optimal. However, should any problems occur in adjustment, these settings may be varied.
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.
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 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 automatically or manu
-
ally. 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
IMPORTANT:
To obtain satisfactory pressure adjustments, you generally have to adjust
both GP and GI.
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 param
-
eters 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 subse
-
quent 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.
