3.3.9 The unit is programmed with an adjustable high temperature alarm. The
high temperature alarm value is factory defaulted at 5°C above the set
temperature value. To change this value, follow the steps below.

and will alternate between “Alar” and the current high temperature alarm
value.

temperature alarm value.
