3.6.5 «OFA Time» Menu
The appliance is fi tt ed with a safety mechanism to avoid all risks of correcti on product overdoses if a problem occurs with
the sensor for example. This safety mechanism, which is called «OFA» (=Over Feed Alarm), pauses the appliance if it has
not reached the set point within a given ti me limit. A high value is strongly recommended to avoid any unplanned and/or
unjusti fi ed triggering (a setti ng in excess of 4 hours is suitable for large pools and/or highly used pools).
The over feed safety operates in two main steps:
•
fl ashes aft er 70% of the programmed ti me without having reached the set point
•
displays when the ti me is up. The appliance then switches to safety mode.
If fi ltering stops and restarts (=daily cycles) while the appliance is in «Stop OFA» status, the appliance will acti vate an «OFA
Test» mode for 1 hour to make sure the measurement from the sensor is correct.
On completi on of this «OFA Test» mode:
-
if the set point has been reached = the appliance remains in normal mode
-
if the set point has not been reached: the appliance switches to «OFA Alarm» mode with an injecti on of corrector
product.
-
if the set point has sti ll not been reached aft er the «OFA Alarm» mode is complete (=25% of total OFA set ti me), the
appliance switches to «OFA Stop» safety mode and will remain in this state unti l a human interventi on.
To acquit this safety measure and restart the appliance, press the
. key. First make sure the sensor is in good conditi on
and calibrated.
Special over feed safety functi on:
In order to prevent false alarms just aft er the appliance is installed, the over feed safety can be deacti vated for 24 or 48
hours:
• Press
,
and
at the same ti me to deacti vate the safety system for 24 hours
• Press
,
and
at the same ti me to deacti vate the safety system for 48 hours
3.6.6 «Calibrati on» Menu
This functi on can be removed (we advise strongly against this, except in the case of pools with a maintenance contract).
3.6.7 «Filtering» Menu
This appliance is fi tt ed with a double electric power supply making it possible to keep the appliance switched on to carry
out Redox sensor calibrati on when fi ltering is not operati onal. This functi on can however, be deacti vated in the case of a
diff erent electrical connecti on (only carried out by a professional).
The appliance will no longer take fi ltering status into considerati on and may inject corrector product when
there is no fl ow in the piping. This deacti vati on is only valid if the mains power cable is coupled to the fi ltering.
3.6.8 Resetti ng the appliance

•
Turn the appliance back on while pressing
and
at the same ti me:
