A technician is unable to diagnose an intermittent high-pressure lockout fault on a Bard wall unit despite extensive monitoring and testing, causing repeat service calls and customer frustration.

Workarounds Described

• Manually monitors pressures and temperatures for hours without fault capture
• Uses thermal camera to check motor temperature
• Forces high-pressure condition by restricting airflow to test switch

Implied Software Gaps

• Automated diagnostic data logging that captures intermittent faults without technician presence

FaultCapture HVAC

An intelligent diagnostic logger that continuously monitors HVAC system pressures, temperatures, and electrical parameters, automatically capturing events leading up to a fault. It provides remote alerts and detailed trip reports, eliminating need for prolonged on-site observation.
