DN - Moves valve towards closed position.

Mode SEL Switch

Auto - Automatic mode is operating. Outflow valve is controlled by one system at a time.
MAN - Allows manual control by the MAN V/S CTL switch. Illuminates white when selected. The cabin altitude indication on the ECAM PRESS page may fluctuate when switching from AUTO to MAN.
Fault Light - Illuminates amber only when fault detected in both automatic systems.

LDG ELEV Selector

Auto (Detent) - Pressurization system uses FMGS-determined landing elevation to optimize pressure schedule.
Other Positions - Pressurization system uses selected value for landing elevation reference in the event of an FMGC failure or incorrect landing elevation in the database. Actual value is displayed on the ECAM CRUISE and PRESS pages.

Ditching Switch ( Guarded )

Normal - Selects normal system operation.
ON - Commands operating system to close the outflow valve, emergency ram air inlet, avionics ventilation inlet and extract valves and pack flow control valve.
