If the unit is off on a shutdown alarm or running, but in a limit alarm condition, the cause
and date will appear in the above screen. If there is a simultaneous occurrence of more than
one alarm, the others will appear in additional screens below the first one, accessed by the
DOWN ARROW. Either type alarm will light a red light in back of the LEFT-ARROW
KEY. The light will go out when the fault is cleared. To clear the fault, scroll down to the
last screen and press ENTER. If other faults have appeared, they will all be cleared at the
same time.
