You asked the same question on the Neptune Facebook group, and I replied with a question, but you didn't answer it there.

Please don't cross-post to different forums as it just leads to confusion on tracking the conversation.

For those following along here on R2R, here's the solution I posted to the Facebook group:

You'll need to create two virtual outputs, one that tracks the Alkx reading, and one to act as the 4 hour timer, then reference that output in the Advanced tab on your DOS:

[Pause_Alk]
Set OFF
If Alkx# > 9.2 Then ON
If Output Alk_Timer = ON Then OFF
(substitute # in Alkx# with the AquaBus address of your Trident)

[Alk_Timer]
Set OFF
If Output Pause_Alk = ON Then ON
Defer 240:00 Then ON
Min Time 120:00 Then ON

Place this code into your DOS Advanced tab:

If Output Pause_Alk = ON Then OFF

If you're not familiar with virtual outputs, see my tutorial here:
