Delay ATO after feed cycle

I was wondering if someone could help me with adjusting my ATO outlet on my apex to not come on within 5 min of a feed cycle ending.

Reason being, when the pump comes back on, the return pump has to fill the coast to coast chamber of the overflow before the siphon starts and this will take more water out of the return chamber in the sump until the siphon starts and refills the return chamber. If the ATO timer is set to check the switch at that time, the ATO will turn on until the siphon puts all the water back in the return chamber.

Here is my ATO programming:

Program Type: Advanced
Display Icon: Spigot
Program:
Fallback OFF
Set OFF
If Sw1 CLOSED Then ON
If Sw2 OPEN Then OFF
Min Time 030:00 Then OFF
If FeedC 000 Then OFF

Feed C is 60 min for tank maintenance.
The main feed cycles are FeedA and FeedD. These are 5 min.
Sw1 is the low water level
Sw2 is the high water level

How can I get ATO to delay 5 min if I just come off FeedA or FeedD?

Just add a defer statement at the last line of your outlet program and it will keep it in the OFF state until the time is up :

Defer 005.00 Then ON

I only want it to Defer for 005:00 if the ATO timer is up when the Feed is on. I dont want to defer the ATO all the time...

I think this is what I need: If FeedA 005 then OFF

So it would be:

Fallback OFF
Set OFF
If Sw1 CLOSED Then ON
If Sw2 OPEN Then OFF
Min Time 030:00 Then OFF
If FeedC 000 Then OFF
If FeedA 005 then OFF

Thanks Apex New User Guide!

Remember that the statement are evaluated from top to bottom , the last one will determine the state of the outlet .

You can create a virtual outlet and add this outlet to your ato outlet as this :

Virtual_Feed

Set OFF
If FeedA 000 Then ON
If FeedD 000 Then ON
Defer 005:00 Then OFF

Ato_Outlet

Fallback OFF
Set OFF
If Sw1 CLOSED Then ON
If Sw2 OPEN Then OFF
Min Time 030:00 Then OFF
If FeedC 000 Then OFF
If Outlet Virtual_Feed = ON Then OFF

Does the virtual outlet just allow me to check for Feed A or FeedD being on? And it will last for Feed A/D duration plus the 5 min in the Defer statement?

What is the difference between that and Feed A 005 or Feed D 005 in two statements? They are IF statements where only one could be true at one time

The VO will be on at any time you will initiate a FeedA or a FeedD and go back to OFF 5 minutes after the time on FeedA or FeedD Is complete as you had set the time for the feed in the misc page on your apex dashboard . i prefer this kind of programming as it will permit you more possibilities of adjustement to the cycle . AS the VO outlet is the last one in your ATO outlet it will keep this outlet off at anytime a feed statement is initiated . Using the feed button will trigger the VO ON and also the ATO off for the feed duration plus 5 mins .

Will the Defer 005:00 keep pushing the Min Time 030:00 back? Right now it checks Sw1 every 30 min for state and will add water if SW1=Closed. If I add Defer will it just make the next check 25 min or do a 30 from the additional 5 added from the defer? SW1 wont be Closed after Feed A + 5 min all the time, so will it eventually get back to every 30 min from Min Time 030:00?

Sorry if this is confusing. Guess I should just run it and see what happens.

Here the Defer statement only apply to the Virtual_Feed outlet , it will not interfere with the normal operation of the ATO outlet unless you have triggered a feed mode .
