COR-20 Programming to prevent overflow

[djbetterly]

I just picked up a new tank and a new COR-20. The new tank has a single durso overflow drain, no emergency overflow. I’d like to put a float switch in that if triggered it would set the COR-20 to its IQ Min setting and send me a notification. The notification I know how to do but with limited info on the COR-20 programming I’m unsure how to set that.

Thank you!

Overflow
Set OFF
If Switchname OPEN Then ON
Defer 000:10 Then ON
Defer 000:10 Then OFF

OverflowEm
Set OFF
If Switchname OPEN Then ON
Defer 002:00 Then ON
Defer 000:10 Then OFF
When On > 000:02 Then ON

Cor advanced tab
If Output Overflow = ON Then 1
If Output OverflowEm = ON Then OFF

Email
If Output Overflow = ON Then ON
If Output OverflowEm = ON Then ON

So does that set the output to 1% or does 1 just mean the minimum?

That sets it to minimum while the float is open and if after 2 minutes the float hasn't restored itself and remains open, it will latch OFF the return until you manually intervene.

Awesome! When I go to program it this week I might have a couple more questions. Looks pretty straight forward though.
