Another ATO question - single ato + backup

Post by neuro »

Hi all, I apologize for another ATO question, but I swear this one should be easy:

- I want to set the ATO to single, using ATO Low to trigger the pump to feed the water to top off my sump.
- I want to set the ATO high as a backup switch, so if the first ATO low fails, the second will stop any overflow from happening.

Can anyone see an issue with this?

this is what im using with two float switches, a 12v solenoid/valve and a wall wart.

Code: Select all

//global

#define ATO 8

//inside void loop

//ATO Low Activation with High Safety (Port 8)
    if (ReefAngel.HighATO.IsActive()) ReefAngel.SingleATOLow(ATO);
      else ReefAngel.Relay.Off(ATO);
