7. RESET AND FACTORY SETTINGS
7.1 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.
7.2 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 7.3 - Restoring the factory settings).
7.3 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 installation.
