Note:
When you purchase a two-output type controller and use it in a one output capacity, larger overshooting or undershooting may happen as
a result of integral operation. Therefore, we recommend you to choose a one-output type.
The cause of the above-mentioned problem is that the positional relationship between the proportional band (PB) and the set value (SV)
of a one-output type controller differs from that of a two-output type.
