ATO tank

[Penipen63]

I have two of the apex switches on my ATO tank. I'm trying to have the low switch when open turn on the solenoid
and the high switch closed turn off the solenoid. So the problem I have is when the low switch goes open the solenoid opens but as soon as it goes back to closed the solenoid goes off. I assume there is a code to tell the solenoid to stay on until the high switch is closed even if the low switch shows closed?

Fallback OFF
Set OFF
If ATT_3 OPEN Then ON
If ATT_4 CLOSED Then OFF
If ALD_1 CLOSED Then OFF

LOL - I provided the answer for this same problem just a few minutes ago. https://forum.neptunesystems.com/sho...nk-osmosi-load

Thanks for the help

so what you said worked but now when my ATT_4 goes open the pump runs until closed. I want it not to run until the ATT_3 is open

What you say here does not seem to correlate with your first post, but you did not previously say what switch does what, so I inferred that based on your ironical programming.

Post the current programming, and also clearly list each of the switch inputs by name and function and position.

When 4 goes open the pump comes on I want the pump to stay off until sw itch 3 goes open

Based on your programming the only thing that will turn it on is ATT_3 going open. Check to make sure the wiring is correct as a break in the wire will look like an open circuit. This is why many people would invert ATT_3 and have it open when closed. That way a broken wire doesn't turn anything on by mistake.

Also make,sure you have the floats connected to the correct switch correctly and don't mistakenly have 4 plugged into the connection meant for 3

So I validated switch 3 is the low switch and switch 4 is the high when I pull 3 from the water it goes open when I put it back it goes closed.
I did the same with switch 4 and it opened and closed. When 3 goes open and 4 is open the pump runs if 3 is closed and 4 goes open the pump runs.
This does not make since like you said there is nothing telling switch 4 to turn on the pump

[RussM]

Which switch is the low one and which is the high one? And tell us the state of both switches when the float is low.

[Penipen63]

Switch 3 is low switch 4 is high there is no floats

If either switch is under water they are closed. If they are not they are open.
Tested both and they are in correct order and working
