Attention:
The cabinet is equipped with a
digital thermometer
positioned inside the display area, usually close
to the front glass.
The displayed temperature corresponds to the temperature in the refrigerated cabinet; there-
fore refer to this value for preserving the goods properly.
The temperature displayed by the controller corre-
sponds to the set point value. For technical reasons, the temperature values provided by the two displays (i.e. ther-
mometer in the refrigerated cabinet and controller display), even if related to one another, could be different and vary
during the cabinet’s operation. This fact is not an anomaly or a technical fault. To modify the working temperature, it is
necessary to consider the temperature displayed by the digital thermometer
inside the refrigerated cabinet
, and
then increase/decrease to the set point value memorized by the controller. Wait a few minutes after the modification of
the parameter before checking the working temperature of the unit. If it is necessary, repeat the operation, until
achieving the desired temperature.
