In this electronic age that 9999 means AFAP (As Fast As Possible) whether going up or down seems archaic. I know there are limitations on the displays they use but I bet for a few bucks more most people would be happier with something more understandable. I understand that setting 9999 puts the kiln to the MAX ramp rate it can do, so why not say MAX Up/Dwn or even MAX with an arrow up or down. Fact is the engineers I have talked to at kiln makers outsource the controller design.
