Temperature Control
Settings: The temperature control is preset at the factory so
that the temperature of the refrigerated products is between
+2°C and +7°C (35.5°F and 42°F). The cooling temperature
can be changed slightly. To do this, read the section on
Changing the Setpoint.
Display: The temperature display only shows the
temperature in the interior of the cooling display. The
temperature can fluctuate between +2°C and +7°C (35.5°F
and 41°F). During defrosting, the temperature in the display
may exceed +7°C (41°F), however, the stored products will
still be kept at a temperature that is below +7°C (41°F).
Automatic defrosting: Defrosting of the cooling display
takes place automatically while the unit is running.
Manual defrosting: If need be, manual defrosting can be
initiated. To do this, the defrost button must be pressed for
at least 2 seconds. After defrosting completes, the unit
returns to the normal operating condition automatically.
Changing the settings: It may be necessary to change the
basic settings because of the conditions where the unit is
being used such as the weather or position. The electronic
controller is preset to the “coldest” setting at the factory in
order to cool the products in a range of between 2-7°C. If
need be, the cooling temperature can be set to be “warmer”.
When the night cover is opened or closed, the cabinet inte-
rior lighting is automatically switched on or off.
