into the 03478 IPUII SD card slot to record the chiller
operating parameters at 5 second intervals. The data
is stored in a folder named RMYYYYMM where
YYYY is the year and MM is the month the data was
recorded. The controller creates a file for each day
within this folder with the format YYYYMMDD.
