Configuring Automatic Fan Speed
Use the Fan Menu parameter in the Installer
Configuration menu to set the available Fan Mode
options. Use the FAN key to select the desired Fan
Mode option.
When selection option (2): Low-Med-High-Auto is
chosen in the Fan Menu parameter, the fan operates
as shown in Figure 21. When selection option
(3): Low-High-Auto is chosen in the Fan Menu
parameter, the fan operates at only the low and high
settings, ignoring the medium setting (Figure 21). This
operation applies to the occupied mode when the fan is
set to Auto.
