    DOS unit program for Neptune ATO/ATK

    So I really was trying to avoid asking this.... but I can't seem to program my ATK unit with my DOS unit correctly after trying a few programs I found on here. What I want to do is dose 1.5 gallons and have the first sensor(Swx5_1) be the main water level sensor, and the second one above it as a back up(Swx5_2)

    I Haven't changed anything from factory settings in the ATK, and this is my current program(copied from forum stickey) under my H20 top off dose pump:

    Set OFF
    If Swx5_1 CLOSED Then ON
    If Swx5_2 OPEN Then OFF
    Defer 002:00 Then ON
    Min Time 010:00 Then OFF

    Then under my dos wizard I added my estimated evaporation amount of 5678.1ML to dos between the hours of 15:20- 23:59



    Currently both Swx5_1 is open, and Swx5_2 is open and no water is getting topped off and my sump water level is getting way to low.

    Change the code in the advanced window to this.

    If Swx5_1 CLOSED Then OFF
    If Swx5_2 CLOSED Then OFF
    Min Time 010:00 Then OFF

    Also make sure that you give a buffer to the estimated evaporation level. It should be between 1.25-2x how much typically evaporates.

    Thank you, I will delete what I had and try this. 5678.1 is about 1.5 of my evaporation, so I think that will work.

    Just so I avoid being annoying and keep asking program questions, how does the pump know to turn on if nothing states "ON" in the code?

    Its default state is what is in the wizard, so in this case there shouldn't be a statement telling it to turn on.

    @ zombie. Can you please send me the complete directions and code for me to set my dos for ATO? I have a couple opt sensors if needed. I would greatly appreciate it
