Upper deviation alarm, when the
temperature exceeds (temperature

℃
, turn off the
heating. When the temperature is
lower than (temperature setting

,
turn
off
the
refrigeration. The abnormal indicator
light is on and the buzzer sounds.

2 minutes, the buzzer keeps beeping
and all outputs are turned off. It must
be powered off to recover.
