Hi All - new to the forum and would appreciate some expert guidance
I would like to install a Nest to control the boiler. the old thermostat used 2 wire (R & W), which are connected to CN10 on the NHB board. I have added a blue and green wire to provide power to the thermostat but don't know where on the NHB board these wires should go.
below are pictures and would appreciate the advice.
