Sometimes in back to back roasting (pressing F1, setting preheat temp, then pressing PRS when ready to start the next batch) the cooling fan stops blowing when the new roast starts, before the previous one has been cooled. How do I make sure it stays on, or how do I turn it back on?
The sequence I use successfully while the roast is cooling…
- Press PRS
- Press F1 which should display the current Preheat setting
– if the setting is wrong then press + or - to get what you want.
– if the setting is ok, move on to… - Press PRS
The 2nd time you press PRS it should launch Preheat while continuing to Cool the previous roast.

this might be because bt is over 190c, i dont know why theese 2 things are realeted i wish aillio would remove it
if i ph to 310 on ibts my bt 195-200 and then cooling stops and i have to start it is sooooooooooooooo anoiring, specaly because i cant see why the fluff the “feature” is there
I will try this, I have always set the PH temp in RoasTime - it doesn’t make sense to me that doing so would trigger the cooling fan to stop though.
After preheat, do you then press PRS to charge the beans and start the roast or do you let the bullet auto-start the roast? In my experience, the bullet doesn’t always start the roast so I always push PRS when I charge the beans.
In my last 2 sessions I had 7 roasts, 1 of them the bean temp probe was below 190C at charge and the other 6 were above 190C at charge. In all of the roasts the cooling fan was shut off immediately after the beans went in, so if the bt being over 190dC was the problem, you’d expect that the roast that was at 125C would have allowed the cooling fan to continue, but that wasn’t the case.
My between batch protocol was: After dropping the beans I pressed F1, set the preheat temp in RoasTime, allowed the roaster to preheat until the the temp was reached or the IBTS ambient sensor got to 78C, and pushed PRS as I charged the beans. My house is fairly hot, and I regularly get an ERC 0004 code if the ambient temp sensor reads 80C or more, but I can’t always predict what charge temp will trigger it.
i do
when the roaster starts cool, f2 then prs, then ph starts and cooler runs
3-4 min in or when she say charge i drop beens, if bt is under 190c the cooler runs if over it stops and i have to manuel start cooling while the roaster roast

i had same problem with the ibts sensor
u have to take the whole panel and eletronic out so u van get into the ibts, the housing is proberly very very durty, find the video on aillios page how t install ibts so u have a guide for duing it, it is easy enogh, just take you time dont stress
and check in info panel how many rpm your ibts fan is running when u roast, 14-16000 rpm it should run
u know u can start cooling again right? 3-5 sec after roast start press f2 until c is there and + for bring it to c9
i looked at your roasts and yes the 3 roast looks wierd, was it ph to temp or??
and why do u roast with f9 all the way?

I didn’t know that F2 would allow you to start the cooling fan again. Thanks!
I checked the IBTS fan, it is very clean, and it usually runs at about 16000. I also cleaned the IBTS. On the last 3 roasts I was ph to temp, but The IBTS sensor got triggered at 80C twice and started beeping an ERC 0004 code. I blew into it to drop the temp and charged the beans which also lowers the IBTS ambient temp and stops the erc 0004 and beeping. My roasting environment is 70-85F this time of year - sometimes I can ph to 310C, but sometimes that is too hot.
Charging at 310C has gotten me the best roasts, with high airflow. I was roasting on F9 to lower the inlet temperature to prevent tipping with a softer Brazilian coffee.
