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 al-
ways 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 EE-
PROM 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

7.10.1 - Password for multipump systems
The PW parameter is one of the sensitive parameters, so for the device
to work it is necessary for PW to be the same for all the devices. If there
is already a chain with an aligned PW and a device is added with PW=0,
the request to align the parameters will be made. In these conditions the

The key represents a coding of the password. Depending on the cor-

chain can be aligned.
