The power is supplied by a transformer, and when the thermostat makes contact between the 24 volt power and one or two of the other wires, a relay back at the heating/cooling unit activates the corresponding heat/fan/cool function of the unit(s).
With Nest, the thermostat controls only the boiler, so it heats the whole house and can't control individual radiators. With the 3rd-gen Nest, you can also control a hot water tank, but if you have a combi boiler, then this feature is redundant.
