All difference values diF = INP-IN2 are shown in the picture.
Inside the valid range (green) all values are smaller than the
setting for the difference ALd = 50.
INP = 101°C, IN2 = 50°C
101 - 50 = 51 exceeds Ald = 50 and lies out of the valid range.
INP = 50°C, IN2 = 50°C
50 - 50 = 0 and lies inside the valid range.

Example 2:
The area between the dot and dash lines indicate
the span of the hysteresis (factory setting: 1K)
he inputs INP and IN2 are additionally monitored
in regards to the limit value AL=150°C
