I have found the PID keeps the increase at 10 deg C. Kevin, what have you got the SV temperature set at? I have put mine at 300 degrees to keep the rate of increase up there, and I was wondering if yours is lower. I think default was set at 210 degrees C. As it gets closer to the SV temperature the rate will slow and then maintain. This is the PID working. I have been trying to get into the Menu to set the "Proportional" value to try to increase the rate but have not been successful in finding it in the Fotek M21 (this is the PID that comes with the machine) menu. With the PID rate rise set at 10 degrees, charge temp becomes critical since there is no way to increase this rate on the elements alone. You will need to use strategic air flow changes to give the temperature a jump during stages if you are aiming for a specific end roast time.
I have just had a "play" with the CCR's settings and as advised, reset the SV from 230 back to 300 as it was when delivered. Don't know if you have got into the "P" and "I" settings yet, but; I found the "Proportional" value by pressing and holding the Shift and Function key (2nd from left) for 3 secs, then the "Set" key twice brought up the "P" setting. Mine is set at 36 but on the instruction sheet, the default(?) shows 25. Pressing "Set" again gets "I" (Integral Time) with mine set at 80 and the instruction manual shows 150. Keep pressing "Set" to get out of the menu. What's your view on these settings (36 & 80) and what is yours set at? Cheers. :coffee2:
