6.2.2 – Auto Volume
When Aqua Ionic is programmed in the Auto Volume mode (this condition must be confirmed by
the illumination of the corresponding LED on the panel), the regeneration will be performed when
the set volume exhausts. No reserve calculation or programming functions are available. If the
inhibition signal is present on the proper pin of the DIN 180° socket when the volume exhausts
(Ext. Alarm LED on), Aqua Ionic will not start regeneration. The Alarm output on the DIN 360°
socket is NOT activated. At the same moment when the inhibition signal is deactivated, the Ext.
Alarm LED will be deactivated and the regeneration will start.
During operation, the controller always performs a comparison between the conductivity and the set
point values, even though it cannot start regeneration. If the value read by the probe exceeds the
programmed set point value and remains above that threshold for the whole set time, the alarm will
activate (Alarm LED on the panel and proper output on the DIN 360° socket).
6.2.3 – Auto Set Point + Auto Volume
When Aqua Ionic is programmed in the Auto Set Point + Auto Volume mode (both LEDs on the
panel are on), both checks indicated in par. 6.2.1 and 6.2.2 are carried out. The regeneration is
activated by the check which as first satisfies the conditions required for the cycle to be started.
6.2.4 – Manual
When Aqua Ionic is programmed in the Manual mode (this condition must be confirmed by the
corresponding LED on the panel), the regeneration can be activated only using the Manual Regen
key placed on the panel.
In this operation mode, too, the checks concerning the volume and the conductivity are performed
according to what described in the previous paragraphs. Only the check on conductivity activates
the alarm both on the panel and on the proper output placed in the DIN 360° socket.
6.2.5 – Auto Set point + Manual
When Aqua Ionic is programmed in the Auto Set Point + Manual mode (this condition must be
confirmed by the illumination of both LEDs on the panel), the regeneration can be activated only
using the Manual Regen key placed on the panel. At the same moment when the conductivity
value read by the probe exceeds the programmed set point value and remains above that threshold
for the whole time that has been set, the alarm will be activated (Alarm LED on the panel and
output signal on the DIN 360° socket).
Any volume exhausting will be ignored.
