Variable Speed Fan Levels
In the Variable Speed Fan Level table set the speed in percentages by level.
This function requires an Analog Output card.

Several kinds of speed controllers are available, such as TRIAC Control, and Variable Frequency Three
Phase drives.

(refer to Analog Output, page 110), define at least one output as a
variable speed fan.
2. In

3. In
Device Setting > V. Speed Fan Levels
, define the fans' working percentages.
