All these can be set in the NOAA Setup Screen in Configuration menu. You might select to close Cumulus, and edit the 'NormNOAATempNorm[Jan-Dec]' and 'NOAARainNorm[Jan-Dec]' parameters by using a external editor to manipulate into required format, copy, and paste, the values from another source (as there are a lot of figures to type in).

|The base temperature which is to be used to calculate heating demand as [[Heat/cold degree days and Chill hours | heating degree days]]. The default is 65 degrees Fahrenheitif thatyou equatesuse toFahrenheit 18scale 1/or 18.3 degrees if you use Celsius. The value you type on the NOAA Setup Screen is entered in the units that you have selected for temperature. Degree days are calculated on a minute-by-minute basis and the totals for each day are stored in dayfile.txt. Changes to the threshold values cannot therefore apply retrospectively. But, if the dayfile.txt entry doesn't have the degree days in it, then it uses the day's average temperature to produce a 'simplified' heating or cooling degree days figure (but obviously never both at the same time) and in that case it does use the current threshold settings.
