1 – INTRODUCTION
Aqua Cubic Multiplex is a controller dedicated to the realisation of water softening systems working on the
principle of the ionic exchange of the resins.
The systems can be produced according to the following operative modalities:
- one single column;- one duplex column;
- two alternated single columns;- two single columns in parallel;
three single columns;
Aqua Cubic Multiplex automatically calculates the volume of water which can be treated based on the
hardness of the water, on the volume of the tanks and on the exchange capacity of the resins used, values
which must be programmed by the operator when the appliance is installed.
It is also possible to programme a percentage of reserve of the total volume, which allows for the
regeneration of the resins to be started before they have completely run out.
Aqua Cubic Multiplex allows for columns with different dimensional characteristics to be controlled,
that is with different volume values, also allowing the differentiation of the regeneration cycle times.
The regeneration cycle is completely programmable: it can be started up by the control on the volume,
manually, or by an external signal, it is possible to cancel the whole cycle or to jump one or more phases.
The regeneration may be immediate or deferred to a programmed time.
Aqua Cubic Multiplex may be connected to a computer via RS232 using the cable cod. 881-1, so as to be
able to acquire and then analyse the progress of the work parameters
Aqua Cubic Multiplex is equipped with a buffer battery which allows for the work parameters to be
retained in the memory should the electricity current fail.
Aqua Cubic Multiplex is equipped with an EEPROM memory, on which the programmed data is
memorised, with the capacity to retain data for over 10 years.
Aqua Cubic Multiplex, like all the range of SIATA controllers, conforms to the EEC Directives and is
produced in the SIATA plant of Montespertoli which operates with the certified Quality System according to
the regulation
ISO 9001 / UNI EN ISO 9001.

5 – GENERAL
The installation of the controller must be carried out by qualified personnel; the installation procedures must be carried
out when the controller is disconnected from the electricity supply
5.1 – Packaging and storage
The packaging consists of a cardboard box with a label identifying the product, carrying the following information:
name of producer and PN producer AC-MULT2/05; the quick reference guide for the installation and programming
may be found inside.
No particular procedures are necessary for the removal of the controller from the packaging.
The controller must be stored in environments with the following characteristics:
• Temperature of between +0°C and +55°C;
• Relative humidity of between 30 % and 95 %.
5.2 – Installation
The appliance consists of a PVC box with a cover in plexi-glass which may be opened manually, giving access to the
keypad, and of a cover which may be removed by loosening two screws and which gives access to the external
connection terminal board.
The box is covered by a certificate with the IP65 grade of protection, Aqua Cubic Multiplex is therefore protected
against infiltration of dust and direct jets of water. This protection is valid when the cover is closed, and the wiring slots
are of the correct size for the cables used and are correctly assembled. If these conditions are not respected, the level of
protection falls to IP40, which gives no protection against infiltration of dust and water.
The back of the box is equipped with mechanical details which allow it to be wall-mounted.
5.3 – Electrical connections
The electrical connection of the controller must take place conforming to the conditions stated in the diagram CE0024
shown on the attached page.
The appliance is equipped with free contact exits with the following signals.
- Dosage pump
- A in service
- B in service
- C in service
- Alarm
Warning!!
Before carrying out any installation and/or maintenance operation, check that the controller is disconnected from the
electricity supply.
5.4 – Protection devices
The appliance is protected from current overloads by a 0.6A supply retardant fuse which is assembled on the front
panel. It is also protected against disturbances originating from the electricity supply by filters mounted inside the
controller.

Aqua Cubic Multiplex - MAN0004 Rev. B 29.03.99 9/33
6 – INSTRUCTIONS FOR USE
6.1 – Turning on
The appliance is turned on via the main switch ON (I) - OFF (0) situated on the front panel. This switch acts on both
supply cables
The supply voltage must be 24 Vac - 50 Hz. (on demand 24 vac – 50 Hz. )
Check the supply voltage using the adhesive labels situated on the cover of the connections.
6.2 – Programming of the operative modalities
Before proceeding to the programming of Aqua Cubic Multiplex, it must be checked that the distributor cams are
positioned at the stroke end and that any unused limit switch entries on the terminal are closed with a connector
bridge. If this simple rule is not respected, Aqua Cubic Multiplex cannot enter into service and access to the keypad
will be limited after a few operations.
The programming will be carried out via the keypad on the front of the appliance.
Aqua Cubic Multiplex Plus has the following operative modalities:

Aqua Cubic Multiplex - MAN0004 Rev. B 29.03.99 10/33
6.2.1 – PPP0 – One single column
6.2.1.a – Operative characteristics.
This operative modality has been provided to resolve situations of emergency; Aqua Cubic Multiplex allows for the
use of a distributor connected to a valve to ensure the supply of treated water to the utiliser when breakdowns of any
degree of gravity do not allow the system to work fully and properly ( see par. 7.5 for details ).
The distributor must be connected to the terminals of the column A.
When the column is in service, the LED A Service will come on on the panel and the relative signal on the pins 43 – 44
of the terminal board will be active. The LED Awill be on, to confirm the fact that the display is visualising the
parameters of that column. As soon as the controller is in the position of waiting for the regeneration time, for example
because the volume has run out, the signal on the terminal board will go out, while the LED A Service will remain on
on the panel. As soon as the regeneration cycle starts, the signal on the terminal board will remain off, while on the
panel, the LED A Service will go out, and the LED Regeneration will come on.
The display will show the progression of the regeneration cycle.
The start of the regeneration cycle is controlled by the flags 0HP, 1HP, 2HP and 0dP.
To know how the controller reacts to the events, consult tab. 6. In the column Programming find the sequence of
values which corresponds to that programmed on the controller, and so, on the basis of the events, the manner in which
the controller will react may be seen.

N.B. :
(1) The expression “when the days have run out” is substituted with the expression “on the active days” when the flag
1HP is at 1. In fact, in these cases, the interval days between two regenerations are not programmed, but the active
days of the week on which the regeneration cycle is required.
(2) The start of the cycle is immediate if, at the moment of the activation of the remote Start signal, the controller is in
service. If, on the other hand, it is waiting for the regeneration time because the volume has run out, and the

Aqua Cubic Multiplex - MAN0004 Rev. B 29.03.99 11/33
controller is therefore not in service, the remote start signal is ignored and the regeneration will be carried out at the
programmed time.
(3) The expression “The reg. starts at the time” means that the cycle starts at the programmed time even if the
programmed interval days have not passed or if it is not an active day for the start of the regeneration cycle.

At the end of the programming the code 220 must always be keyed in (see par. 6.3) to initialise Aqua Cubic Multiplex
with the new parameters.
Note that the control on the reserve (flag 0dP) is automatically active and cannot be dis-activated.
6.2.1.c – List of codes to be programmed
For the programming and the meaning of the codes, see par. 6.3. In this modality, the programming of the following
codes is recommended:
Tab. 8 – Table of the codes recommended in the modality “one single column, PPP0”
Code Meaning
011 Programming of the value of the exchange capacity of the resins
012 Programming of the regenration time and the interval days between two regenerations
020 Programming of the time and day of the week
100 Programming of the volume of resin and of the percentage of reserve of the column A
110 Programming of the litre counter divider ( prescaler )
112 Programming of the regeneration cycle ( stop times )
010 Programming of the hardness value
220 Initialisation of the system
6.2.2 – PPP1 – Three single columns.
6.2.2.a – Operative characteristics.
This operative modality allows for the use of three distributors each of which is connected to a single SIATA valve.
The three columns alternate in service, so that while two are in service, the third will be first in regeneration and
then in stand-by.
When the controller is put into service, typically after having keyed in the 220, the column C is put into stand-by, while
the columns A and B are put into service. The signals to the pins 43 – 44 and 45 – 46 of the terminal board will be
active, respectively for the column A and the column B, while the pins 47 – 48 for the column C will be inactive. The
LEDs A Service and B Service on the panel will be on, while the LED C Service will be off.
The LED Awill be on to indicate that the display is visualising the volume of the column A.
With the key 2/+ it is possible to change the column visualised on the display. Each time the key is pressed, the LEDs
A, Bor Cwill come on when the data of the relative column is transferred to the display. If the column visualised is in
service it is possible to read the residual volume. If it is in regeneration it is possible to follow the progression. If it is in
stand-by, the display will show four lines.
When one of the columns in service goes into in regeneration by finished volume, the column in stand-by will go into
service in place of the column which has just run out. The LEDs on the panel will come on to indicate the new situation.
The LED Regeneration will be on for the whole duration of the regeneration cycle. The signals to the pins of the
terminal board mentioned above will also activate in accordance with the new situation.
This operative modality is not programmable. As seen in tab. 9, any programming of the flags always takes place in the
same way.
When one column finishes the available volume, the controller immediately enters into regeneration, and the column in
stand-by enters into service. If both of the columns in service have a residual volume of less than the calculated reserve,
the controller will start up a regeneration immediately for the column which in that moment has the lowest volume. The
control on the reserve cannot be disactivated. If this control is not required, the effects can be minimised by

Aqua Cubic Multiplex - MAN0004 Rev. B 29.03.99 13/33
programming the percentage of reserve at the minimum value of 10%.

N.B. :
1) The start of the cycle is immediate only when both of the columns in service have a volume below the value of
reserve. The column which has the lowest volume out of the two starts in regeneration. If only one of the columns
reaches the value of reserve, the regeneration does not start, even at the programmed time.

the cycle times of the column B is required, (the columns A and C use the same times, programmed with the code 112),
it is necessary to add to the list of tab. 11, the code 111, and the flag 1CP must be programmed with the value 1.
In the case in which columns of different dimensions are used, the recommended programming varies as follows:
Tab. 12 – Table of the codes recommended in the modality “three alternated single columns, PPP1” of different
dimensions
Code Meaning
011 Programming of the value of the capacity of resins exchange
020 Programming of the time and of the day of the week (non influential)
100 Programming of the volume of resin and of the percentage of reserve of the column A
101 Programming of the volume of resin and of the percentage of reserve of the column B
102 Programming of the volume of resin and of the percentage of reserve of the column C
110 Programming of the litre counter divider (prescaler)
111 Programming of the regeneration cycle ( stop times ) per the column B
112 Programming of the regeneration cycle ( stop times ) for the columns Aand C
010 Programming of the hardness value
220 Initialisation of the system
Remember that in order to use Aqua Cubic Multiplex as described in tab. 12, the flag 1CP must be programmed to 1.
6.2.3 – PPP2 – Two alternated single columns.
6.2.3.a – Operative characteristics.
This operative modality allows for the use of two distributors, each of which connected to a single SIATA valve.
The two columns alternate in service, and so while one is in service, the other will be first in regeneration and then
in stand-by.
As soon as it is put into service, typically after having keyed in the code 220, the column B is put into stand-by, while
the column A is put into service. The signal to the pins 43 – 44 of the terminal board will be active, while the signal to
the pins 45 – 46 for the column B will be inactive. The LED A Service on the panel will be on, while the LED B
Service will be off. The LED Awill be on to indicate that the display is visualising the volume of the column A.

Aqua Cubic Multiplex - MAN0004 Rev. B 29.03.99 16/33
With the key 2/+ it is possible to change the column visualised on the display. Each time the key is pressed, the LEDs A
or Bwill come on when the data of the relative column is transferred to the display. Se the column visualised is in
service the residual volume can be read. If it is in regeneration, the progression can be followed. If it is in stand-by, the
display will show four lines.
When the column in service goes into regeneration by finished volume, the column in stand-by will go into service in
place of the column which has just run out. The LEDs on the panel will come on to indicate a new situation. The LED
Regeneration will be on for the whole duration of the regeneration cycle. The signals to the pins of the terminal board
shown above will also activate in line with the new situation.
This operative modality is not programmable. As may be seen in tab. 13, any programming of the flags always brings
on the same result.
When one column finishes the available volume, the controller immediately enters into regeneration, and the column in
stand-by enters into service. There is no control either on the reserve or on the remote start.

Remember that in order to use Aqua Cubic Multiplex as described in tab. 16, the flag 1CP must be programmed to 1.
6.2.4 – PPP4 – One duplex column.
6.2.4.a – Operative characteristics.
In this modality a single distributor connected to 2 SIATA valves is used. The distributor is connected to the
terminals of the column A.
This distributor has a special cam, modified so as to divide the 360º of rotation between the two valves; the first 180º
are dedicated to column A, the second to column B. Normally defined as column A is the valve connected to the pilots
1 and 2, those nearest to the distributor, and defined column B is the valve connected to the pilots 3 and 4 ( see also the
connections indicated in the attached page C).
Which of the two columns is active, and therefore which valve is in use, depends only on the position of the cam of the
distributor. The controller cannot know which column is in service. In fact, as will be shown, both the optical and
electrical signals will always communicate that column A is in service.
Suppose the following operations are to be carried out when the distributor has the cam in the stroke end position at the
beginning of the first 180º of rotation, that is so as to have the valve A in service. After having keyed in the code 220,
the controller will begin with the valve A in service. The signal to the pins 43 – 44 of the terminal board will be active.
The LED A Service on the panel will be on. The LED Awill be on to indicate that the display is visualising the volume
of the column A.

Aqua Cubic Multiplex - MAN0004 Rev. B 29.03.99 19/33
The key 2/+, which normally allows for the column visualised on the display to be changed, cannot be used until a
regeneration starts. Normally the display shows the parameters of the column in service, indicating that they belong to
the column A. Having positioned the distributor so as to have the valve A in service, the parameters visualised are in
fact those of the column A. As soon as this valve enters into regeneration, regeneration, the signal to the pins 43 – 44
goes out and the rotation of the cam causes valve B to be put into service. The display visualises the progression of the
regeneration cycle.
Now pressing the key 2/+ it is possible to visualise the residual volume of the column as soon as it has entered into in
service, that is the volume of the valve B. Note that the LED Astill remains on.
As soon as the regeneration terminates, the LEDs on the panel will indicate again that the column A is in service and
that its parameters are being visualised. In reality, the display is showing the parameters of the valve B, those which,
during the regeneration cycle, it was possible to see only with the key 2/+. When the valve B has run out of volume and
starts the regeneration, the operations just described will be repeated and the parameters of valve A will be visualised
again.
To summarise:
1- the controller always indicates that the column A is in service;
2- the signal to the pins 43 – 44 of the terminal board goes off during the regeneration, so this signal cannot be used
for an electrical column exchange;
3- which valve is actually in service depends only on the position of the cam of the distributor;
4- during the regeneration, pressing the key 2/+ it is possible to visualise the volume of the column which has taken
over in service.
This operative modality is not programmable. As shown in tab. 17, any programming of the flags always brings on the
same result.
When one column finishes the available volume, the controller immediately enters into regeneration. The rotation of the
cam controls the exchange of the columns, so the stand-by valve enters into service.
