File Explanation:
This program controls the state of the Supply fan, Return fan, Outside
Air damper, Exhaust Air damper, and Return Air damper for AHU1.
Each fan or damper is controlled by it’s own set of nested “if-then-else”
statements. The nested “if-then-else” statements prioritize the control
modes as follows:
• The FSCS overrides: ON-OFF, OPEN-CLOSE
• Automatic Smoke Control
• HVAC control
The HVAC control is performed by setting the default values for each
fan or damper: Default.Sfan, Default.Rfan, DefaultDmpr.OA,
DefaultDmpr.EA, DefaultDmpr.RA.
This program also calls the OVR_Check function.
