PZM Override Codes

PZM override selection provides testing of certain system functions regardless of normal program instructions, as long as test conditions are met. When a test is selected, current mode of function will be displayed as a percentage on Driver Information Center (DIC). If test conditions are not met, DIC will display "==" instead of override value selected.

DIC display will alternate between "--" and normal programmed command. Pressing WARMER button will increase override value and pressing COOLER button will decrease override value. Upon release of button, display may either remain at overridden value or automatically return to normal program control, depending on which function is being overridden. Selection of another override test will cancel current override.
