Im looking to add a failsafe to my ATO. I am setting up an awc system and want to prevent the ATO from taking over if the New Salt water pump fails to deliver the new water. The ATO turns on 4x a day for 5 minutes. Sw1 is the normal operating level float switch and it is open when the water is at the correct height. The water change system turns on a pump, connected to a drain, immediately after the ATO’s 5 minutes are up. It runs until a low water float switch is triggered. Then the new salt water pump runs until the sump returns to Sw1’s normal operating position. I want to turn off the ATO and send an alarm if the low water float switch is engaged, or if the normal operating switch is not in the correct position after the NSW pump had a chance to fill the tank. This is all controlled by time and float switches so basically if the float switches aren’t where they are supposed to be after the time the NSW pump had to run, then I want the an alarm sent and the ATO off until I manually reset it.
Is there a way to get the ATO outlet to default to off and require manual override to turn back on if a virtual outlet is triggered on?
