Alarm subnet, node and type.
Alarm subnet is the LonWorks subnet number in domain entry to
which nvoAlarmH is bound. If nvoAlarmH is not bound reports
domain index 0.
0: Invalid subnet (power up value).
1-255: Subnet number.
Alarm node is the LonWorks node number (in domain entry to
which nvoAlarmH is bound. If nvoAlarmH is not bound reports
domain index 0).
0: Invalid entry (power up value).
1-127: Node number.
Alarm type is the alarm type being issued:
0: AT_NO_ALARM (power up value).
1: AT_INVALID_SUBBASE_TYPE
2: AT_NETWORK_COMM_FAIL
3: AT_SENSOR_FAIL
4: AT_INVALID_IO_CONFIG
5: AT_COVER_COMM_FAIL
6: AT_COVER_SUBBASE_MISMATCH
-127: AT_rtnINVALID_SUBBASE_TYPE
-126: AT_rtnNETWORK_COMM_FAIL
-125: AT_rtnSENSOR_FAIL
-124: AT_rtnINVALID_IO_CONFIG
-123: AT_rtnCOVER_COMM_FAIL
-122: AT_rtnCOVER_SUBBASE_MISMATCH
-1: AT_ALARM_NOTIFY_DISABLED
Reports the last five alarms.
Status of the following alarms states:
Communications between the cover and sub-base.
0: No alarm (power up value).
1: The communications between the thermostat cover
assembly and the sub-base has failed in one or both directions.
The data from the cover to the sub-base has not been received
for at least 90 seconds, or data from the sub-base is not
updating the cover assembly.
Output configuration error:
0: No alarm (power up value).
1: The number of outputs configured exceeds the capability of
the sub-base to support them. Considers sub-base type, heat
pump / conventional application, maxCoolStgs, maxHeatStgs.
Sub-base type error:
0: No alarm (power up value).
1: The sub-base is not a valid sub-base type for the firmware in
the cover assembly.
Network Communications Failure:
0: No alarm (power up value).
1: One of the bound network input variables is not being
updated periodically. This alarm may be caused by a failed
node or a damaged LonWorks network cable.
Sensor failure:
0: No alarm (power up value).
1: One of the analog sensors on the cover assembly has failed
or is out of range (high or low).
