https://www.googlenestcommunity.com/t5/Nest-Thermostats/Boiler-control-with-multiple-zones/m-p/159353#M32845 <P>I recently upgraded my boiler to a high efficient boiler. My old boiler ran on loop temperature but this system needs a signal from a thermostat to run and I cannot run wires from all of my thermostats to the boiler. Does Google have a product that I can link with my nest thermostats that will send a dry signal to the boiler? I read about a Heatlink product, but it looks like it is only available in Europe</P> Wed, 11 May 2022 15:17:20 GMT Gr8Save 2022-05-11T15:17:20Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Boiler-control-with-multiple-zones/m-p/159353#M32845 <P>I recently upgraded my boiler to a high efficient boiler.
