Computrols was founded in 1983 and first began as a service business, providing maintenance for the large building automation systems of the day. The industry was young and these early automation systems required an enormous amount of attention. These were the formative years for Computrols. Founder Roy Lynch and his brother Kevin learned a great deal from their experiences at the time.

“If you are stuck in a building at 3:00 am reloading an operating system with a tape deck, and you can’t leave until it’s finished, the experience will affect you.”
–Roy Lynch, Computrols Founder

Experiences like this are what drove Mr. Lynch and the company to never repeat the mistakes of these early systems. From that time forward, simplicity and reliability have been cornerstones of everything that Computrols creates.

Even today, quality of service is a point of pride in the Computrols culture. Technicians, managers and engineers alike, work together to make Computrols products simple and reliable. Every team member in the company pitches in to ensure quality service.

The PC Revolution

It’s hard to imagine now, but personal computers were not part of early building automation systems. Large, cumbersome, special-purpose computers were the standard. So, in the mid-1980s, Roy Lynch embarked on a mission to bring all of the latest PC technology to the industry, and he did just that. With the addition of software engineer Mike Donlon, Lynch and the Computrols team developed a front-end computer system that delivered all of the latest technology: point-and-click mouse support, historical data archiving, graphics and more. Computrols was the first company to bring PCs to expansive building automation systems.

Taking Control

Computrols Owners - 1990s
The next step in the evolution of Computrols was to produce their own line of products for HVAC control. In the early 1990s, the DDC1 and its cousins were workhorse controllers that laid the foundation for generations of controllers to come. Two-board design, large screw terminals, and easy addressing were just some of the features that have become mainstays of the Computrols product line.


Today Computrols not only offers interface solutions to a plethora of 3rd party systems but also has a complete product line of field controllers enabling us to provide turnkey solutions for our customers. As a leader in the manufacturing of intelligent controllers for smart buildings, Computrols prides itself on being the industry’s only manufacturer to offer a lifetime warranty on all DDC controllers.
