1 – BASIC CHARACTERISTICS
Aqua Timer Plus is dedicated to the control of a SIATA multi-port valve for the realisation of water softening systems, working on the principle of ionic exchange resins.
Aqua Timer Plus can control a hydraulic distributor which, with one or two SIATA valves, forms an electrical/hydraulic command unit for single or duplex systems.
When Aqua Timer Plus is programmed in a duplex mode, it is possible to activate a particular regeneration cycle, which has a stand-by position at the start of the regeneration.
Aqua Timer Plusautomatically calculates the volume of treatable water based on the following parameters:
the hardness of the water
the volume of the tank
the capacity of the exchange of the resins used
The regeneration cycle is entirely programmable and may be run in three different ways:
by time (the programmed time running out sets off the regeneration)
by volume (the programmed volume running out sets off the regeneration)
mixed (this is a combination of the first two)
manually
by an external signal (remote starter)
It is also possible, by pressing the key Reset to cancel a regeneration in progress, or to jump one or more phases by pressing the key Regener during the stop phase.
Aqua Timer Plus makes it possible to use an outlet which is activated during the second phase of the regeneration cycle (phase 2C normally used for having the regenerants moved along the resin), which may be used to control the supply of an electrolytic cell for chlorine or any other electrical controller.
Aqua Timer Plus is equipped with a counter of the regenerations which may be carried out with the salt introduced into the system; the controller will emit an alarm when it is the right time to restore the salt level.
Aqua Timer Plus may be connected to a computer via RS232 using the correct cable serial cod. 881-1, so as to be able to acquire and then analyse the progress of the work parameters.
Aqua Timer 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 Timer 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 Timer 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.

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 infrormation: name of producer and PN producer AT-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 controller 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 removing 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 Timer 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 CE0027 shown on the attached appendix A.
If the system uses a single hydraulic distributorconnected with one or two valves, the relative electrical connections must conform to that indicated in the diagram CE0028 which is shown on the attached appendix B.
If the system uses a duplex hydraulic distributorconnected to one valve each, the relative electrical connections must conform to that indicated in the diagram CE0021 which is shown on the attached appendix C.
Also follow the instructions shown in par. 6.11 on the connections.
The controller is equipped with free contact outlets with the following signals.
-Dosing pump
-End of cycle impulse
-Impulse during phase 2
-Alarm
-Regeneration in progress
Warning!!
Before carrying out any installation and/or maintenance operation, check that the controlleris disconnected from the power 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 Timer Plus is equipped with a clip for the earth connection.
5.4 – Protection devices
The controller 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.
If the version supplied at 24 Vac is used, the fuse is 1A retardant.
An Autoreset circuit intervenes automatically if Aqua Timer Plus stops functioning after particularly strong disturbances.
6 – INSTRUCTIONS FOR USE
6.1 – Turning on
The controller is turned on via the main switch ON (I) - OFF (0) situated on the front panel. This switch acts on both supply conductors.
The supply voltage must be 230 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 Timer Plus, it must be checked that the distributor cams are positioned at the limit cycle position. If operations are to be carried out on the controller before its installation, that is without the distributor connected, the limit switch entry must be closed with a connection bridge. If this simple rule is not respected, Aqua Timer Plus will accept all the new programming, but will not be able to carry out the normal operations needed during the service.
The programming will be carried out via the keypad on the front of the controller.
Aqua Timer Plus has the following operative modalities:
Tab. 4 – Table of the operative modalities
Code / Description / Cam rotation timesL L L 1 / One single column / 4 stop with 50 second rotation time
L L L 2 / One duplex column / 4 stop with 25 second rotation time
