I am looking for a way to put a delay on the standard ATO low switch. 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

almost anything is possible.
are you just using the ato low switch? like once it gets triggered you want a delay of x seconds before the outlet turns on. then you want it to run until when? until it is not triggered?

you can also look at the libraries and specifically look at the metalhalide function(s). they implement a delay before turning on to limit the power draw at startup.
something like that can be implemented, only you will have to use the function call for the ato low switch.

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.

I have yet to quite figure this out. Any more input would be appreciated.
