"Slave"
mode only controls chlorination. The filter pump, accessories, lighting and other functions remain valid.
A press of the
key has priority over
"Slave"
mode.
If a Dual Link module is installed, the ORP function is ignored by the
"Slave"
mode. pH regulation remains valid.
"LOW"/"COVER"/"BOOST"
modes have priority over
"Slave"
mode.
Slave mode operates as follows: "contact closed = chlorination ON/contact open = chlorination
OFF".
5.2.13 Configuring the duration of polarity reversal
The polarity reversal principle eliminates scale that has deposited on the electrodes by reversing the electrical power at
a specified time. 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 efficacy of the electrolysis reaction), the
polarity reversal time can be adjusted.
•
Before setting the polarity reversal time, analyse the hardness (TH) of the pool water, see
“4.2 I Balancing
the water”
.
Water hardness (TH)
Recommended polarity reversal time (hours)
< 15°f (150 mg/L or ppm)
6 - 8
15 - 30 °f (150 - 300 mg/L or ppm)
5
30 - 40 °f (300 - 400 mg/L or ppm)

• Press
and
browse the menu using the
buttons.
Press
to confirm.
•
Select the polarity reversal time (can be set every 2 to 8 hours)
using the
buttons.
Press
to confirm.
• Press
to exit.
At the time of reversal, chlorination is stopped for a few minutes. No message is displayed on the screen.
Normal operation resumes after reversal is complete.
