Issue
When writing the invalid value (163.835) to the Airflow Reset (%) in the Xenta 102-AX plug-in, the value is only changed to 163.830 and the airflow setpoint is set to the Maximum airflow setpoint.
Environment
Xenta 102-AX plug-in
Cause
The Xenta 102-AX plug-in does not support 3 decimal places of precision and will only write a 163.830 value to the device. The plug-in will state this is an invalid value because it is over 100, but it will treat the airflow reset like it is configured as 100%.
Resolution
- Power cycle the Xenta 102-AX controller to revert the nviAirFlowReset SNVT to the invalid value (163.835)
- Use the LNS Browser to manually write the value 163.835 to the nviAirFlowReset SNVT on the VAV Controller function block.
