Widening the pressure control differential has what effect on the cycle?

• A. Increases energy consumption
• B. Reduces number of starts
• C. Increases the pressure difference between cut-in and cut-out
• D. Decreases run time

Answer: (C)

The key idea is the pressure differential between the points where the system starts (cut-in) and stops (cut-out). Widening that differential means you’re increasing the gap between those two pressures. So, the cycle now runs from a lower start pressure up to a noticeably higher stop pressure, producing a larger pressure swing each time. That direct effect—a bigger pressure difference between cut-in and cut-out—matches the concept being tested. As a consequence, you’ll also see fewer on/off cycles over time and the on-time per cycle tends to be longer, but the defining change described is the larger pressure gap.
