"Slave"
mode only controls chlorinati on. The fi lter pump, accessories, lighti ng and other functi ons remain valid.
A press of the
key has priority over
"Slave"
mode.
If a Dual Link module is installed, the ORP functi on is ignored by the
"Slave"
mode. pH regulati on remains valid.
"LOW"/"COVER"/"BOOST"
modes have priority over
"Slave"
mode.
Slave mode operates as follows: "contact closed = chlorinati on ON/contact open = chlorinati on
OFF".
5.2.13 Confi guring the durati on of polarity reversal
The polarity reversal principle eliminates scale that has deposited on the electrodes by reversing the electrical power at
a specifi ed ti me. By default, the cycle is reversed
every 5 hours.
The hardness of the water varies depending on the geographical region concerned (water hardness = TH).
In order to protect the electrodes from scale build-up (which reduces the effi cacy of the electrolysis reacti on), the
polarity reversal ti me can be adjusted.
•
Before setti ng the polarity reversal ti me, analyse the hardness (TH) of the pool water, see
“4.1 I Balancing
the water”
.

• Press
and browse the menu using the
butt ons.
Press
to confi rm.
•
Select the polarity reversal ti me (can be set every 2 to 8 hours)
using the
butt ons.
Press
to confi rm.
• Press
to exit.
At the ti me of reversal, chlorinati on is stopped for a few minutes. No message is displayed on the screen.
Normal operati on resumes aft er reversal is complete.
