15 DATA LOG MENU
The data log saves machine operating conditions, temperature setting, ambient temperature, set-point in use, water-
related measurements (pressure and flow, as well as pH and conductivity, if implemented), ventilation data, output
status, current alarms, and main configuration parameters. The data is saved every 30 minutes and when an alarm is
triggered or resolved.
The LU1W controller memory has a capacity of approximately 5 years of operation, after which the data is overwritten
starting from the oldest.
You can download the data log to a USB stick, 4GB maximum recommended size.
Insert it into the controller's USB port, enter the DATALOG menu; the cursor is positioned at the CSV Print entry. Press
the ENTER key, change the parameter to Yes, and press the ENTER key again to confirm. The data log status then
switches to OK STOP. After a few seconds, the CSV Print parameter automatically returns to No, and the Status returns
to OK Run.
The controller saves a .csv file called DryWetCooler_AAAA_MM_GG (AAAA = year, MM = month, GG = day download)
in the root of the USB key.
