Yes, you have to download. When I selected download, it allowed me to open the PDF.
I'm not familiar with the brewtroller, but the AC looks good to me. You could run one pump off L1 and one off L2, for balance, but that is really minor.
So... the low voltage... yep needs some work
I'm assuming the brewtroller output is +12vdc... looks like you have +12vdc going to both sides of the SSRs ??
I'm assuming you can replicate the switches in my drawing and substitute the BCS outputs for the brewtroller outputs.
