With the protection active, access to all the keys is blocked, except:
‐
the “
RUN/STOP
” key: it can be pressed to stop the pump.
NOTE: pressing it again will not restart the pump, because the system will ask for the password;
‐
the navigation and menu access keys (“
ENTER”
key and “
arrow”
keys): it is possible to navigate in the menu
pages and to view the various parameters, but any attempt to change them will require you to enter the
password.
When the correct password is entered, the keys are unlocked and the parameters can be changed; the “
open padlock
”
symbol appears on the homepage (
paragraph 3.2
).
When you have finished changing the parameters, the password can be reactivated from the homepage, by selecting
the “
open padlock
” icon (
paragraph 3.2)
and pressing “
ENTER
”.
After eight hours of inactivity (without any keys being pressed), the password will be automatically reactivated anyway.
The password status is always visible, as it is represented with a special page on the homepage; see
paragraph 3.2.
The factory value of the password is “0”. See also the list of factory values in chapter 8.
If the password is lost, there are two possibilities for editing the parameters of the device:
•
Make a note of all the parameter values and reset the device the factory values (see par. 8.1). The reset
operation deletes all the device parameters, including the password, and thus re-enables the system.
•
Apply to your service centre to receive a code to unlock the device.
6.2.2 Set Points 1-4
The parameters associated with the keys from “
SET1
” to “
SET4
” can be viewed and changed under this menu item,
through the page shown on the screen.
Figure 27
The first choice to make is whether you want the setpoints “
SET1
-
4
” to set the system regulation mode to
“Flow”
or
“Speed %”
(see paragraph 5.1.1).
To do this, go to the first parameter shown at the top of the page, press “
ENTER
” and make the section with the
right
and left arrow
keys, then press “
OK
” to confirm.
This selection, which is unique for the setpoints 1-4, also modifies the setpoint units of measure, which become
respectively:
‐
in
Flow
: “
m
3
/h
” with settable values between 5 and 25 m
3
/h (or “
GPM
”, between 20 and 110 GPM),
‐
in
Speed
: “
%
” (percent), with settable values between 20% and 100%.
The units of measure and the values assigned to the setpoints (indicated with
S1 - S4
) are clearly shown on the
screen.
To change them, move with the arrows onto the value to be changed, press “
ENTER
” and change the value with the
vertical arrows; press “
OK
” to confirm the change and move on to the next values.
Each set point has its own duration, indicated on the display with the symbols
T1 - T4
and settable between 10
minutes and 18 hours, or “
ENDLESS
”.
The values
T1 - T4
are changed in the same way as described above.
The duration value indicates the time that the setpoint remains active, after which it ends; if you want the
setpoint to remain always active without interruption, the duration must be programmed as “ENDLESS”.
The factory values are given in chapter 8.
6.2.3 Set Points 5-8
This menu items allows you to view and change the parameters associated with the setpoints from 5 to 8.
