5.9 SET DATA SAFEGUARD
In order to avoid set data to be modified, it is possible to block
them using the following procedure:
ih
Press and hold down at the same time, until "P1" appe-
ars on the lower part of the display. Pressing
possible to run through all the parametres:
- P1 current time
- P2 current day
- P3 regeneration time
- P4 forced regeneration
- P6 salt dosing
- P7 salt amount
- P8 hardeness in ppm CaCO
- P9 measuring system water hardness
- P10 time settings 0-12 hours / 1-24 hours
To block a set value, press the button
A lock will appear on the display.
The values can be unblocked following the same procedure.
5.10 RESIN DISINFECTION AND SALT ALARM
(MONITORING SALT PRESENCE)
On request, the water softener can be provided with an optio-
nal device that disinfects the resins during regeneration.
The device consists in a pair of electrodes that are screwed in
the valve (fig. 8) and connected to the timer connector through
a cable (fig. 6, L).
When the device is installed, the timer will manage it indepen-
dently. During the drawing water step (C2), the writing "CL"
will appear on the display.
Besides disinfecting the resins, it can also warn the user when
the brine tank has run out of salt. The orange led light under
the display will turn on (fig. 9, F, "check salt"), warning
the user to refill the brine tank with salt (fig. 7).
6) BLACKOUT AND LONG PERIODS
OF INACTIVITY
To avoid data loss during a blackout, the timer is provided
with an emergency battery that can keep data for 6 hours.
If the blackout lasts longer, it will be necessary to check the
settings.
In the event of a blackout during the regeneration cycle, the
water softener will save which step it was performing before
the interruption. When the blackout ends, the interrupted step
will be restarted and the regeneration will be completed.
7) MANUAL SETTINGS
7.1 POSTPONED REGENERATION:
Pressing the button the symbol
side of the display. This means that a regeneration will be
performed at the set time, without any modification to the
settings.
If you press the button, the command will be cancelled.
Pressing the button during regeneration, the symbol
" X2" will appear.
Also in this case, it means that a regeneration will be perfor-
med at the set time, without any modification to the program.
7.2 MANUAL REGENERATION
To start an entire regeneration cycle immediately, press and
hold down for 5 seconds.
When regeneration starts, the display will show the minutes
remaining to the end, and a "C", indicating the current rege-
neration step (fig. 20).
Regeneration is made up of 8 steps:

7.3 STEP SELECTION
To check the correct functioning of the different regeneration
steps, follow the instructions below:
1. Press and hold for 5 seconds to start a manual regene-
ration cycle.
2. Wait for a few seconds until "C1" appears on the display.
Press N if you wish to see how many minutes are left until
end of the current step.
3. Pressing the N
h
immediately skip to the following regeneration step, C2.
4. Pressing the N h
, buttons at the same time, you will im-
mediately skip to the following regeneration step, C4. This
way, you will be able to run through all the cycle steps.
To go back to working mode without going through the remai-
ning steps, press and hold the N
hour glass will appear to indicate that the camshaft is rotating.
8) ADJUSTING THE MIXER SCREW
The water softener supplies hardness-free drinking water. In
some cases, however, it can be necessary to leave a residue
of hardness in the water.
The mixer allows a chosen amount of water to pass directly
from the inlet to the outlet of the water softener, without being
softened by resins.
By loosening the mixer screw (fig. 2B, MIXER) you can gra-
dually increase the hardness of the outflowing water. Please
remember that this operation must be carried out very ca-
refully.
At the end of the operation, we suggest letting some water
flow out and measuring its hardness.
The mixer comes only with the 3/4"G joints. The 1/2"G joints
do not have a mixer included (fig. 2).
9) ANTI-SPILLOVER DEVICE (OPTIONAL)
Our softener can be fitted with an "Anti-spillover" optional
device (fig. 10).
It stops excess water from flowing into the brine tank due to
malfunctioning.
It detects excess water flowing into the brine tank, thanks
to a float that controls a mechanism that blocks water flow.
The brine level control system is a safety mechanism; con-
sequently, in case it triggers, we strongly suggest to check
its root cause.
Caution: This device only works on the connection
between the valve and the brine tank; it does not replace
the overflow device that must be installed as integral
part of our equipment (chap. 3.6).
