Would it be best to run the SWCG overnight so that chlorine has time to build up and work without being "eaten" away by the sun? Or is it better to have it producing chlorine throughout the day? I run my VS pump 24/7, but it only runs at 1500 RPM overnight so there isnt enough flow for the SWCG to operate. I just got to thinking, if pools get shocked, or slammed, after the sun goes down so as to minimize the effects of the sun it might make sense.
 
If you are free and clear above min FC, it doesn't matter either way. You are only adding to your reserve stash.

Do factor the daily swing into your calculations. If you only run at night, you'll swing like a liquid chlorine pool. Or if you produce 24/7 it will still swing, but less than a LC pool.

What RPM does the cell need to kick on ?

I read that its 1850 RPM, but I havent tested it yet.
 
I run mine on a split. I run it at night just after sundown, and then I run it again around midday.

I like to think that helps to even out the fluctuations.

how do you do that? Do you control when the SWCG is on by the water flow, or can you turn yours on and off? The only way I have found to turn off the intellichlor is to kill power to it either by disconnecting it from the automation panel, or by killing power to the panel itself.

My Salt Cell panel has a timer on it. That timer turns on both the salt cell and a electric outlet on the controller that my pump is plugged into. When the timer says ON it runs on both the cell and the pump, when it says off, it turns off both. So my panel is also a rudimentary automation panel.

Your Intellecenter should be able to handle turning on your cell and pump, or just your pump, via comm channels. You need to connect the comm ports on the two units. That is what turns on and off the cell, not cutting power. As a safety the cell should be wired on the load side of pump relay, but that is not what controls the operation of the cell, that is more of a fail safe.
 
Which intellicenter (IC) do you have? How many Aux circuits, Feature circuits, Circuit groups?

On the main IC panel screen you should have the “Pool” image/icon. If you press that the pool pump could turn off. You will also see all the lights on the intellichlor go off.

However, if you have/had created and scheduled to run a circuit group that contains the “Pool circuit” (with a specific pump speed i.e. 1400) and have created and named a “feature circuit” (FC) with the same speed as the Pool circuit i.e. 1400. Then when you press Pool to turn it off that also turns off the swg. Without unplugging it or cutting the power.

BUT the pump doesn’t turn off because the FC is still running at 1400 rpm.
