Didn't work for me. Nest won't configure complaining that it needs C for
power. I'm thinking to connect C from Navien to C on Nest but not sure
if that could damage Nest. Any thoughts? Appreciate.
Hi. Thanks for the info. My Navien boiler has R W C connection. There is
no G connection. I have the resister connection in parallel between W &
C but not sure how to connect the rest.
