System displays 'No file' means its an SD card error which is caused by a corrupt SD card
Please reboot the system to refresh the controller.
You
can also try and take the controller of the wall, take the SD card out
and wipe the SD card and the controller with a lint free cloth. Put it
back in and re attach the controller to the wall and then do a 'forced'
system reboot.
Do this by holding in the power button 3-5 seconds and the screen blacks out and reboots the controller
If fault still persists please run through the steps above again
You can also try and take the controller of the wall,
- To remove the controller fascia cover it is
recommended to place pressure on the controller above the up button whilst
attempting to remove the cover at either the top or the bottom, never in the
middle. This will enable the cover to be removed whilst the controller remains
in place without damaging the controller fixings or wall. The controller then
needs to be removed from the wall.
- Once the SD card has been removed and clean it with a lint free cloth,
the blue data cable at the rear of the controller must be unplugged fully, and
then reconnected before the SD card is reinserted. This enables the system to
perform a reboot. Note the use of a hard reset by pressing and holding the
power button for three seconds doesn’t enable a full reboot, and this is why
the data cable must be unplugged.
If the fault doesn't clear after the second time, please reply to you case email and update us.
We will have to book in a customer service technician to come out and update the controller / SD card (fees apply).
