Topic: Tricking the Behmor to roast in a cold garage (25 msgs / 503 lines)
1) From: Paul Helbert
When I bought my Behmor half a year ago, I had no idea it had such a narrow
design range of ambient temperature.
The first time the temperature went too low I got an error message and I
just waited until the day warmed up somewhat and all was well. But winter is
coming and it is beginning to happen more frequently, so here is what  I've
been doing lately:
Hit 1/2#. start and it runs a few seconds before shutting down.
Hit stop, 1/2#, start and it repeats the short run and error shut down.
Repeat until enough heat has been created by the mini starts that it will
run a one minute warm up. (Half a dozen tries from 40F at 120VAC).
Stop the warm up, add beans and operate normally.

I've roasted with my Behmor out on my porch in pretty cold weather, but I d=
idn't store it out there. Keep it in the house until you're ready to roast.=
 Easier than what you've been trying...no?

I agree with Charlie.  It has that 'narrow range' for a reason 
(although 40-90 F I don't really call narrow).  It is to keep 
condensation off of the components (circuit boards) and thus minimize 
component failure.
Keep that in mind while you 'trick' your Behmor.  You may be tricking 
your self into a shorter lifetime for it.

How about for the cold weather Behmer users it would be easy to build or 
find something to store the Behmore in and say a 40-60 watt light bulb  
you can turn on the light  a little before roasting  should work easier 
than restarting it (just a thought). Ray

6) From: Brian Kamnetz
I don't have a Behmor, but I'm wondering if the old air-popper trick
of putting it into a cardboard box in cold weather might not work for
the Behmor too. Could you store it indoors, and take it out into the
cold only to roast, and while out in the cold, keep it in its own
"environment" in the box?

Pre-heat the roaster in the house without beans. There will be no smoke or
odor. Then carry it outside and roast.

Last winter, I kept the Behmor inside and took it into the garage when
I needed to roast.   I've never seen any error message on my Behmor.

If it is just kept indoors, there is no need to even pre-heat it.  It 
isn't that sensitive.
As for the box idea - it isn't that you need to conserve the heat 
during the roast.  It just has a component safety feature to keep it 
from being stored in the cold damp area.

Cold and damp or just cold? Pretty sure just cold not differentiating damp
or arid, i.e. not monitoring humidity just temp.

True, it does not differentiate humidity.  The combination is simple 
what the engineers are trying to avoid.

13) From: Paul Helbert
Based on all the good feedback I reckon I'll continue to keep my Behmor in
the garage (which is soon going to have two operating overhead doors) and
make a little hut for it (maybe convert an old cooler) with a 15 watt
appliance bulb or some similar low wattage heater to keep it cozy between
uses since I can't see myself lugging it back and forth to the house two or
three times a week until spring.
 I tried to make that the mother of all run-on sentences but failed
miserably. WYSIWYG. Must be the cold. Gotta get more coffee.

John your idea about using the behmors light. I could be wrong but I think
I read somewhere  that when its plugged in there is a transformer
energized?? So might not be to good to leave it plugged in to long. I
could be wrong (first time) :) Regards Ray

If you don't mind keeping it one, you might try just leaving the 15 W 
light on that it has in it.  That in itself may keep it about 40 
F.  Seems a lot simpler.

16) From: Dave Ehrenkranz
I do believe you are correct. In order to keep the light on you need  
to keep it plugged into a live circuit which keeps the transformer  
energized. I don't know why it is designed that way but someone else  
might. I have mine plugged into a surge suppressor which allows me to  
flip a switch on the suppressor and to make sure the unit is not  
getting power without having to unplug the unit.

The manual (page 3 in digital PDF file) states.
"8. Unplug The Behmor 1600 from the outlet when not in use and NEVER  
operate The Behmor 1600 with a
damaged cord or plug. Do not immerse cord, plug or The Behmor 1600  
itself in water or other liquids. To
disconnect The Behmor 1600 must not be running, then properly/firmly  
grip the plug and pull from wall
outlet. Do not pull or tug on the power cord"
I know this doesn't tell you why but I remember hearing (maybe from  
Joe Behm?) that the transformer stays on which is what Ray also states  
below in his email.

19) From: raymanowen
These little transformers are known as "control transformers," and in many
digital electronics devices, they are energized 100% of the time.
Transformers are "potted" if they have to endure some periods de-energized
in condensing atmospheres. They make very little heat.
The reason for the energized transformer is to keep the microcontroller's
volatile memory from forgetting if the battery goes to sleep.
Rather than energize the roaster's heater intermittently to warm and
dehumidify the roaster, a 2.5 K ohm - 3K ohm wirewound ceramic power
resistor would generate about 5w of heat when connected to the 120v power,
if the roaster stays powered when turned off.
If you want to see it really run funny or not at all, keep on completely
unpowering it when you're not using it. The instructions probably have
words  to that effect- it's like your computer in that respect. I'm just
imagining all this, but RTFM and suit yourself.
The machine's basic instructions should be firmware flash memory, and
<Snip>
time, maybe even several weeks...
If the battery gets low, the Behmor might think it's an expired parking
meter and send an Onstar signal to disable your car.

20) From: miKe mcKoffee
The firmware would be nonvolatile memory not volatile, and as such can be
unplugged virtually indefinitely as can any computer without it "forgetting"
it's a computer. Sure non-firm BIOS settings will be lost if battery backup
dies, but it'll still be a fully functional computer. I HIGHLY doubt the
Behmor is using battery backed up memory since you cannot changed it's boot
up (power on) behavior through modifying it's BIOS settings.
99.999% you're off base on this one RayO.

well, the question has not changed.  Why unplug it?  Yes, Virginia, I 
read the manual.  The computer has been powered up almost continuously 
for better that 7 years now and has yet to explode in a ball of flame 
and smoke.  The boob tubes across the fruited plain are continuously 
energized with no harm to the device.  Does not sound like an electrical 
issue to me.  There must be a reason...  I seem to vaguely remember 
something about powering down to force a reset of the logic.

23) From: Bob Hazen
I suspect the smarts in the Behmor are fully contained in firmware - no 
battery in there.  I also suspect the reason we're instructed to unplug the 
roaster when not using it is all about the ETL safety certification.  ETL is 
like UL.  They review the design for flaws that might hurt you or burn your 
house down.  "Unplug when not in use" is likely boilerplate resulting from 
their requirements.  The same reason the instructions for my toaster oven 
and microwave say unplug when not in use.  Now who unplugs their countertop 
appliances?  Especially when you have to reset the clock when you do? 
Anybody ever see a TV manual that says "unplug..."
Bob

24) From: Alchemist John
You nailed it.  I asked Joe about this and that is it.  ETL.  It is 
the same reason there are maximum roast times.  ETL directive. As is 
the three warning labels and printed safety warnings.  ETL 
requirements.  Not back, just cautious.
And yes - there is no battery.  It is all non-volatile firmware.
