nvoAlarmLog alarm_type[0] Same as nvoAlarm.type See nvoAlarm.type A central node may poll this output variable for a short history of
alarms. It contains the last five alarms reported via nvoAlarm. At
the time a new nvoAlarm is issued, nvoAlarmLog is updated.
nvoAlarmLog alarm_type[1] Same as nvoAlarm.type See nvoAlarm.type See above.

This output variable is a polled output containing a list of all the
current errors detected by the node. A search for error conditions
in the node is made periodically. A central node may poll the
nvoAlarmStatus output for all of the current errors. nvoAlarmStatus
contains all the current detected errors even though they may be
suppressed for reporting by nvoAlarm.
nvoAlarmStatus error_bit[1] UBYTE
Bit coded Alarm:
ALM_COMFAIL_HVACMODE
ALM_COMFAIL_SETPTOFFS
ALM_COMFAIL_SCHEDOCC
