Help with ATO Setup


Recommended Posts

I'm trying to set my ATO up with two sensors. Unlike the GHL video option of one switch is low level, and one is high level I want one low level and one emergency shut off.

I have one switch working as On/Off for the ATO but for the life of me I can't get the float switch to shut the ATO pump off when triggered.

My setup:
- Optical switch is the "ATO Sensor"
- Float switch is the "High Sump Sensor"
- Y cable is being used from the purple input

My programming:

Figured this issue out and will post a tutorial in the main forum. I had the Outlet set to "Fill Water ATO," when it should have been pointed to my "Programmable logic." I also didn't need the float switch inverted.

I know this thread is old but I am trying to setup my ATO. I have my ATO with Optical as well and when water is low I want it so it will not turn on my pump. You said you have figured it out. Do you have a tutorial for this?

He never made a tutorial. Only the screen shots above.
