How to control DOS to turn off for extremes in pH

[recess62]

I am doing alk and white vinegar with the DOS. I would like to have the apex switch off the Doser if ph > 8.3 if the alk Doser fails and turn off the Doser if the ph falls below 7 .8. So is is possible to program the outlet to only be on if pH is between 7.8 and 8.2?

Yes. Doing this is covered in the DOS Get Started Guide. https://www.neptunesystems.com/getstarted/

Follow the example given. Add additional If pH statements as desired.

If pH > 8.3 Then off
For some reason I had to rename my pH for it to work for dosing Kalk.
I don't know if I would personally dose Alk according to ph because lots of factors effect pH, not just alkalinity levels but it's a good safe guard!
