> Check pg 23 of the installation manual for proper wiring.
Thanks Freon, I was waiting for you to get back online.
I've read through that entire document a few times & on page 23, note 4, it states that if I have Y1, W1 & W2 then stop & call a contractor, not explaining the wiring further.
Looking at that page I am good with R, O, Y, G & C. I have no L nor E (X or X2). I can put W into Aux, but where do I then put W2
