    ATO Programming

    I have a single FMM optical sensor in the filtration section of my frag tank controlling the power to a 50ml per minute BRS dosing pump. I only had one FMM port available and limited space to work in.

    I noticed that my dosing pump was still running even though Swx11_4 was closed (both in fusion and visibly). I do have the dosing pump plugged into outlet 1 on one of my EB8s since the 4 and 8 outlets are taken up by heaters and chiller.

    Is there something wrong with my code that may have caused the pump to continue to run even though the switch was closed? If not, any suggestions on ways I can prevent this? From what I can tell, my frag tank needs about 0.5 gallons per day and I was planning to start adding Kalk to the top off water, if I can get to a spot where I am not worried about ODing.

    Below is my ATO code for my frag tank:

    Fallback OFF
    Set OFF
    If Swx11_4 OPEN Then ON
    If Swx11_4 CLOSED Then OFF
    Defer 001:00 Then ON

    Thanks!

    BRS dosing pumps do not work properly on EB8 outlets other than 4 and 8.

    What size is your heater? If it is 500w or less, swap the heater and dosing pump outlets and programming.

    Good to know, so I am not nuts. I think I can swap it with the chiller, since I don't remember the last time it ran since getting central air in my house. If my chiller did switch on in outlet 1 could it cause problems? Per my calculations, the chiller is about 690w.

    Moving the chiller to outlet 1 is a no-go - it exceeds the 5A limit of the outlet.

    It appears that both of my heaters are 500w, so probably safer to go with one of those.

    If I add Kalk, this code would work right?
    Fallback OFF
    Set OFF
    If Swx11_4 OPEN Then ON
    If Swx11_4 CLOSED Then OFF
    Defer 001:00 Then ON
    If pHx12 > 8.4 Then OFF
