If needed, you can change the device to Celsius or Fahrenheit, by utilizing the PID menu
First step: Change the ºC to ºF
Second Step: Change the set point Range in the PID
Third step: Change the calibration points to ºC to ºF
You must change the calibration points adjustment because if the unit is in ºC and you change to ºF you also need to change the Calibration points to ºF to account for the conversion of the temperarature calculations.
