Caravan Control Unit Refrigerator Status, Function - GF54.21-D-5042TSA

Model 907 

with code JA3 (Intelligent body control.) 

General 

The refrigerator status request is a basic function of the MB Advanced Control control unit (N175).

The MBAC has the following interfaces to read out various refrigerator states:

LIN interface 

The MBAC can read out the current mode (OFF, Automatic, Gas, 12 V or 230 V) of each refrigerator. To do so, a refrigerator must be connected over the LIN interface to the MBAC and be controllable.

The MBAC enables the user to read out the current mode (OFF, Automatic, Gas, 12 V or 230 V) of each refrigerator. To do so, a refrigerator must be connected over the LIN interface to the MBAC and be controllable.

The MBAC can read out the current cooling stage (Stage 1, stage 2, stage 3, stage 4 or stage 5) of each refrigerator. To do so, a refrigerator must be connected over the LIN interface to the MBAC and be controllable.

The MBAC enables the user to read out the current cooling stage (Stage 1, stage 2, stage 3, stage 4 or stage 5) for each refrigerator. To do so, a refrigerator must be connected over the LIN interface to the MBAC and be controllable.

The MBAC can read out the current freezing stage (Stage 1, stage 2, stage 3, stage 4 or stage 5) of each refrigerator. To do so, a refrigerator must be connected over the LIN interface to the MBAC and be controllable.

The MBAC enables the user to read out the current freezing stage (Stage 1, stage 2, stage 3, stage 4 or stage 5) for each refrigerator. To do so, a refrigerator must be connected over the LIN interface to the MBAC and be controllable.

I/O interface 

The MBAC can read out the current temperature of the refrigerator between 2 threshold values with a specific resolution in °C. To do so, a refrigerator temperature sensor must be connected to the "AI_Refrigerator_Box_TempSensor" interface and be controllable.
