Cause of activation
When working, if the probe configured as condensation temperature,
configured as pressure control or as evaporation pressure, measures a value <
Un13 set
Reset
! if the condensation pressure/temperature or the evaporation pressure
measures a value > Un13 + Un14
! With unloading function inserted after the time set Par. Un15
