    Stop AWV when fresh SW low

    How do I stop AWC when optical sensor on my saltwater tank is low?
    Will code below work if I add it to each of the DOS head that do the AWC?

    If Salt_L OPEN Then OFF
    Defer 000:10 Then ON
    Defer 000:10 Then OFF
    Min Time 060:00 Then ON

    Yep, except you want Min Time to be OFF not ON.

    Can you please explain why?
    my logic is that once water is back in the fresh saltwater tank I want it to wait at least an hour before the AWC can resume so I have enough time to get salt mixed in.

    I assumed that you were using it to prevent short cycling. For the purpose you indicated, you actually want defer then ON not min time.

    thanks for the help!!

    Updated as below. wait 20 seconds to make sure before turning off, then once the low sensor covered again wait 2 hours before any AWC starts again. Have same code for each of the DOS heads

    If Salt_L OPEN Then OFF
    Defer 000:20 Then OFF
    Defer 120:00 Then ON
