After a successful career path that led him to chairing the ASHRAE Technical Committee, Bill Chapman co-founded ASI Controls in 1986 to provide innovative, reliable, scalable digital control products for HVAC control, building automation, and energy management applications.
Since introducing terminal unit controllers to the U.S. market in 1987, the company has been an innovator and early adopter of key DDC technologies, including Ethernet connectivity, object-oriented controller programming, OPC interoperability, web interfaces, and automated demand control. Among its successes, ASI Controls developed the first distributed database and control hardware and provided early methods of open systems interoperability.
