  • Verify that BAS commands result in the intended physical response at the equipment and space level.
  • Identify discrepancies between commanded values, sensor readings, actuator positions, and actual field conditions.

Alarm Management and Troubleshooting
 
  • Monitor BAS/DDC alarms and promptly investigate conditions affecting HVAC and environmental system performance.
  • Assist the Hospital Engineer in determining the equipment or system condition responsible for BAS alarms.
  • eview BAS trends, histories, control sequences, and associated equipment data to identify the probable cause of abnormal conditions.
  • Modify DDC parameters when authorized and appropriate to restore acceptable operating conditions.
  • Determine when an alarm represents a controls issue versus a mechanical, electrical, sensor, actuator, communication, or equipment failure.
  • Coordinate corrective actions with HVAC technicians, Operating Engineers, Zone Managers, electricians, and other maintenance personnel.
  • Verify satisfactory system performance following corrective maintenance.
  • Assist in modifying alarm parameters and BAS programming to improve alarm effectiveness and reduce nuisance or non-actionable alarms.
Critical Healthcare Environment Support
  • Monitor and evaluate environmental conditions within critical patient-care and healthcare support spaces.
  • Research and evaluate airflow rates and differential pressure relationships for positive-pressure and negative-pressure rooms.
  • Assist with investigation of deficiencies involving room pressurization, airflow, temperature, humidity, and ventilation. Use BAS trends and field observations to assist in determining the cause of environmental control deficiencies.
