Software update
NOTE
New software may be uploaded to the controller only by a qualified fitter. After the
software is changed, it is not possible to restore the previous settings.
To upload new software, the controller should be disconnected from the power supply. A flash
drive with the new software should be inserted to the USB port. Then, the user should connect
the controller to the power supply while holding the EXIT button. The user should hold the EXIT
button until a single acoustic signal is heard – this means that the new software is being uploaded.
After the task is completed, the controller will restart by itself.
CAUTION
Never switch the controller off when the software is being updated.
