Automatic operation
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 2 °C, 4 °F 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, 4 °F or more below the set tempera-
ture for 15 minutes, the air conditioner switches to heating mode.

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

setting.
In the following cases, the actual fan speed generated by the unit
will differ from the speed shown the remote controller display.
1. While the display is showing “STAND BY” or “DEFROST”.
2. When the temperature of the heat exchanger is low in the heat-
ing mode. (e.g. immediately after heating operation starts)
3. In HEAT mode, when room temperature is higher than the tem-
perature setting.
4. When the unit is in DRY mode.
1. While the display is showing “STAND BY” or “DEFROST”.
