I According to a set temperature, cooling operation starts if the room tem-
perature is too hot and heating operation starts if the room temperature
is too cold.
I During automatic operation, if the room temperature changes and re-
mains 1.5 °C or more above the set temperature for 3 minutes, the air
conditioner switches to cooling mode. In the same way, if the room tem-
perature remains 1.5 °C or more below the set temperature for 3 min-
utes, the air conditioner switches to heating mode.
Cooling mode
3 minutes (switches
from cooling to heating )
I 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).

Note:
G The number of available fan speeds depends on the type of unit connected.
Note also that some units do not provide an "Auto" setting.
G 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 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.

2. Immediately after starting heater mode (while the system is waiting for
the mode change to take effect).
3. In heat mode, when room temperature is higher than the temperature set-
ting.
