HCC/S 2.x.x.1: What should be considered by using the function "safety shutdown"?

When the function is activated, the temperature for the corresponding limit sensor can be received via a communication object or via the physical device input. If the device input has been selected, the HCC automatically uses the input a. This must be voted on accordingly.

In other words, the use of the temperature input must also be done internally of the device. If it is used externally (via KNX), the safety shutdown would be permanently active because no valid value (no sensor connected to input a) is received!
