AWC Stop On Empty

[Blank]

Is there a way to terminate the AWC when my new saltwater tank is empty? Like run until there is no more new saltwater. I have a level sensor.

I mean run the schedule till its dry not empty the container.

Are you using the AWC regimen for the AWC?

 

[Blank]

yes

when I add the low level it takes away the drain duration. I want to run it until the saltwater is empty.

 

[Danny]

I don't quite understand what you are trying to do. Are you wanting it to run until it hits the low sensor in the sump?

I want to run the schedule until the new saltwater is low level.

So, I have a drain container and a fill container. I am doing a gallon a day which is hour and fifteen minutes a day. I want that to happen until the fill container reaches low level. I have 10-12 days capacity.

In other words, I dont want AWC to run if I have no "Fill" water.

To do it you may need to create a couple of outputs. These outputs would be virtual so you leave the output device to none. They are only used for logic. One would be for the low level sensor to make it an output. Set it to active when the low level sensor is dry. The other would be a combiner type that would have both the output triggered by the low level sensor and the output of the AWC as inputs. invert the AWC output input on the combiner. Also set it as an AND combiner type. That way the only time the combiner output will trigger is if the AWC is off and the low level sensor is dry. Just make sure the low level sensor is high enough that there is enough water for one change. Use the combiner type in the depends on setting in the schedule for the AWC and set it to off if on. So if the low level sensor goes dry the combiner will not go high until the water change completes.This should prevent the next water change from happening. Make sure and test it once you have it setup.

Wow! Thanks a lot, I will give it a shot.

So, I just made a "generic output" called LowNew Saltwater with the low level input trigger on wet. The AWC schedule is dependent on the "generic output" and it worked. Thought I would share a KISS solution.

Nice! A couple of things for others to remember:

• If you pause the "Schedule," it will only affect the AWC
• If you pause the AWC Output, it will affect BOTH the AWC as well as the ATO

So remember to pause the "schedule" and not the Output.

What Carlos said. I created a Virtual Generic output and then made my water change dependant on that output. I can toggle that virtual out off and it will not run the schedule but the ATO keeps running.
