Configuration menu to set the available Fan Mode
options. Use the FAN key to select the desired Fan
Mode option.
When selection option

is
chosen in the Fan Menu parameter, the fan operates
as shown in Figure 19. When selection option

is chosen in the Fan Menu
parameter, the fan operates at only the low and high
settings, ignoring the medium setting (Figure 19). This
operation applies to the occupied mode when the fan is
