There are something not correct in your code.
You are using channel 2 for the pump control:

Code: Select all

  PWMValue=OperatingPWM;
  if (ReefAngel.WaterLevel.GetLevel(2)<Level-4)
  {
    override=true;
    lastmillis=millis();
    PWMValue+=2;
  }
  if (ReefAngel.WaterLevel.GetLevel(2)>Level+2)
  {
    override=true;
    lastmillis=millis();
    PWMValue-=4;
  }


And then the same channel for overfow control:

Code: Select all

  if (ReefAngel.WaterLevel.GetLevel(2)>89) //Overflow
    ReefAngel.Relay.Off(Port1);
  else
    ReefAngel.Relay.On(Port1);


So effectively, your first code does nothing.
The second code supersedes and then you will only get port1 off when level is greater than 89.

OK, I see now. That code shuts the return off if my overflow is greater than 89 so it won't overflow if my drain is plugged. What can I do if I want to keep that and still toggle port one when my sump level is too high for too long? Do I need to use a float switch in the sump instead of using the standpipe or is there something that can be changed in the code to allow me to use both codes simultaneously?

If the sump level is at 82 and your code is set to 89, it will never turn off.
Change 89 to something smaller.

I guess I'm still confused. The sump level was only at 82 because I submerged the standpipe to test the code. It's supposed to turn off the return when the level is 50 or higher for at least 16 minutes. Normal levels for the sump are around 30. The 89 is the max level of my overflow so it shuts off the return to keep it from overflowing the tank if there is blockage. Channel 2 is for my overflow and channel 4 is my sump.

Your code doesn't even use channel 4.

Sorry, I was looking at the code you posted before.

Thanks, Roberto. It works but just need to change 15 minutes to 15 seconds. How do you code this?

16*SECS_PER_MIN is equal to 16 * 60 seconds, which means 16 minutes.
If you want 16 seconds, just remove the SECS_PER_MIN, which will be just 16 seconds.
