Creating Exception Graphics for Unique Equipment

Problem

Most VAVs follow the same template, but one room has a custom fan coil unit instead—need a different graphic for it.

Solution

1. Identify the Exception Equipment

• Note which equipment doesn't fit the standard template (e.g., custom FCU in Room 340)
• Document its control points and operational differences

2. Create an Exception Graphic

• In Graphics Manager, create a new graphic specifically for this equipment
• Example: "Room_340_FCU_Custom" instead of generic "VAV" template
• Design controls based on this equipment's actual capabilities

3. Bind Exception Graphic to Equipment

• In Metasys configuration, link the exception graphic to the specific equipment instance
• When operators navigate to Room 340, they see the custom FCU graphic, not the VAV template

4. Document Exception

• Add a note in the equipment description explaining why it has a custom graphic
• Future technicians will understand why this one is different

5. Keep Base Template Intact

• Don't modify the standard template—create a new exception
• This way, all other VAVs still use the template and benefit from updates
