How does this control work?

That's meant for equipment that raise pH.
Turn on when it gets lower than X pH and turns off when it gets higher than Y pH.

Thank you Roberto is this based on the main pH reading or the PH expansion unit?

main pH, but we can easily replicate that to work on the expansion too.

Thank you I cannot program so I rely on the wizard. Is it easy to change? If not I am just going to keep the main tank on the expansion unit. What is the tolerances for the switching?

You can code it as tight as you want, like turn on at 7.91 and off at 7.92, but that is going to give you a lot of turn on/off.
If you want to use the ph expansion module, you can add this to your code:

Hi I am still struggling to get the RA to switch on and off with the PH control
Please could you look at the code below and tell me what I am doing wrong

Which equipment are you trying to control based on pH?
PHControl is for equipments that raise pH and CO2Control is for equipments that lower pH.

I am trying to control my calcium Reactor

solinoid valve

You must use the CO2Control and not PHControl.
Your equipment lowers pH.

I am not measuring CO2

I am trying to switch the solenoid of when the PH is 6.2 and on if the PH gets above 6.5.

I am trying to switch the solenoid of when the PH is 6.2 and on if the PH gets above 6.5.

Exactly... You are controlling something that lowers pH.

So how should I do this

Use this:

You are a absolute star it is working. Where are you in the world?
I am in South Africa

Cool
Glad you got it working now. I'm in the USA

Should you ever come to South Africa you are welcome to look me up.
Have a great day
