It seems programmable logic is difficult to implement even for the experts.

Why not replace it with advanced commands? I'm not saying for everything, just for the logic - it would make it much easier and allow users customization which is the current weakpoint.

Like for example; I want to delay AWC to allow return to fill sump:
If AWC ON Delay 02:00 Then ON, then apply it to the socket of the return pump, etc.


The rest of the programming is plug-and-play; really easy to use but only weakness is PL currently. I think if you can fix it; it will solve a lot of problems.
