    Using feed for water change

    I know I can do this however I recognise that cancelling the feed mode will switch all outputs back on immediately. I need a delay for my wavs and my skimmer if I cancel early and understand that I need to use a virtual outlet to allow me to do that but when I've tried I can't get the desired control. Selecting FeedB switches on virtual outlet Water_Change. I need the return to come on straight away once FeedB is cancelled but the three other devices to delay start for a further 5 minutes until levels are restored. I'm thinking these need to go into the individual devices programmes rather than the VO (as that would defer the return pump turning back on immediately as it applies to the entire output). So I need to add the code for the delay into the statement for individual devices for example this is my skimmer code

    [Skimmer]

    Fallback ON
    Set ON
    If FeedA 010 Then OFF
    If Output Water_Change = ON Then OFF
    If Output COR_RETURN Percent < 99 Then OFF
    If Error COR_RETURN Then OFF
    Defer 005:00 Then ON

    and this the code for my VO for water changes, using FeedB as the control.

    [Water_Change]

    Set OFFFallback OFF
    If FeedB 000 Then ON


    I'm sure I'm missing something obvious, can anyone help please.

    You only need the VO for the WAVs (assuming they only need 5 minute delay for this feed mode). The skimmer doesnt need the VO or the feed statement at all since it's already related to your return pump and delayed 5 minutes.

    Cheers Good point so should the code for the VO be

    Set OFF
    Fallback OFF

    If FeedB 005 Then ON

    Or if not then where how and where do I create the five minute delay for when I cancel the feed mode before it complete the cycle?

    No use 000 instead of 5 and then add a 5 minute defer. The 005 after feed doesn't operate if the feed is cancelled for any reason.
