Hey guys Im sure this is a basic question and I appoligize if this is in the wrong place and im sure im going to hear all about how simple this is, but Im drawing a blank and don't want to fry anything. I am doing a boiler and using an sr503 switching relay with Honeywell v8043e1012. The red wires are the end switch and should go to the TT or RW on the switching relay. One yellow goes to the W in the stat and the other yellow goes to one terminal of the 24v transformer. The R on the t stat goes to the other transformer terminal. I think that's correct. If not correct me please. Also the next is will the extra transformer fry the switching relay since it has 24 volts?
