==== GrowingDegreeDaysReferenceTemp ====
This parameter contains the reference temperature for the chart Growing Degree Days and represents the heuristic temperature at which plants come out of their winter rest. In principle the chart ''Temperature Sum'' has a non modifiable ''reference temperature'' of 0.
==== WinterToSpringTemperatureLimit ====
With a default of zero degrees Celsius this parameter defines the thermal boundary between winter and spring.
If 10 successive days have an average temperature above 0 °C then Spring is declared. The same boundary works the other way around to declare transition from autumn to winter.
==== SpringToSummerTemperatureLimit ====
With a default of 10 °C this parameter defines the thermal boundary between spring and summer.
If 10 successive days have an average temperature above 10 °C then Summer is declared. The same boundary works the other way around to declare transition from summer to autumn.
