Autopilot's new Total Control System

[Poolsean]

The pH will rise naturally with Salt Chlorine Generators so there's very little potential for a LOW pH condition.

hi Sean,
Sorry for having to post my questions here. Your email inbox is full and the Autopilot phone support is busy and email is fastest for me in between meetings.

Wanted to say that the install was easy and the system is well built. The only suggestion is that the VFD should've been built into the main board instead of the plastic shroud which should have a hood for easier viewing in sunlight.

If you don't mind helping with a few questions:

1 - When I have my output set to 10-15%, the display indicates OFF till I go above 40%. Then it'll go OFF when I decrement to about 12%. There's some sort of hysteresis. Is there a reason or something wrong since it won't stay ON when outputing at low settings? The air temperature is about 85-90%.
Even when the display says off, the cell voltage=25v and current=6A.

2- The cell connector has a red plug but which one does it go into or does it not matter.

3- Will it damage the cell if I shock via 15ppm liquid chlorine?

Thanks Sean,
Jackson

Not an official support answer but read it elsewhere in these forums. For #1, the display only indicates ON when the cell is actually generating chlorine. The cell essentially always runs at full power (power levels aside) and the % you set it for is actually the % of time that it is on. Even at 40% it would still go OFF, just less frequently. If you wait long enough with it set at 10% you should see it go on and then cycle back off.

I can't answer #2

For #3 - even less "official" but the SWG superchlorinates in the cell so the ppm within the cell is actually well over 15ppm even under normal operating conditions. I can't imagine that shocking to 15ppm (which isn't an unusually high shock level) would have any negative effect whatsoever.

thanks PCGEEK!
your answers makes a lot of sense if the output duty cycle is what we control.
thanks again.
I'm going to change my pump time to run at night to see if it's more efficient.

Jackson,

If you have the two pin cell, then red plug is there to cap off the third pin that's not being used.

hi PatL34,

I understand that it's for capping off the 3rd unused port but which side? Which of the outer two sides do I cap off?

[PatL34]

It does not matter. With the three pin cell, the center pin was the "neutral" so to speak, and the outer ones are used to reverse polarity. With the two-pin it is taken care of automatically, with the two pins swapping polarity.

Jackson,

Sorry about the full e-mail. You can also e-mail me directly.
PCGeek and PatL have answered correctly. The duty cycle (Purifier %) will indicate ON or OFF, depending on if the cell is energized or not.
The position of the red cap does not matter. You're only using two of the three pins so cap off either outer hole and use the other two.
Finally, it will not affect the SCG to shock the pool if needed. Remember, most people on here recommend using a manual shock to oxidize the combined chlorine from after a pool party or bad weather, rather than using up some of the cell life by doing a BOOST mode. Smart advice to optimize cell life.
