I'll assume the AWC is running according to the DOS graphical scheduler as set up from the Fusion task. I'll also assume these sensor names, since sensors are limited to 6 characters:
Old_Hi -- CLOSED when water is high
New_Lo -- OPEN when water is low
You just need to add a couple commands under the Advanced tab of both DOS heads.
If Old_Hi CLOSED Then OFF
If New_Lo OPEN Then OFF
Now the DOS will continue running its regularly scheduled water changes, but if either of the sensors are triggered, it will stop adding and removing water until you correct the situation.
You can also add these commands to your EmailAlm output to alert you of the conditions:
If Old_Hi CLOSED Then ON
If New_Lo OPEN Then ON
