LAMA Books has releasedDigital Controls for HVAC Technicians, designed to provide plain talk about direct digital controls (DDC) for techs in the HVACR industry.

The author, Leo A. Meyer, said he eliminated the DDC engineering jargon from his book, “jargon that can be overwhelming,” according to him. The book is designed to help techs understand how a digital control system works with an HVAC system, how to use it, and how to troubleshoot it.

“You’ll find how simple HVAC with DDC can be and how simple troubleshooting is with DDC,” said Meyer. “Actually, it is a simpler system to work with than other systems.”

The book has a step-by-step troubleshooting chapter, which shows a tech how to find where a problem is without leaving the main computer. It also has a DDC glossary, diagrams, and illustrations.
