Check the maximum allowed TEC current in the datasheet of your TEC
element.
•
Select the display I
TEC LIM
.
•
Change the limit value of the TEC current to the desired value with the
screwdriver-potentiometer besides the LED I

.
1.6.2 Setting the maximum allowed temperature
To set the maximum allowed temperature (or the minimum allowed resistance):
•
Check the type of temperature sensor in your setup.
•
Select this sensor in the field marked “SENSOR“.
•
Select the display T
