I'm trying to wrap my head around something that just started the other day. This is the first time I've drained my RODI tank so I could mix up a new batch of saltwater after building my mixing station.
When I drained the tank, the ATO pump was sucking air and tripped my vATOTime outlet because it ran more than 2 minutes. I filled the RODI tank and turned off my vATOTime outlet and then put it back to Auto.
But for some reason, it keeps going back to ON. When I turn it off and back to Auto, the status changes from "Auto" to "Off". About 2m 30s later, it turns ON again even though the ATO outlet is off and the sump switch is OPEN. None of the other conditions are satisfied. It's just turning itself on for no reason.
Here is the code:
ATO
Fallback OFF
Set OFF
If SumMid CLOSED Then ON
If Outlet vHi = ON Then OFF
If Outlet vLo = ON Then OFF
If Outlet vATOTime = ON Then OFF
Defer 000:30 Then ON
Min Time 015:00 Then OFF
If Outlet vTankLeak = ON Then OFF
If Outlet NSWDos = ON Then OFF
vATOTime
If Outlet ATO = ON Then ON
Defer 002:00 Then ON
If Outlet vReset = ON Then OFF
Here is a screen shot of all the outlets the instant it turns itself ON. The ATO outlet showed as OFF the entire time I was watching.
There isn't anything ON that should turn it on and it's been working just fine for 3 weeks. I'm lost.
