Well I took a couple of months to get back to calibrating my new Savannah.
So for the last week or so I’ve been trying to get the basics down such as outlo, rtd offset and the auto temp....I must admit it has been a struggle.
The first day I followed savannahs video for setting the above.
It was over 100 degrees here in central OK and I had direct sunlight on my smoker...so maybe not the best conditions to be setting these adjustments but I assumed that once set the PID would accurately adjust to the conditions. Well I was wrong.
I got the rtd offset/PB1 set to plus 25 degrees and gradually reduced the Outlo/auger to 7 to get close to 150 degrees setting for the SV that was stated in the video and manual. Once the PV got to 160 and seemed to stabilize I moved the the SV to 225 and tried to let the temp stabilize to run the auto temp.
However, although the ambient temp was still mid 90s but the sun had moved off my smoker and evidently affected the previous adjustments. The PV temp continued to drop to the point where the fire went out. It reignited on a few occasions but would not stay above 150. So I would start anew tomorrow.
THe same scenario followed the next few days as I tried to find a balance between the ambient heat and direct sunlight but basically ended up with the same result. I never got satisfied with the stabilization at 225 to run the auto temp.
So a cloudy, cooler day moved in and I tried the above adjustments and ended up with an outlo/auger at 9 and the rtd/PB1 at +20. Then I ran the auto temp and it seemed to have adjusted to the conditions at that time but we will see...
The Rtd offset/ PB1 seems to be a moving target. At 225 it seems to be close to accurate but at 180 it is usually off by 7-8 degrees on the low side.
I wonder if for every different season I’ll have to recalibrate the above settings. If so, that would be disappointing.
