Automatic operation
■
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.

■
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).

2. When the temperature of the heat exchanger is low in the
heating mode.
(e.g. immediately after heating operation starts)
3. In HEAT mode, when room temperature is higher than the
temperature setting.
4. When the unit is in DRY mode.
