Dedicated Outdoor Air System Functional Test

Commissioning inspection template for verifying DOAS outdoor airflow, exhaust air recovery effectiveness, control response, and integration with zone terminal units.

Test Setup and System Identification

• DOAS unit identification matches commissioning plan and sequence of operations
• Test instruments are calibrated and within current certification date
• System is in the intended test mode with BAS overrides documented
• Outdoor air, exhaust air, and supply air paths are accessible for measurement

Outdoor Airflow Verification

• Measured outdoor airflow meets design minimum
• Outdoor airflow deviation from design is within tolerance
• Outdoor air damper modulates smoothly through commanded positions
• Outdoor air sensor reading is stable and reasonable relative to measured flow

Exhaust Air Recovery Effectiveness

• Energy recovery device operates when enabled by sequence of operations
• Exhaust air recovery effectiveness meets project acceptance criteria
• No abnormal bypass, leakage, frost, or condensate issues observed at recovery section
• Exhaust and relief air paths are balanced and free of obstruction

Zone Terminal Unit Integration

• Zone terminal units receive intended outdoor air or ventilation command
• Zone terminal unit dampers and reheat respond correctly to DOAS mode changes
• Ventilation reset or occupied/unoccupied logic follows sequence of operations
• No zone reports simultaneous heating and cooling caused by DOAS control interaction

Controls, Alarms, and Safety Interlocks

• Freeze protection, smoke shutdown, and fan proof interlocks operate as intended
• Required alarms are annunciated at BAS and local interface
• No active unresolved deficiencies remain at end of test
