We'll discuss the similarities between different control systems, basic components and proper installation. We also cover technical aspects, including electronic valves, pressure measurements, wiring and cable specifications for stepper valves. Better knowledge of CO2 control systems will not only help refrigeration technicians troubleshoot more efficiently, but also build much better relationships with customers and store managers. In this episode, we discuss: -CAREL controllers and electronic valves -Controller manual usage best practices -CO2 system pressure measurement challenges -CAREL controller configuration and flexibility -Stepper valve controller safety features -Cable specifications for stepper valves -CPT (calculated product temperature) -PID (proportional-integral-derivative) control -Maintaining controller settings -Refrigeration defrost cycle management Helpful Links & Resources: Episode 340.
