 No, that was one of the changes between the I-R-1 and the I-R-2.  With the
2, you can program up to 5 stages.  You can also put up to 10 programs into
memory so you don't need to  enter the program each time.

-Whoa! I've had my iRoast2s for a couple months now, and I didn't even
realize that. I could have swore that I tried to input more than 3 stages t=
o
no avail. I'll have to try again! I have actually had some very smooth
roasts with the 3 stages so far, as graphed by real-time data logging,
however I am using really low temp profiles (350/ 3min, 390/ 4min, 450/
5min), and for my hotter-running iRoast2: 340/ 3min, 380/4min, 440/5min.
Note that if you are having trouble understanding the difference between
bean-probe temp and readout temp, be sure to understand that is was ~ BEAN
PROBE temp Tom Owen was speaking of in his datasheet (although not "Officia=
l
bean-probe temp, wich would require special device, rather temp obtained by
placing thermocouple within the "mass" of beans, as opposed to within the
part of the chamber filled only by hot air). If one were to place a temp
probe in a region of the roast chamber with only air, temps would be
completely different, hotter by 30-60 degrees, and thus near equal to
readout on iRoast 2 display (and many times even 30-60 degrees HOTTER than
readout!) By the way how can a company sell a product that is so damn
inconsistant?! That is unacceptable that some iRoast2s are "hot", while
others are not. You know, not everyone has real-time datalogging graph
capability to be able to properly compensate for this! I beleive this is a
major issue Hearthware needs to correct next time around (along with less
noisy, and tighter fitting removable lid assembly)!

...is there some corollary here to the old adage: "A man with one watch =
always knows what time it is, a man with two watches is never sure."?
Why two iRoasts, Jeremy?

- The iRoast chamber size is not sufficient to roast several days worth of
coffee, and I don't like to go through the hassle of waiting 2 hours to
roast another batch. I like to roast all that I will roast in one big
session. I probably could have gotten away with one, and it is a real pain
to lug two outside, and set 2 up, make and save two separate real-time
graphs, and clean 2, and then lug, and store both of them again, (and pay
for 2!); but until iRoast comes out with double capacity roaster, I will be
lugging two around (when I'm not using the gene cafe--- which, by the way I
only have one of, and plan to keep it that way : ) ). But yeah, you probabl=
y
do have a point there. If I had only one, I would probably have more time t=
o
play around with them, and remember to try out those 5 stage settings I've
been meaning to check out. Just would actually be more inconvenient to have
only one. It would cut too much into my shedule (I am a med student). I'll
have to agree with the adage that roasting your own coffee does NOT save
money. By the way, I guess you could say I'm a bit obsessed, too. Wishing
Everyone a Happy Roasting. Peace. Jeremy.

-My new I-R-2 (bought 1 month ago from Tom) came with an insert to the
manual that describes how to set the 5 stages and save the 10 programs.
The insert says it applies to models '40011' and '40012'.  My IR claims to
be model '40010', but has clearly been upgraded to one of the other models,
since it can do the 5 stages.

-Thanks for the info. I just looked again in the manual, and it does say I
can program upto 5 stages. The sad thing is that my eyes actually read over
that line before, and it DIDN'T register. Man, maybe I was lost in all the
excitement or something.... Anyway, I now look forward to trying to smooth
out my roasts even more. I'll be interested in comparing the 3 stage graphs
with the 4- and 5- stage graphs. Man- Just when I got the 3 stages all
figured out to a science, now I have to go and find out if 4- or 5- stages
is smoother!! Happy Roasting.... Jeremy
