What condition triggers the AUTO PRESS (YELLOW) alert?

Explanation:
Auto Press (Yellow) signals that automatic pressurization control is no longer available. On the CRJ-550, automatic control depends on the primary cabin pressure controllers. If both CPC1 and CPC2 fail, there’s no automatic way to maintain cabin pressure, so the yellow alert is shown to warn you that auto pressurization is inoperative. If only CPC3 fails, auto pressurization can still be provided by CPC1 or CPC2, so the alert wouldn’t be triggered. A general pressurization loss is a broader fault and would present differently, while auto press engaged is simply the mode in use, not a fault condition.
