The curve rises gradually, and a long stabilization time
is created, but overshooting is prevented.
Overshooting and hunting occur, but the set value is
quickly reached and the temperature stabilizes.
It takes a long time to reach the set point.
It takes time to achieve a stable state, but overshooting,
undershooting, and hunting are reduced.
Overshooting and undershooting occur.
Hunting occurs.
The Digital Controller starts up faster.
Overshooting, undershooting, and stabilization times
are reduced, but fine hunting occurs on changes in the
