Apologies for the delay in getting back to you
I did post the times in the screen shots on the first page

Essentially the water change occurs every X days @ 750PM
At 750PM the skimmer and RTN pump turns off
Water Change Occurs
RTN pump gets turned back on
Wait 2 mins, then turn skimmer back on

In regards to your question, yes the exact same source is being used for the AWC as the ATO
The function is set to both AWC/ATO however only one function seems to work

The issue I have is that when I have made the changes recommended by GHL is prior posts, yes the ATO works perfectly, however what doesnt work is the AWC. The socket doesnt turn on when water is needed after the AWC water drain and instead I get a error on the level
