Default leak monitoring is enabled, and can be disabled by LM parameter in the St-8 menu.
The process works as follows: Water / oil TCU units:

Will activate the audible alarm by turning off the pump and heating temperature control unit.
Once the user has disconnected the pump switch and confirmed the alarm by pressing
