"Slave" mode only controls chlorinaon. The lter pump, accessories, lighng and other funcons remain valid.
A press of the key has priority over "Slave" mode.
If a Dual Link module is installed, the ORP funcon is ignored by the "Slave" mode. pH regulaon remains valid.
"LOW"/"COVER"/"BOOST" modes have priority over "Slave" mode.
Slave mode operates as follows: "contact closed = chlorinaon ON/contact open = chlorinaon
OFF".
5.2.13 Conguring the duraon of polarity reversal
The polarity reversal principle eliminates scale that has deposited on the electrodes by reversing the electrical power at
a specied 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 ecacy of the electrolysis reacon), the
polarity reversal me can be adjusted.
• Before seng the polarity reversal me, analyse the hardness (TH) of the pool water, see “4.2 I Balancing
the water”.
Water hardness (TH) Recommended polarity reversal me (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) 3 - 4
> 40°f (400 mg/L or ppm) 2 - 3
• Press and browse the menu using the buons. Press to conrm.
• Select the polarity reversal me (can be set every 2 to 8 hours) using the buons. Press
to conrm.
• Press to exit.
At the me of reversal, chlorinaon is stopped for a few minutes. No message is displayed on the screen.
Normal operaon resumes aer reversal is complete.
