Need quick and reliable code for ATO

[Kahuna]

I just switched over from another controller to an Apex, and don't have my float switches set up yet - need a breakout I/O module. Meanwhile, I need some RELIABLE code to run my ATO pump for 45 seconds daily.

Thanks for assistance in advance.

Anyone? Bueller? Anyone?

You did not really give much to go on, but if you only need to run a pump for 45 seconds each day, this should do the trick.

[ATO]
Set OFF
If Time 1:00 to 1:01 Then ON
If pH > 8.4 Then OFF
Defer 1:15 Then ON

I arbitrarily chose late at night assuming you might be adding kalk or a high pH alk supplement. Same for the pH check. The Time statement actually creates a two minute duration, and the Defer 'deducts' a minute and 15 seconds.

Thanks, guys. I lose about a gallon a day, and want to top off with RO dosed with alk and calcium to tank parameters while out of town for a few days. I'm using a Minijet 300 pump and if it runs for about 45 secs it gives me about a gallon. I'll toss this code into a relay-controlled outlet so it WILL shut off electrically.

Thanks very much for your assistance.

I hope you are not using an Alk supplement that is high pH, a gallon all at once would be a pretty big bump.

No, my RO comes out at approx 1 dKH, so I supplement each gallon with 4 ml of Randy's Recipe Alk to bring the alk of the top-off water to around 8.5 dKH. That way it's the same parameter as the tank. If I set the calcium of the RO, which comes out at zero, I bring it to about 430ppm. That way, the RO going into the tank gives it a light boost of calcium and maintains the alk level.

If this is wrong, I'd really like to know, coz I've only been doing this about 6 mos.
