[Homeroast] Behmor Err7 - what does it signify?

It means you (I assume) walked away from the 
roaster and didn't hit the button (don't recall 
which) to tell the system to continue at the 75% 
mark.  So as a safety feature, it put the beans 
into cool and gave you an err7.  Basically, the 
new panel has a dead man switch.

 From the Manual (google is your friend)


2)  Auto Safe/ Unattended Switch – at 75% into 
set time of a roast the timer will start blinking un:30..29, 28 etc.. The
user has 30 seconds to press START otherwise it 
will automatically go into cool flashing err7.
