5. Outdoor Fan Control
5-1. Fan mode
These outdoor units utilize a DC fan motor that can be controlled in a maximum of 15 steps (15 modes).
However, fan modes 14 and 15 can only be used if high static pressure mode has been set.
* For information concerning EEPROM settings, refer to the field application functions.
* For the sake of protecting temperature of the electrical parts, the minimum values of the fan mode may sometimes
increase in accordance with the ambient temperature or the amount of secondary current.
The following table shows the maximum and minimum fan mode and fan forced mode for each unit.
