My DC pump causes a little turbulence in that chamber. If ATO is low for longer than x then turn on the standard ATO port. Thanks

I'm using the standard low and high. I just want the low active for x (maybe 5 seconds) before triggering the ato pump port and run until the high switch is active.

So just like normal but with some deadband on the low switch.

It's been a while since I started this, low priority. I made a stab and came up with this, but I can't seem to make it work. Any help would be appreciated.

Code: Select all: unsigned long LastATO; if (ReefAngel.LowATO.IsActive()) LastATO=millis(); if (ReefAngel.HighATO.IsActive() || ReefAngel.isATOTimeOut()) LastATO=0; if (millis() - LastATO < 60000) ReefAngel.Relay.Off( Port8 ); else ReefAngel.StandardATO( Port8 );

It looks to me like LastATO is constantly updating with current millis value while LowATO.IsActive, meaning millis - LastATO is always 0. How do I correct?

Below is the code I came up with for this. I have been scratching my head as to why but the issue with it is that it only works the fist time. Every subsequent time upon the low level switch goes true, my ATO timeout will immediately come on. Any one have any insight on this?

Code: Select all: // ******************* Debounced ATO code. Only run ATO if LowATO is true for more than 10 sec. ******************* if (ReefAngel.HighATO.IsActive() || ReefAngel.isATOTimeOut()) { topoff = false; SnapShot = 0; ReefAngel.Relay.Off( Port8 ); //ATO Pump Off } else if (!ReefAngel.HighATO.IsActive() && !ReefAngel.LowATO.IsActive()) topoff = false; else if (ReefAngel.LowATO.IsActive()) topoff = true; if ((topoff == true) && (last_topoff == false)) SnapShot = millis(); // check if this is the first time that lasttopoff and topoff are different and store snapshot of time last_topoff = topoff; // update topoff if (topoff && (millis() - SnapShot >= 10000)) { //run ATO normally if ATOLOW is true for more than 10 seconds ReefAngel.StandardATO( Port8 ); //ATO Normal ON
