APPENDIX B - NETWORK ALARM REPORTING

A T7350H alarm change of state event is reported by the manufacturer defined output network variable nvoAlarmH.
nvoAlarmH Field
subnet
The L
bound, it reports domain index 0.
node
The L
bound, it reports domain index 0.
type The alarm type being issued.
Return to Normal Codes
The T7350 current alarm status is reported by the manufacturer defined output network variable nvoAlarmStatus.
nvoAlarmStatus
Field
coverCommFail Communications between the cover and sub-base.
invalidIOConfig Output configuration error.
sensorFail Sensor failure.
networkCommFail Network Communications Failure.
invidSubBaseTyp Sub-base type error.

Table 14. T7350 Current Alarm Status.
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.
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.
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).
0: No alarm (power up value).
1: One of the bound network input network variables is not being updated periodically. This alarm may
be caused by a failed node or a damaged L
0: No alarm (power up value).
1: The detected sub-base type is not supported by the firmware version of the cover assembly.
