
When the operation mode is set to the Auto (dual set point) mode, two
preset temperatures (one each for cooling and heating) can be set.
Depending on the room temperature, indoor unit will automatically
operate in either the Cool or Heat mode and keep the room temperature
within the preset range.
