The table shows an example with factory settings and with inverted status function for LED3.
The switching points are defined as follows:
= 70 °C, = 65 °C
= 80 °C, = 75 °C

Here you can invert the status function of LED for a contact: the LED is illuminated when the contact is opened,
thus falls below the minimum temperature, and when the LED is illuminated the status „error“ is displayed.
Especially the recording of incidents depends on the illumination of LED (see chapter 4.9 Diagnosis, ).
