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 set
-
tings par 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 EE
-
PROM of the factory settings permanently saved in the FLASH memory).
Once all the parameters have been set, the device returns to normal op
-
eration.
NOTE: Once the factory values have been restored it will be necessary to
reset all the parameters that characterise the system (gains, setpoint pres
-
sure, etc.) as at the first installation.

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
