Nilsen reactor

[johniii]

This weekend I will be getting a mrc Nilsen reactor.

I need to set my ato so that if the reactor has run in the last thirty minutes it won't turn on the pump. How would one go about coding this?

How do you turn your reactor on/off?

Going to use port 1 on a schedule

Can you post an example?

[johniii]

Haven't wrote the code yet. But will be port 1 on every hour for 5 mins.

I guess I need a if else statement for the ato.

Just don't need the ato to come on if the reactor has just stirred the kalk.

[rimai]

That would mean you only want the ATO to work the last 25min of every hour, right?

[johniii]

Yes that should work

if you are going to run port 1 for 5 minutes every hour on a schedule, then you could use the dosingpumprepeat functions.

Try this and see if it works:

Code: Select all

  if (now()%3600<2100)
  {
    ReefAngel.Relay.Off(Port2);
    ReefAngel.LowATO.Timer=millis();
  }
  else
  {
    ReefAngel.SingleATO(true,Port2,60,0);
  }

  if (now()%3600<2100)
  {
    ReefAngel.Relay.Off(Port2);
    ReefAngel.LowATO.Timer=millis();
  }
  else
  {
    ReefAngel.SingleATO(true,Port2,60,0);
  }

Will try it and see.

But for the sake of me learning and not having to bug you guys, what do the numbers on the first line mean

It's seconds.
3600 = 1 hour
2100 = 35 minutes
% is a mathematical operation called modulo:
