I'm upgrading my Doorbell Transformer. I already connected the house wire to the Transformer, but the doorbell wiring got me confused.
I have two white wires that I know will go together and Then I have one black wire. Don't know which screw to connect it too on the diagram. I see the two spots for the 16v which is the minimum and the two spots for the 24vac.
Which side does the white one go to and which side does the black go to?
