Alarm Codes

Alarm Code 84 (Restart Null)

Alarm Code 84 is a temporary abnormal condition resulting
from other alarms. The unit shuts down for approximately 15
minutes. The unit will restart after approximately 15 minutes,
or after the condition has reset, and in most cases the other
alarm(s) will have been cleared. If after 3 attempts, the
condition continues to occur, the alarm that caused the
shutdown will appear on the display and the unit will shut
down until the alarm is cleared. Code 84 will automatically
clear after the final attempt at restarting has occurred.
Alarm Code 85
(Forced Unit Operation)
Alarm Code 85 is also a temporary abnormal condition
resulting from other alarm(s). The unit goes into an abnormal
mode which allows the unit to continue to run without shutting
down, the unit may however run with reduced capacity. When
the alarm that caused 85 is no longer active, Alarm Code 85
will be reset.
