Liebherr SmartMonitoring is a comprehensive solution for documenting and monitoring measurement and operating data, alarm messages and device states. The SmartCoolingHub required for this can be directly connected to this device via the available RS 485 interface. The alarm testing allows you to check whether the alarm system is functioning properly (no matter if it is internal or external). The test has no effect on the performance of the refrigerator. The inside temperature shown on the digital display is rounded to the nearest degree and can be easily read from the outside. This eliminates the need to open the appliance. Highly efficient fans cool down freshly inserted food quickly and keep the temperature constant throughout the interior. Liebherr has been accumulating experience and research and development in the field of cooling for decades, guaranteeing the highest quality equipment refrigeration. By using only first-class compressors, condensers, evaporators and other cooling system components, Liebherr creates energy-saving devices with low operating costs. The cooling system components are built into the top of the unit and are therefore easily accessible. The cover of the compressor compartment on the hinged upward hinge can be easily opened, which makes cleaning and maintenance much easier without the need to move the appliance, as the condenser filter located behind the compartment cover is easily accessible.
