Apologies for the delays

OK, so what I currently have is one set of sensors set up for AWC.
The AWC is setup to shutdown the Skimmer first, turn off RTN pump, then wait for X period of time, activate the water pump #2 to empty the tank to a certain level, then activate pump #3 to fill with natural sea water. Once level X is reached, return pump is turned back on, wait X minutes then skimmer turned on.

This worked fine until I added another level meter for ATO
I have a 3rd level meter that sits in another part of the sump. This is used for ATO and is dis-activated for when AWC's occur
The issue is that either the ATO or AWC occurs, not both.

I have attached screen captures of all necessary (I think) settings of the Profilux.
Id really appreciate any help as currently I'm doing the water changes using manual switching to get around the issue.

Thankyou in Advance
