Configure the summary methods for this class for either the Hourly or Daily summaries. This is a comma-delimited list of functions to use for the summary. The available functions are Average, Maximum (high-water mark), Minimum (lowest value), Standard Deviation, Median, and Total. These are abbreviated in the 'Function' argument as "Avg", "Max", "Min", StDev", Med", and "Tot". If nothing is specified, the default is "Avg,Max,StDev". You may also specify the string "None" for a summary period to disable that summary.
A null 'Function' argument will return the current summary setting in the 'Function' variable.
The 'Period' argument can be either "Hourly" or "Daily".
