Parameter levels: Standard level and advanced level
The setting menu is divided into two distinct function areas, the standard level and the advanced level.
The standard level comprises parameters P00 to P09. In this area, all standard actual values can be
displayed and the basic set value for the controller can be set. Parameter P09 can trigger a manual
defrost if required.
The advanced level comprises both parameters P00 to P09 and also parameters P10 to P70. In this
area, all control, defrost, fan, compressor and probe parameters can be displayed and set.
