become more steady.
Weather Alarms
The weather alarms are settable for when certain weather
conditions are met according to the users requirements. For
example, the user can set the thresholds for the outdoor
temperature to +40°C (high) and -10°C (low), whilste only
enabling the high alarm and disabling the low alarm (i.e.
temperatures <-10°C won’t trigger alarm, but temperatures
>+40°C will).

may cause the weather alarm to sound constantly if the
measured reading is close to user set level, a hysteresis
function has been implemented for each weather alarm. For
