Hi
I do this in co2 controller of my apex
Fallback OFF
Set ON
If Time 09:00 to 18:00 Then ON
If kH > 8.30 Then OFF
but I want it to turn off 18, it stays connected after 18, following the configuration of kh, can anyone help ??

The program you posted has Set ON.

Also check that the slider for that output is in the AUTO, not the ON position.
