Details of each parameter.
a) AH1, this is the high limit alarm for probe 1. Users can set the temperature so that if
the system is out of control, the buzzer will be turned on. e.g. If AH1 is set to 290, the
buzzer will turn on at 291 and off at 290. When the buzzer is on, the left window will flash
between AH1 and the current temperature.
b) AL1 is the low limit alarm for probe 1. e.g. If AL1 is set to 100, the buzzer will be on
when temperature drops to 100. It will turn off when the temperature reaches 101. This
alarm is suppressed when first powered up. It will only function after the temperature has
reached the set point once. When the buzzer is on, the left window will flash between
AL1 and the current temperature.
