From what I remember that controller didn't have much memory, so had a limited number of ramps per program. I think candeling or a slow start had to be a separate program, but I could be wrong.
A ramp of 204oC looked to fast to me so I never tried it, I havenâ€™t experimented around much with different rates. After a 60min soak at about 80oC, I do the almost 150oC \ hr (300oF) to temp for bisque.
There are so many different firing schedules out there from manufacturers and potters, I find it confusing.
