I set up my DOS for daily automatic water changes. Can I program manual water changes to be done with the same DOS as needed? I’ve created a virtual outlet as I heard it would be necessary but don’t know how to program it.
Automated and manual water changes with same DOS!

Thanks! All I have are these DOS add and DOS remove programs. Is this what you need? I created a virtual outlet but don’t know how to set it up. What I’d like to do is have a set say 30-40 gal water change which I could do with the touch of a feed button when I feel I need an additional water change in addition to the standard daily one.

The first thing you need to appreciate is that the DOS can only change 31.7 gallons in a 24-hour period. In this example I've named your virtual outlet "DOS-M" (for manual DOS). To modify the DOS programming you'll need to click on this icon:
I've never used my DOS pumps for AWC, and I'm not 100% sure on the programming - mainly if "ON" will simply turn the unit on to maximum until it's told to turn off. Don't include anything in brackets ( ) or the ".........." dots in the programming (those are just for separation here).
DOS-M (« this is the new virtual outlet you need to rename; also add the new tile for it)
Fallback OFF
If FeedD 000 Then ON
Min Time 10:00
..........
*Note that I've gone with a short min time for testing to confirm whether this will work or not. If you want to run this for 24 hours then you'd need to revise this to "Min Time 1440:00".
DOS-Remove (« your existing DOS outlet)
Fallback OFF
<copy tdata here - this is your regularly scheduled AWC and should be 1 line>
If Output DOS-M = ON Then ON
Defer 000:30 Then OFF
DOS-Add (« your other existing DOS outlet)
Fallback OFF
<copy tdata here - this is your regularly scheduled AWC and should be 1 line>
If Output DOS-M = ON Then ON
Defer 000:30 Then OFF
..........
When you hit Feed mode "D" this should trigger the DOS-M virtual outlet to ON, which both DOS pumps should read and turn on manually, wait for the virtual outlet to turn OFF, wait 30 seconds and then turn both off (unless this happens to coincide with a regular water change in which case they'll continue running per your schedule).
