Properly binding a CO2 sensor output to multiple Xenta 102-AX VAVs.


From the Xenta 102-AX VAV that is connected to the CO2 sensor, create a binding from the UnivIn3Sense function block/nvoCO2sensor, to VAV_Controller function block/nviCO2 in the receiving Xenta 102-AX VAVs.

It will also be necessary to set the send heart beats by following Lesson Learned Article #4002.
