Basic Characteristics - SIATA Aqua Timer Plus Use And Maintenance Manual

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 Plus automatically 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
