TAC Xenta 301/302/401 are programmable and some SVNTs can be disabled in the default XIF of controllers.
There are several configurations of the controller :
- Integrated into a BMS: All SNVTs are accessible in the XIF
- Stand-alone: SNVTs might be disabled in the XIF and they need to be configured using a special software from Schneider. Usually, this operation must be done by Schneider or their partners.
