Sounds like a good marketing tool does it not?
Not much actually as I am not into process control in any way and PID, Feed Forward etc therefore do not do much either. However, things could change and then I would have to investigate and find out waht it does.
I can only comment that any temp controllers I have used in the past with this feature have worked pretty well.
Peter, from what I have seen you are possibly the best one here to comment, and you have in the past. There is a vast difference between what you do and a simple temperature controller.
I rather enjoy designing and building generator systems actually rather than process control or motion for that matter. The only process control job I did I did not enjoy because I had to work alongside/fight with Honeywell. They are very good at coming up with a load of you know what when they are in trouble or behind to apportion blame and direct attention in another direction. Much more comfortable with where my expertise lies.
