About your seminar developer: 

Frank Miraglia is currently the Manager of Controls & Automation for Tri-State Technologies, Inc., a multi-faceted contractor offering Mechanical, Electrical, ATC/DDC and HVAC installation services. Having spent twenty-two years in the temperature controls industry working for both controls companies, such as Landis & Gyr Powers (now Siemens Building Technologies) and Johnson Controls, as well as independent contractors, he has been involved in designing, engineering, installing, commissioning and troubleshooting hundreds of electric, electronic, pneumatic and direct digital control systems. He also taught at Pennsylvania State University for seven years as well as having been an instructor for Landis & Gyr Powers. He has successfully completed numerous controls' manufacturers' training seminars and workshops and his style combines this practical knowledge with real world experience to deliver a unique perspective on the subject matter.

Course Workbook:

The seminar developer has written a workbook specifically tailored to this subject matter. The workbook is updated to be as current as possible. It was also compiled with consideration given to its use as a reference tool that can serve the attendee well after the conclusion of the seminar.

Course Description:


This seminar is designed to provide the participants with a working knowledge of how electric, pneumatic and electronic controls operate and how they are applied to commercial heating, ventilating and air conditioning equipment in the "real" world. Emphasis will be placed on how the individual controls work and the interrelationship between them when they are united to create a control "system". Control theory and terminology will also be studied and by seminar's end the participants will be introduced to the latest generation of controls' technology available, microprocessor based controls or, as they are more commonly referred to, direct digital controls.

This online course includes a great reference tool, an Engineering Manual of Automatic Control for Commercial Buildings of almost 500 pages , as well as the instructor's workbook.
