ATO if PH is less than 8.5 and Res is full

All - will this work?
I want to ensure that I have at least 15% water in my reservoir AND PH is less than 8.5 for the ATO to activate. More importantly, I want the ATO to stop if PH hits 8.5
Code: Select all
// Main Top Off
if ( ReefAngel.WaterLevel.GetLevel(2) >= 15 && ReefAngel.Params.PH<850) // Ensure there is 15% of water in the Top Off reservoir and PH is less than 8.5
{
if ( ReefAngel.WaterLevel.GetLevel(1) <= 80 ) ReefAngel.Relay.On(Topoff);
if ( ReefAngel.WaterLevel.GetLevel(1) >= 100 ) ReefAngel.Relay.Off(Topoff);
}

No
But almost there. You got the idea, you just missed one detail.
You need to make sure you turn off the relay should the level go below 15% or ph is greater than 8.5
Code: Select all
// Main Top Off
if ( ReefAngel.WaterLevel.GetLevel(2) >= 15 && ReefAngel.Params.PH<850) // Ensure there is 15% of water in the Top Off reservoir and PH is less than 8.5
{
if ( ReefAngel.WaterLevel.GetLevel(1) <= 80 ) ReefAngel.Relay.On(Topoff);
if ( ReefAngel.WaterLevel.GetLevel(1) >= 100 ) ReefAngel.Relay.Off(Topoff);
}
else
{
ReefAngel.Relay.Off(Topoff);
}

Much appreciated, sir. I assumed that since the relay is set off in the setup area it is by default. But, no harm specifying it!

Well, setup section only happens when your controller boots up, but if you code like this, it would work just as well.
Code: Select all
// Main Top Off
ReefAngel.Relay.Off(Topoff);
if ( ReefAngel.WaterLevel.GetLevel(2) >= 15 && ReefAngel.Params.PH<850) // Ensure there is 15% of water in the Top Off reservoir and PH is less than 8.5
{
if ( ReefAngel.WaterLevel.GetLevel(1) <= 80 ) ReefAngel.Relay.On(Topoff);
if ( ReefAngel.WaterLevel.GetLevel(1) >= 100 ) ReefAngel.Relay.Off(Topoff);
}
