Breakout box

So I installed float switches on my display and overflow box because I run an external overflow. I have them config’d so that the return will turn off if either is tripped. What code do I need to add so that they stay off so its not turning off and on like a yoyo. I need them to shut the return down until I can get home and see whats going on.

BTW shouldn’t my Feed mode A say 005 then on

You'll need to use a virtual output to monitor the float switches, and a When timer to lock the virtual output when triggered:

[Overflow] -- virtual output
Set OFF
If DispOV OPEN Then ON
If OverFL CLOSED Then ON
When On > 000:05 Then ON

[ReturnPump]
Fallback ON
Set ON
If Output Overflow = ON Then OFF
If FeedA 005 Then OFF

[EmailAlm]
Set OFF
If Error Overflow Then ON

If either float switch is triggered for more than 5 seconds, the Overflow output slider will move from AUTO to ON and stay there until you investigate and set it back to AUTO. Adjust this time to your preference. This will also send you an alarm notification.

Out of curiosity, what happens to the overflow water level when the pump turns off for Feed mode? Will that cause either float switch to activate? If so, you'd need to add the If FeedA exception to the Overflow code so it doesn't cause a false alarm.

If you're not familiar with virtual outputs, see my tutorial here:

No so the overflow just drains when the return shuts off so it wont have any effect on that switch. It’s more of a just incase for any reason my overflow stockman standpipe becomes somehow clogged and the return keeps pumping water to it. I had a situation last week where it became clogged with algae I was feeding my tangs. ( made changes so this cant happen again but I just want to be sure.) But it caused a rise in my display water level so I also have a float switch on the display itself. This way if either the overflow water level becomes to high, or the display water level becomes to high, the return will shut down until I fix the issue.

My sump takes on the extra water so it wont effect either of the float switches.
