    Alarm for flow activity when solenoid is off

    How can I code for flow activity in a rodi line if the neptune solenoid is in the OFF position? I want to get a heads up if the solenoid fails and water comes through the line. I have a 1/4 inch sensor on the line and im stuck because theres no "and" statements.

    This is what im hung on so far in the virtual outlet alarm I made:

    Set OFF
    Fallback OFF
    If RODI > 0.0 Then ON
    ??????????????

    I really want the "and" capability directly after the last command above, and would use it for: "AND outlet Solenoid = OFF"
    But theres no "and" - so how can this be done?

    Set OFF
    Fallback OFF
    If RODI > 0.0 Then ON
    If Outlet Solenoidname = ON Then OFF
    Defer 000:10 Then ON

    Do be warned that the flow meter won't sense a small trickle. It would need to go full blast on the RODI to not read zero with the 3gph minimum.

    You might be an engineer if...You have no life and can prove it mathematically.

    Awesome. Full blast is better than nothing. This will be the 6th line of protection/ warning on my auto ato system.
