The data are valid for the period between the current request and the previous request. The maximum range of a period is
1 hour. Recalling the average value of a minimum, maximum and average group will erase the appropriate registers.
Retrieve the values of a group in the sequence minimum, maximum, average.
Use command: 0x03
