Thanks Steven,
It seems to work fine. You have to love the versatility of Aquacontrollers. I've been using the If X>Y Then do whatever. Did they do away with using the then in the new program or what? I haven't tried not using the Then command. Just curious, I put the Then in the program and it seems to work fine. Unless my owner's manual is out of date since it's AC2.
Thanks again.
