You need to take a look at the control PCB itself. The link above explains in detail.
In Dylan’s comments above he says: “_I hear I’m one of the first to receive the IBTS sensor upgrade kits. The kit was complete, and the instructions were quite good. _”
I received my upgrade kit today, however there were no instructions at all…where should i obtain these?
Thanks
Thank you Dylan. For those inclined to jump the gun like I did, Aillio will send buyers an email with link to instructions … my email arrived about 4 hours after kit delivery.
hi just got it today installed it, but I do not know if old bean sensor has to be unplugged.
I installed 475 and my R1 reads PH 205°C not 250 or 300 how can I change this?
You leave the old bean sensor plugged in - the RoasTime software shows you both the IBTS (still labeled Drum temperature for now) and old bean probe - at least for us old-timers, it’s really handy to have both, to give you an idea where you would have been with the old roaster. On my setup, anyway, they’re more-or-less parallel to each other after about 2 minutes or so, but the IBTS is about 30C above the old bean probe, slowly decreasing in delta over time.
thanks
have another issue new PH says 250-300°C I only can do PH max 205C and on mac 2.0.9 it does not find the bullet. Driver on Windows was hard to update after 9 times it finally works without old profiles
You need to update the bullet’s firmware after installing the IBTS in order to unlock higher preheat temperatures. The installation instructions (I think) say which firmware version to use - I think it’s the current beta firmware. They’re working on the Mac USB connectivity, 2.0.8 does work with the IBTS, though. A new 2.0.9 should arrive soon.
uninstalled 2.0.9 on mac reinstalled 2.0.8, and downgraded FW to 448, still have PH max 205C what the dell I am doing wrong to get PH300?
Not sure FW 448 supports the higher charge temps used with the IBTS sensor.
I’d recommend staying at RT 2.0.8 and upgrading the FW to 475 and trying to set the charge temp higher than 205.

Indeed - the post install instructions (referred to at the end of the installation instructions) say to use FW 475, for exactly this reason, I believe.
I think you’re right. @jacob told me to use 475 to get my 1.5 Bullet to roast past 220C “drum temp.” I haven’t had a chance to try it, yet, but I bet 475 allows higher thresholds, all around.
yea but in new manual IBTS temp are much higher, I thought we have to put that value
Recommended pre-heating temperatures
| Weight [g] | Pre-heat setting | IBT sensor (V1.5 & V2.0) | Power during roast | Comments |
|---|---|---|---|---|
| 400 | 160°C (320°F) | P4-P7 | For a 10min roast | |
| 500 | 170°C (338°F) | P4-P8 | ||
| 700 | 180°C (356°F) | 250°C (482°F) | P4-P9 | |
| 800 | 190°C (374°F) | P4-P9 | ||
| 1000 | 200°C (392°F) | 300°C (572°F) | P6-P9 (PP) | |
Guess then I have version 1 with new board that had already connector place unused input
205 C I can do and it works now with Mac 2.0.8 only no profiles, tomorrow or Sunday I ll roast first time with new IBTS.

Finally it works I can PH 300°C but it wont save it after power cord is taken off.
anybody got an idea how to save for good.
You’ll have to change it each time until an update is made.
I’m grateful to the Aillio team for allowing us early buyers access to the IBTS upgrade. I learned a lot about the machine in the process of opening it up. The install guide is pretty complete. (Would love to see a video, though.)
In case someone else has this issue: after a smooth hardware install and firmware update I tried a roast. About 7-8 minutes into preheat the roaster suspended preheat (a failsafe mode?) and wouldn’t respond to either the control panel or RoasTime. After letting the unit cool down, it started up normally but repeated the same behavior. I opened up the control panel and reseated the cable connections. Both probe temps were much less noisy and the roaster went smoothly through preheat and roast.
Lessons learned:
- Really check those connections when doing the install
- If you see this behavior try reseating the cables

I installed the IBTS today. I am about the World’s Unhandiest Man, have broken sturdy things more or less just by looking at them and this was kind of a trial, but I have just completed my first roast and it looks really, really good.
The instructions didn’t mention (or I missed) that you have to take off the plastic part that links the PCB with the front plate. I struggled for a while to get the rubber gasket on before realizing that if by a miracle I succeeded, I’d still have to take the plastic part off to get the IBTS on.
Ack.
I was also holding the front plate backwards for a little while; life got a lot better when I turned it over. The photo clearly showed the smooth side; it took some time to register.
Then it took me a while and a YouTube video to figure out how to take the sensor wires out of the six-wire connector and put them in the smaller one and the wires positively do not simply snap in to the new connector but after I pushed really hard and swore at them a little they found their way in.
And then the old bean probe connector cable fell off and I didn’t reconnect it; I’ll have to look up where it goes and reinstall it next time I clean. And I found I have two long screws that I didn’t use, probably they go in the part that connects the PCB to the front plate. Everything seems secure, though.
I ran 605 grams of Java Sunda Gunung Jaladin from a 245C preheat, taking 14:14 to get to 230C, the first snaps of second crack, which is what I like for espresso. This is almost identical to the temperature at which I would cool my roasts when I was using my Quest M3, about 20 degrees higher than the old Bullet sensor would measure.
So, I know I need to go back in and clean up a little bit of a mess, but I think the coffee’s going to be great and I have a probably inordinate sense of pride in my accomplishment.
Someday I may tell you about how I once mangled changing a Halogen light bulb …

I see no reference to “475” at all. The instructions you linked to talk of “beta”. And even show nice pictures selecting beta FW.
Members and support often advise to use FW 475 in this forum, but it is not in the instructions nor manuals, even though everyone says “go read the manual”.

Hey, had this issue too, just open RoasTime 2.0.8 or higher (I have 2.2.0) and click on the ‘tools’ menu on top, then ‘update firmware’ item. It should have a check button on that window and after you check it will offer either a ‘stable’ or ‘beta’ which I think are 448 and 475. Something higher than 448 is required for IBTS.
Note, after it installs the firmware you have to reboot the roaster (both power and usb cable) and the panel will show rES while its updating the IBTS (if you have it) then you have to reboot again.
Now your roaster is on 475.
Hope that helps.
How to take out the the wires out of the six-wire connector is clearly to see in the manual. However, putting the (3) wires back into the four-wire connector was not clearly described. There is only one proper way to have the wire clicked into the connector. If you put it in in the wrong way, it will not click and also make no connection. This should be better explained in the manual.
