.
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
A
will 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
