tronic control blocks the motor after N identical start/stop cycles. In smart
mode it acts on the parameter RP to reduce the negative effects due to
leaks. If set on "Disable", the function does not intervene.
5.6.7 - AE: Enabling the anti-block function
This function is for avoiding mechanical blocks in the case of long inactiv-
ity; it acts by periodically rotating the pump.
When the function is enabled, every 23 hours the pump performs an un-
blocking cycle lasting 1 min.
5.6.8 - AF: Enabling the anti-freeze function
If this function is enabled the pump is automatically rotated when the tem-
perature reaches values close to freezing point, in order to avoid break-
ages of the pump.
5.7- Setting low pressure detection on suction (typically used in
boosting systems connected to the water mains)
Present only in models with Kiwa function.
The low pressure detecting function generates the blocking of the system
after the time T1 (see 5.5.6 - T1: Low pressure delay).
When this function is active the symbol F4 is shown on the main page.
Tripping of this function causes the pump to cut out; it may be reset auto-
matically or manually. The automatic reset requires that, to leave the error
condition F4, the pressure must return to a value 0.3 bar higher than PK
for at least 2 sec.
To reset the cut-out in manual mode, press and then release the "+" and
"-" keys simultaneously
5.8 - 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 64).
The log can be viewed from the MONITOR menu on page FF.
5.8.1 - 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
61
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 7.3. 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.

6 - PROTECTION SYSTEMS

The device is equipped with protection systems to preserve the pump, the
motor, the supply line and the inverter. If one or more protections trip, the
one with the highest priority is immediately notified on the display. Depend-
ing on the type of error the motor may stop, but when normal conditions
are restored the error status may be cancelled immediately or only after a
certain time, following an automatic reset.
