A possible solution is to make a timer logic in LM, that sends a 1bit to a KNX group adress every 5 minuttes (i am alive signal / Heartbeat).
In your KNX network, if you have a physical komponent with a simple logic-module built in with timer function, you could maybe have a timer in that component which recives the 1bit (i am alive signal / heartbeat)from LM which triggers its reset input every 5 minutes.
If the timer in your physical component don't recive the 1bit from LM before the timer runs out of time, it can send a 1 bit to another group adress, where you can use that adresse to activate/deactivate heating/coling or whatever you want.
