General 

The MBAC can control a refrigerator. Control of the refrigerator is a basic function of the MB Advanced Control, control unit (N175).

The MBAC is equipped with the following interfaces for control:

• LIN interface
• I/O interface

LIN interface 

The MBAC can adjust the mode (OFF, automatic, gas, 12 V or 230 V) of each refrigerator. To do this, the refrigerator must be connected to the MBAC over the LIN interface and must be able to be controlled.

The MBAC allows the user to adjust the mode (OFF, automatic, gas, 12 V or 230 V) of each refrigerator. To do this, the refrigerator must be connected to the MBAC over the LIN interface and must be able to be controlled.

The MBAC can adjust the cooling stage (stage 1, stage 2, stage 3, stage 4 or stage 5) of each refrigerator. To do this, the refrigerator must be connected to the MBAC over the LIN interface and must be able to be controlled.

The MBAC enables each user to adjust the cooling stage (stage 1, stage 2, stage 3, stage 4 or stage 5) of each refrigerator. To do this, the refrigerator must be connected to the MBAC over the LIN interface and must be able to be controlled.

The MBAC can adjust the freezing stage (stage 1, stage 2, stage 3, stage 4 or stage 5) of each refrigerator. To do this, the refrigerator must be connected to the MBAC over the LIN interface and must be able to be controlled.

The MBAC enables each user to adjust the freezing stage (stage 1, stage 2, stage 3, stage 4 or stage 5) for each refrigerator. To do this, the refrigerator must be connected to the MBAC over the LIN interface and must be able to be controlled.

I/O interface 

The MBAC can control the state of a refrigerator pump (switched on or switched off). For this, the refrigerator pump must be connected to the interface "DO_Performance_Refrigerator box_Pump" and must be able to be controlled.
