Controll ORP

[anderzon_]

Is it possible to control the ozone generator with a ORP expansion to a specific level. Type to shut off if it gets too high and turns on when it gets too low?

Yes. Very easy. I got a thread somewhere if you do a search you will find it. Sorry but im on tapatalk only atm

will this code work even if it says further up in the code that port 3 is always on?

Code: Select all

Yes, it works.
setup() section only happens once at start up and never again.
But your logic is wrong.
You used >= on both lines.

Code: Select all

    if (ReefAngel.Params.ORP>=400)ReefAngel.Relay.Off(Port3);
    if (ReefAngel.Params.ORP>=300)ReefAngel.Relay.On(Port3);

[anderzon_]

Thanks

I see, would this work?

Code: Select all

if (ReefAngel.Params.ORP >= 400 ) ReefAngel.Relay.Off(Port3);
if (ReefAngel.Params.ORP <= 300 ) ReefAngel.Relay.On(Port3);

[rimai]

That works

[anderzon_]

Thank u

If I delete this line from the setup section what would happen then?

Code: Select all

ReefAngel.Relay.On( Port3 );

[rimai]

Nothing you would see.
You would probably save a few bytes of code, but nothing noticeable would happen.

The code you posted here has an undefined region between 300 and 400. The code line in the setup will turn on your ozone unit at power up (power cycle)... If the line is removed I assume it will be off until the Orp level goes down to 300.
