For connections at the configuration and service interface, note that voltages > 10 V at YC
cannot be processed.
To ensure the functions at YC, only one cable may be connected at a time; either the cable
for the air volume flow reference signal DC 0/2…10 V (setpoint), or the cable for the com-
munication signal.
