Hi I have a Williamson-Thermoflo GWA series 2 gas water boiler.
Thermostat is installed with 2 wires only. I have a Nest thermostat that sometimes has issues and it was recommended to have a C wire for better power supply.
Is it possible to get a C wire from this boiler? This is a screenshot from the manual, and it has a wire labeled C. Is this the correct wire or would I need additional hardware to get a C wire installed?
Thanks!
