• transfer of status data files (type *.txt) and setting files (type *.set) from
the R100 to the PC.
When the status data files have been transferred to the PC via the USB con-

5.1 Programming the R100

If "Unknown product" appears in the R100 display during communication
with a product, the R100 must be upgraded with a new application software
version. To get the new software, please contact Grundfos.

1. Switch off the R100.
2. Connect the R100 to the PC via the USB cable.
3. Press all four arrow buttons and
be switched on and open in "Programming mode" showing the message
"USB link established". In a Windows browser, it will appear as
"Removable Disk" and the application program file (type *.mk2) will
appear.

display during the deletion, which takes 30 seconds. After the deletion,
"USB link established" appears in the R100 display.
5. Copy the new application program file to "Removable Disk". "Device
busy" appears in the R100 display during the file transfer, which takes
approximately 50 seconds. After the file transfer, "Device safe to remove"
appears in the R100 display.
6. Perform a safe removal of the R100 USB connection.
