ControlTrends had a chance to spend some time with one of the great controls people in the HVAC and Building Automation Controls Industry. Carl Johnsen’s career with Honeywell spans 43 years, and it was an absolute delight to interview Carl at the 2015 AHR show in Chicago. From his early days selling and supporting pneumatic controls, to the advent of DDC controls, on to the fully integrated building automation control systems of today, Carl Johnsen met the challenges of changing technology with determined optimism and success. Carl Johnsen’s enduring personal commitment and professional contributions, rendered both to the HVAC industry at large, and individually, to each of his customers — are immeasurable, and greatly regarded and respected. Carl Johnsen has set standards by which others in our industry will be measured. And in the words of another industry icon, when a person like Carl Johnsen does retire, an inestimable amount of “tribal knowledge” will leave the building when Carl walks out it doors. Best regards, Carl. You will be missed.
