breakages of the pump.

RF: Fault and warning reset
Holding down the ^ and
˅
keys together for at least 2 seconds deletes the history of faults and warnings. The number of faults present in the log
is indicated under the symbol RF (max 8). The log can be viewed from the MONITOR menu on page FF.

PW: Change password
The device has a password-enabled protection system. If a password is set, the parameters of the device will be accessible and visible but it will
not be possible to change them.
When the password (PW) is “0” all the parameters are unlocked and can be edited.
When a password is used (value of PW different from 0) all modifications are blocked and “XXXX” is displayed on the page PW.
If the password is set it allows to navigate through all the pages, but at any attempt to edit a parameter a pop-up appears, asking you to type in
the password. When the correct password is typed in the parameters are unlocked and can be edited for 10’ after the last key is pressed. If you
want to cancel the password timer, just go to page PW and hold down ^ and
˅
together for 2”.
When the correct password is typed in a padlock is shown opening, while if the wrong password is given a flashing padlock appears.
After resetting the factory values the password is set back at “0”. Each change of the password takes effect when Mode or Set is pressed and
each subsequent change of a parameter implies typing in the new password again (e.g. the installer makes all the settings with the default PW
value = 0 and lastly sets the PW so as to be sure that the machine is already protected without any further action).
If the password is lost there are 2 possibilities for editing the parameters of the device:
•
Make a note of the values of all the parameters, reset the device with the factory values, see paragraph 9.3.
The reset operation cancels all the parameters of the device, including the password.
•
Make a note of the number present on the password page, send a mail with this number to your service centre, in a few days you will
be sent the password to unlock the device.
8.6.20.1
Password for multipump systems
When the PW is typed in to unlock a device in a set, all the devices are unlocked.
When the PW is changed on a device in a set, all the devices receive the change.
When activating protection with a PW on a device in a set (^ and
˅
on page PW when PW≠0), the protection is activated on all the devices (to
make any change you are asked for the PW).

RESET AND FACTORY SETTINGS
9.1 General system reset
To reset the system, press and hold the 4 keys simultaneously for 2 seconds. 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.
9.2 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 9.3 - Restoring the factory settings).
9.3 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.
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.
