File Explanation:
The VAV damper is controlled by a set of nested "if-then-else"
statements. The nested "if-then-else" statements prioritize the control
modes as follows:
• The FSCS overrides: OPEN-CLOSE
• Automatic Smoke Control
• HVAC control
The HVAC control is performed by setting the value of
DefaultDmprPosn.
In this example, setting the output to 0 will open the damper, and setting
the damper to 1 will close the damper.
