    Solenoid Programming

    I am trying to program my ATO Solenoid Valve to turn on for 20 min every 4 hours but to not turn on if my salt probe reading lower than a certain level.

    Can anybody help with this?

    Thank you so much!

    Here is what I came up with... Does this work?

    Fallback OFF
    OSC 000:00/020:00/220:00 Then ON
    If Salt < 60.0 Then OFF

    What exactly are you hoping to achieve with this?

    I believe that should do what you need, the fun part about the Apex is to write something and test it works how you want and if not, tweak it. I would hope you are not looking for a salt level of 60... as that is almost double what it should be in a reef

    That does do what you desire, but why are you using 60? That's really high. Did you leave it on mS/cm instead of using ppt?

    Thank you... it appears I got a defective Solenoid. I hear it click on/off but it doesn't open to let water flow through it. I emailed support but also just ordered another one. My salinity is 1.024 verified by my refractometer. The probe was calibrated and I did check to make sure it said ppt. It seems to have stabilized at 65 for 1.024. I guess I'll email support for that too. Thank you!

    Make sure the arrow on the solenoid is pointed the right direction.
