5.6.4 - GI: Integral gain coefficient

In the presence of large falls in pressure due to a sudden increase of the flow or a slow response of the system, increase the value of GI. Instead,
if there are swings in pressure around the setpoint value, decrease the value of GI.
IMPORTANT: To obtain satisfactory pressure adjustments, you generally have to adjust both GP and GI.

5.6.5 - RM: Maximum speed

Sets a maximum limit on the number of pump revolutions.

5.6.6 - AY: Anti Cycling

As described in paragraph 9, this function is for avoiding frequent switching on and off in the case of leaks in the system. The function can be enabled
in 2 different modes, normal and smart. In normal mode the electronic 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 inactivity; it acts by periodically rotating the pump.
When the function is enabled, every 23 hours the pump performs an unblocking 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 temperature reaches values close to freezing point, in order to avoid
breakages of the pump.

5.7- Setting low pressure detection on suction (typically used in boosting systemsconnected 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 automatically 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 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. Depending 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.
In the case of blockage due to water lack (BL), blockage due to motor overload (OC), blockage due to direct short circuit between the motor
phases (SC), you can try to exit the error conditions manually by simultaneously pressing and releasing the ˄ and ˅ keys. If the error condition
remains, you must take steps to eliminate the cause of the fault.
In the event of blocking due to one of the internal errors E18, E19, E20, E21 it is necessary to wait 15 minutes with the machine powered until the
blocked status is automatically reset.
