<AL1(2), the alarm is set for absolute low alarm, When AH1(2)=AL1(2), the alarm is
deactivated.
For example, if AH1=250, AL1=249, when the temperature goes up to 250°F, the buzzer will be
on; when the temperature drops down to 249°F, the buzzer will be off.
If AH2=180, AL2=185, when the temperature drops down to 180°F, the buzzer will be on; when
the temperature goes up to 185°F, the buzzer will be off.
User can press the shift key (>) to temporarily silence the buzzer sound alarm. The alarm will
buzz again if the alarm set temperature is reached again. To permanently deactivate the alarm,
