Restoring the factory settings
To reset the factory values, use the "Factory Settings" page of the "System" menu (par. 6.2.10).
Alternatively, switch off the device, wait until the display has switched off completely, press and hold down simultaneously the two keys "SET1"
and "SET4" and turn on the power; release the keys only when the messages appear on the display. This restores the factory settings (consisting
of a message and a rereading on EEPROM of the factory settings permanently saved in the FLASH memory and listed in the table above).
Once all the parameters have been set, the device returns to normal operation.
NOTE: this operation obviously deletes all the parameters that have previously been modified by the operator. Once the factory
values have been restored, it will therefore be necessary to reset all the parameters that characterise the system, as at the first
installation: for the sake of convenience, the system again proposes the WIZARD (paragraph 4.2).
