6.5 – Remote Start
Aqua Cubic Multiplex
makes a «remote start» entry available which allows for the regeneration to be started up by an
external automatism
or manually via a button positioned at some distance from the controller. Whichever device is
used, this must be of the
normally open
type, and to start up the regeneration, must be closed for at least 15 seconds.
The remote start is available only when only one distributor is active, therefore in the modality
PPP0,
one single
column and
PPP4,
one duplex column.
In the first case, the start of the regeneration may be immediate or deferred to the programmed time, depending on the
programming of the flags
0HP
and
2HP
as described in par. 6.2.1.a.
In the second case, the remote start is automatically enabled for immediate start. It is not programmable in any way.
6.6 – Programming of the litre counter divider (prescaler)
The programming of the litre counter divider (
prescaler
) defines the ratio between the number of
impulses
read by
Aqua Cubic Multiplex
and
the unit of load
in transit in the counter used ( litres or m
³
) .
Aqua Cubic Multiplex
has two work modes:
free prescaler
if the flag
0CP
is equal to
0
; in this case the prescaler may be programmed within the range of
values 1
÷
899 (n° of impulses given by the litre counter before the volume climbs by one unit);
pre-programmed prescaler
if the flag
0CP
is equal to
1,
in this case the prescalers which can be used are those
indicated in the first column of table 18;

The volume calculated by
Aqua Cubic Multiplex
can go from 0 to 999,999 litres. This value is optimised in order to be
able to be visualised by the display of the controller which can show only four digits.
A decimal point will appear on the display to separate the cubic metres from the litres, that is the thousands of litres
from the hundreds.
The value of the volume will be visualised from the left to the right, so that a volume value of 15,500 litres will be
visualised as
15.50
, a value of 350,000 litres will appear as
350.0
. During the service, the normal consumption of water
will cause the volume visualised to decrease; when the most significant digit becomes zero,
Aqua Cubic Multiplex
will optimise the visualisation moving the reference point towards the left, which allows new, less significant digits to
be seen. Thus, the moment the volume passes from 10,000 to 9,999 litres, the visualisation will pass from
10.00
to
9.999,
if the volume passes from 100,000 to 99,900 litres, the visualisation passes from
100.0
to
99.90
.
