ated with software version V3.xx and higher.

The controller is equipped with a data logger which records
the data of the heat pump for a period of 48 hours (temper-
atures, inputs/outputs). You can save this data to a USB stick.
To do so, insert the USB stick into the controller and use
the menu item data logger to save the data to the USB stick.
An authorised customer service or tter can start a perma-
nent data logger function using his or her password access.
If the USB stick is inserted, the data including date and time
will then be stored automatically every 48 hours.
NOTICE
Please remember to save the data logger to the
USB stick before removing the USB stick from the
control element. You will otherwise lose the most
recent values.
