    ATO with Kalk Reactor and Solenoids

    Hi There,

    I tried to setup my ATO with a kalk reactor using 1 pump and 2 solenoids. The pump sits in the fresh RODI reservoir and when the float sensor is triggered it pumps water into the sump. It currently goes to a splitter and flows throw the normally-opened solenoid to the Kalk reactor. The other end of the splitter goes to a normally-closed solenoid to the sump bypassing the Kalk reactor. Both solenoids are connected to outlet #3 (SX3).

    How would I code something for the desired effect below?

    If PH > 8.3 AND Sump_Switch Open then SX3 On

    I don't want to power the solenoids all the time unless the switch is open and the PH level is high.

    Thanks in Advance!

    Fallback OFF
    Set OFF
    If SX3 OPEN Then ON
    If pH < 8.3 Then OFF
    Min Time 015:00 Then ON

    Zombie, I am not sure I follow your program, where would that be entered? (I am just curious on this program, I find it interesting. Haha)

    I would think this would require some Virtual Outlets. I would run the pump just off this:

    ATOPUMP
    If Sump_Switch Open Then ON
    Defer 000:10 Then ON
    Defer 000:20 Then OFF
    Min Time 015:00 Then OFF

    This will only run if the switch has been triggered open for 10 seconds and stops once it has been triggered closed for 10 seconds and only runs once every 15 mins (this is what my ATK is set to)

    Create this Virtual Outlet:

    Virtual Outlet PHHIGH

    Set OFF
    If PH > 8.3 Then ON

    And this is your solenoid outlet:

    SX3 Outlet

    Set OFF
    If Outlet ATOPUMP = ON Then ON
    If Outlet PHHIGH = OFF Then OFF

    So what this SHOULD do (I am also fairly new to this, so getting to grips with it) is only turn the SX3 outlet on only if the PH is above 8.3 AND while the ATOPUMP is running else it will be off.

    I have a similar setup to the diagram below. Both of my solenoids and powered off of the same APEX outlet.

    I reviewed your coding and I'm not quite sure it's doing what I'm hoping it would do. I'm basically hoping to minimize the amount of time the solenoids have to be on so how would I write a conditional statement where it would only turn on if the PH > 8.3 AND the Sump low water switch is open?

    Currently this is what I have for the solenoid outlet:
    Fallback OFF
    Set OFF
    If pH > 8.3 Then ON
    If pH < 8.2 Then OFF
    Defer 000:15 Then ON

    But unfortunately this would create a situation where the solenoids would always be powered above 8.3 regardless if the sump level is low or not.

    That is the code for his two solenoids sharing one outlet. No VOs are required.
