Taco sr503 relay question
I'm only using zone 1 and 2 and the tt contact goes to the first tt input on the boiler.
I want to move the 2nd zone to the priority zone 3 and use the priority tt to the second tt input on the boiler to run a separate odr/temp curve. But I want the priority function inactive
I read the directions a few times and am a little confused. Do both end switch close when the priority zone calls for heat? If so it is going to kill my plan
