Wired Gen2 Doorbell with 3 wire Honeywell chime

Hi, 

I can't figure out how to wire the white puck that has 2 wires on my 3 wire doorbell. It's from Honeywell. See picture.

Maybe you have (3) wires because you have both front and back door buttons in your house?  If so only use the wire for the door you are installing doorbell onto.   So you would only use the one marked AC and then one of the C1 or C2 screw terminals.

Hi, I have only the front. The transfo is between AC and V/AC terminals. The push button is between V/AC and C1 terminals, as shown on the wiring diagram. The white puck as only 2 wires. Should I put it between V/AC and C1? It would be in parallel with the button.

I'm gonna guess that the C2 is connected for no reason other than to keep it from flopping around.   And yes it would be in parallel.  There is a number of Youtube videos you can check out.  Just search on something like "Nest Doorbell Puck Installation" and they should come up.  I found this one but it is for the previous NEST HELLO doorbell.  However they work the same way.

Hi, 

C2 is not connected and is meant for the rear doorbell. My white puck has 2 wires, not 4. I will continue to search for videos...
