Anyone have any tips or suggestions on whether or not this looks right? This is based off of the PH in the reactor.

Here’s mine
Fallback OFF
If CRX_pH > 6.70 Then ON
If CRX_pH < 6.60 Then OFF
Defer 001:00 Then OFF
Defer 001:00 Then ON
If Output CRx_Pump_7 = OFF Then OFF

Thanks! What is the Defer portion about?

The defers insure that a quick spike either direction will not shut off or on the regulator. I want it to be in the max/min zone for a minute before turning on or off.

My regulator never shuts off tho. I hold steady at 6.65 (right inn the middle of my set points) pretty much all the time. Here is a screen shot. The big peak at the beginning is where I had shut it off for a few minutes for maintenance.

Do you have a screen shot of your pH graph?
