If the unit is off on a shutdown alarm, or running but in a limit alarm condition, the cause, date/time,
and UNIT STATUS will appear in the ALARM ACTIVE screen. The remote alarm relay will close,
and a red light will appear behind the LEFT button. The light will go out when the fault is cleared.
If there is a simultaneous occurrence of more than one alarm, the others will appear in additional
screens below this one, accessed by the DOWN ARROW.
If an alarm occurs, press the MENU button, then the LEFT button for ALARM, and then the left
button again to reach the ALARM ACTIVE screen.

scroll down to the last screen (bottom screen above) and press ENTER. The SET UNIT SPs screen
will appear and the password will be asked for. Press ENTER and the cursor will flash in the
password field. Press the UP button to scroll the numbers up to the required password. Press
ENTER to enter the password. Then return to the ALARM ACTIVE screen and press ENTER to
clear the alarm.
