DDC Control Loop | Building Automation

DDC Control Loop | Building Automation - Direct Digital Controls are nearly everywhere in commercial and some industrial processes. We have several articles here at High Performance HVAC, which describe the basics of DDC and how DDC works. There is also a page here concerning DDC, where we describe the process of DDC, including the DDC control loop.

We wanted to make the process a little simpler for the layman audience and to make it more helpful for the new HVAC technicians and Control Technicians to learn the process in simpler terms. In the basic control loop, we have input, processing, and output.
