Hi all,

Calls to the History API have a bunch of degree day-related entries. Can someone please tell me what the base temperature is that is used for the degree days values? If possible, I'd also like to know the methodology you are using for calculating the DD values.

Thanks!

Examples are:
&ltheatingdegreedays&gt26&ltheatingdegreedays&gt
&ltcoolingdegreedays&gt0&lt/coolingdegreedays&gt
&ltheatingdegreedaysnormal/&gt&ltmonthtodateheatingdegreedays/&gt
&ltmonthtodateheatingdegreedaysnormal/&gt&ltsince1sepheatingdegreedays/&gt
&ltsince1sepheatingdegreedaysnormal/&gt&ltsince1julheatingdegreedays/&gt
&ltsince1julheatingdegreedaysnormal/&gt&ltcoolingdegreedaysnormal/&gt
