To everyone that posted here thanks for your help. Sorry I had a mindblock on the wiring parallel thing. I could not get out of my mind that the override switch had to have 24 vac on it in addition to the 24 vac on the thermostat. Daves picture cleared that right up in a hurry. I will remove the 110 hot wire coming to the C terminal on the S350 since I am not running a circulator straight off of it, nor do I need to go through the transformer and wire exactly the way his pdf shows and I am sure it will work.


Thanks again
