Sensor offsets 

The controller has a sensor offset parameter for every sensor (P200..P216). It can be used to correct 
the indication by the inaccuracy of the sensor and (partly) the measurement circuit of the controller. 
If  the  controller  indicates  too  much  for  a  temperature  sensor  –  for  example,  2˚C  –  the  offset 
parameter of that sensor must be lowered by 2 K.
