8.1 Restoring the factory settings
To restore the factory values, 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).
