There is an offset in the auber PIDs to help calibrate the temp sensor. It is a +/- value you can set. Read the manual. The setting variable you need to change is "Pb".
If you are using a thermocouple, good luck. If the PID changes temp (i.e., gets warm), the reading will be incorrect. This does not apply to thermistors and RTDs.
Now there's some take delight in the carriages a rolling
and others take delight in the hurling and the bowling
but I take delight in the juice of the barley
and courting pretty fair maids in the morning bright and early
