    ATU auto top up program review

    Hi guys,

    Could someone please have a look at this program before I use it. I have one float switch at the moment (intend to add more) and when the sump is full the switch is open and when the water is low the switch is closed. This program will be for R.O. to be added, but I also have another automatic top up to set up to contain salt water. I want my ATU to run if the Float is closed (water is low) and the salt is above 35.5, but not to run if the salt is below 34.5. If the float is closed then the ATU will be off, if my return pump is off then ATU off. I dont want the ATU to run for more then 1min every hour. When the ATU does run it should stay on for a minimum of 30 secs at a time and max of 1min, it should defer for 1min before switching on under any of the circumstances.

    Thanks as always.

    Fallback OFF
    Set OFF
    OSC 000:00/001:00/059:00 Then ON
    If FLOAT = CLOSED Then ON
    If Salt > 35.5 Then ON
    If Salt < 34.5 Then OFF
    If FLOAT = OPEN Then OFF
    If Outlet Return-Pump = OFF Then OFF
    Defer 001:00 Then On
    Min Time 000:30 Then On

    Looks good to me. Had to check my defer and min knowledge, but it will wait one minute from when it could switch on until out actually does, then always run for at least 30 seconds.
