Thanks Ray.

I noticed that for the valve driver, you have 8 TVS, my understanding is, the TVS needs to be connected in parallel to the protected circuit. Which is why you have one side connected to 24VAC, and another side connected to the valve. However, I don’t see 24VAC is connection to the expansion board port, so how does this work?
