5.1 READING OF PROGRAMMED DATA
–
By pressing the button the letter 'M' will be displayed
alternating with the minutes of the current time.
+
Pressing the key will display the 'U' values display in se-
quence.
The value 'U0' indicates the model of the softener (5, 8 or
12 litres).
The subsequent 'U' values display show the parameters ente-
red during programming (tab.3).
5.2 REGENERATION BUTTON
The button allows you to carry out a regeneration manually
(fig.3, O).
- By pressing it at any time for 2 seconds, a dot will appear
in the lower right part of the display to indicate that the
softener will perform a regeneration when the time as pro-
grammed is reached (chap.5 tab.n.3, P3 and P4).
- By pressing it for at least 4 seconds, regeneration will take
place immediately.
5.2.1 CONNECTION TO EXTERNAL EQUIPMENT
The GAE water softener can be connected to a machine or
external equipment via the button cable fig.3,O.
In this case the external machine will be able to carry out
regenerations independently of the softener programme.
- By closing the contact, at any time for 2 seconds, a dot will
appear in the lower right part of the display to indicate that
the softener will perform a regeneration when the time is
reached as programmed (chapter 5 tab.n.3, P3 and P4 ).
- By closing the contact for at least 4 seconds, regeneration
will take place immediately.
N.B. The command closes the connection cable circuit
(free contact).
5.3 SALT ALARM (FIG. 4, A)
(MONITORING OF THE PRESENCE OF SALT IN
THE BRINE TANK)
The softener is equipped with a device (fig. 11, A) which,
when in contact with the water coming from the brine, is able
to detect the presence of salt.
If the device does not find salt in the water, both a visual and
audible signal will be given, to warn the user to refill the salt
in the brine tank.
This monitoring is carried out during regeneration, at the be-
ginning of phase b5.
5.3.1 SALT CONTROL WARNING (FIG. 4, B)
The water softener with salt control will remind us to check
the presence of salt in the brine tank after having carried out a
set number of regenerations.
To program this function, you must set the number 1 to pa-
rameter A1 and enter how many regenerations must be per-
formed before emitting the acoustic signal at parameter A3.
The alarm will be signalled by a fixed red LED and an intermit-
tent acoustic signal.
5.3.2 SALT ALARM / SALT CONTROL
- By fully activating the salt monitoring, the water softener will
signal the absence of salt in two ways:
• With the red LED flashing (fig. 10, C).
• With intermittent acoustic signal.
This device works from 8 am to 12 pm and from 2 pm to 6
pm. For 3 minutes it will emit an acoustic signal and for 7
minutes it will be silent.
- By setting parameter A2 to 0, the softener will signal the
absence of salt only visually via the flashing red LED (fig. 10,
Instruction Manual GAE
C).
5.3.3 SILENCE THE SALT ALARM/SALT CONTROL
When the water softener shows the writing "AS", it is in "salt
alarm". To silence the alarm, press the R button twice.
Check the presence of salt and add to the brine tank if ne-
cessary.
When the water softener displays the writing "CS" (salt con-
trol) and simultaneously emits an acoustic signal, the correct
procedure to silence the alarm will be:
- press the button twice.
R
Load the necessary quantity of salt into the brine tank to carry
out all the set regenerations.
For example: if you are loading salt into the brine of a GAE8
model which requires one kg. of salt for regeneration and it is
shown that the next check will take place between 10 regene-
rations, it will be necessary to load at least 10 kg of salt into
the brine tank (see tab.3, A3) (see chapter 5).
6) BLACKOUT AND LONG PERIODS
OF INACTIVITY
If a blackout occurs, it will not cause any problem to the water
softener. Even if the blackout lasts a few days the softener is
able to store the data. If the blackout is longer than 15 days,
we recommend checking all the settings, day and time inclu-
ded. In the event of a blackout during the regeneration cycle,
the water softener will save which step it was performing
before the interruption. Once power is back, the step it was in
at the time of the blackout will start again.
If the water softener is non-operational for a few days,
once power is back, the step it was in at the time of the
blackout will start again (par.7.1).
7) MANUAL SETTINGS
7.1 MANUAL REGENERATION
To perform a manual regeneration, press and hold the
for 4 seconds. During the regeneration, the display will show
the current step and the time left until completion. The phases
follow one after the other until the valve returns to normal
exercise position. To skip to the next step, press and hold the
key for 2 seconds.
R
The regeneration is made of the following 4 phases:
b1 Service mode: the machine is operational. Water from
the system comes in and softened water comes out.
b3 Backwash: it is the quick rinse phase. Water flows in
the tank backwash, mixing and rinsing the resins and
carrying to the drain any impurities that may have formed
in the water softener during its work.
b5 Brine sucking and slow rinse: during the first part,
salty water is sucked and sent in contact with the resins,
together with the hypochlorite produced by the electro-
des (fig. 11, A). At the end of this phase, a slow resin
rinse is performed.
b7 Refill and quick wash: water is sent to the brine tank in
order to melt the correct amount of salt that will be used
in the next regeneration. At the same time, a resin rinse
is performed.
During steps b3, b5 and b7 the water softener will send water
to the drain. When the machine is in service mode b1, the wa-
ter softener does not send water to the drain. Water is always
supplied during regeneration.
See CHART 2, paragraph 5 for the duration of every step.
7.2 DELAYED MANUAL REGENERATION
