3.1 Display
The display shows the temperature in the range –50°C to +150°C in the models with temperature inputs only and in the range -199 to +800°C in the models
with universal inputs. The temperature is displayed with resolution to tenths between –19.9°C & + 99.9°C. Alternatively, it can show the value of one of the
analogue or digital inputs, or the set point (see parameter c52). During programming, it shows the codes and values of the parameters.
