Course #204-Pneumatic HVAC Controls

 ($175 per person)

Even with the widespread installation of DDC, Pneumatic Control Systems make up approximately 20% of all controls in commercial buildings today. Unfortunately, many of the technicians that worked on these systems have retired. This course is taught by Ron Auvil, who was one of the last generation of technicians to work exclusively on pneumatic controls. In his career, Ron was fortunate to learn many of the tricks of the trade regarding pneumatics from the old timers. He has taught pneumatic controls for both Honeywell and Johnson Controls. This course will be chock full of practical field insights that technicians need to know to maintain and troubleshoot their pneumatic control systems. It will cover multiple manufacturers and generations of controls.
