The outside temperature
➊ for the commutation from summer to winter
operation is decisive for the drycooler and compressor control. With this
hysteresis
➋ the winter operation changes to summer operation.
The winter operation is also switched over to summer operation, if an out-
side temp. sensor breakdown is detected. An alarm "Outside temperature
sensor defective" is not displayed.
If no outside temperature sensor is configured, summer operation is
active.
