Evaluate the thermistor resistance for the desired set temperature.
Select with the display selection keys (see Figure 1) the display value "T
the set value and set the evaluated resistance value with the TEC main dial knob.
If the thermistor characteristic R(T) is given in the data sheet the desired resistance
can be read directly.

1.9.4 Connecting a temperature sensor AD590 or AD592

An IC-temperature sensor of the AD590 family is set up between pin 10 and pin 11.
These sensors will map the temperature into an equivalent current that can be
displayed and set directly in °C.
