ATO Fill and AWC Drain occurring at the same time

I noticed this recently after disabling the AWC/ATO functions to service the tank. I turned them back on, and shortly after an AWC schedule turned on. I heard the ATO pump toggling on and off to keep up with the drain.

Normally this functioned well, my salt levels are good and AWC tank was depleting as expected.

They should not run at the same time. Suspect it may be an order of operations bug. Also possibility the Depends may be triggering the ATO function. Would you mind sharing screenshots of your Changer output, Auto Water Change schedule and logs associated with Changer? Briefly describe your steps upon completing the service and how you came to know both output devices were active. We can try to help here but it actually may be best that you gather this info and submit to support@coralvue.com. @Carlos @Don
 
Where you trying to keep the AWC from happening or did you want them all off? I have a switch in a button box that I use to disable the AWC. It won't stop one once it has started but will keep one form starting. It does mot disable the ATO though. I did that by creating an output that is on when the switch is on. I use that output in the depends on in the AWC schedule and set the dependency mode to off if on. So if that output is on the schedule will not start any AWC sequences.
