Step 5: Selecting the Temperature Control Value Source and its Connection Details

The temperature control value source has to be specified with the DIP switches 5 and 6. By default, the sensor’s type, served by the controller’s inputs U1 and U3, is the 10K3A1 NTC.

The temperature sensor type can be changed using the iC Tool software.
