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.
Note: The temperature or humidity data will keep flashing even after the weather alarm has been
switched off by a button press. The flashing value indicates that the current weather condition is out of the
pre-set weather alarm limit(s).
