New features of PID_Temp

PID_Temp V1.1
● Response of the output value on switchover from "Inactive" operating mode to "Automatic
mode"
The new option IntegralResetMode = 4 was added and defined as default. With
IntegralResetMode = 4, the integral action is automatically pre-assigned when switching
from "Inactive" operating mode to "Automatic mode" so that a control deviation results in
a jump of the PID output value with identical sign.
● Initialization of the integral action in automatic mode
The integral action can be initialized in automatic mode with the tags
OverwriteInitialOutputValue and PIDCtrl.PIDInit. This simplifies the use of PID_Temp for
override controls.
