Nest Thermostat 3rd Gen,and  just 2 line W and R wired.
If you have old gas boiler, you will be confuse. because almost all of wire diagram is 3 or 4 lines. so I bought a nest thermostat, and I have an old boiler system since 1940. so I tried wiring to my nest and gas boiler. it was 2 wire only system. W and R. I confused it diagram, but It was connected. great working now. you can connecting to old gas boiler. just 2 wired is ok.
some thermostats are using AA or AAA battery powered. I thought power problem, where is my power line from nest? but It is ok. your nest will power on. just 2 wire! you don’t need pro installer. you can do!
