• Preset cooling temperature is higher than preset heating temperature.
• The minimum temperature difference requirement between cooling and

connected) is met.
* If preset temperatures are set in a way that does not meet the minimum
temperature difference requirement, both preset temperatures will
automatically be changed within the allowable setting ranges.

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