Steam-Help with Thermostat wiring, New Yorker 2 wire
-New Yorker Boiler.
- T Stat something no longer made
looking to put in a Wifi Thermostat for remote functionality.
Only steam heat no AC.
I am certain this topic has been answered somewhere, however I have not been able to pinpoint some finer details reading through various discussions. I am trying to identify how I can add a C Wire to the current wiring scheme. Upon review of one of the manuals diagrams it appears there are two places the t stat wiring goes to which is blue and brown on each one. I don't know if it is possible to connect a third wire somewhere to be "C" or do I need to apply one of the methods noted throughout the web, which is adding an external transformer, add a wire etc for an Ecobee or nest t-stat.
Attached you will find the wiring diagram pulled from the manual.
Thanks in advance!
