Recently we found that one of the optional functions not listed in the manual actually works great for some situations that is difficult to control by the default setting.
What you need to do is:
1) Enter code 0037, then set "Caty" to1. (the original value was 0), set SF=20 (Don't change the bb parameter).
2) Then, enter code 0036. Change "ot" from 7 to 20. The P, I and D settings should be kept unchanged (the same as the initial setting).
This approach is particular effective to overcome the temperature overshot problem.
