    Manual button to generate RODI - programming question

    Hey guys

    Hope you're well. So I have 3 electric valves/solenoids connected to my RODI system and powered by my apex power bar. Currently, I have them working twice a week on a schedule to automatically fill up my RODI reservoir. However, I would like to now also create a manual button (either through feed mode or through a virtual outlet) to generate some fresh RODI water on demand. I tried a few commands, but it doesnt seem to be working.

    Currently, to fill up my RODI bucket, it takes about 60 minutes. Valve1 opens the main water line. Valve 2 opens the RO flushing/waste water. Valve3 directs the water into the DI. So basically what my current programming is: open valve1 for 60 minutes while simultaneously opening valve2 for 2 minutes to flush. After 2 minutes, valve2 shuts down while simultaneously valve3 opens up. After 60 minutes, valve1 and valve3 both shutdown, while simultaneously valve2 reopens for only 1 minute to release excess water and pressure.

    Your help would be much appreciated! thanks

    Valve 3 is unnecessary. When valve 2 flushes the system, there is not enough PSI to actually drip any water through your DI stage. I would remove it altogether since it's just an extra failure point.

    MainSol
    Fallback OFF
    Set ON
    When On > 060:00 Then OFF

    StopFlush (VO)
    Set OFF
    If Output MainSol = ON Then ON
    Defer 002:00 Then ON

    FlushSol
    Fallback OFF
    Set OFF
    If Output MainSol = ON Then ON
    If Output StopFlush = ON Then OFF
