Aqua Cubic Plus - 5/27
1 – INTRODUCTION
Aqua Cubic Plus 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;
In the modality two alternated single columns it is possible to activate the function Modular, which
consists of putting into service the stand-by column when the instantaneous load in litres/minutes
absorbed by the utiliser exceeds the load which cam be supplied by the only column in service.
Aqua Cubic Plus automatically calculates the volume of water which can be treated, using as a basis the
hardness of the water, the volume of the cylinders and the exchange capacity of the resins used., values
which must be programmed by the operator at the time of the installation of the system.
It is also possible to programme a reserve percentage of the total volume which allows the regeneration of
the resins to be started before they have completely run out.
Aqua Cubic Plus allows for the two columns to be controlled with different dimensional characteristics
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 Plus 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 Plus 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 Plus 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 Plus, 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.

4 – STATES OF VISUALISATION OF THE DISPLAY
The display allows the visualisation of the data and of the operative states. When possible, the key 2/+ allows for the
passing from one column to the other.. In this case, the LEDs A and B will indicate to which column the visualised data
refers.

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-PLUS2/05; 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 Plus 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.
If the system uses a distributor connected with one or two valves, the relative electrical connections must conform to
that indicated in the diagram CE0025 which is shown on the attached page.
If the system uses two distributors connected to one valve each, the relative electrical connections must confrorm to
that indicated in the diagram CE0026 which is 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
-Alarm
-Regeneration in progress
Warning!!
Before carrying out any installation and/or maintenance operation, check that the controller is disconnected from the
electricity supply.
The supply to the controller must take place in accordance with all that is set out in the Low Voltage
directive(73/23/EEC). Aqua Cubic Plus is equipped with a clip for the earth connection.

Aqua Cubic Plus - 9/27
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.
6 – ISTRUCTIONS 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 Plus, 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 Plus 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 Plus has the following operative modalities:

6.2.1 – PPP0 – One single column
6.2.1.a – Operative characteristics
This modality has been designed to resolve emergency cases if Aqua Cubic Plus is used in a duplex system and one
column stops working, it is possible to use the other column singularly and to continue to provide treated water to the
user (see par. 7.5 for details ).
Depending on the programming of the flags, described in the next paragraph, the start-up of the regeneration may be
immediate or deferred to a programmed time. In both cases, the demand for regeneration occurs when the volume of
the treatable water reaches the value 0, or in the presence of a Remote Start signal which has been active for 15
seconds. In the case of deferred regeneration ( at the programmed time ) a control of the treatable volume in relation to
the percentage of the reserve programmed is automatically activated ( see par. 6.4 programming of the reserve ).; in this
case the demand for regeneration is activated when the treatable volume reaches the value of volume calculated on
the basis of the percentage of the reserve programmed.
