HYSTERESIS

To compensate for fluctuation of the weather data, which may cause the weather alarm to ring

constantly if the measured reading is close to the alarm level, a hysteresis function has been implemented for each weather alarm.

For example, if the high temperature alarm is set to 77°F and the temperature reaches 77°F, the alarm will be activated. If the temperature then drops to 76.8°F (a change of less than 1.8°F) and then increases to 77°F again, the data will blink, but no alarm will be activated.

The temperature would have to drop below 75.2°F (with a pre‐ set hysteresis of 1.8°F) so that the alarm can be produced again. Hysteresis values for the various weather data types are given in the table.
