What does Direct Digital Control (DDC) refer to?

Direct Digital Control (DDC) refers to electronic controls used for equipment operation and monitoring. This technology utilizes microprocessors and digital circuits to manage HVAC systems more efficiently. DDC systems are essential for optimizing building performance, as they can provide precise control over various mechanical components based on real-time data and feedback.

For example, DDC systems can adjust settings based on temperature, humidity, and occupancy levels, improving energy efficiency and occupant comfort. The digital nature of DDC allows for better integration with modern building management systems, facilitating advanced features like remote monitoring and data analytics.

In contrast, mechanical control systems involve traditional methods that may not offer the same level of precision or adaptability. Analog controls are less sophisticated than DDC and rely on continuous signals rather than the discrete, programmable capabilities that digital systems provide. Manual control processes require human intervention for adjustments, lacking the automation and efficiency of direct digital control systems.
