Issue
The maximum stat adjustment range that can be set using the Xenta 102-AX Plug-in is 10°C (17.98°F) or roughly 5°C (9°F) above and below the base setpoint. This limitation is applied to the 102-AX Plug-In, Operating Parameters, Stat Adjustment Range.
Environment
Xenta 102-AX Plug-in
Cause
The LNS Xenta 102-AX Plug-in limits the values that can be written to the stat adjustment range parameter.
Resolution
Write to the stat adjustment range variable through Vista Workstation. There is no limitation applied to this value when the LNS Plug-in is not being used. The point can be found in the Xenta 102-AX controller at VAV_Controller.nviSetpoint.SCPTmaxRnge.
If the 102-AX Plug-In is accessed after the change, the plug-in will limit the value again resulting in 10°C (18°F) being written back into the 102-AX.
