Manual WC using DOS Question

[ddc0715]

when I set up my DOS to perform a manual WC do I have to change the seconds to equal 24hrs in the feed mode settings? the default value is 900 seconds (15 minutes) or does the apex know to override this once you configure the DOS to perform a manual water change.

You don't need to set the Feed timer value. All of the timing for the manual water change is handled by the programming on the two virtual outputs that are created when running the setup task:

[H2O_START]
Set OFF
If FeedD 000 Then ON
Defer 720:00 Then OFF

[H2O_CONTROL]
Set OFF
If Output H2O_START = ON Then ON
Defer 719:00 Then OFF

[DOS]
Fallback OFF
tdata 00:00:00,1,17,10,87,2,88,143,10,107,2,28,10,0
If Output H2O_CONTROL = OFF Then OFF
If SW_LOW OPEN Then OFF

The way it works is by linking these two outputs, each with a 12 hour Defer delay, resulting in the DOS running for 24 hours starting the moment you click the Feed button.
