    VO Output Added to ATO Program

    I added a VO to my ATO programming to turn off the ATO during a manual water change. After I added this line of code I noticed that my ATO wasn't on when the sump fill float was closed. I'm certain I have something out of sequence. My code is as follows:

    Fallback OFF
    Set OFF
    If SmpFil CLOSED Then ON
    If SmpHI OPEN Then OFF
    When On > 008:00 Then OFF
    If T_Salt < 33.0 Then OFF
    If Output Water_Cng = ON Then OFF
    Defer 010:00 Then ON

    Please correct or advise what I'm doing wrong. And please let me know what the order is that I need to follow when programming the Apex. Thanks.

    I'm not an expert but mine works pretty well so maybe it will help. This is my VO

    Fallback OFF
    Set OFF
    If ATO CLOSED Then ON
    Defer 060:00 Then ON

    I have a slow pump so I let it run for an hour before it turns off

    This is my ato programming

    Fallback OFF
    Set OFF
    If ATO CLOSED Then ON
    If reserve CLOSED Then OFF
    If Outlet Wtrchng = ON Then OFF
    If Outlet ATOtime = ON Then OFF
    Defer 001:00 Then ON

    Thanks Rye. I’m using my VO as a switch that when the slider is ON it turns off pumps, slimmer and ATO while I do the water change. When I slide the VO to OFF then that equipment comes on. The defer statement delays the ATO from coming on immediately after the VO is switched to OFF.

    I use the same for my skimmer...

    Fallback OFF
    Set ON
    If FeedA 000 Then OFF
    If FeedB 000 Then OFF
    If FeedC 000 Then OFF
    If FeedD 000 Then OFF
    If Outlet Wtrchng = ON Then OFF
    If Outlet Mainpump = OFF Then OFF
    Defer 005:00 Then ON

    The VO is Wtrchng somi reference it in the skimmer programming with a defer statement to keep the skimmer off for 5 min after the water change

    Then you are programming it to function the same way I want my ATO to operate. For some reason it ignored the float position and didn’t come on. And the VO wasn’t in the ON position.

    Did you mean output or outlet?

    If Output Water_Cng = ON Then OFF

    Just a thought?

    You just didn't wait 10 minutes. Your original code is functional.

    You might be an engineer if...You have no life and can prove it mathematically.

    So the code is ok? And do I leave the slider in Auto position until I do a water change and move the slider to the ON position?

    I do this with my "ON demand" virtual outlets so I can't forget about them. I set XXX:XX to me more than long enough for the task but no more time than what I am willing to have it be in said state if I forget about it. When I need to activate it I set it to AUTO, and when done I either set it to OFF or let it expire on its own.


    Set ON
    When On > XXX:XX Then OFF

    That's a good one. I forgot to turn mine off once for a few hours
