Could this code work to utilize my DOS as an ATO pump, and How would I add the code?

Hi everyone

I'm trying to figure out if my code will work to keep my ATO going. ATORes is my resivoir, and I dont want it to run if it empties, while ATOTnk is the sensor in my Tank.

If ATOTnk CLOSED Then ON
Defer 000:30 Then ON
If ATOTnk OPEN Then OFF
If ATORes CLOSED Then OFF
When On > 000:45 Then OFF

Would this work? It seems that when setting the pump to 'auto' it works for the 45 seconds, but then the auto goes to off.

Any ideas?

That is a terrible waste of the DOS capabilities to use for ATO. If for some reason you want to use the DOS, you want to go about it a much different way.

First, roughly estimate the volume that your tank evaporates each day and double that. Set a schedule to "dose" that amount evenly over 24 hours.

In the advanced tab add these two lines.

If ATOTnk OPEN Then OFF
If ATORes CLOSED Then OFF

You might be an engineer if...You have no life and can prove it mathematically.

I understand its a terrible waste. We just moved to the States, and downgraded to a 28 gallon, where we have nothing to currently dose. We don't want to spend any more money on the setup, so I thought I could utilize it for now. Is there a reason why you're required to estimate how much will evaporate? Is it a fail-safe?

Yes and it also slows the dosing rate to a slow drip. You could start with a gallon if you don't know for that size tank and then fine tune later by looking at your dosing logs.

OK, thanks for the information. Makes much more sense now.
