Doug,

I think you have Reset & Deviative mixed up but maybe not.
Proportional Band limits the amount of response to the original Off Set
or a proportional amount.

PB will keep cycling down but has a tendancy to "Droop" Not return to
its original value. RESET will make additional correction to return to
original point but with a new correction force.

Deviative (Like Pepper) needs to be added carefully. It is a ampilifier
of the original off set. It forces the PB to a greater correction force.

Doug, that is a rather quick and dirty explaination. If you want more
contact me off line
