Preinstalled Phidget
There are four different setups:
3-sensor-setup: Bean, Inlet, and Drum

Locating the Phidget 1048
To accurately configure your Diedrich's connection in the Roasting Intelligence (RI), we recommend that the preinstalled Phidget must be found inside the machine.
The location of the Phidget may vary from machine to machine.
For reference, please refer to pictures of the Phidget, taken from inside of Diedrich roast machines.

Identifying the temperature measurements
Next, we recommend that you identify and label the probes by measurement (e.g., Bean temp, Inlet temp, etc.). Simply, follow the cables for each probe; from the tip of the probe to its end, where the probe connects to the Phidget.
Once the Phidget has been located and labeled, we recommend taking pictures of the Phidget for later reference when establishing a connection to the machine.
