Nv Name L ON S PEC ™ Ref Name Class Description
nvoAlarmH Alarm Out OUT 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
nvoAlarmLog Alarm Log Out OUT Reports the last five alarms.
nvoAlarmStatus Alarm Status Out OUT 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).
