When a USB memory is connected a new menu (menu

Menu 7.1 - update firmware
update firmware7.1
start updating
choose another file
This allows you to update the software in VVM 320.
NOTE
For the following functions to work the USB
memory must contain files with software for
VVM 320 from NIBE.
The fact box at the top of the display shows information
(always in English) of the most probable update that the
update software has selected form the USB memory.
This information states which product the software is
intended for, the software version and general informa-
tion about them. If you wish to select another file than
the one selected, the correct file can be selected by
"choose another file".
start updating
Select “start updating" if you want to start the update.
You are asked whether you really want to update the
software. Respond "yes" to continue or "no" to undo.
If you responded"yes" to the previous question the up-
date starts and you can now follow the progress of the
update on the display. When the update is complete
VVM 320 restarts.
TIP
A software update does not reset the menu
settings in VVM 320.
Caution
If the update is interrupted before it is com-
plete (for example power cut etc.), the soft-
ware can be reset to the previous version if
the OK button is held in during start up until
the green lamp starts to illuminate (takes about
10 seconds).
choose another file
Select “choose another file" if you do not want to use
the suggested software. When you scroll through the
files, information about the marked software is shown
in a fact box just as before. When you have selected a
file with the OK button you will return to the previous
page (menu 7.1) where you can choose to start the up-
date.
