The modifying signals of variable value (analogue IN or motorised potentiometer) can modify he reference signal
according to the following relationship

Normal modification: modified reference signal [%] = reference signal [%] - lower [%] + modification [%] x K
Inverse modification: modified reference signal [%] = reference signal [%] + lower [%] - modification [%] x K
Discrete modification (digital input, virtual input or PID extender):
n = number of the active units
Normal modification: modified reference signal [%] = reference signal [%] + n x discrete value [%]
Inverse modification: modified reference signal [%] = reference signal [%] - n x discrete value [%]

1-10-2 change-over points
The change-over frequencies of the PID regulators, if frequency depending PID regulation has
been selected. The change-over is implemented with hysteresis to avoid possible swingings.
