The controlled cooling on an Easy-Fire keeps changing. Why?

Question: I do a controlled cooling to get even cooling rates. I've been using the User 6 program for the cooling cycle after using the Fast Glaze to fire up. I've been doing a 2 step cooling, with step one going 200 per hour to 1900 degrees, then step 2 going 150 per hour to 1600 degrees. Whenever I start another firing, step one in the cooling program has changed to 9998 per hour to 2250 degrees, and I have to reprogram it back to 200 per hour to 1900. What's up with that?

Answer: To use USER 6 as a cool-down program attached to the end of Fast Glaze, there needs to be one extra segment in the program before the cool down begins. When you add this program to a cone-fire program, the easy-fire program takes the place of the first segment of the cool-down program.

Your USER 6 needs 3 segments, the first one should be set to something like 200°F per hour to 2000°F, 0 holds. Remember it will not matter what the first segment is set to because the cone fire program takes the place of Segment 1. Segment 2 would then be your 200°F/hr down to 1900, 0 hold. Segment 3 would be your 150°F/hr down to 1600.
