If you have an "old" Behmor (easiest way to tell is if the colours around the P1, P2 buttons etc. is one colour), then this upgrade will change your roasting life!
There is much more control once you upgrade to a Behmor Plus with the only challenge being the "Unattended Safety Feature" which turns the roaster off 75% of the way through the roast if you don't hit the start button when the console starts flashing.
Automatic voltage setting (if you move your roaster, you should allow it to reset again)

Variable drum speed - 8rpm or 16rpm

Set the "Rosetta Stone"

New Safety Feature
At 75% of the roast, you will have 30 seconds to press "Start" to continue, otherwise the cooling cycle will begin automatically. This ensures that roasting is always attended and should prevent bean ignition at the end of the roasting cycle
