amount of Rate applied when the input is outside of the Proportional Band. The ArtE
time and the rtE time are independent and have no effect on each other. To
increase damping effect and reduce overshoot set the approach rate time for a value
greater than the natural rise time of the process (natural rise time = process value
time to set point).
