    Tunze ATO programming help

    Hello. I am a first time Apex user and would like to incorporate some programming for my Tunze Osmolator ATO. I have spent the last week searching through this forum and Google and am not sure if the program I have is what I need for what I am trying to do.

    I need a basic program that:

    1. Automatically turns off the power to the ATO when my pump is turned off. (I currently have programming written to turn off the ATO when in "Feed" mode. How do I reword this so that the ATO is turned off when the pump is off, period? This will cover both feeding, maintenance, and any unforeseen pump issues which cause the pump to turn off.
    2. I would like a 5 minute delay from the time my pump comes back online to the time the ATO restarts.
    3. Apex turns off the ATO if the pH rises above 8.60 (security in case the sensors get stuck and the ATO keeps pumping water into the sump). Is there a way for the ATO to turn back on if the pH drops below a certain level, say 7.7? Or is this even necessary?

    Without the 5 min delay, the high water float switch activates and sounds the alarm while the water level in the sump goes down from the pump restart.

    At this point, I have the basic programming down for turning off the ATO pump (I think). Can anyone tell me if the 'FeedA 005 Then Off' is correct to give me the 5 min delay? If not, could you please correct?

    Thank you very much for your help...

    Current Programming:

    Fallback OFF
    Set ON
    If pH > 8.60 Then OFF
    If FeedA 005 Then OFF

    Rename "Return" to the actual outlet name of your return outlet.

    Fallback ON
    Set ON
    If pH > 8.6 Then OFF
    If Outlet Return = OFF Then OFF
    Defer 005:00 Then ON

    Thank you SO MUCH for this help! I tested this out today and it works perfectly! Just one other question - should the Fallback option be ON instead of OFF? The reference manual says this about ATO when it comes to the Fallback setting: "On the other hand, if your outlet controls your dosing pump, perhaps fallback OFF is more appropriate because the pump could fatally dose your tank." I dose Kalk using my ATO.

    Thanks again!

    It can really go either way with the Tunze. Basically it's a choice between complete loss of ATO under Fallback or ATO without pH safety. Up to you which one feels safer.

    Would it be a matter of adding a simple OR statement if I have 2 return pumps and want the Tunze off if either one is off?
    Fallback ON
    Set ON
    If Outlet Return1 = OFF OR If Outlet Return2 = OFF Then OFF
    Defer 005:00 Then ON

    You can't use Or statements. Just write two separate lines.

    If outlet return1 = off then off

    If outlet return2 = off then off

    How is this:

    Fallback ON
    Set ON
    If CondX4 < 31.0 Then OFF
    If Outlet RETURN1L_3_5 = OFF Then OFF
    If Outlet RETURN2R_3_4 = OFF Then OFF
    Defer 005:00 Then ON

    I want the ATO to switch off if either pump is off or if salinity drops below 31. It switches back on 5 minutes after all 3 conditions are fulfilled. So if one pump switches off, then is switched on, but the other pump switches off in the meantime, the original pump swtching back on alone won't turn on the ATO.

    That would do the trick, but you might want the defer to be a little longer since tunze ATOs prime every time they go from off to on. 30 minutes would probably be better

    Thanks zombie I'll use this code! What does it mean that tunze ATOs prime and what are the implications? Sorry first time ATO and Neptune user here.

    It turns the pump on for like a minute when it first turns on. The implications of that is if the salinity ever hovers around that 31 value, it can turn on and off quite a few times, which would dump 1 minute of water every time it changes from off to on regardless of the float state. Stupid design idea from Tunze, but a 30 minute defer would prevent this from being an issue without negatively impacting other times it turns off (like when the return turns off)

    I would just turn off the Tunze ATO if the water is passing the warning level which should not happen all the time. Like a double protection in case the Tunze acts up and keep pumping fresh water to the tank.

    Would this be the correct programming to include the ATO in Feed Modes (i.e. turn on 30 minutes after Feed Mode), or would this make the ATO switch on 60 minutes after Feed Mode (30 minutes Feed Mode + 30 minutes Defer):

    Fallback ON
    Set ON
    If Condx4 < 30.0 Then OFF
    If Outlet Return1L_3_5 = OFF Then OFF
    If Outlet Return2R_3_4 = OFF Then OFF
    If Power Apex Off 001 Then OFF
    Defer 030:00 Then ON
    If FeedA 030 Then OFF
    If FeedB 030 Then OFF
    If FeedC 030 Then OFF
    If FeedD 030 Then OFF

    That would be 60 min. Use 000

    Ok great thanks! I assume 000 should be used for my skimmers too which have similar Defer statements for when the pumps go off

    Yeah. They add up so the same would apply to the skimmer

    I was wondering if someone could look at this and tell me if I need to have the EB_8 line of code in there. I want it to defer 20 min anytime that it turns off, even when the power goes out to the EB_8. Thanks
