Topic: Behmor P2 Question (5 msgs / 94 lines)
1) From: Seth Grandeau
It seems that the general consensus on the list is that, when using P2 on
the Behmor, you want to set it to have the temperature drop occur right
around the start of 1st crack.  Does anyone know why the team at Behmor
designed the default settings to have the temperature drop occur so much
earlier?
With P2, the B time program is recommended.  For 1/2 lb of beans, this would
have a default max time of 13:00 and the power drop would occur at 7:48 into
the roast.  My 1/2 lb roasts don't hit 1st crack until around 11 minutes.
I'm very impressed with the amount of attention and good design that has
gone into this product, so I assume that the designer wanted the temperature
drop to occur well before 1st crack starts.  I'm just curious as to why and
has anyone actually tried this and what have been your results.
Thanks for any insight anyone can provide.

Joe or John would be the ones to provide an answer as to the thinking behind
it.
A guess, based on results using my Variac in my garage, is that they had
stable 127VAC in an environmentally controlled development lab. That first
crack time starts a whale of a lot sooner at 127 Volt than at 110. Of course
bean type, temperature and humidity are in play as well.

I know for a fact that the 127 VAC scenario is NOT the reason.  Joe 
to special care to design around 'real' voltages.  115-118 iirc, but 
don't quote me there.
As for why, I can't answer that really.  Joe would be the one.  Drop 
him a line and report back.  I may do the same.

I almost always roast 12oz at a time and since I did the mod I've 
been hitting 1C at just about 12.5 minutes. For 12 ounces at P2 I 
start with the 1lb, P2, C and then add time to around 22 minutes 
which bring the drop just around first crack.

Whatever profile I use I max out the time at the end if first crack  
has not completed by one minute remaining.
