@dylanbeck2, step 5 is correct:
The wiring diagrams are my best friend …let’s break down your setup:
The controller outputs 24VAC, as such we want the 24VAC leads from the relay going to the controller:
We see these wires in your other community thread’s photos…
Note the 24Vac labels, which are spliced to a black and white wire that go out the top of your relay box…
However, I don’t see the black wire coming into your wallmount…
The white wire appears to match the thickness of your pump relay wire, but I believe the black wire you have connected comes from the multi-strand wire (unless the black wire is hiding behind the multi-strand, but the thickness appears to be thinner).
Is the black wire hiding somewhere? Did it get spliced into the multi-strand somewhere? I remember you mentioned one of the wires is spliced into the valve common then connected to the com (yellow) – do you have a photo of this by chance? We might want to consider un-splicing this to simplify the the possible wiring interference you’re seeing.
I hope this helps.
