Sample interview questions: Can you explain your knowledge of different types of control panels used in hydronic systems and their programming requirements?
Sample answer:
Types of Control Panels in Hydronic Systems:
1. Basic Controllers:
– Simple on/off controls for boilers, pumps, and valves.
– No programming required; typically operated manually.
2. Programmable Controllers (PCs):
– More advanced controls that allow for automated operation.
– Can be programmed with temperature setpoints, time schedules, and fault monitoring.
3. Direct Digital Controls (DDCs):
– Sophisticated controllers that provide real-time monitoring and control.
– Can integrate with building management systems (BMS) for remote access and optimization.
Programming Requirements:
PCs and DDCs:
- Ladder Logic: A graphical programming language used to create logic sequences and control routines.
- Sequence of Operations (SOO): A step-by-step sequence defining how the system operates in different conditions.
- Temperature Contro… Read full answer
