ATO coding

is there a coding for the ATO system were it goes on at set times of the day and uses the two floats as a shut off point?

my current sump is a DIY and what i have is a glass baffle box inserted and for some reason the 20lbs box wants to float if the water gets to low, so i'd like to change how the basic ATO function is to use both as a stop point for a solenoided RO holding tank ATO reservoir. which will use the same ATO plug to power the solenoid

Not sure I understand what you want.
Can you explain a little better?

i want to have the ATO come on at a certain time of day, say 4PM and have the Float switch turn it off.

want to use both switches but when one hits the high limit it'll shut off and the other one as a back up just incase one seizes up

Let's say it starts at 4pm and it turns off when it hits the float. Does it mean it would only turn on again next day at 4pm?

You can use something like this:
Code: Select all
if (ReefAngel.LowATO.IsActive())
{
  if (elapsedSecsToday(now())==57600) ReefAngel.Relay.On(Port1);
}
else
{
  ReefAngel.Relay.Off(Port1);
}
if (!ReefAngel.HighATO.IsActive()) ReefAngel.Relay.Off(Port1);
