ATO Swich sensitivity adjustment

[AnthonyK]

Is there any way to adjust the sensitivity of the ATO float switch? My sump is a bit wavy at time and it's causing the relay to switch on and off every 10-15 seconds, and it's only on for a couple seconds at a time which isn't even enough for the ATO pump to prime itself. Moving the switches isn't really an option, any ideas?

You can use both switches so that it fills to the High switch and doesn't turn on till the Low switch triggers...

The other option I recommend is to move the ATO pump output away from the float switch.

If neither is an option I think there's some code around that makes sure the switch is active for a time period though..

OK, I have some plumbing I've been wanting to move for awhile now so I'll try that first.

Otherwise is there a way to code the relay (Box1_Port1) to run say every 30 minutes for 2 minutes, but only if the ATO switch is active during that time?

Try this:

Code: Select all

if (ReefAngel.LowATO.IsActive())
  ReefAngel.DosingPumpRepeat(Box1_Port1,30,120);
else
  ReefAngel.Relay.Off(Box1_Port1);

Finally got a chance to try this tonight. The RA doesn't like the second line down, it gives me an error message that reads:

"no matching function for call to 'ReefAngelClass::DosingPumpRepeat(int,int,int)'"

Sorry, I missed one parameter:

Code: Select all

if (ReefAngel.LowATO.IsActive())
  ReefAngel.DosingPumpRepeat(Box1_Port1,30,120,0);
else
  ReefAngel.Relay.Off(Box1_Port1);

Wow you're fast! I'll try it and let you know how it works. Thanks!

[AnthonyK]

It took it!

I'm trying to learn all this code stuff so I don't have to bother you all whenever I need anything. Can you tell me what that code means?

After I looked at that link, I realized the code was wrong...
Needs to be like this:

Code: Select all

if (ReefAngel.LowATO.IsActive())
  ReefAngel.DosingPumpRepeat(Box1_Port1,0,30,120);
else
  ReefAngel.Relay.Off(Box1_Port1);

Offset of 0 minutes, every 30 min for 120 seconds
