Operate on Skimmer when pH is out of specified range

[Jeffreyp226]

I have a skimmer hooked up to a co2 scrubber. I would like to create an output which would turn on when my ph is out of a certain range. This output would control the skimmer via the “depends on” by turning it on when ph reaches a minimum point (say 8.2) and off when it reaches an upper level (say 8.4). I’m having trouble figuring out the generic settings for ph. If I want the output to turn on when ph reaches 8.2 and off at 8.4 would I set my ph to these levels and select ph low? I’ve attached a screenshot of this configuration. I’m having trouble figuring out the ph low vs ph high option.

Thank you

It has to get below pH 8.2 but will not turn off till it get to 8.4. Then it will have to get below pH 8.2 to turn back on. Is that what you want?

Yes once it gets below 8.2 it will turn on until ph hits 8.4 when it will turn off. When it drops to 8.2 again the skimmer turns back on.

That should do it. Set the depends on on the skimmer to this output and set it to off if off. You can also setup any depends on on the skimmer currently on this output and it will still work if it is to turn off the skimmer.
