If ActivateRecoverMode = TRUE, the operating mode that is saved in the Mode parameter is
activated. At the start of pretuning or fine tuning, PID_Compact has saved the value of State
in the Mode in/out parameter. PID_Compact therefore switches to the operating mode from
which tuning was started.
If ActivateRecoverMode = FALSE, the system switches to "Inactive" operating mode.
