The settings associated with this mode of operation are:
• Sampling period (register 321).
• The activation of the probes (register 324).
• Alarm configuration of the probe 1 (register 330) and probe 2 (register 340).
• High threshold of the probe 1 (register 331) and probe 2 (register 341).
• Hysteresis for the high threshold of the probe 1 (register 332) and probe 2 (register 342).
• Low threshold of the probe 1 (register 333) and probe 2 (register 343).
• Hysteresis for the low threshold of the probe 1 (register 334) and probe 2 (register 344).

In this example:
• The product measure the temperature on the 2 probes every hour
• On probe 1, there is a high alert at 70°C with a come back to normal at 65°C and a low alert at 10°C with a come back to normal at 12°C
• On probe 2, there is only a high alert at 23.5°C with a come back to normal at 20°C
High alarm enabling
Value Result
0 Alarm mode
1800 A sample of the temperature every hour
3 The 2 probes are activated
3 An alarm is activated on high and low threshold on the probe 1
700 High threshold is 70°C
50 Hysteresis of the high threshold is 5°C, so the come back to normal is at 65°C
100 Low threshold is 10°C
20 Hysteresis of the low threshold is 2°C, so the come back to normal is at 12°C
2 An alarm is activated on high threshold only on probe 2
235 High threshold is 23.5°C
35 Hysteresis of the high threshold is 3.5°C, so the come back to normal is at 20°C
0 No low threshold determined
0 No low threshold determined
