Nest Thermostat Not Getting Power

I am trying to install a Nest thermostat in place of my Lux TX1500E Smart Temp Programmable Thermostat. The Nest is telling me the Rh isn't supplying enough power. I have Weil-Mclain WGO3 Oil Boiler with a Carlin 60200 Primary Control. The Carlin says it is 24 VAC and the 2 thermostat wires come directly from the TT on it. Is it even possible to install the Nest on this system? Do I need to have another transformer added? Any help would be greatly appreciated. Thanks.

    is your thermostat wired directly

    to the carlin primary control? or to the aquastat?  If aquastat, which one is on your boiler.
