The Story

The client needed to validate their ventilation system’s core functionalities to ensure a seamless user experience. Key areas of focus included scheduling, trend view, alarms, plant view, notes, air quality monitoring, and multiple connection types (TCP, direct, cloud). Additionally, role-based access control was implemented to provide different user permissions and control levels within the system.

Our client is a Sweden-based manufacturer of energy-efficient heating and ventilation systems, enhancing indoor air quality through advanced airflow, temperature, and humidity regulation with seamless connectivity across multiple network configurations.

Challenges

• > Inconsistent schedule execution under specific conditions.

• > Data mismatches in trend view, affecting historical records.

• > Alarms not triggering correctly in failure scenarios.

• > UI discrepancies in plant view across multiple devices.

• > Connectivity issues over TCP, direct, and cloud environments.

• > Role-based access control issues, leading to incorrect user permissions.

• > Notes not syncing properly across different user sessions.

The Solution

We conducted extensive functional testing to identify and resolve critical issues in the ventilation system. Our approach included validating scheduling features under various conditions to ensure smooth operation. We verified real-time and historical data accuracy in the trend view, ensuring reliable performance tracking. Alarm functionalities were thoroughly tested to confirm proper failure notifications. Using the Scope tool, we checked plant view accuracy across multiple devices for a consistent user experience. System connectivity was evaluated across TCP, direct, and cloud-based setups to eliminate network-related issues. We also calibrated airflow and temperature sensors for precise monitoring. Role-based access was verified to ensure correct user permissions and control levels. Lastly, we ensured proper data synchronization for notes across sessions, improving accessibility and system efficiency.

The Outcome

The comprehensive testing process improved system reliability, enhanced user experience, and reduced operational risks. The ventilation system now functions seamlessly across iOS, Android, and HMI platforms. By identifying and addressing critical defects early, the system became more stable, efficient, and user-friendly. These enhancements positioned the product as a more competitive and dependable solution in the market.
