Calcium reactor problem

I just installed a calcium reactor and I control the solenoid valve through Ferduino, the problem is that it behaves erratically and never reaches the desired pH, it cuts before reaching the value (normally around 6.98), every now and then. when it is activated for a short time and then is inactive for a long time.

The valve works correctly because if I connect it directly to the electrical network it works constantly, or if in the "Outlets settings" It is set to "Always on", it also works continuously. While if it is in "Automatic mode" it is when it does not behave as expected.

The parameters that I have defined are:

PHR = The current measurement
SETPHR = 6.4
OFFPHR = 0.2
ALARMPHR = 0.2


I use the PCF8575 module AND the associated relay is connected as "NO"


EDIT: I answer to myself, I was not taking into account the volume of the pH of the tank and when the reactor was in operation it made it drop more than the configured limit and cut the solenoid x_x

Hi!

Parameters can't be configured via code it should be via touch screen or web interface.

Also there is a security function that will turn off the calcium reactor if tank pH is lower than desired.

    if (PHA < (setPHA - offPHA)) // Se PH do aquário menor que o desejado menos a variacao permitida.
    {
      bitWrite(status_parametros, 5, 0);
      PCF8575.digitalWrite(reatorPin, LOW);   // Desliga co2 do reator de cálcio
    }


Best regards.

So I think the security function is working. =))

Can you mark this topic as solved?
