Parameter S1C = dir; The value HY has been preset to 2 K in the factory.
If the temperature exceeds the value SET + HY, the compressor will be
switched on and will be switched off again when the temperature is below SET.

Parameter S1C = in; The value HY has been preset to 2 K in the factory.
If the temperature falls below the value SET-HY, the controller output will be
switched on and will be switched off again when SET is exceeded.
