Flexible Combiner 101 (E2/E3): Stop Blaming the Flexie for Everything

On the Advanced Refrigeration podcast, Brett Wetzel and Kevin Compass start by troubleshooting a Raycorp CO2 skid startup where one pump won’t make differential despite drive and check-valve checks, concluding the pump is likely bad and difficult to replace due to skid framing and serviceability constraints. They then shift to a practical walkthrough of programming Copeland E2/E3/Site Supervisor “flexible combiners,” emphasizing that flexies are open applications and many tasks should use simpler sensor controls instead. They stress labeling inputs/outputs, using E3 tools like duplicate tabs for troubleshooting, lowering update time for testing, and avoiding common syntax/type errors. They demonstrate building a timer, a cut-in/cut-out fan control (including averaging sensors), and a leak-detector shutdown using if statements and network variable targets, recommending the flexible combiner programming supplement as a reference.
