Automatic Water Change Not Running

[kelpfly]

Hello,

I'm trying to setup an automatic water change but I am not able to get it running when trying to test it. I set a schedule as I would like it to only go off once or twice a week, but I tested it without a schedule and wasn't able to get that working either. I've attached photos of my settings for the ATO, Fill and Drain pumps as well as my schedule settings. I would appreciate any help that I can get!

Also, a secondary concern, but I was wondering if it would be possible to set my skimmer to turn off during the automatic water change. Right now I have it depending on the status of my return pump and turning off if that is off, am I able to have the skimmer's state depend on multiple statuses?

For one you don't want to turn off anything that will affect the normal running water level since the AWC uses that water level. Also the AWC output does need to control you ATO pump since the water level sensor needs to be wet to start the AWC. and the fill pump will run till it is wet again when filling back up. So you can only change an amount that will not cause an issue with your return pump running or the skimmer. I do my water change split into 4 times a day. Since any more at one time would drop the water level too low in the sump for it to work.
