8 RESET AND FACTORY SETTINGS

8.1 General system reset
To reset the system, hold down the 4 keys simultaneously for 2 sec. This operation is the same as disconnecting the
power, waiting for it to close down completely and supplying power again. The reset does not delete the settings
saved by the user.
8.2 Factory settings
The device leaves the factory with a series of preset parameters which may be changed according to the user's
requirements. Each change of the settings is automatically saved in the memory and, if desired, it is always possible
to restore the factory conditions (see Restoring the factory settings par 8.3 – Restoring the factory settings).
8.3 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 the "SET" and "+" keys and turn on the power; release the two keys only when the letters "EE" appear.
This restores the factory settings (a message and a rereading on EEPROM of the factory settings permanently saved
in the FLASH memory).
Once all the parameters have been set, the device returns to normal operation.
NOTE: Once the factory values have been restored it will be necessary to reset all the parameters that characterise
the system (gains, setpoint pressure, etc.) as at the first
