A communication card can be purchased so that the ventilation control can also be operated via BACnet/MSTP, Modbus RTU and RS 485 are possible. Together with the card, the smoke and heat extraction control unit WSC 310 / 320 PLUS as well as the MotorController WCC 310/320 PLUS can be used in an automated room climate solution.

Each card provides communication and allows access to the available bus objects depending on the chosen system. Smoke and heat extraction functions have a higher priority than ventilation commands. The fieldbus should only be used for ventilation commands! 
For each motor line, motor group, and smoke section, there is an object that provides status and command options.
