Issue
Xenta 102-AX version 2.14 and prior will not honor nviSpaceTemp unless it is bound with a true SNVT binding. This can be an issue in a Vista classic scenario using a Xenta Server to do the connection in XBuilder.
Product Line
TAC Vista
Environment
Xenta 102-AX version 2.14 or prior
Vista Classic Network
Cause
The Xenta 102-AX version 2.14 and prior requires a true SNVT binding on nviSpaceTemp from an LNS Management software (LonMaker, NL220). The controller does a check to see if there is a true bound value on the nviSpaceTemp and if it does not exist, it reverts to the hard-wired room temperature sensor.
When using the Xenta 700, Xenta 500, or Xenta 900 the controller simply connects the desired temp value to nviSpacetemp via a connection object. This is not a true LNS binding and the controller WILL NOT honor the connected value.
Resolution
Upgrade the firmware of the Xenta 102-AX to version 2.16 or later. Firmware 2.16 allows the use connection objects in XBuilder to send a value to the nviSpaceTemp SNVT of a 102-AX.
