Programming IM Hydrofill ATO with Apex

[Mahi442]

I’m new here (first post) and recently got back into the hobby. I just setup my IM Hydrofill TI ATO and trying to program it with Apex. I was looking for help/feedback on the script below.

First question would be is this written correctly? Should I program it differently/is there a safer/better way to do this?

I don’t have any leak detection yet for the apex but plan to get it, in which case I would add commands to this. What would be the commands I add to this for the leak detection kit when it comes or do those commands go in the LDK programming instead of the ATO programming? Or what would be recommended to get/do as a backup to shut off the ATO in case something fails if there’s a better idea than the LDK.

Any advice would be greatly appreciated, thank you appreciate it.


Fallback OFF
Set ON
If Output RetPump-4 = OFF Then OFF
Defer 005:00 Then ON
If Salt < 32.0 Then OFF

I adjusted the script to this

Fallback OFF
Set ON
If Output RetPump-4 = OFF Then OFF
If Salt < 32.0 Then OFF
When On > 005:00 Then OFF
Defer 015:00 Then ON

I'd remove -
If Salt < 32.0 Then OFF The Conductivity probe in my experience is not consistent enough that I'd trust it
When On > 005:00 Then OFF The Apex has no idea how long it was running as it doesn't communicate with the Apex.
