Which regulator? And which plug on the PC4 do you have it plugged in? How do you have it programmed?

I have a Milwaukee regulator and have it plug into number 1 plug . Have it program on the pc4 function is set to controller Device pH set .6 .70 on when below 0.01 and on when above 0.01 have the standby on and default set to off

Right now it's running at 6.75 and has not cut off

I I misspoke is still on right now because it needs to be lower the pH but when it gets below 6.7 it doesn't cut off

What is confusing is it shows onwhen above and On went below but it doesn't show a off when below

It seems to me that the .01 is a real tight tolerance which may cause issues. What does the bubble rate look like? When I had mine plugged into the RKE it seemed like it needed a higher power draw, could've been plugged into the wrong port though.

I'll try widening the tolerance and see what happens
