    ATO Programin question

    HI Guys,

    I'm new APEX owner (2 weeks now) and I have a question so I program my ATO like this.

    My ATO outlet:
    Fallback OFF
    Set OFF
    If Sw1 CLOSED Then ON
    If Sw1 OPEN Then OFF
    If Output ATO_MAX_TIME = ON Then OFF

    And My ATO_MAX_TIME (VO)
    Fallback OFF
    Set OFF
    If Output ATO = ON Then ON
    If Output ATO = OFF Then OFF
    Defer 002:00 Then ON

    My ATO_MAX_TIME coming on 2 mins after my ATO and if ATO is running it will shut it down. But ATO will come back like 10-15 seconds later in ON/OFF loop keep switching every second. How I can program ATO_MAX_TIME to shut down ATO outlet and not get stock in ON/OFF loop?

    Sounds like the Sw1 floaf is bouncing, possibly due to water movement. I would put in a min time statement to keep it off for an hour or so before it could turn on again.

    Also, your if Sw1 Open then off and if output auto off statements are redundant to the set off. You could remove them for simplicity.

    Here are some good exemple on how to do this :

    Pump_ATO

    Fallback OFF
    Set OFF
    If Smp_Lv CLOSED Then ON
    If Output Max_ATO = ON Then OFF
    Defer 002:00 Then ON
    Min Time 015:00 Then OFF

    Max_ATO

    Set OFF
    If Output Pump_ATO = ON Then ON
    Defer 000:12 Then ON

    Would the "Min time 015:00 then off" run the pump for 15 minutes then shut it off?

    The min time makes sure when the pump turns off, it stays off for at least 15 minutes to prevent short cycling of the pump.

    His code above allows the ATO to deliver whatever the floats call for UP TO 12 seconds every 15 minutes.

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