Chlorinator

This page is for the Pentair and Hayward (aka AquaRite, NatureSoft, MineralSprings, SmartPure, etc) Salt Chlorinator

Packets

These packets are a little different than all of the others in this wiki. They all start with 16,2 and end with 16,3. There is no high bit checksum (only a low bit).

Wiring

If you are wiring this yourself, the pinouts are also slightly different than the other pool peripherals.

Aquarite pins:
1=Red=Power
2=Blk = data +
3=Ylw= data -
4=Grn=Ground
