Auto speed fan mode is also offered in heating mode applications; it will not have any
effect on dehumidification. It will strictly be used for noise comfort issues.
Auto Speed Fan Mode operation for sequences 2 and 3 is dependent on Auto Fan
parameter. When Auto Fan is set to:
 AS (Default) = Auto Speed during occupied periods. Fan is always on during
occupied periods. Low, medium and high speeds operate on temperature offset
from set point.
 AS AD = Auto Speed / Auto Demand during occupied periods.
o Medium and high speeds operate on temperature offset from set point.
Low speed operates on demand and will shut down when no demand
is present.
