    ATO and WATER CHANGE

    Good morning.
    I'm writing from Italy so sorry for my english. I'm trying to build a system that provides water for the ATO system (ATK) and water into the tank where i prepare saltwater for water changer.

    Of couse the ato system is ATK and instead of the pump it will command a solenoid valve.

    When I switch on a virtual outlet I want the rodi water to go to the tank where i prepare salt water, in this tank I will install another water level mechanism in order to obtain
    a good safety.

    You can find attached a picture.

    Thank you

    Paolo

    You want something like this

    NSWsolenoid
    Set ON
    If Output ATOname = ON Then OFF

    (Set outlet to AUTO when you want to fill. Set it to OFF after mixing)

    MainSolenoid
    Set OFF
    If Output ATKname = ON Then ON
    If Output NSWsolenoid = ON Then ON

    Yes, thank you.

    Then I will try to include also the level sensors to not have water overflowing from nsw tank.

    Thanks again

    If you have high and low level sensors for automatic filling start (I assumed by your description you only had a manual float valve) the you need to do it a little differently. Make sure power monitoring is disabled unless using it in an approved UPS application. If the apex reboots or loses power during a reservoir fill, you need to reset the FillNSW by setting to ON then to AUTO.

    FillNSW (VO)
    If LowOptical OPEN Then ON
    If HighOptical CLOSED Then OFF
    If Power Apex Off 001 Then OFF

    NSWsolenoid
    Set OFF
    If Output FillNSW = ON Then ON
    If Output ATOname = ON Then OFF

    (Set outlet to AUTO when you want to fill. Set it to OFF after mixing)

    MainSolenoid
    Set OFF
    If Output ATKname = ON Then ON
    If Output NSWsolenoid = ON Then ON

    Zombie, thanks a lot!

    My idea is to buy a second ATK to use the sensor assembly (2 optical - 1 float) in the NSW tank to achieve maximum safety.

    What do you think?

    FMM can only do opticals not floats.

    I would not buy an ATK, but instead get an FMM and as many OS-1 with magnetic mount as you want for the application. It will be cheaper and you need the mounts anyway.
