First crack settings
When turning on First Crack Detection, the following parameters can be adjusted:
BT Threshold
This setting determines the bean temperature that must be reached for First Crack Detection to start registering single cracks. It is set at 185 degrees Celsius by default. You can adjust the temperature to your liking by tapping the number and then using the rotary knob to change the value.
Trigger count
Here you can set how many cracks are needed to register the “First Crack Event” automatically. It is set at five by default. We recommend 3-5 cracks. You can adjust the number of cracks to your liking by tapping the number and then using the rotary knob to change the value.
Watch the video below to see in detail how to set up the FCD on your roaster.
Registering a first crack event
After tapping “yellowing” or after the BT threshold has been reached, the first cracks can be registered. Once the set trigger count has been reached, the Auto Drop countdown will start.
